Now we are able to provide the polycrystalline diamond PCD blank of diameter 64mm, which can be used by cutting tool makers for making cutting tools to process wood, plastic and metal materials.
With the increased PCD blank diameter to 64mm, the utilization rate of PCD materials has been greatly improved while cutting the PCD disc to designed segments and shapes for the cutting tools.

Applications of Cutting Tools with PCD tipped
(1) PCD tool for ferrous metal and non-metal processing
Generally speaking, we know that diamond PCD tools can process non-ferrous metals such as copper, aluminum, magnesium, and copper. In addition, diamond PCD tools are also suitable for processing non-metallic materials such as composite materials graphite, carbon fiber and plastics.

(2) Machining graphite with PCD milling cutter
While processing graphite electrodes, graphite hot bending dies, solar graphite parts, other graphite spare parts, the ordinary tools are not only difficult to process graphite, but also easy to wear and tear. Large-scale use is not only costly, but also low efficiency.
With coated PCD tools, its service life is 10-20 times that of uncoated carbide tools, and in some cases it may even be longer, which improves efficiency and reduces costs.

It is not easy to process composite materials. The difficulty of processing lies in the high brittleness of the material, high fiber composite strength, and poor uniformity. If the cutting tool used is not sharp or the cutting feed is large, it will cause the dense fiber to be difficult to cut off.
(3) Processing carbon fiber
Carbon fiber composite materials are difficult-to-cut materials, which are brittle, high in strength, high in carbon fiber hardness, and poor in thermal conductivity.
In addition, carbon fiber composite materials are anisotropic and have low interlayer strength. Defects such as delamination and tearing are prone to occur under the action of cutting force during cutting.
processing carbon fiber
Since coolant cannot be used in the high hardness cutting of carbon fiber, the heat is transferred to the cutting tool, which makes the tool wear fast, the tool durability is low, and the tool life is shortened, so it is easy to wear when using ordinary tools.
According to the processing characteristics of composite materials, diamond PCD cutting tools have the characteristics of high hardness, high wear resistance, and high thermal conductivity and are sharp, avoiding processing interruption and recalibration, reducing processing time, improving efficiency, long tool life, and reducing costs.
It is widely known and it should be noted that diamond tools are not suitable for processing steel materials, because diamond has a strong chemical affinity with iron. At high temperatures, iron atoms easily interact with carbon atoms to convert them into graphite structures, and the tools are easily damaged. Therefore, PCD cutting tools are suitable for processing non-metallic materials and non-ferrous metal materials and their alloys.
