7) Tighten the bolts on the chuck body, jaws, and block securely. Clamping force should be
greater than 40 to 50 kg.
CHECKUP AROUND THE MACHINE
1) Before starting daily operations, always check the lubrication oil levels.
2) Always use the specified brand or grade of lubrication oil.
3) For cutting fluid (coolant), use Okuma’s recommendation whenever possible.
4) Change and replenish lubrication oil for each reservoir at the predetermined schedule as
explained in the operation & maintenance manual.
5) Clean the filters periodically according to the schedule explained in the operation & mainte-
nance manual.
6) Check the pressure gauges of the air and hydraulic lines to make sure they all read the correct
values as specified in the operation & maintenance manual.
7) For any work required inside the machine door, turn off power and ensure safety beforehand.
For work done at the back of the machine that requires the operator to enter the machine
operating zone, do not forget to turn off power before attempting any work.
PRECAUTIONS FOR MACHINE OPERATIONS
1) Always follow the instructions given in the operation manuals.
2) Never run the machine without protective covers and doors, such as the front door and chuck
cover.
3) Close the front door first before starting the machine.
4) With a new program, never attempt to start actual cutting operations. First run the program
without setting a workpiece in the machine to check machine operations and interference;
after making sure that the program is completely free of bugs, cut a workpiece in the single
block mode operation. Only after making sure that the workpiece can be cut without prob-
lems in the single block mode operation should the automatic mode operation be started.
5) Before attempting the following, always make sure that untended operation can be accom-
plished safely:
Spindle rotation
Turret indexing
Axes movements
6) While the spindle is revolving, never touch chips or the workpiece.
7) Never try to stop a revolving object with hands or tools.
8) Confirm the jaw installation conditions, hydraulic pressure, and allowable maximum speed
for the power chuck.
9) Check the installed conditions and arrangement of the tools.
10) Confirm the tool and zero offset settings.
11) Set the spindle speed and feedrate override dials to 100 %.
12) Before feeding the turret, confirm the soft-limit settings and the emergency limit switch
settings for both X and Z axes.
13) Confirm the position where the turret index or rotation is allowed.
14) Confirm the tailstock position.
15) Make sure that cutting is conducted within the allowable transmission power and torque
ranges.
16) Clamp the workpiece in the chuck or fixture securely.
17) Check the cutting fluid nozzle positions. Set them at positions to supply cutting fluid cor-
rectly to the cutting point.
