Live centre


NEIDLEIN type RKA Live Centres are used in turning applications for heavy work pieces with large centre holes.

The modular clamping system ensures a high degree of flexibility. It is possible to clamp work pieces with centre holes from Ø50mm to Ø460mm.
Centres up to Ø115mm can be retained with the basic retainer body. For larger centres the suitable centre cones have to be adapted additionally.
Special centre cones with e.g. 90°, 70° or with various diameters can be manufactured upon customer’s request.

The true run-out accuracy of the basic body is 0,005mm max. and the total run-out accuracy including taper cone is 0.01mm max.
