Rottler Manufacturing Valve Refacing Machine VR7

Precision Chuck System Pneumatic Operated Quick Action 2 X 3 Ball Precision Chuck driven by large, heavy duty variable speed gear motor. The 2 X 3 ball chuck allows a wide range of valve stem diameters to be ground without changing any parts - no collets or wrenches! The 2 X 3 ball chuck gives extremely accurate run-out for improved sealing, better heat transfer and reduces mechanical stresses on valves. Linear Roller Bearing Slideway Hardened steel precision ground linear roller bearing slideways allow easy stroking of the wheel slide reducing operator fatigue and improving surface finish on the valve seat face for improved sealing and cooling. No friction and wear associated with dovetail slideways. Featherlite stroking with linear slideways requires only one finger to move the wheel back and forth over the valve.
