Liebherr segment clamping arbor SECLA
Clamping systems for gear manufacturing are usually very individual and have special requirements regarding concentricity and interfering contours. For this reason, it is particularly important to find the right clamping device for the application.
Liebherr’s segment clamping arbor SECLA is an innovative, inexpensive standard solution which will be delivered to you within just ten weeks. The clamping technology reduces expensive downtimes and is suitable for all Liebherr technologies (gear hobbing, shaping, skiving, grinding).
