Shaft turning chuck Ø 200 - 480 mm ■ Compensating jaw clamping ■ Face driver with fixed or spring loaded center ■ proofline ® chucks = fully sealed - low maintenance
Shaft chuck with retractable jaw Face driver
Application/customer benefits • Complete machining of shafts in one operation • The rough machining is done with compensating jaws clamping • Finish machining of the complete outline with the face driver at retracted jaws Technical features • Retractable jaws • Compensating jaws clamping • Face driver adjustable with adjusting wedges • Center point fixed or spring loaded • Pull down of the workpiece to the axial reference, ensures high position accuracy
• Case hardened internal parts • Constant grease lubrication • proofline ® chucks = fully sealed - low maintenance
Standard equipment Shaft chuck without face driver with mounting bolts
