Use of SECLA segment clamping technology during generating grinding of extremely precise components for cycloid gears

The Liebherr segment clamping technology during generating grinding of final drive gears

Segment clamping bushings from 20 mm to 200 mm diameter

Clamping element (segment clamping bushing with tension adapter)

SECLA provides a complete segment clamping arbor system (incl. test workpiece and upper mounting for counter columns)

The SECLA segment clamping arbor also clamps workpieces during generating grinding

Application examples for the clamping system in gear technology

One segment clamping arbor with various workpiece supports and variously sized clamping elements (segment clamping bushing and tension adapter)

Optimal use for large and very small workpieces despite interfering contours
