Machining Materials and Selection of PCD Tools

PCD cutters have become an indispensable and necessary means in modern machining. This is mainly because it has three aspects: high-speed cutting, high-stability processing, ultra-precision mirror processing, dry cutting, and cleaning processing. Let's take a look at the processing materials of PCD cutters and what aspects need to be considered in selection?

Ⅰ. The processing material of PCD cutter

1. Difficult-to-machine non-ferrous metals and their alloys

When processing non-ferrous metals such as copper, zinc, aluminum and their alloys, sintered hard alloys, titanium alloys, and babbitt alloys, the materials are easy to adhere to the tool, which is difficult to process. PCD cutter can effectively prevent the metal and the tool from bonding, and the tool life long.

For titanium alloys, copper alloys, tungsten carbide (Co < 16% and Co > 16%), aluminum alloys (4-8%Si and 9-13%Si), high silicon aluminum alloys (>13%Si) , CDW010 grades of PCD cutters can be applied, for alloy materials with higher wear resistance requirements, coarse-grained and mixed-grained PCD material tools CDW025 and CDW302 can be used.

2. Difficult to process non-metallic materials

When processing glass fiber reinforced plastics, filler materials, hard carbon fiber/epoxy resin composite materials, ceramics, and wood, the tool wear is serious and it is difficult to process. PCD cutters have high hardness, good wear resistance, and high processing efficiency. Commonly used PCD materials are CDW010, CDW025 and CDW302.

Ⅱ. Factors to consider in the selection of PCD cutters

The main considerations for the selection of PCD cutters: surface accuracy, shape accuracy, dimensional accuracy, tool deformation, shortened work cycle, shortened downtime, increased tool life, hard materials, tool cost, reduced investment and other factors.

In a word, PCD cutter is a tool made of superhard material PCD (polycrystalline diamond) and tool matrix through a special process. Mainly used for processing wear-resistant non-ferrous metals and their alloys and non-metallic materials. At present, PCD cutters have been widely used in non-ferrous metal processing, automobile, motorcycle, aerospace, wood, carbon fiber and alloy parts processing.
