2. Select Bending Mode
- Choose the appropriate bending mode, such as single bend or continuous bend.
3. Input Bending Parameters
- Enter the desired bending angle and depth on the control panel.
4. Start the Bending Process
- Press the "Start" button to begin the bending operation.
Maintenance Procedures
Regular maintenance is crucial to keep the CNC press brake functioning efficiently. Here are the key maintenance tasks:
1. Hydraulic System Maintenance
1. Check Oil Level Weekly
- Inspect the hydraulic oil level in the tank weekly and replenish if necessary.
2. Replace Hydraulic Oil
- Change the hydraulic oil every 2000 operating hours.
3. Clean the Oil Tank
- Clean the oil tank every 4000-6000 hours of operation.
4. Monitor Oil Temperature
- Maintain the system oil temperature between 35°C and 60°C.
2. Filter Maintenance
1. Change or Clean Filters
- Replace or clean the filters every time you change the hydraulic oil.
2. Inspect and Replace Filters
- Replace the filter if the oil is dirty or the filter shows signs of malfunction.
3. Air Filter Maintenance
- Inspect and clean the air filter on the oil tank every three months and replace it annually.
3. Hydraulic Component Maintenance
1. Monthly Cleaning
- Clean hydraulic components, including the base plate, valves, motors, pumps, and oil pipes monthly.
2. Check Oil Pipes
- Inspect oil pipes for deformation after the first month of use and tighten all connections after two months.
