Long Tool Life and Stable Machining

Rigid, safe, and secure cut-off operations


Common Bottlenecks

During cut-off operations, insert cutting widths of only a few millimeters are used to cut to the center of the workpiece. This is usually the final process and is often the bottleneck. Stable tool life without sacrificing productivity is required.

Cut-Off Challenges

Due to the narrow insert, blade widths, and longer overhangs, rigidity is difficult to achieve. Cutting speed reaches zero at the center of the workpiece, increasing cutting load. Chip control issues and tool damage are common problems during these types of operations.

Cut to the Chase with the KPK-Series

To overcome these issues, Kyocera designed each element of the unique KPK-Series of tool blocks, blades, and inserts to work in unison, providing a setup with superior rigidity, toughness, and total chip control to keep your parts spinning and lower those production downtimes.

JCT-Series Jet Coolant-Through Styles

JCT series supports internal coolant for improved tool life under normal pressure. Coolant is supplied directly to the rake and the flank face of the cutting edge for increased tool life and improved chip control.
