Liebherr segment clamping arbor SECLA

The clamping fixture for optimum quality and very fast delivery times

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).

Best results with the right clamping technology

Segment clamping technology achieves exceptional, reliable and precise clamping of the workpieces from the bore. These segment clamping arbors are suitable for a wide range of applications within gear manufacturing.

They also offer further advantages compared with standard clamping fixtures. Conventional systems often reach their limits, for example with small workpieces with interfering contours – for SECLA, this is not a problem!

For example, if the workpieces have to be chamfered up to the root diameter during the ChamferCut process, the lean design is a great advantage. Despite this lean design, the clamping system always maintains excellent stability when working with large workpieces with a massive rate of metal removal, because of the very low position of the support.
