Polycrystaline Diamond Inserts Overview
What is a PCD Insert?
A PCD insert refers to a cutting tool insert made with polycrystalline diamond (PCD). It is produced by firmly bonding or sintering a diamond layer onto a carbide substrate, combining extreme hardness and wear resistance with strength and stability.
Polycrystalline diamond (PCD) Overview
Polycrystalline diamond (PCD) is a highly durable material known for its long cutting lifespan, ability to work at high cutting speeds, and outstanding performance in processing non-ferrous materials like aluminum and composites.
PCD Tipped Inserts Applications
PCD tipped inserts are widely used for high-efficiency machining of aluminum alloys, copper alloys, carbon fiber, composites, and other non-ferrous materials. Compared with conventional carbide inserts, PCD inserts offer significantly longer tool life, higher machining efficiency, and superior surface quality, making them an ideal choice for industries such as automotive, aerospace, electronics, and precision manufacturing.
Advantages Of Using PCD Inserts
PCD tools are highly wear-resistant and fairly durable for cutting through the toughest materials. Carbide bases add strength and stability to the structure, and PCD tools are ideal for precision cutting. The fine finish obtained by PCD polishing is often referred to as a “diamond” finish. Because PCD tools are so durable, they retain sharp edges much longer than traditional tools and have an excellent lifespan while maintaining high cutting and polishing accuracy. They can also be used to cut material at high speeds, increasing removal rates and reducing the time required to complete machining tasks.
When it comes to machining non-ferrous and non-metal materials, PCD turning inserts is the great choice for the following material application:
