Inserts

Seco offers the MP2050 insert grade with an optimized balance of toughness and wear resistance to efficiently machine high-strength, heat-resistant materials. Originally developed specifically for turbine blade machining in the power generation industry segment, the new grade also excels in aerospace applications and offers exceptional performance in milling materials such as austenitic and martensitic stainless steels, as well as titanium.

THINBIT offers CBN- and PCD-tipped inserts. CBN (cubic boron nitride) tipped inserts provide an increased production rate, improved surface finish and dimensional control when used on high-temperature alloys, such as inconel, nickel-base alloys and materials with a hardness of HRC 35 or harder.

Seco Tools has introduced its R217/220.28 cutters with new body designs that incorporate double-sided round inserts to deliver cost-effective performance, as well as boost productivity. Double-negative-positioning pocket seats of the R217/R220.28 cutters deliver enhanced cutting capability and significant gains in productivity, according to the company.

Sumitomo Electric Carbide, Inc.’s new AC1030U high-precision, small-parts machining grade combines “Absotech Bronze” PVD coating and a special substrate for superior wear- and chipping-resistance. In addition, the high-quality cutting edge of the AC1030U ensures excellent resistance against adhesion and microchipping for improved surface finishes, according to the company.

Customers have been asking for a new carbide grade to machine titanium 6Al4V at higher cutting speeds compared to increasing feed rates or increasing depth of cuts in that result in increased cutting forces imposed on the workpiece, fixtures and machine spindles. The KCSM40 grade has an advance cobalt binder that provides thermal fatigue resistance without sacrificing the toughness customers have experienced with KC725M or X500.

New from Sumitomo Electric Carbide Inc., AC4010K and AC4015K series turning grades for cast iron feature recently developed technologies that result in a long and stable tool life. Consisting of a smooth cutting edge treatment, the AC4000K series’ use of high adhesion technology drastically improves peeling resistance, according to the company.

Walter says its new FM5 finishing and RM5 roughing indexable insert geometries deliver optimal cooling, longer tool life, and increased productivity in high-temperature alloy and stainless-steel machining. The new inserts owe their effectiveness, in part, to their "jet guiding geometry," or targeted cooling.
