New Grade for Steel Turning Increases Tool Life
Sumitomo’s AC8025P grade for steel turning is designed to increase productivity in a variety of steel turning applications such as continuous cutting, light-interrupted cutting and interrupted cutting.
Sumitomo’s AC8025P grade for steel turning is designed to increase productivity in a variety of steel turning applications such as continuous cutting, light-interrupted cutting and interrupted cutting. The grade features Sumitomo’s Absotech platinum CVD coating combined with a tough carbide substrate to resist adhesion and cutting edge chipping. According to the company, improvements to the coating adhesion strength control residual stress while maintaining wear resistance. The smooth surface treatment is designed to improve adhesion resistance along the ridgeline of the cutting edge. When machining low-carbon steel, rolled steel and other materials prone to adhesion, the grade is designed to increase tool life by reducing problems such as peeling or chipping of the coating layer at the cutting edge and deterioration of surface finish.
