Valve refacing machines
On a centerless valve refacing machine, the valve is guided by its stem, with no collet or chuck: the face is concentric to the stem, with runout below 0.005 mm. The VR Series grinds the face, the stem and the stem tip, with chamfering.
From the small multi-valve engine valve to the large diesel or gas valve: rotation, wheel speed and face angle are adjusted for each valve.
