AC1030U Grade Features Absotech Bronze PVD Coating

Sumitomo Electric Carbide Inc.’s AC1030U high precision small parts machining grade combines Absotech Bronze PVD coating and a substrate for wear-and chipping-resistance. In addition, the cutting edge of the grade provides resistance against adhesion and microchipping for surface finishes, the company says.

The Absotech Bronze PVD coating includes a smooth anti-chipping layer for surface finishes, a hardness/heat resistance layer for wear resistance and adhesion technology for peeling resistance. The carbide substrate also provides chipping resistance.

The grade can be used for high precision cutting of small parts consisting of soft steel, carbon steel, stainless steel, brass, cast iron and exotic material. According to the company, the FYS Chipbreaker offers improved chip control and crater wear in soft material machining, as well as reduced damage to the cutting edge with the AC1030U. Application examples include stator shafts, valve bodies, structural steel pipes and sensor housings.
