1. Precautions for machine tools
(1) In order to ensure the precision of the machine tool, the installation location must meet the following requirements
has. Ambient temperature 17 ~ 25°C
b. The humidity in the workshop is 40% to 75% at an ambient temperature of 20°C (non-condensing).
c. Sunlight should not shine directly on the machine tool. The environment around the machine tool should not be subject to strong vibrations, dust, acidic corrosive gases or salty substances.
(2) The power supply must meet the following requirements
A. Supply voltage AC200V
b. Voltage changes by 10% or less
c. Power frequency 50/60 Hz
d. It should be avoided that the source of large electrical noise (electric welding machine discharge processing equipment) and the machine use the same power distribution cabinet, otherwise it will cause the NC device to malfunction. The ground wire must be connected separately. whenever possible and should be avoided as a last resort. The sources of electrical noise generation (electric erosion machining equipment of electric welding machines) are shared.
(3) Installation environment The following points should be paid attention to when installing the control cabinet: a. Avoid direct sunlight on the NC device. b. The control cabinet must not be damaged by cutting chips, water, oil, etc. ; . The control cabinet and the control panel must not be subjected to vibration or shock; d. Control The ambient temperature of the cabinet is 0 to 40°C. The humidity of the control cabinet is 30-95% (non-condensing). the altitude of the control cabinet is less than 1000 M
2. Confirmation items when turning on the power
(1) To prevent water, chips and dust from entering, the doors of the control cabinet and control panel should be closed.
(2) The machine tool can only be started after confirming that there are no people or obstacles in the moving part of the machine tool.
(3) When turning on the power, first turn on the main power switch, then turn on the power switch on the control panel.
3. Operation precautions
(1) After powering on, please check and adjust according to the daily inspection requirements in the manual.
(2) Tools should be selected according to the work content and machine tool specifications. Tools that are easy to carry often become the cause of accidents, so it is better not to use these types of tools.
(3) When the spindle is indexing, it is absolutely forbidden to touch the spindle and the tool with your hands because the spindle is rotating.
(4) Confirm whether the processed parts and tools are securely fixed
(5) It is absolutely prohibited to touch rotating processing parts and tools with hands.
(6) During the machining process, chips cannot be removed by hand. To remove the chips, the machine tool must be stopped.
(7) Do not start the machine tool with various safety devices removed, and try to avoid starting the machine tool with the machine tool protective shell and protective plate removed.
(8) When installing and disassembling the tool, the machine tool must be stopped before continuing.
(9) Do not approach or touch the moving parts of the machine tool during operation
(10) Do not touch various switches with wet hands as this is very dangerous.
(11) Carefully check the various switch buttons on the operation control panel before use.
4. Precautions for ATC
(1) The tools in the tool magazine and the spindle must be firmly clamped. It is very dangerous for tools to fall due to abnormal accidents. Therefore, please do not approach the ATC with your hands during operation.
(2) When inspecting and replacing tools in the ATC tool magazine, the tool magazine must be in the manual input state.
(3) If there is iron filings attached to the tool magazine, it will often cause trouble, so it should be removed in time. However, if you use compressed air to remove it, the iron filings will be blown away, so do that. do not use this method.
(4) If the ATC stops midway for any reason, the inspection should not be carried out without turning off the power supply. Because it may move suddenly, please do not touch it with your hands during inspection.
5. Things to note at the end of the work
(1) Please clean around the machine tool after finishing the operation
(2) Drive ATC APC and other devices to the predetermined position
(3) After the operation is completed, the power should be turned off when leaving the machine tool.
(4) The procedure for turning off the power supply is to first turn off the power switch on the control panel, and then turn off the main power switch.
6. Maintenance inspections and precautions for abnormal conditions
In order to avoid damage to machine tools caused by unpredictable accidents, it is necessary to pay attention to the following points when performing maintenance inspections or troubleshooting machine tools:
(1) When an abnormality occurs, press the emergency stop button to stop the machine tool.
(2) Maintenance personnel should handle the problem after fully understanding the cause of the abnormality.
(3) Personnel involved in maintenance should cooperate in an orderly manner when carrying out joint operations.
(4) Spare parts such as fuses should be replaced according to the specified specifications.
(5) Please turn off the power supply while inspecting and replacing the part.
(6) If the machine tool parts need to be dismantled during inspection and repair, they must be restored after the work is completed and the mounting screws must be securely tightened.
(7) When measuring voltage, etc., a calibrated measuring instrument should be used.
(8) Please do not place flammable or metal objects in the terminal box of the control cabinet.
(9) Damage to cables and wiring can cause leakage and induction, so check the integrity of cables and wiring.
(10) Concerning the maintenance of the control cabinet
a) When opening the control cabinet, the main switch must first be turned off.
b) Even if the main switch is turned off, charges remain in the MCS drive device (servo amplifier/spindle driver). Therefore, other than maintenance personnel, please do not touch these devices with your hands if maintenance personnel wish to do so. touch these devices with your hands, please follow the steps below Method: Discharge the MCS drive device (servo amplifier/spindle drive) with the main power switch OFF for 2 minutes.
c) An NC device is installed in the control cabinet. The device’s circuit board contains storage of the treatment program parameters. The circuit board can still keep the stored content even if the power is turned off. memory. Improper handling can damage the memory. Therefore, please do not touch the circuit board except for maintenance personnel.
(11) Regular inspection of the control cabinet
a) Clean the cooling device regularly. The cooling device installed in the control cabinet door can suppress the temperature increase in the control cabinet. In order to improve the operating reliability of the NC device, please check it every three months. Check if the cooler fan motor is running. If the wind is strong, this can be considered normal; If the air suction port of the cooling device is blocked, please use compressed air to clean it. .
7. Precautions for personnel operation
(1) Please tidy up and clean the area around the machine tool regularly.
(2) Wear appropriate and safe clothing when working and do so under the direction of properly trained persons.
(3) Clothes and hair may get caught in the machine tool. Particular attention must be paid when working. Operators must wear safety shoes, protective glasses and other safety protective equipment.
(4) Operators should read the operating and installation instructions carefully before using, and start the machine tool after confirming that their operations are correct.
(5) The location of the emergency stop switch should be kept in mind so that you can quickly press it at any time from any position.
(6) There are high voltage terminals and other parts inside the control panel, transformer, motor, etc. Because they are very dangerous, please do not touch them.
(7) When two or more people are working, they must coordinate and mutually confirm their movements before continuing.
