Note: Use of highly rigid toolholders is recommended.

Wiper edge

Wiper edge geometry● A finishing edge (wiper edge) is formed at the point of intersection between the corner radius and the straight cutting edge.

■ Effect of wiper edge

● Superior surface roughness → By integrating roughing and finishing into one process, the productivity can be increased.

● Doubles the productivity → Reduced machining time

Compared with conventional inserts only with corner radius, surface roughness can be improved with the wiper edge.

■ Profiles of surface roughness

■ Recommended toolholders for wiper-edged inserts

● Relationship between honing angle and tool life in interrupted turning● Relationship between honing angle and tool life in continuous turning

●General rule• For continuous cutting, small honing angle is favorable to minimize wear in general.• For interrupted cutting, large honing angle is favorable to minimize fracture in general.
