5247-E P-(i) SAFETY PRECAUTIONS

SAFETY PRECAUTIONS
The machine is equipped with safety devices which serve to protect personnel and the machine itself from hazards arising from unforeseen accidents. However, operators must not rely exclusively on these safetydevices: they must also become fully familiar with the safety guidelines presented below to ensure accidentfree operation. This instruction manual and the warning signs attached to the machine cover only those hazards which Okuma can predict. Be aware that they do not cover all possible hazards.

1.

Precautions Relating to Installation
(1) Please be noted about a primary power supply asfollows.

• Do not draw the primary power supply from a distribution panel that also supplies a major

noise source (for example, an electric welder or electric discharge machine) since this could cause malfunction of the CNC unit. no choice but to use a common ground, the other equipment must not generate a large amount of noise (such as an electric welder or electric discharge machine).

• Ifpossible, connect the machine to a ground not used by any other equipment. If there is

(2) Installation Environment Observe the following points when installing the control enclosure.

• Make sure that the CNC unit will not be subject to direct sunlight. • Make sure that the control enclosure will not be splashed with chips, water, or oil. • Make sure that the control enclosure and operationpanel are not subject to excessive
vibrations or shock.

• The permissible ambient temperature range for the control enclosure is 5 to 40°C. • The permissible ambient humidity range for the control enclosure is relative humidity 50%
or less at 40°C (no condensation).

• The maximum altitude at which the control enclosure can be used is 1000 m (3281ft.).

Points to Check beforeTurning on the Power
(1) Close all the doors of the control enclosure and operation panel to prevent the entry of water, chips, and dust. (2) Make absolutely sure that there is nobody near the moving parts of the machine, and that there are no obstacles around the machine, before starting machine operation. (3) When turning on the power, turn on the main power disconnect switch first, then the CONTROLON switch on the operation panel.

Precautions Relating to Manual/Continuous Operation
(1) Follow the instruction manual during operation. (2) Do not operate the machine with the front cover, chuck cover, or another protective cover removed. (3) Close the front cover before starting the machine. (4) When machining the initial workpiece, check formachine operations, run the machine under no load to check for interference among components, cut the workpiece in the single block mode, and then start continuous operation. (5) Ensure your safety before rotating the spindle or moving a machine part. (6) Do not touch chips or workpiece while the spindle is rotating. (7) Do not stop a rotating part with hand or another means. (8) Check that thecondition of hydraulic chuck jaws as mounted, operating pressure, and maximum permissible revolving speed. (9) Check the condition and location of the cutting tool as mounted. (10) Check the tool offset value. (11) Check the zero offset value. (12) Check that the SPINDLE OVERRIDE and FEEDRATE OVERRIDE dials on the NC operation panel are set to 100%. (13) When moving the turret, check the software limitsfor X- and Z-axes or the locations of limit switch dogs to prevent interference with the chuck and tailstock. (14) Check the location of the turret. (15) Check the location of the tailstock. (16) Cut workpieces with a transmitted power and torque within the permissible range. (17) Chuck each workpiece firmly. (18) Check that the coolant nozzle is properly located.
