1. Chuck Table Replacement
Safety precautions for chuck table replacement
When the size of the workpiece or frame is changed, it is necessary to replace
the chuck table.
WARNING
Since chuck table replacement is to be made with your hands placed
in an axis operation section, your hands or fingers could be caught or
cut off. Be sure that no other person touches the machine during
chuck table replacement.
While you don't use the touch panel, press the button
located at the upper left of the screen in order to lock up and
deactivate the touch panel.
CAUTION
- If a scratched chuck table is set in position, the chuck table flatness
precision will be adversely affected. Before installing the chuck
table, make sure that the table base and chuck table surface are
not scratched.
- If the table setup procedure is performed with a wrong chuck table
size, the surface of the chuck table may be damaged. After chuck
table replacement, set the chuck table size of the setup data.
- If the chuck table is replaced without executing setup, the cutting-
induced blade wear amount accumulated since last setup is not
subtracted from the actual blade tip protrusion amount data, thereby
incurring work breakage during a subsequent cutting operation.
Before chuck table replacement, be sure to perform setup
operation.
NOTICE
Neither safety goggles, protective gloves, stepstools, flashlights nor
alcohol, all of which are necessary for maintenance work, are not
supplied with the machine. Use what are furnished in your factory or
what comply with your factory's standards.
