2. Correct use in accordance to the instructions (intended use)
2.1 Use of the machine
Machine tool for cutting and surface grinding of cylindrical and stepped ejector pins, flat ejectors,
profile stamps, punching dies, ejector bushes etc. The grinding wheels are driven by two three-phase
asynchronous motors with squirrel-cage rotors by a toothed belt drive. The force exerted by the
workpiece on the grinding wheel is always radial. The cup wheel can be aligned by a puller diamond
and set with an adjusting screw until the wear limit is reached. The workpiece is held in place by a
spring clamping prism and positioned with a stop. A linear unit with screw spindle adjustment and
visual digital output facilitates the exact (0.01 mm) positioning/advance of the workpiece before
cutting (separation) and subsequent surface grinding.

6. Care and maintenance
Maintenance, repair and troubleshooting measures:
• The ejector cutting unit should be regularly serviced and cleaned by a
skilled expert.
• The machine bearings are permanently lubricated and do not require
any maintenance.
• It is strictly prohibited to blow out the machine with compressed air
because the sanding dust may settle in the mechanisms.
• The carriage guide and the support prism must only be cleaned using
a dry cloth.
The length adjustment and the cup wheel adjustment
should be oiled semi-annually.
The retaining ring and the washer are removed for this,
and the thread is oiled with VLS 250 (Meusburger). Then
the washer and the retaining ring are re-inserted.
Adjustment
Caution: Only adj
ust the cup wheel when the motor is
running, otherwise the belt will break!

Caution! Only work with the emergency stop actuated!
To set the dressing diamond to the
desired position relative to the cutting
wheel, the adjustment plate (optional)
is screwed on to the spindle instead of
the cutting wheel. The possible
adjustment size is 0.1mm or 0.15mm
to the cutting wheel. The adjustment
plate should be mounted accordingly.
Now, using the rocker function, the
adjustment plate is drawn to the
dressing diamond and this is screwed
on and then secured with the tip up to
the set surface. Caution! After the
adjustment is made, the cutting
wheel and the disc cover must be
re-mounted!
