RV516 new standard
Centerless Grinding System is able to grind a set of valves to exact same length without adjusting settings. Centerless System rotates the valve stem on it's own centerline. grants a perfect concentricity between head and stem (within 0,01 mm) and handles a large range of valve stem diameters from 4 up to 16 mm, without need of changing any collets or chucks.
Centerless Grinding System
Handles large range of valve stem diameters without changing any collets or chucks!
Canted Roller Drive System
Eliminates the need to manually feed valves into or away from grinding wheel during refacing. Canted rollers feed valves against a precision stop which accurately controls valve length on every valve - automatically.
 
 
Variable Valve Rotation Speed-optional
Allows the operator to adjust surface speed for different diameter valves for best surface finish on a wide range of valve head diameters from small multi valve to large diesel valves.
 
 
Wheel Diamond Dresser
The fold away diamond dresser is set to the exact position of the wheel face to dress, just drop the dresser down into place and the diamond is positioned, ready to dress minimum material from the main grinding wheel.
 
Solid Cast Iron Construction
Eliminates chatter, and maintains accuracy for a long service life.
Open Sided Steady Rest
No need to switch off the motors when changing valves, reducing machining time and increasing the life of motors.
 
Dual purpose stroking handle
The stroking handle has the dual purpose to move the valve back and forth over the grinding wheel and also lifts the rotation driveroller away from the valve stem to allow the valve change without switch off the driving motor.
