As a type of superhard cutting tool, the application proportion of PCD cutting tools in the field of machining has been increasing year by year, which is closely related to the continuous increase in the processing volume of difficult to machine materials and non-ferrous metal materials.

PCD tool is mainly used for cutting and processing non-ferrous metals such as aluminum alloys, copper alloys, as well as non-metallic materials such as fiber plastics, hard rubber, graphite materials, resin polymer materials, etc.

At present, more and more customers have increasing requirements for the surface quality of processed workpieces. Compared to general hard alloy tools, PCD tools can achieve higher cutting speeds and longer tool life, while also maintaining the surface quality and dimensional accuracy of the processed workpiece for a long time.

When customers use milling cutters to process pure copper plates, due to the relatively soft material of the workpiece being processed and the requirement for surface roughness Ra value to reach 0.2μm during processing , this poses a significant challenge for machining tools, as everyone knows that soft materials are less likely to achieve lower roughness.

LINKUT adopts a curved polishing edge design for the cutting edge of PCD milling insert, which makes the polishing edge PCD tool no longer too smooth. This can effectively reduce cutting resistance, reduce cutting noise, and achieve a Ra value of 0.058μm on the machining surface . In addition, on the basis of meeting the processing requirements, the tool life is also relatively extended, directly achieving the effect of reducing the cost of single piece processing. The  customer was very satisfied and received good feedback.
