Machining Hardened Steel With Ceramic Inserts

Pcbn polycrystalline cubic boron nitride is an advanced material that comes as a result of sintering micron cbn powders with various ceramics to create extremely hard and thermally stable cutting tools.

Machining hardened steel with ceramic inserts.

Mccarthy recalls one shop owner who hesitated initially when confronted with the speeds hard turning calls for. We formulate our secomax pcbn grades to significantly reduce production costs when machining hardened steel pearlitic cast iron hard iron and super alloys. Whatever your component or requirements for surface finish find productive insert grades here that can withstand high temperatures and cutting forces and still retain their cutting edges. Turning inserts and grades for hardened steel.

To produce just one part the shop was using two carbide inserts indexing each one time four cutting points altogether. Here s a look at some of the ways they are used. The shop was cutting 45 rc steel with carbide inserts on a three year old cnc lathe. Al2o3 tic composite ceramic commonly known as black ceramic is suitable for machining hardened materials up to 65 hrc.

Applying ceramic inserts is not a simple substitution of one cutting tool material for another. Parts made from these materials are typically case hardened requiring tools highly resistant to crater wear. Beyond 55 hrc are materials that include case hardened and most through hardened steels which require extra resistance to flank wear. Ceramic inserts provide an excellent choice for these types of applications.

Its use behavior greatly influences the key machining parameters tool life cutting speed and surface quality. Turning hardened steel calls for super hard insert grades.
