・
Disassemble and clean the chuck at least once every 6 months or every
100,000 strokes (once every 2 months or more for cutting cast metal). If
cutting powder or other substances stagnate inside the chuck, it will lead to
insufficient stroke and a drop in the gripping force, and this is dangerous as
the work will fly out. Check each part carefully and replace any part that is
worn or cracked.
・
After inspection, apply sufficient grease in the designated areas and
reassemble.
・
After assembling, measure the gripping force according to the method on
page 17, and check that the specified gripping force is obtained.
・
If you stop the machine for a long period of time, remove the work from the
machine. If you don't, the work can drop due to a drop in the hydraulic
pressure or the cylinder can stop or malfunction.
・
If you stop the machine or store the chuck for a long period of time, add
grease to prevent rust.
