FAQ: What You Want to Know about Diamond Tooling

What is PCD?

Poly­crys­talline Dia­mond, PCD, is the hard­est known mate­r­i­al and has many advan­tages in man­u­fac­tur­ing. PCD is a syn­thet­ic dia­mond pro­duced by sin­ter­ing togeth­er micron-sized pieces of dia­mond pow­der with a met­al binder, typ­i­cal­ly cobalt, under extreme pres­sure and temperatures.

Why is diamond a good material for a cutting tool?

Dia­mond cut­ting tools pro­vide many ben­e­fits includ­ing the excel­lent qual­i­ty fin­ish on the com­plet­ed part, decreased tool changes, decreased scrap, and increased machine utilization.

What is the difference between PCD and CBN?

Both PCD (poly­crys­talline dia­mond) and CBN (cubic boron nitride) tools have their own appli­ca­tion range and advan­tages in man­u­fac­tur­ing. PCD is pri­mar­i­ly used for machin­ing non-fer­rous met­als, alu­mini­um alloys and fiber­glass mate­ri­als. CBN is used for machin­ing cast iron and hard­ened materials. 

What is the best practice for handling diamond tools?

While not in use, a PCD tool should be kept in a spe­cial con­tain­er. Do not allow tools to touch each oth­er: it may cause dam­age on the cut­ting edge. Do not place tools on the hard sur­face. For remov­ing chips or oth­er dirt, use a soft brush or a wet cloth.

Can a diamond tool be repaired?

The answer is yes! A PCD tool can be repaired. Some of the tool wear types can be resharp­ened or re-tipped. Our engi­neers will eval­u­ate a tool’s con­di­tion and rec­om­mend a best option for each par­tic­u­lar case.
