High precision for low cost. Total indicated runout for valve face concentricity .0002"

No belts or electric pumps to replace. Pump is driven off the wheel spindle and direct drive motor for the grinding wheel.
The VRX Valve Grinder/Refacing machine will
reface the valve and also chamfer/recondition the valve stem butt.
