5-3. Precautions related to usage of jaw
23
・
If a soft jaw other than one made by Kitagawa Iron Works is used, the
engagement will be inferior, and the gripping precision will worsen, and the
work will fly out due to gripping failure, which is dangerous.
・
Do not use the soft jaw by welding to join for extension. The jaw will break due
to insufficient strength. As a result, the jaw will break, and this is dangerous
as the work will fly out.
5-4. Precautions related to processing
<1> Interference, contact, impact
・
Before starting work, check that the top jaw, locator, work, etc., and the tool
and the tool post, etc., do not interfere at low rotation and then start
processing.
・
Do not allow anything to impact the chuck, jaw, and the work. The chuck will
break and this is dangerous as the chuck and work will fly out.
・
If the tool and the tool post contact the chuck or the work due to malfunction
or tape mistake, etc., and impact is given, immediately stop the rotation, and
check that there are no abnormalities in the top jaw, base jaw and bolts of
each part, etc.
<2> Coolant
・
Unless coolant with a rust preventive effect is used, rust will occur inside the
chuck and gripping force drop may result. The work will fly out due to the
gripping force drop and this is dangerous.
