・
Check that the reference mark on the side of the No. 1 master jaw is within the
range of the entire stroke as shown in Fig. 13. Full stroke the jaw at least once
a day to check it before work or when supplying grease, etc. If it goes out of
the range of appropriate stroke due to loosening of the draw nut, etc., the work
may not be gripped, and this is dangerous as the work will fly out.
・
When gripping the work, use it by keeping the position of the master jaw
within the appropriate stroke range. Gripping in the center of the stroke is the
most stable for the mechanism, and the best precision can be obtained.
・
When gripping near the stroke end, the work may not be gripped
sometimes according to the deviation, etc., of the gripping part allowance
of the work, and this is dangerous as the work will fly out.
・
When gripping near the stroke end, the chuck may break and the chuck or
work could fly out.
