As with any other tool, the life of the stone carving knife varies, depending on the material being machined, the feed rate selected and the cutting speed, and the geometry of the workpiece. In general, the life of diamond-coated diamond tools is 10-20 times that of uncoated carbide cutting tools, and in some cases may even be longer. In this way, you can use a tool to complete almost any processing tasks, without tool wear and tool change, to avoid the processing of interruption and re-calibration, which may achieve unattended processing. In the processing of composite materials, it is also possible to obtain a longer tool life

    The peeling of diamond coatings can prevent coating peeling is a serious problem with diamond-coated tools and is a common problem (especially when processing materials such as carbon fibers) that can cause tool life to be unpredictable. In the late 1990s, the interface chemistry was identified as an important factor affecting the adhesion of diamond coatings. It is possible to reduce or eliminate the peeling of the diamond coating and to achieve a stable wear pattern by selecting the appropriate chemical properties of the cemented carbide, using appropriate pretreatment techniques and reasonable deposition reaction conditions. Under the microscope to observe the normal wear of the diamond coating tool, you can find that the diamond was stably worn until the carbide base, without the occurrence of chipping or peeling.
