PCD/PCBN Cutting Tool Blanks 

PCD blanks for cutting tools is sintered by ultra-high pressure high temperature with micro-diamond particles and carbide alloy, consist of polycrystalline diamond and carbide alloy substrate. Its hardness and wear resistance is as well as the nature diamond and the toughness as same as carbide alloy. The workpiece processed by this cutting tools has finish surface and no need being ground. It is an ideal tools material for its long life and high efficiency.

KO polycrystalline diamond cutting tool blank is given widely varying physical characteristics to adapt them to specific application. This enables you to select a diamond abrasives precisely suited to your needs.

Advantages Of KO PCD Cutting Tool Blanks:
KO PCD/PCBN cutting tool blanks are produced by sintering selected Diamond particles at high pressure and high temperature, and Consist of diamond layer
And tungsten carbide substrate.

PCD Blanks provide the hardness, abrasion resistance and Thermal
Conductivity of natural diamond, combined with the Toughness of tungsten carbide. The work piece processed by PCD has good surface finish and no need being ground. It is An ideal tool material for its long life and high efficiency.
@ Long life tool
@ Uniform surface finish
@ Reduces machine down time
@ Highly improved workpiece quality and excellent dimensional
Control
@ Increase productivity
@ High material removal rate
@ Lower cost per piece
The tool life of a PCD cutting edge is usually 50 to 250 times.

 

PCBN Cutting Tool Blanks used for CBN inserts
Features:

Application:
The PCBN blank is mainly userd for the machining of high hardness and hard processed ferros materials such as
Hardened Steels
Pearlitic gray cast iron
High temperature alloy
High-speed steel,
Hard facing alloys,
Ni-Cr alloy
Powder metallurgy metals

Advantages:
Higher material removal rate
Decrease of cycle time
Consistent surface finish
Longer tool life
Doing without refrigerant
Lower machining cost
It actually realized replacing the grinding by the turning, which greatly enhanced work efficiency and reduced effectively production cost.
