Accessories / Special Features:

 

*       Rotary workpiece feed system with infinitely variable speed adjustment prepared with

workpiece carrier disk approx. dia. 800 mm with relevant workpiece shaped pockets and

after the grinding the parts will be automatically sorted out and collected in a collector box.

*       IONIC – Size Control Unit Model Nr. 9 So with measuring probe for the ground workpieces

and with signal for the hydraulic infeed of the grinding wheel when size is not in order.

*       Automatic Dressing Device for the grinding wheels, hydraulically operated and with the automatic return of the grinding wheels after dressing cycle to the previously adjusted position and to continue the working cycle. Dressing cycle can be presetted  by a timer or a manual release.

*       Manually operated infeed device of the Spindle slide to optimal workpiece thickness.

*       Spindle drives controlled by Ampere-Meters.

*       Separate switch cabinet.   * Separate hydraulic unit.   * Various carrier disks, etc.

*       Safety covers.     *   Central lubrication.

*       Large Coolant device with paperbandfilter

 

 

This machine is ideal for double-sided simultaneous grinding of parallel workpiece surfaces by continuous method, for maximum output and accuracy in mass production (e.g. Piston rings, washers, hydraulic parts, and other punched parts.)
