Polycrystalline diamond cutting tool design

PCD cutting tool geometry parameters depend on the workpiece position, tool materials and  Diamond blade  and other specific processing conditions. Since PCD tool used for finishing the workpiece, the cutting thickness is small (and sometimes equal to the radius of the tool cutting edge), are micro-cutting, so flank face angle and the subsequent processing quality had a significant effect, the smaller the back angle, higher flank PCD tool for improving the quality of the processing quality can play an important role.
PCD composite sheet with Arbor connection methods include mechanical clamping, welding,  cubic boron nitride of ways, their characteristics and applications are shown in Table 2.
Table 2 PCD composite sheet Arbor connection with the characteristics and applications
Connection - Features - Applications
Mechanical clamping - from standard cutter body and can be made into various collections  cutting tools blade angle can be changed with a quick and easy regrinding advantages - small machine tools
Welded - compact, easy to make, can be made small tools - special tools or difficult to machine clip tool for small machine tools
Machine folder Welding - Welding in knife blade head, you can use standard shank for easy sharpening and adjusting head position - automatic machine tools, CNC machine tools
Indexable - compact, reliable clamping, without re-grinding and welding, can save auxiliary time, improve tool life - ordinary general machine
