RGC25 Name w/key CNC Roll Grinders

Product Category: CNC Roll Grinders RGC25


    RGC25 is our versatile multi-purpose percision Roll Grinder. This machine is setup with a traversing wheelhead that uses an AC digital servomotor and a high-precision rack and pinion drive system. The worktable is stationary and with the use of the split tailstock the operator can adjust for taper. The carriage under the wheelhead has a high-precision ball screw and AC digital servomotor to drive the movement completes the infeed. Constructed of high-strength, low-stress Meehanite cast iron that has been properly aged. The guide-ways are precision machined, ground and hand-scraped for maximum lubrication distribution. 
    This crowing process is completed by the use of a hydrostatic eccentric sleeve that houses the grinding wheel spindle that also utilizes a hydrostatic bearing system. The feed system uses an AC Servo motor and precision ball screw to turn the eccentric sleeve (U-axis) causing the centerlines to shift and the infeed to simultaneously move in (X-axis) keeping constant contact. This process can generate a crowning affect on the workpiece (concave and/or convex). This process can also generate tapers and parabolic curves.
