Precise, economic and flexible – ChamferCut is the future of chamfering.
Chamfering gears prevents the edges of the teeth from becoming brittle during heat treatment and reduces transportation and installation damage. Multiple processes can be chosen for this. Classic technology such as press deburring or chamfering with end mills are increasingly being superseded by CNC controlled processes such as ChamferCut and FlexChamfer.
These are extraordinarily economical and guarantee an excellent chamfer quality which can be reproduced very precisely. CNC controlled processes are easy to operate and minimize set up cost.
Liebherr knows the advantages and the limits for the various processes and individually advises customers with their selection. Requirements for an optimal chamfering process can be individually arranged by batch size, chamfer shape, subsequent machining or component geometry. Liebherr specializes in particular in the ChamferCut technology from LMT-Fette.
As a pioneer in introducing this process and its development to being production-ready, Liebherr is determined to take this further in the future: By consulting with clients, both companies are working to improve precision, productivity and usability.
