PCD Inserts

Polycrystalline diamond inserts, often referred to as PCD inserts, are made from synthetic diamond particles sintered together under high pressure and temperature. This process creates a cutting tool that is can withstand extreme conditions and machine the hardest materials such as non-ferrous metals, titanium- & aluminium-based alloys, composites, plastics, glass, ceramics and much more.

Benefits of Using PCD Inserts

Versatility

PCD inserts can be used across a wide range of materials and offer machining complex workpieces with a single cutter. This versatility makes them suitable for various industries and applications.

Superior Surface Finish

PCD inserts can deliver exceptional surface finishes and dimensional accuracy equal to that when grinding. They are known for producing smooth, high-quality surfaces, reducing the need for secondary finishing processes.

Cost-Effective

While PCD inserts may have a higher initial cost, their extended lifespan and reduced downtime contribute to significant cost savings over time. The return on investment becomes evident as production cycles become more efficient and reliable.

Polycrystalline diamond (PCD) inserts are used in various machining applications, particularly for materials that are challenging to cut, such as non-ferrous metals and composites. We at WENZA offer various PCD grades that are differentiated based on the composition and properties of the diamond material used. For more information refer to the table below.
Please note that PCD inserts by WENZA are usually manufactured with chamfer F0000N. Custom chamfers can be produced on request.
