Iscar coating technology stands out in the market competition

the preparation of the substrate, coating and blade of cutting tools plays a key role in efficient machining, often related to the success or failure of metal cutting processes. These factors, together with the embedded chip breaker and tool tip, determine the adaptability of the cutting tool to a specific workpiece or a specific purpose. The combination of these parameters can ensure long machining life and good economy of the tool. When designing blades to meet increasingly demanding machining applications, the newly developed substrate material, containing tungsten, is the substrate, coating and spare parts researched and developed by cutting tool manufacturers to meet the new challenges of workpieces

the hardness and toughness of tungsten carbide tools can cope with a wide range of cutting parameters. Cutting tool manufacturers can manufacture base materials by changing the size of tungsten particles in the range of 1 to 5 microns

with finer particles (sub micro particles), the tool is more wear-resistant. On the contrary, larger particles make the tool more ductile. Fine grained base materials are mainly used for cutting aerospace industrial materials. Waste foam granulators are added to the production range of Enterprises above foam granulators, such as titanium, Inconel (Inconel) and superalloy blades

in addition to changing the particle size of these tools, tool manufacturers can also arbitrarily change the content of cobalt in the base material. Cobalt is used as a binder to keep tungsten carbide particles bonded together. Increasing the cobalt content from the usual 6% to 12% can improve the toughness and enable the tool manufacturer to adjust the composition of the tool to meet the requirements of any application if there is a torque value, whether it needs toughness or wear resistance

tool manufacturers can also improve the performance of base materials by adding a concentrated cobalt layer to the tool surface, or by selectively adding other kinds of alloy elements, such as titanium carbide (TIC), tantalum carbide (TAC), vanadium carbide (VC) and niobium carbide (NBC), to the composition of tungsten carbide. The concentrated cobalt layer greatly improves the strength of the blade and improves the performance of rough cutting and intermittent cutting. When the workshop selects the base material to match the workpiece material. At present, some domestic material enterprises have been comparable to international and processing requirements in terms of material technology and performance quality, it should be noted that the five other characteristics of the base material, fracture toughness, transverse fracture strength, compressive strength, hardness and thermal shock resistance, are also very important

cutting tool manufacturer iscar metalsinc Claims that the development of coatings in recent years, due to the expensive chemical vapor deposition coated tools, has led to the growth of the demand for physical vapor deposition coated tools. The thickness of chemical vapor deposition coatings ranges from 5 to 15 microns, while the thickness of physical vapor deposition coatings ranges from 2 to 6 microns. When chemical vapor deposition is added to the top of the substrate material, tensile stress is generated, while physical vapor deposition coating increases compressive stress on the substrate. Iscar said that the difference between tensile stress and compressive stress affects the performance of the blade in continuous cutting and intermittent cutting. In the coating process, the development of new alloy elements is also helpful to bond the coating and improve the performance of the coating

iscar's latest generation of coating technology, which is called Tec in the market, has modified chemical vapor deposition and physical vapor deposition, and even combined the two to produce cutting tools to better meet special applications. For steel, iscar Tec brand provides chemical vapor deposition TiCN coating at moderate temperature, including A1203 coating thickness, which is designed to improve wear resistance in high-speed cutting, and has good thermal stability, spalling resistance and plastic deformation resistance

on the contrary, for cast iron, iscar developed an AlTiN physical vapor deposition coating, called al Tec, which has high aluminum content and good heat resistance. The company said that its performance is superior under low to medium cutting speed and unstable processing conditions. Another coating iscar uses for various grades of cast iron is do tec. It is to add a TiAlN physical vapor deposition coating to a medium temperature chemical vapor deposition A1203 coating. This combination brings many benefits to the workshop, such as high wear resistance and spalling resistance when medium to high speed cutting is used

for the future, iscar said that he expected to see the climax of advanced plasma coating and diamond-like carbon coating used in mass production. The company also said that another growing innovation in coating is the single-layer multifunctional coating that will replace the traditional, thick multi-layer coating. According to iscar, the single-layer multifunctional coating is easy to be designed to be suitable for various tribological and mechanical properties. Recently, iscar pointed out that the growing research of nanotechnology is promoting the mass production of nano coating technology, which has good toughness, hardness, oxidation resistance and thermal stability

preparation of cutting edge

in many examples, it is shown that the preparation of cutting edge (honing) may affect the success or failure of machining, and appropriate honing parameters should be specified in various applications. For example, Gao is a brand-new green and environmental protection product. High speed finishing steel and rough machining require completely different blade preparations

generally, for continuous turning and milling of most steel and cast iron, basic honing is enough. However, for heavy intermittent cutting, heavy honing or t-edge with blade is required

on the contrary, for processing stainless steel or superalloy, because these materials tend to accumulate materials on the blade, the blade requires small grindstones and sharp blades. Similarly, for cutting aluminum, sharp blades must also be used
