Result:
Outstanding smooth running, high surface quality and hardly any noticeable wear on the indexable insert in conjunction with
the highest contour accuracy, ensured perfect preparation of the mould for the following finishing process.
sLOTWORX

HP
has proven to be the ideal solution for this task. The extremely low insert wear also increases the cost
efficiency of this milling system.

job description:
Stock material machining of a plastic injection mould and preparing for finishing with a constant depth of cut of 0.2 mm.
The dimension created by the predecessor tool before hardening amounted to 3 mm.
Especially on inner radii and narrow grooves, the proportion of full cuts is a critical point.
This can lead to significantly increased wear on indexable inserts.
Major requirement/archivement: secure machining of the complete part without machine down time.
