Efficient production of bores accurate in
dimensions and design on single-spindle
and multi-spindle machines. RÖHM designed
special floating chucks for reamers with
internal coolant supply.
The tool locating sleeve is moving on precision
balls and coupled to the chuck body through an
Oldham type clutch, driven by means of precision
rollers. Therefore the tool retains all its mobility
independent of the torque resulting of the cutting
force. A new patent conception prevents any
destruction of the bearing through the balls due
to an incident (breaking of the tool, program
error, shocks, very high cutting load, etc.).
Technical features: • the floating chucks are suitable for vertical, horizontal, as well as for right- and left-hand rotation • for the SMP Compact only the radial movement is adjustable • a patented, not deformable intermediate piece with two Viton seals connects floating sleeve and body • these floating chucks with internal coolant supply can be used with non-tight standard collets • we offer three different capabilities of connecting: coolant supply through the centre - lateral fixed - lateral rotating
