RV 516 Valve Refacer COMEC

RV 516 centerless valve refacer is, thanks to the technical solutions adopted, one of the fastest and most accurate machine now available on the market. The centerless grinding system, with the rotation of the valve on its stem, 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.
The drive system of valves is given by three rollers, the upper of which is canted in order to feed valve against an adjustable precision end stop: this offers an accurately valve controls length on every valve and avoids to manually feed valve into or away from grinding wheel during refacing.
