Use of the clamp
The machine is supplied with the ‘J1’ standard clamp illustrated in fig. 15.
Fig. 15
As shown in fig. 15, the ‘J1’ clamp has a fixed plate (R1) on top and a mobile jaw (P1), both of
which can be replaced when worn.
The clamp also has a setting plate (T) for the Z axis (sprung), over which the cutting tool zeroes
before starting cutting operations on a new key. The plate is sprung to avoid microfractures when
the cutting tool makes contact with it.
WARNING:
to ensure that the Z axis works accurately, keep the setting plate (T) perfectly clean by
brushing any metal chips off regularly, using the brush provided.
WARNING:
do not exert excessive pressure to lock the key in the jaws. Turning the knob
approximately 70˚ (clockwise) when the jaws start to grip the key is sufficient (fig. 16). It is
also important to ensure that the key lies absolutely flat in the jaw during locking so that
it cannot bend, twist or rest unevenly on the plate (fig. 16).
