Ecotech's CNC Cylindrical Roll Grinders have heavy aged cast iron construction, that has been precision machined and hand scraped. With a Hydro-Dynamic spindle on the wheel head and the Hydro-Static lubrication system on the table, these machines will give you many years of trouble-free operation and high accuracies.
The large Roll Grinders use the SIEMENS high-performance control. This control has been developed exclusively for the CNC Cylindrical Roll Grinder. SGS Grinding Star” is special user-friendly programming software used to control grinding of the convex crowns and/or concave curves.
The system can store all your cylindrical roll programs, grinding time and inspection data on the L3 computer management database. The output format is determined by the programmer. We have developed a state-of-the-art CNC Cylindrical Roll Grinder with the simplicity of programming today’s most complex parts.
The RGC series is our versatile multi-purpose precision Roll Grinder. This machine is set up with a traversing wheel head 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 wheel head 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 crowning 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 effect on the workpiece (concave and/or convex). This process can also generate tapers and parabolic curves.
