What materials are used for carbon fiber milling cutter coating?

There are many options for carbon fiber milling cutter coating materials, which are designed to improve the wear resistance, finish and service life of the tool. The following are some common carbon fiber milling cutter coating materials summarized by Zhongyeda editor:

Diamond coating:

Diamond is the hardest substance in nature, so diamond coating can significantly improve the wear resistance and cutting performance of the milling cutter.

Diamond-coated tools can maintain the sharpness of the blade, reduce cutting force and cutting temperature when processing carbon fiber composite materials, thereby reducing tool wear and workpiece deformation.

In addition, diamond coating can also improve the finish of the machined surface, reduce burrs and delamination.

Diamond-like carbon (DLC) coating:

DLC coating is a coating material with excellent wear resistance and low friction coefficient.

It can significantly improve the wear resistance and service life of the milling cutter, while reducing friction and cutting temperature during cutting.

DLC coating also has the characteristics of not easy to stick to the tool, which can reduce the built-up edge and sticking of chips during cutting, thereby improving processing quality and efficiency.

Cubic boron nitride (CBN) coating: CBN is a material with high hardness, high thermal stability and good wear resistance. CBN coated tools perform well in machining difficult-to-machine materials such as high-temperature alloys, titanium alloys and carbon fiber composites. It can maintain the sharpness of the blade, reduce cutting force and cutting temperature, and improve machining efficiency and workpiece quality. 

Carbide coating: Carbide is a composite material composed of high-hardness carbides (such as tungsten carbide, titanium carbide, etc.) and metal binders (such as cobalt, nickel, etc.). Carbide coated tools have excellent wear resistance and impact resistance and are suitable for machining materials of various hardness. In carbon fiber processing, carbide coated tools can maintain good cutting performance and long service life. In summary, there are many options for coating materials for carbon fiber milling cutters, including diamond coating, DLC coating, CBN coating and carbide coating. These coating materials have their own characteristics and can significantly improve the wear resistance, finish and service life of the milling cutter. When selecting coating materials, it is necessary to consider the specific processing requirements and workpiece materials comprehensively.
