Valve Refacing Grinder VRX
The VRX Valve Refacing/Grinder is a precision machine designed to reface valves and chamfer or recondition valve stem butts with high accuracy. Featuring a direct-drive motor for the grinding wheels, it eliminates belt slippage and ensures consistent grinding power. The machine is easy to operate, with a rigid cast base for stability and dovetail guide carriages that allow precise clearance adjustments. Valve heads are clamped in a collet system that guarantees tight concentricity and accurate centering, while the valve head stock adjusts from 15° to 60°, enabling versatile operation.
Additional features include hand-crank and handle-fed feeds for the grinding wheel and chuck, positive stops for repeatable valve stem grinding, and V-ways for consistent chamfering. The VRX uses water-based coolant supplied via a gear pump and settling tank for a superior finish and easy cleanup. Multiple high-quality grinding wheels accommodate different valve materials, and two sizes of ball chucks allow ultra-precise operations with a tolerance of 0.0002 TIR, making it ideal for high-precision, high-efficiency valve refacing tasks.
