Description

Material
Mandrel mild steel.
Taper-head screw low-carbon steel
Version
Mandrel black oxidised.
Taper-head screw case-hardened.
Note
The mandrel collet is particularly suitable for finishing turned parts. By turning or milling, diameter D can be adapted to the diameter of the clamped workpiece.
Low design - no interfering clamp straps.
Tightened using a hex socket wrench or hydraulics.

* D min. = smallest diameter to which ”D” may be turned or milled.
D max. – maximum diameter when unmachined
S – maximum clamping pin travel when actuated, S = 0,1 mm
Assembly
Expand the mandrel approx. 0.1 mm over the relaxed diameter. Turn or mill the mandrel to suit the internal diameter of the workpiece. The base flange can be centred in a pocket or using dowel pins.
