PCD (Polycrystalline Diamond) is a synthesized, extremely tough, intergroup mass of randomly orientated diamond particles in a metal matrix. It is produced by sintering together selected diamond particles at high pressure and temperature.
Features
PCD PCBN blanks - Superior imported materials.
The PCD CBN cutting tools have the advantages of high abrasive resistance, processing precision, good thermal conductivity and long service life.
With sharp cutting edge, sharp, high precision.
The body uses high quality tungsten carbide or steel.
Machines imported from UK, Germany, Japan.
PCD Chipbreaker Insert Advantages
PCD Insert with chip breaker has higher efficiency, and long service life.
It can remove the chip of the hole processing more smoothly, to meet the high efficiency machining requirements for surfaces.
It can prevent tool breakage, damage, and ward off the workpiece scrapped caused by unsmooth chip removal.
It can effectively deal with the surface problems of the workpiece in the automatic production lines, such as burrs, chips, and scratches.
Application
PCD may be cost effectively employed to machine the following broad range of materials:
Non-ferrous metals and alloys: including aluminum, copper, bronze, brass, green tungsten carbide, precious metals and MMC's.
Non-metallic materials: including ceramics, reinforced plastics, hard rubber, chipboard, MDF's and other fibreboards, etc.

Frequently Asked Questions (FAQ)
What is PCD and why is it used for cutting tools?
PCD (Polycrystalline Diamond) is an extremely tough, synthesized diamond material. It is used for cutting tools because it provides outstanding abrasive resistance, superb processing precision, and an exceptionally long service life compared to traditional carbide tools.
What are the benefits of using a PCD insert with a chipbreaker?
The integrated chipbreaker design helps remove chips more smoothly during turning. This prevents chip build-up, reduces the risk of tool breakage, protects the workpiece surface from scratches, and enhances efficiency on automated production lines.
Which materials are suitable for machining with PCD tools?
PCD tools are highly recommended for non-ferrous metals and alloys (such as aluminum and copper) as well as non-metallic materials (including ceramics, reinforced plastics, hard rubber, chipboard, and MDF).
Can PCD inserts be used to cut steel or other ferrous metals?
PCD is generally not recommended for machining ferrous metals (like steel or cast iron) because the carbon in the diamond chemically reacts with the iron at high temperatures, causing rapid tool wear. For ferrous materials, PCBN (Polycrystalline Cubic Boron Nitride) is preferred.
How does the silicon content in aluminum affect the cutting speed of PCD tools?
Higher silicon content increases the abrasiveness of the aluminum alloy. For low-silicon aluminum (5-8% Si), cutting speeds can go up to 1600 m/min. For high-silicon aluminum (14-18% Si), recommended cutting speeds are reduced (160 to 800 m/min) to optimize tool life and quality.
