OSP-P200L-P20L Safety Precautions
Safety devices are installed on this machine to prevent accidents and ensure the safety of personnel and the machine. However, the operator must not rely solely on these safety devices, but must carefully read and thoroughly understand the following safety precautions to ensure accident-free operation.
The warning plates affixed to the machine and described in this manual cover only those hazards that our company can foresee. Note that they do not cover all possible hazards. In all operations, please pay strict attention to safety.
1. Precautions for Installation
- Observe the following precautions regarding the main power supply.
- Do not connect the main power supply to a distribution board that supplies power to equipment that generates significant electrical noise (such as welders or electrical discharge machines), as this may cause the CNC unit to malfunction.
- If possible, provide an independent ground wire for this machine. If it must be connected to a common ground with other machines, ensure that those machines (such as welders, electrical discharge machines, etc.) do not generate excessive noise.
- Installation Environment
Observe the following precautions when installing the control cabinet.- Ensure that the CNC unit is not exposed to direct sunlight.
- Ensure that the control cabinet is not splashed with chips, water, or oil.
- Ensure that the control cabinet and operation panel are not subjected to excessive vibration or shock.
- The permissible ambient temperature range for the control cabinet is 5 to 40°C.
- The permissible ambient humidity range for the control cabinet is 50% or less (at 40°C) (no condensation).
- The maximum altitude at which this control cabinet can be used is 1000m (3281ft.).
2. Points to Check Before Turning On Power
- Close the doors of the control cabinet and operation panel to prevent the entry of water, chips, and dust.
- Ensure that no personnel or obstacles are in the vicinity of the moving parts of the machine before starting the machine.
- When turning on the power, turn on the main power switch first, and then turn on the power switch on the machine control cabinet.
3. Precautions for Manual and Continuous Operation
- Be sure to follow the instructions in the instruction manual during operation.
- Do not operate the machine while any protective cover (front door, chuck cover, etc.) is open or being moved.
- Close the front door before starting operation.
- Do not attempt to run a new program without first checking its operation. Perform a dry run without a workpiece in the chuck to confirm that there is no interference, and then cut the workpiece in single block mode. If no problems are found, automatic operation may be started.
- Before starting operations involving spindle rotation and axis movement, ensure that all operating conditions are safe.
- Never touch chips or the workpiece while the spindle is rotating.
- Never attempt to stop a rotating workpiece by hand or with tools.
- Check the jaw mounting condition, hydraulic pressure, and maximum allowable spindle speed.
- Check tool mounting and arrangement.
- Check the tool offset settings.
- Check the zero offset settings.
- Ensure that the spindle speed override and feedrate override on the operation panel are set to 100%.
- Before feeding the turret, check the X-axis and Z-axis soft limit settings and emergency limit LS (limit switch) positions to confirm that they do not interfere with the chuck or tailstock.
- Check the turret indexing/rotation position.
- Check the tailstock body position.
- Ensure that cutting operations are performed within the allowable drive power and torque limits.
- Ensure that the workpiece is securely and properly clamped in the chuck or fixture.
- Check that the coolant nozzles are properly positioned.
4. Completion of Work
- Clean the area around the machine after completing work.
- Move the turret to the predetermined retract position.
- Turn off the power to the machine before leaving it.
- To turn off the power, first turn off the "CONTROL ON" power switch on the operation panel, and then turn off the main power switch.
5. Precautions for Maintenance/Inspection and Malfunctions
To prevent unexpected accidents and machine damage, observe the following precautions when performing maintenance/inspection or troubleshooting abnormalities.
- In the event of an abnormality, press the EMERGENCY STOP button on the operation panel to stop the machine.
- Consult with authorized maintenance personnel to take appropriate corrective action.
- When working in a team of two or more persons, establish signals to verify safety before proceeding to each new step.
- Use only designated replacement parts and fuses.
- Turn off the power before performing inspection or changing workpieces.
- When machine components are removed during inspection or repair, always reinstall them in their original state and securely tighten all mounting screws.
- When measuring voltage or other parameters with a meter, use a calibrated measuring instrument.
- Do not place combustible or metallic objects inside the control cabinet or terminal boxes.
- Check cables and wiring for damage. Damaged cables and wiring can cause electrical leakage, short circuits, and electric shock; therefore, verify that cables and wiring are in sound condition.
- Maintenance of the Control Cabinet
- Before opening the control cabinet doors, ensure that the main power switch is set to OFF.
- Even after the main power switch is turned off, a residual electric charge may remain in the MCS drive units (servo/spindle). Therefore, work on these units must be performed only by maintenance personnel, who must observe the following precautions.
- MCS drive unit (servo/spindle)
Wait 2 minutes for residual charge to discharge after turning off the main switch.
- MCS drive unit (servo/spindle)
- An NC unit is installed in the control cabinet. The circuit boards in this NC unit store part programs, parameters, etc. To retain the stored contents even during power-off, a battery is supplied to the memory. Improper handling of circuit boards may destroy the stored contents. Therefore, no personnel other than trained maintenance personnel should handle these circuit boards.
- Periodic Inspection of the Control Cabinet
- Cleaning the cooling unit
A cooling unit is installed on the electrical cabinet door to prevent excessive temperature rise inside the cabinet and improve the operating reliability of the NC unit. Inspect the following points every three months.- Is the fan motor of the cooling unit rotating?
It is judged normal if air blows strongly. - Is the air intake of the cooling unit clogged?
- Is the fan motor of the cooling unit rotating?
- Cleaning the cooling unit
6. General Precautions
- Keep the area around the machine clean and tidy.
- Wear appropriate safety clothing during work, and perform operations under the guidance of fully trained personnel.
- Take special care during operation as clothing and hair may be caught in the machine. Operators must be equipped with personal protective equipment such as safety shoes and protective glasses.
- Operators must read the instruction manual thoroughly before operation and start the machine only after confirming that their operating procedures are correct.
- Keep the location of the emergency stop switch firmly in mind so that it can be pressed accurately at any time from any position in an emergency.
- High-voltage terminals are located inside control panels, transformers, motors, etc. Do not touch them, as this is extremely dangerous.
- When two or more persons work together, coordinate closely and confirm each other's actions before proceeding to the next operation.
