Incredibly resilient to wear, a PCD (polycrystalline diamond) lathe insert is a cutting tool formed through incredibly high temperatures and pressures, fusing together diamond powder with a cobalt or other binder. Crafted for optimum toughness, these inserts are ideal for machining particularly hard materials on lathes or other machine tools.
PCD inserts can be employed to cut metals such as aluminum, brass, bronze, cast iron, steel, and titanium with ease; these inserts are also quite capable when it comes to machining non-ferrous metals, composites, plastics, and other non-metallic materials.
Different shapes including squares, rectangles, circles, and triangles are offered in PCD inserts. Grades within the PCD range are based on the size and form of the diamond particles, with higher grades defined by more refined diamond particles that bring greater wear resistance.
A screw or alternative securing device is used to fasten the PCD insert to the lathe tool holder. This ensures that the insert can withstand the force of the rotating tool like a drill bit or end mill, and can safely be machined.
The remarkable resilience of PCD inserts renders them applicable for numerous machining techniques, such as turning, boring, milling, drilling, grinding, and polishing.
Different companies offer PCD inserts, from the well-known Kennametal and Sandvik, to Mitsubishi and Sumitomo.
When compared to other lathe inserts, PCD inserts usually come with a higher price tag. But they possess a plethora of perks, such as an extended operation life, a faster cutting pace, and an improved surface finish.
