SINGLE-SIDED ISO INSERTS APPLICATION RANGE

-R58

Universal geometry for virtually all materials

Fo r interrupted cuts

Suitable for unstable conditions thanks to the low cutting forces

-R88

For large depths of cut and high feed rates

High process security even on irregular forging and cast skin

Particularly suitable for severely interrupted cuts

Customer benefits

○ Machining time reduced by approx. 1/3

○ Increased feed rate

Result

Increased process security thanks to reduced wear.

In addition the customer can maintain process security while

increasing the feed rate and thus also the metal removal rate

from 955.5 cm 3 /min to 1,365 cm 3 /min.

○ Swarf control

○ Reduced wear
