Tungsten steel milling cutters and coated milling cutters are both common metal processing tools. Since they are both milling cutters, what are the specific differences between them? In our actual working conditions, can these cutters be treated universally? The answers to these questions will be answered by us. As a professional milling cutter manufacturer, ZXGLW would like to emphasize here that there are actually differences between tungsten steel milling cutters and coated milling cutters. Although they both have good performance, they have different focuses in different aspects.
Tungsten steel milling cutter: The material of tungsten steel milling cutter is mainly hard materials such as tungsten carbide and cobalt, so it can also be called cemented carbide milling cutter. The characteristics of the material give this tool high hardness, high strength and good wear resistance. The hardness is generally between HRA89-93. It can maintain stable performance under high-speed cutting and heavy-load cutting conditions, and cut materials of various hardness, such as alloy steel and stainless steel with higher hardness.
Coated milling cutter: The base material of the coated milling cutter can be high-speed steel or cemented carbide, and the coating is a layer of special material coated on the surface of the base, such as titanium nitride, TiAlN aluminum titanium nitride, TiCN titanium carbonitride, etc. The role of these coatings is to improve the hardness, wear resistance, oxidation resistance and reduce the friction coefficient of the tool.
Tungsten steel milling cutter: High hardness and wear resistance are the basis for tungsten steel milling cutters to cut continuously for a long time, so they are more suitable for processing materials with higher hardness. Tungsten steel has a high thermal conductivity, which can dissipate heat well during cutting and reduce thermal deformation of the tool. However, the toughness of tungsten steel milling cutters is relatively low, and their ability to withstand impact loads is limited.
Coated milling cutter: The coating can reduce the friction coefficient between the tool and the workpiece, reduce the generation of cutting force and cutting heat, and improve processing efficiency and surface quality. Different coatings have different performance characteristics, and the base material of the coated milling cutter can be selected according to different processing requirements, and the main properties such as toughness and wear resistance will therefore have differences.
Tungsten steel milling cutter: Tungsten steel milling cutter is widely used in mold manufacturing, aerospace, automobile manufacturing and other fields. It is more advantageous when the material hardness is high and the required processing precision is high.
Coated milling cutter: Coated milling cutter is suitable for cutting various materials, including steel, cast iron, aluminum alloy, copper alloy, etc., and has a wide range of applications in high-speed cutting, dry cutting and precision machining.
