Polycrystalline diamond (PCD) tool is made by welding PCD composite to cemented carbide or steel tool body. Because PCD composite combines the high hardness, 

wear resistance, low friction coefficient and strength of single crystal diamond with the high bending strength of tungsten carbide cemented 

carbide, the tungsten carbide cemented carbide layer of the composite provides mechanical support for the diamond layer and increases its bending strength. At the 

same time, the cemented carbide layer is easy to weld, making it easy to make finished tools.

The structural forms of PCD tools include: indexable inserts with pcd tip, PCD milling cutter, PCD reamer, PCD drill bit, PCD grooving cutter and non-standard PCD tools.

The selection for Diamond Tools:

Main considerations for PCD Tool Selection: surface accuracy, shape accuracy, dimensional accuracy, tool deformation, shortened working cycle, shortened downtime, 

increased tool life, hard materials, tool cost, reduced investment and others.

The Cutting parameters for diamond CNC turning tools:

1)  Cutting speed VC

PCD tools can cut at very high spindle speed, such as turning silicon aluminum alloy at a speed of 1000m / min and high-speed milling at 3000m / min;

2) Feed rate fr

PCD cutting tools should select appropriate feed rate according to different machining conditions. Excessive feed rate will affect surface roughness, and too small feed rate 

will increase cutting temperature;

3) Cutting depth AP

PCD cutting tools should choose the appropriate cutting depth according to different machining processes. Excessive cutting depth will affect the tool life.

LINKUT diamond (PCD) tools are mainly used to process non-ferrous metals such as non-ferrous metals, which can grind a very sharp edge and get a better machining surface. 

PCD indexable tools are also the first choice for processing new non-metallic materials and can cut high hardness products such as cemented carbide and industrial ceramics.
