What are the specific operational steps for maintaining the CNC bending machine of Manhart (Guangdong) CNC Machine Tool Co., Ltd?

**Maintenance measures and specific operating steps for CNC bending machines**
Regular maintenance is essential to ensure the stable operation of CNC bending machines and extend their service life. The following will provide a detailed introduction to the specific operation steps for maintaining a CNC bending machine, including visual inspection, lubrication system maintenance, electrical system inspection, hydraulic system inspection, machine cleaning, fastening inspection, electrical maintenance, and tool replacement and adjustment.
**1 Visual inspection**
*Check the appearance of the machine tool for scratches, collisions, and other damages.
*Check if all components are securely installed without any looseness.
*Check if the protective device is intact, without any missing or damaged parts.
**2 Lubrication system maintenance**
*Check the oil level in the lubricating oil tank to ensure that it is within the normal range.
*Clean the lubrication system, including components such as oil pipes, nozzles, and oil pumps.
*Regularly replace lubricating oil to ensure that the oil is clean and free of impurities.
**3 Electrical system inspection**
*Check the integrity of electrical components such as cables, plugs, and wiring terminals.
*Check for dust and debris inside the electrical cabinet and clean it.
*Check the working status of electrical components such as sensors and motors to ensure their normal operation.
**4 Hydraulic system inspection**
*Check the oil level of the hydraulic oil tank to ensure that it is within the normal range.
*Check the operation of the hydraulic pump to ensure that there are no abnormal sounds or leaks.
*Clean the hydraulic system, including components such as oil pipes, cylinders, and hydraulic valves.
**5 Cleaning machine tools**
*Use a soft cloth to wipe the surface of the machine tool to remove dust and oil stains.
*Clean the workbench and fixtures to ensure they are clean and tidy.
*Clean the debris, dust, and other debris inside the machine tool.
**6 Tightening inspection**
*Use appropriate tools to check the tightness of each component, such as screws, nuts, etc.
*For loose components, they should be tightened or replaced in a timely manner.
**7 Electrical maintenance**
*Regularly check the insulation performance of the electrical system to ensure that there is no leakage.
*Clean electrical components to remove dust and dirt.
*Regularly maintain the electrical system, including tightening wiring, replacing aging components, etc.
**8 Tool replacement and adjustment**
*Select suitable cutting tools for replacement according to processing requirements.
*Adjust the installation position of the cutting tool to ensure that its position and angle with the workpiece are correct.
*Regularly check the wear of cutting tools and replace severely worn tools in a timely manner.
By implementing maintenance measures and specific operation steps in the above eight aspects, the stable operation and extended service life of the CNC bending machine can be effectively ensured. When carrying out maintenance work, it is essential to pay attention to safety, follow relevant operating procedures, and ensure the safety of personnel and equipment.
