Machining Hardened Steel With Ceramic Inserts

Si3n4 silicon nitride inserts have high toughness and are suitable for machining cast iron generally grey in colour.

Machining hardened steel with ceramic inserts.

Al2o3 tic composite ceramic commonly known as black ceramic is suitable for machining hardened materials up to 65 hrc. There are so many different machining tasks that can be efficiently and economically solved with ceramtec s range of cutting materials and indexable inserts for workpieces made of cast iron steel hardened steel and special materials. Mccarthy recalls one shop owner who hesitated initially when confronted with the speeds hard turning calls for. Its use behavior greatly influences the key machining parameters tool life cutting speed and surface quality.

Here s a look at some of the ways they are used. Ceramic inserts provide an excellent choice for these types of applications. 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. Beyond 55 hrc are materials that include case hardened and most through hardened steels which require extra resistance to flank wear.

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 hardened steel calls for super hard insert grades. To produce just one part the shop was using two carbide inserts indexing each one time four cutting points altogether.

Turning inserts and grades for hardened steel. Applying ceramic inserts is not a simple substitution of one cutting tool material for another.
