Before Starting Operations

This section deals mainly with the operating procedures of your CNC lathe under manual control. So
the information given here is essential to every operator, whether you are new to a CNC lathe or an
"old pro".
Follow these three points:
•
Actually operate the CNC lathe by yourself in reference to this Instruction Manual.
•
Learn the symbols for the numerical control terms.
•
After you have a general idea of how your CNC lathe operates, read this manual repeatedly and
also the Programming Manual.
CAUTION
Bring the machine to a complete stop by turning off the main switch before operations
such as setup or adjustments inside the chip guard are carried out.
Also turn off the main switch before you attempt to work inside the machine at the rear
side of the machine.

instructions:
(1) Setting of hydraulic power chuck jaws and their gripping pressure
(2) Installation and arrangement of individual cutting tools with respect to their operating sequence
(3) Setting of tool offsets
(4) Setting of zero offsets
(5) Setting of feedrate override to 100%
