Customized Size PCD Cutting Tool Blanks For Cutting Ceramic Products

1. Product Decription of PCD Blank

PCD Blank has different advantages such as high abrasive resistance, low friction coefficient, high rigidity, high thermal conductivity, low heat expansion coefficient, good strength and stiffness.

Its hardness can reach up to 8000 HV, which is 80 to 120 times more than tungsten carbide.PCD has the thermal conductivity from 1.5 to 9 times higher than tungsten carbide. It is also than that of PCBN and copper. Its thermal conductivity approaches 700 W/mK. The PCD blank has a possibility to transfer heat fast.

The friction coefficient of PCD is smaller than that of tungsten carbide. It is only 0.1~0.3 in regard to 0.4~1.0 that tungsten carbide has . The PCD cutting tool has small cutting force.

The heat expansion coefficient of PCD is from 0.9×10^-6 to 1.18×10^-6 (one fifth that of tungsten carbide). Its cutting tool has a very small thermal deformation and high processing accuracy.

The attraction between the PCD and the materials like nonferrous metal and nonmetal materials, is very small. This results that the cuttings won’t attach to the tool during processing.

Quality Control Of PCD Blanks/PCD Discs:

We Guarantee Every Single PCS Will Be Strictly Inspected By Ultrasonically Scanned Before Delivery.

For The Problem Like Unflatness, Internal Defects, Tiny Scratches, Chips, Poor Tolerance And Size Etc, We All Sort Out And Label Them As Rejection. The Rejections Are Not Allowed To Be Sold Out !

Meanwhile, Each Batch Of PCD Will Be Taken By Random For 10% To Make The Testing Of Abrasive Ratio. Only The PCD Discs Are Tested To Meet Our Quality Inspection Standard, We Will Tag It As Standard Products For Sales.

5. Various PCD Cutting Tools For Reference

Zhengzhou Halnn Superhard Materials Co., Ltd is a high-tech enterprise specializing in the production of ultra-hardened tools, and the leader of professional hard material processing tools in China and the first to research new cutting tools specific for gray cast iron, kinds of wear-resistant steel/cast steel, hardened steel materials.

The predecessor of Halnn Superhard Material Co.,Ltd is Henan Superhard Material Institute which is the earliest to make research on processing the brittle and hard materials with cubic boron nitride tools and High-Grade Diamond Tools. As the pioneer of Industry tools in China, Halnn adhere to the initial business philosophy of "Not seeking large and complete, only insist high-precision and professional". With more than 10 years experience, Halnn has researched one by one new materials grade, new technology and become the most famous cutting tools brand in superhard cutting tools industry.
