Loosen the screw (7) on the punch fastener and pull the
punch (10) downwards out of the tool. Thoroughly lubricate
the new or reground punch and insert it from underneath.
Retighten the screw (7) on the punch fastener.
Attach the guide plate (11), the hold-down device (12) and
the die (14) as described above.
Regrinding the punch
Regrinding the punch in good time (e.g. with a diamond
grinding disc) can often prevent the punch (10) from chip-
ping. Severely damaged punches must not be reground.
The punch must not be reground by more than 1 mm. Grind-
ing must only be carried out on the cutting face and at ex-
actly 90° to the centre axis.
Gently sharpen the cutting edges of the punch using a fine
whetstone.
