Applications:
Cylindrical grinding --- taper grinding --- form grinding ---
polygon grinding --- plunge-cut grinding --- smallest diameter grinding
On your surface grinding machines!
Mode of use
1. Set the RAPID mini on the magnetic table of the surface grinder. Adjust the right-angled
groundplate to the stop ledge of the magnetic table and switch the magnet on.
2. Place the workpiece under the centre of the grinding wheel.
3. Select with or the sense of rotation and spindle start.
4. Determine the highest point of the workpiece by moving the machine-table.
5. When grinding cylindrical and taper parts, the timing belt must be tightened and the index bolt
must be unlocked!
Switch the motor on and let the workpiece rotate.
6. When grinding surfaces or polygons, the timing belt must be loosened.
For this, the clamping screw for the motor bracket must be released.This screw is on the
bottom of the block. Then you can move the motor along the slot.
7. The motor must be switched off and the index bolt must be locked.

Taper grinding:
Slewable up to 45° (relative 90°). Use gauge block according attached sine table.
Up to +45° angle position place the gauge block underneath the front sine axle.
When minus degrees are necessary, position the gauge block underneath the rear sine axle.
At an angle +90°, adjust both sine axles vertically.
Grinding with tailstock and rigid center punch:
Please observe heat development, thin workpieces may bend.
Motor-temperatures up to ca. 60° are harmless.
Workpiece change:
Lock the spindle with the index bolt. Loosen, respectively tighten the collet chuck with the hook
spanner.
