Detailed Specification



MDE is an automatic indexing chuck with hydraulic clamping and indexing. It is not self-centering.


• made in special high resistance hardened and cementing 60HRC steel UNI18NiCrMo5, to maintain a high degree of precision, reliability and quality

• indexing movement (tecnomors patent) simple reliable with only a piston that works in rotation and in clamping position. Indexing precision ± 1’

• guiding system of clamping and of the indexing mechanism. This system uses 2 pre-loaded solid straight roller radially and 1 axial bearing

• seals against contamination by coolant, chips or dust

• constant and long lasting precision

• easy installation to the machine

• the chuck is connected to the rear rotating oil manifold thanks to the nest tube. This tube system is supplied with grinding hardened steel clutch’s

• centrifugal force compensation system for parts susceptible to deformations to obtain an higher productivity performance

• indexing control device

• a good automation system level grows using robot to load and to unload workpieces

• indexing process is possible also in rotation position to allow a fast indexing position passage. The rotation speed has to be not at the maximum power

• indexing takes, with position control, approx. 2-4 seconds per 90°, depending on the size of the chuck

• very simple hydraulic system based on 2 indexing mechanism ports, 2 clamping pistons ports and 1 manifold drain

• the chucking piston is connected to a safety device and keeps the working securely gripped in the jaws even in the event of a complete pressure loss
