In metal press working, a tool that forces a metal to pass through a die under the action of an external force, a metal cross-sectional area is compressed, and a shape and a size of a desired cross-sectional area is obtained is called a draw die. Drawing dies are widely used, such as high-precision wire materials used in electronic devices, radar, television, instrumentation and aerospace, as well as commonly used tungsten wire, molybdenum wire, stainless steel wire, wire and cable wire, and various alloy wires are all pulled by a diamond wire drawing die. Made out of the diamond drawing die due to the use of natural diamond as raw material, which has a very strong wear resistance, high service life. The production process of drawing die inserts includes several process steps such as die pressing, draft drawing and turning. Drawing die is a wire through a mold to make it from coarse to fine, and gradually reach the size required by people. This special type of die is the drawing die. The drawing die is generally made of natural diamonds, synthetic diamonds (synthetic diamonds There are GE, PCD, synthetic materials, etc.) Copper wire drawing die is a soft wire drawing die. There are hard wire drawing die, such as pull tungsten wire, tungsten wire drawing die compression zone angle is relatively small, generally in 12Cermet Inserts – 14 degrees. Drawing dies include diamond drawing dies, hard alloy drawing dies, plastic drawing dies and the like. Drawing die usually refers to a variety of metal wire drawing molds, as well as pull fiber drawing die. The center of all drawing dies has a certain shape of hole, round, square, octagonal or other special shapes. As the metal is pulled through the die hole, it becomes smaller in size and even changes in shape. A steel mold is sufficient for pulling a soft metal such as gold or silver, and there may be a plurality of holes of different diameters in the steel mold.Drawing dies are widely used, such as high-precision wire materials used in electronic devices, radar, television, instrumentation and aerospace, as well as commonly used tungsten wire, molybdenum wire, stainless steel wire, wire and cable wire, and various alloy wires are all pulled by a diamond wire CNMG Insert drawing die. Made out of the diamond drawing die due to the use of natural diamond as raw material, which has a strong wear resistance, a very high service life.1. When the soft metal (such as gold and silver) is used, the steel mold is enough, and the steel mold can have a plurality of holes with different diameters.2. Cemented Carbide Dies—Tungsten carbide nibs are generally used for drawing steel wires (steel wires). The typical structure of this type of die is a cylindrical (or slightly tapering) hard alloy core close together. The ground is embedded in a circular steel case with Bell radius, Entrance angel, Approach angle, Bearing, and Back relief.3, steel wire mold – pull non-ferrous metal wire, such as copper, aluminum, and more similar to the wire drawing die, the shape of the hole is somewhat different.4, polycrystalline silicon mold – pull thin line can be used to polycrystalline diamond (synthetic diamond), as well as the use of natural diamond drawing die.Carbide wire drawing die adopts high-quality hard alloy as the core, which has high hardness, good thermal conductivity and small friction coefficient. Carbide wire drawing die (tungsten steel die) uses high-quality hard alloy as the core, with high hardness, good thermal conductivity, and low friction coefficient. Carbide wire drawing die is simple in production, corrosion resistance, strong impact resistance, low price is a prominent feature of this product, suitable for the drawing of ferrous metals, large size wire, and poor drawing conditions. Cemented carbide is an alloy material made by a powder metallurgical process from a hard compound of refractory metal and a bond metal.Carbide has a series of excellent properties such as high hardness, wear resistance, strength and toughness, heat resistance, corrosion resistance, etc., especially its high hardness and wear resistance, and it remains basically unchanged even at a temperature of 500°C. , It still has high hardness at 1000°C.Cemented carbide is widely used as a tool material, such as turning tools, milling cutters, planers, drills, boring tools, etc., for cutting cast iron, non-ferrous metals, plastics, chemical fiber, graphite, glass, stone, and ordinary steel, but also for cutting. Heat-resistant steel, stainless steel, high manganese steel, tool steel and other difficult-to-machine materials. Carbide has a high hardness, strength, wear resistance and corrosion resistance, known as “industrial teeth” for the manufacture of cutting tools, cutting tools, cobalt and wear parts, widely used in military, aerospace , Mechanical processing, metallurgy, oil drilling, mining tools, electronic communications, construction and other fields, with the development of downstream industries, the demand for hard alloy market continues to increase. In the future, high-tech weaponry and equipment manufacturing, cutting-edge scientific and technological advancement, and rapid development of nuclear energy will greatly increase the demand for high-tech and high-quality and stable carbide products. In the drawing industry of metal products, drawing dies are very important consumable tools. The choice of wire drawing die plays a key role in the quality of the wire drawing die. The physical and chemical properties of wire drawing die must meet the requirements of high hardness, impact resistance, wear resistance, and low friction coefficient. At present, there are carbide die, polycrystalline die and CVD diamond die on the market. Carbide wire drawing die has a lower life than polycrystalline silicon and CVD diamond die, but its cost is relatively low, so it is widely used in the wire drawing industry, and is particularly suitable for drawing wires or profiles with larger diameters (above 8 mm). Carbide drawing die core is generally made of tungsten carbide as a raw material and sintered with a certain amount of cobalt as a binder. Since the binder cobalt has low tensile strength and microhardness, in the wire drawing production, sticking wear and abrasive grain wear easily occur at the contact surface of the wire and the die hole, thereby affecting the ultimate life of the drawing die.The failure of wire drawing die can be divided into two types according to the time of occurrence: normal failure and early failure. Normal failure: After a large number of production and use of the drawing die, natural wear or slow plastic deformation and fatigue cracking occur due to friction. After normal service life, failure is a normal phenomenon and normal failure. Early failure: The mold does not reach the specified time limit for design and use, and it will not only fail due to chipping, chipping, breaking, etc., but also will be unable to continue service due to severe local wear and plastic deformation. For the early failure of the mold, it must look for the reasons for its production, and strive to take remedial measures. After decades of development, many new drawing die materials have emerged. According to the types of materials, wire drawing die can be divided into alloy steel die, hard alloy die, natural diamond die, polycrystalline diamond die, CVD diamond die, and ceramic die. The development of new materials has greatly enriched the application range of wire drawing dies and improved the service life of wire drawing dies.With the deepening of reform and opening up, the domestic industry has successively introduced wire drawing die and corresponding die hole testing instruments manufactured by industrially advanced countries. Through the analysis of foreign wire drawing die holes, we have learned the design ideas of modern wire drawing die holes and provided references for improving the design level of Chinese wire drawing die. The structure of the wire drawing core can be divided into five sections according to the nature of the work: entrance zone, lubrication zone, work zone, calibrating zone, and exit zone. The inner diameter profile of the drawing die is important. It determines the tension required to compress the wire and affects the residual stress in the wire after drawing. The role of the various parts of the core is: the entrance area to facilitate threading and prevent the wire from scratching the wire drawing die from the inlet direction; lubrication zone, through which the wire can be easily brought into the lubricant; the work area, is the main part of the die hole, wire deformation The process proceeds here, reducing the original section to the required section size. When drawing the conical metal, the space occupied by the volume of the metal in the working area is a circular table, which is called the deformation area. The conical half angle α (also called die half angle) in the work area is mainly used to determine the size of the pullout force; the role of the sizing area is to obtain the exact size of the drawn wire; the exit area is used to prevent the wire exit from being unstable And scratch the surface of the wire.With the increase of wire drawing speed, the service life of wire drawing die becomes a prominent problem. Americans T Maxwall and E G Kennth proposed a new wire drawing die theory for high-speed drawing, namely the “linear” theory. The drawing die made according to this theory has the following characteristics:1 The entrance zone and the lubrication zone are combined into one, which has the tendency to reduce the lubrication angle, so that the lubricant receives a certain pressure before it enters the working zone, thus achieving a better lubrication effect.2 The entrance area and work area are lengthened to establish a good lubrication pressure, and the angle is optimized according to the drawing material and the compression ratio per pass.3 The sizing zone must be straight and of reasonable length.4 The vertical line of each part must be straight.See our tungsten carbide nibs for wire drawing die

It’s axiomatic in the metalworking industry that for Carbide Milling Inserts quality production, a measuring gage has to be ten times more accurate than the part it measures. “We call it a gage R&R of ten percent,” says Willie Michaely, quality assurance manager of NCI, Inc. (Asheville, North Carolina) of Dowty Aerospace and a member of the British TI Group.
NCI is a 35-year-old precision machine shop specializing in rotating parts for aerojet engines. Its major customers include General Electric and Pratt & Whitney in the United States and Snecma (France) and Alfa Romeo and Fiat (Italy)—all manufacturers of gas turbine engines used in civilian and military aircraft as well as power generation machinery. NCI manufactures all types of rotating parts, including turbine rotating air seals, cooling plates and blade retainers, among others.
The company needs precise part measurements required by such high-performance machinery. More than ten years ago, NCI was using instruments that had a smaller capacity and less accuracy than it needed. The company decided to purchase the Fowler/Trimos horizontal setting family of instruments from Fred V. Fowler Co., Inc. (Newton, Massachusetts) to replace these. “When we were reviewing available measuring devices, compared with others, this Swiss-made setting system had significantly better accuracy,” Mr. Michaely says. “Of equal significance to us was its ease of use and the brief training needed.
“They are accurate down to the millionths. If my parts need to be ±0.001 inch, then the gage has to be accurate within ±0.0001 inch, which these Fowler/Trimos setting gages are,” he adds.
NCI’s companywide quality program not only meets ISO 9002 certification but also AS 9000, which adds 40 additional elements to the required ISO ratings, says Mr. Michaely. The program, clearly required by the tight tolerances involved in sensitive rotating machinery such as gas and steam turbines, has been in place for several years.
“Our customers demand our adherence to extremely tough quality standards, because when turbines fail, the downtime costs are enormous for their customers,” he adds. “Every part has its own serial number, and records must be kept on it from raw material through manufacturing for its lifetime.”
The company now has two models of the system. The 40-inch model of the Trimos system was the first one purchased some ten years ago, while the newer 60-inch version has been in service for a little more than a year, reflecting the larger size components being manufactured today.
Revamped and improved, the latest model with digital readout features a new scale and electronic display unit on which functions have been adapted to meet horizontal measurements such as MIN/MAX; RS232 data output; and accuracy of 0.000250 inch. The scale has been relocated to the instrument’s back for enhanced protection.
Overall, these setting instruments have been used fulltime by NCI to set all internal and external gages as well as to check lengths, internal diameters, pitch diameters of internal threads, bore gages, micrometers, snap and dial gages, among others.
NCI’s wide range of production takes advantage of cellular manufacturing and many four- to five-axis machining centers Machining Inserts working a long list of metals and high temperature alloys, from Rene 88, Waspaloy and various titanium alloys to many Hastelloys, Inconels and steel and stainless alloys. Because of this, the company is able to employ the Trimos horizontal setting instruments on almost any product, says Mr. Michaely.
Both machine utilization (the company’s CNC lathes and machining centers number more than 50 in the 70,000-square foot facility, recently expanded another 21,000 square feet) and quality rank high at NCI. Every day cell leaders report productivity, utilization and efficiency of every machine in the plant. The report also shows any deviations in quality over the past 24 hours. This prevents small problems from turning into major productivity or quality issues.

It’s not as simple to select the greatest carbide drill as it formerly was. How do you pick the best drill bit? You should select a drill bit that has adequate chip clearance, superior surface quality, and exact hole placements to obtain the best results. To make the best decision, be aware of the fundamentals of drill bit selection, including material, coating, geometries, kinds, sizes, and requirements.
The options might be daunting as you advance from the basic HSS carbide?twist drill to the wide variety of solid carbide drills, carbide?drills with coolant holes, and multi-function carbide drills. Carbide drills come in a variety of shapes and sizes, and they are widely used in the mining, aerospace, tool and die, and other industries. If carbide?twist drills were the only drills available, modern industry would come to a grinding halt.
It has long been accepted that drilling should only be done at slow feed rates and cutting speeds, which was originally true when using typical drills. However, the idea of drilling has evolved with the introduction of carbide drills. In reality, drilling productivity may be significantly increased and the hole-processing cost can be decreased by choosing the most appropriate carbide drill. So how can you rationally pick a carbide drill? To learn more about the specifics, continue reading the manufacturers of carbide drills.
Drill Types
First, let’s examine drills?before deciding which kind of drill to employ. The solution is based on both commercial and technological factors. The two primary categories of carbide drills?that consumers can select from are discussed here:
The carbide twist drill is easily identified by the unique helical flutes, or grooves, that span the majority of its length. Cutting fluids can enter the work area through helical flutes, which also remove chips from the hole. The term derives from the production method invented by Morse, which involved twisting the spherical drill blanks after milling the flutes.
Although cobalt alloy, solid carbide, and carbide-tipped twist drills are frequently used, modern carbide twist drills are typically built of HSS. Depending on whether the workpiece material produces long or short chips, a variety of diameters, lengths, shank types, and tip angles are available for carbide twist drills. The twist drill is the preferred drill in most situations because of its versatility.
- Carbide Drills With Coolant Holes
All aspects of customer feedback and special requirements are taken into account while designing carbide drills. This motivated us to design the best drill we could, one that could tackle almost every drilling task. Performance and low prices per generated unit are important to customers. The product is this carbide drill with an integrated cooling system. Installing an internal cooling system that clears chips from the work face will lengthen the duration between maintenance sessions. As a result, tungsten carbide drills are significantly more affordable than HSS drills. This product is a collet chuck that has been engineered to work with standard drill heads and that enables coolant to be pumped through the drill bit. The coolant can reach the hotter, more heated portion of the drill, where it is most needed, and it effectively eliminates chips from the working area.
Drills Size
To choose the right drill?for the precise size of the hole, a drill size chart and a tap size chart are frequently needed. In addition to fractional, metric, wire gauge number, and letter measurements, the drill size table also includes the standard size in other measuring systems. The size of the hole you wish to drill will determine the diameter of the drill?you select. Nowadays, the majority of drills have diameters ranging from 1 mm to 20 mm.
The size of the drill?can also be chosen based on the screws you want to use. Drill a hole that is somewhat smaller in diameter than the screw’s diameter. Use a drill?with a 3 mm diameter, for instance, if the screw you are using has a diameter of 3.5 mm. The drill and anchors should have the same size if you’re using wall anchors in addition to screws. The drill speed will also depend on the drill bit’s diameter and the material you plan to use it on. Please visit Huana Tools if you want to learn more about drills of various sizes.
Drill Materials
Typically, high-speed steel, high-speed steel with cobalt, or carbide are used to create drill bits.
The cheapest and most basic drill component, it may be used both manually and in drill presses. By periodically resharpening the drill, you can increase its longevity.
The most costly material is also the one that can last the longest. It offers the highest heat and chip resistance and has pores for coolant flow. Although carbide is more expensive than other materials, using a carbide drill often results in the lowest cost per hole since it can make more holes than cobalt and can operate 3 to 5 times quicker. The drill bit is mostly used to drill deeper holes or to work with materials that are difficult to drill.
Carbide Drill Coatings
Drilling friction is decreased by coatings. This decrease in heat enhances the flow of material out of the hole and protects the drill bit. For a quick description of the different drill point coatings, see below.
The least expensive coating, frequently used to drill work pieces made of low-carbon steel and aluminum.
Black oxide has more lubricity than brilliant finishes, is oxidation-resistant, and can have its service life extended by adding heat treatment.
The most popular alternative is titanium nitride (TiN), a very strong ceramic substance with a brilliant gold coating applied to metallic surfaces. TiN is perfect for novices and situations where cutting rougher or harder materials won’t generate a lot of heat that will pass to the tool.
- Titanium carbonitride (TiCN):?
The most lubricious of all the TiN coatings, titanium carbonitride (TiCN) has enhanced hardness and wear resistance as well as greater performance. It usually has a purple or blueish hue.
- Titanium aluminum nitride (TiAIN):?
The term titanium aluminum nitride (TiAIN) refers to a class of hard coatings that are metastable and excellent for steel and stainless steel but not for drilling aluminum. It performs better than TiN and TiCN and is great for materials used in high-temperature applications.
Overall, drills with a TiN coating are a popular choice for mild steel, drills with a TiCN coating are the best choice for cast iron, and drills with a TiAIN coating are advised for high-heat applications. If you’re not cutting challenging materials, a high-quality cobalt drill with a TiN or TiCN coating is a reasonably cheap approach to increase productivity.
The Drill Point
Among the lengths available for drill points are jobber, taper length, screw machine, mechanics, and taper shank. Shorter drills are typically better suited for tasks requiring a high degree of accuracy and precision. Additionally, they are stronger and more stiff. However, depending on the application, there are times when you’ll need to use lengthy drill bits.
The cutting head on the drill tip is angled at a drill point. The point angle or angle created at the drill tip depends on the substance it will be working with. Sharper angles are needed for softer materials and greater angles for harder ones. Wandering, chatter, hole form, and wear rate are all influenced by the proper point angle for the material’s hardness.
Carbide drills typically come in three different angles: 90 degrees, 118 degrees, and 135 degrees. Only use 90-degree drills on soft materials, like plastic and aluminum, as they quickly get dull. You may always use a protractor to record the angles on paper, as we have done here, if you are unsure of what you have. The most typical angle for consumer bits is 118 degrees. Almost every material you work with, including steel, aluminum, wood, stainless steel, brass, cast iron, and plastic, is acceptable for them. These carbide drills could wander on tougher substances like steel and stainless steel, necessitating the use of a center punch to hold them in place during the initial cut.
135-degree drills work well for hard materials like steel and stainless steel. The shallow angle makes it possible for the drill to cut into the material without fast becoming dull, but it also causes the bit to desire to wander, necessitating the use of a center punch.
Cutting Length
The length of the drill hole is determined by the drill diameter, which is the diameter of the cut. Special cutting lengths can improve cutting performance. Tools and machinery will have a longer lifespan. As a result, the drills may get consistent dimensional precision and superior surface quality, making them appropriate for processing systems with exceptional stiffness. We provide 3D and 5D drills, which stand for 3 Carbide Drilling Inserts times and 5 times the cutting diameter, respectively. Carbide 3D and 5D type drills with strong cutting resistance and a stiff blade tip. Use on a variety of materials is advised. uses a coating that has great toughness and wear resistance to assist extend the life of the tool.
Flute Design Features
Flutes have a variety of uses, from inexpensive removal to a path for cutting fluid to contact the cutting surfaces. The drill’s body has grooves called flutes that allow the drill to pierce the surface you are working on. There are many varieties of the flute, but these are the ones that are most popular right now:
- Standard flute design:The most often used flute design is round in cross-section.
- Straight flute:It is appropriate for usage when TNMG Insert the drill’s stiffness is more important than chip evacuation. Additionally, it works best for short-chip materials, when spinning work pieces are used rather of drilling.
- The parabolic flute design:It?has numerous advantageous characteristics, including a low peck cycle, a high feed rate, a smooth, inexpensive evacuation, and quick cycle times. It functions via a quick spiral and open geometry.
You don’t need to be concerned about where to find the design you want. You simply need to say what you want using Huana tools modification for designs, and you’ll have it!
Can carbide drill bits be sharpened?
Even the highest-quality drill bits will eventually become worn out, at which time you must choose between sharpening or replacing them. Carbide drill bits are expensive, therefore it’s probably worthwhile to sharpen them. Any sharpening won’t work on your carbide drill bits, though. You must use the proper equipment for the task, in this case a diamond-surface grinding wheel.
It could be more economical to pay a professional to perform it for you if you don’t have access to a grinding wheel. Therefore, even while you can sharpen carbide drill bits yourself, doing so takes specialized equipment, and doing it well may require considerable expertise.
Conclusion
It is essential to the success of any project or application to select the appropriate drill bit for the work at hand. However, in order to save yourself time, money, and effort when choosing a drill bit, it is important to have a full understanding of the elements that should be considered. If you make the proper pick, you may extend the life of your drill bits in a number of different ways, including matching the suitable bit to the substrate material, finding the perfect fit for the depth and diameter of the hole, or even the amount of work that has to be done. This, in turn, serves to boost productivity since it enables you to do more with each drill bit that you use.

Metal machining and specifically milling are widespread in modern prototyping techniques. Prototype manufacturers tend to maximize their equipment capabilities in regards to technology. One of the methods that have become popular in recent years is helical milling. Let’s try to clear up what helical milling is about, its pros and cons and how you can use this knowledge while designing your prototype to lower its manufacturing costs.
What Is Helical Milling?
Helical milling is an alternative hole-making process. This process involves an endmill that follows a helical trajectory to achieve a high-quality bore. It offers a lot of advantages compared to conventional drilling and it can downright replace boring machines, which is always advantageous for prototyping shops as they really want to avoid buying lots of equipment.? (Ha, not saying that they are dull, they are quite sharp actually, wait… they are boring and sharp at the same time. This wordplay is killing me). Helical milling can be used to create bores of practically any form, the cutting force is lower, tool wear as well and the achievable quality can be quite high.
Why not drilling?
The main alternative to helical milling is conventional drilling. It is a very widespread method of making holes. Statistically, drilling takes up to 25% of cycle time and 33% of the total number of machining operations when manufacturing a metal part. But why should you consider milling? Despite the fact that obviously, the kinematics are much simpler, drilling has a range of cons that justify using a more complicated milling technique.
For example, Drilling speed differs with the diameter. It is highest at its outer point and is practically zero in the center of the drill ( where the axis is). It means that the machining process near the revolution axis is not actually cutting but plastic deformation. This increases the thrust force of the tool and the tool wears drastically.
Because of the axial thrust force, the drill, especially a worn one, will bend a thin layer of metal as it exits the stock. The resulting leftover material protrudes around the hole and needs to be removed manually. Using a mill instead drastically lowers the leftover material.
Drilling provides awful chip removal conditions.?The processed material can only be removed through the drill flutes. Chip removal influences the surface finish of the hole and the cutting temperature. As the bits of metal move from the cutting zone through the flutes to the surface, they scrape the sides of the hole and lower the surface finish.? It has been proven that the chips carry up to 80% of cutting warmth, so removal problems increase the temperature of the drill. It wears down faster because of that. In order to increase chip removal rate, operators use discrete drilling methods. The drill processes a part of the whole length after which it is removed. This is a good strategy but the drilling time increases.
As you can see, drilling has some significant drawbacks so, in the tendency to increase machining efficiency and thus the efficiency of prototyping shops, manufacturers employ helical milling
Some helical milling specifics
Let’s review some of the processes that happen in helical milling.
Firstly, the end mill moves along a helical path. It means that the milling center must combine the vertical z-axis movement and the horizontal x-y axis. This makes the NC program very complex to write manually, however, a lot of CAM-systems have adopted helical milling as one of the strategies.
The geometry of the chip consists of two zones: the blue one that is created by the side of the end-mill and the red zone that is created by the face of the mill. It has been proved that the ratio between the two zones is determined only by the tool and bore diameters.
With the increase of the tool diameter, increases the blue zone. It provides worse milling in regards to vibration as the blue chip is discontinuous, unlike the red one. So, the WCMT Insert surface finish will be worse.? In addition, with the increase of the volume removed by the side of the mill, radial cutting forces grow (red Fr at the picture) and they bend the tool inside of the hole, so the tolerance decreases.?The negative effect is decreased to some degree by the fact that larger tools have more rigidity.
If the tool is smaller, the red zone prevails, so the radial force is small, as well as vibration, however, the decrease in tool diameter is limited by the system rigidity.
I’d say that using a larger tool at first is better and changing it to a smaller one for a final cut with low depth and feed will result in a great surface finish.
Reasons to use helical milling
As you can see, helical milling is a promising process that offers a number of Indexable Inserts advantages.
You can achieve any diameter with better precision and surface quality without changing the tool.? If you’ve ever drilled a whole bigger than 35 mm, you’ll know that doing it with only one drill is a bad decision. It’s usually done with a range of smaller drills, For example, the initial whole will be 10 mm, then it will be drilled to 20 mm with a bigger drill and only then to 35 mm. Afterward, if you need more precision or surface finish, you ream or countersink the hole. That’s like 4-6 tool changes to get a whole did. Well, with helical milling you’ll just need to use one endmill to cut out the hole and then use a smaller feed to achieve desired tolerance and quality. You can achieve up to IT7 with Ra 1,25 without changing the tools.
You have a lower cutting temperature and better chip removal. The endmill does not take up the whole space of the bore. That’s the main advantage. You don’t have to extract the tool after plunging every 30 mm or so. Just spray the coolant into the hole and it will delete the chip and lower the temperature of the machining.
You can predict tool wear and make trajectory modifications. One of the main problems in drilling is that when the drill is worn, you can mostly see it once it is completely broken when machining hard materials, it can even get stuck in the bore. With helical milling, you are basically just milling. So, you can predict tool wear by using standard calculation methods or using tool life specified by the manufacturer. You can even take those changes into account during the process. So, you can change the trajectory a bit to preserve the diameter dimension. You can’t really do that with drilling though. Oh, by the way, the tool life is determined by the face wear of the tool (red zone chip).
Conclusions
Of course, helical milling is an innovative process and it has its cons. For example, its chip removal rate isn’t as fast and its parameters are not that well researched yet. However, this technique lowers the number of setups, machining, and tooling, while retaining the quality of the bores. That is a?considerable advantage for prototyping manufacturers who want to minimize the amount of tooling and equipment required.
