Precautions for maintenance before and after the Spring Festival

　　clean up

1. Cleaning of iron filings: Iron filings that accumulate for too long are prone to rust, clumping, and have a significant impact on the telescopic cover of the chip conveyor. Cleaning of the interior of the machine tool/T-shaped groove of the worktable/chip conveyor/telescopic cover, as well as the interior of the water tank, etc

2. Cleaning of various filters: electric cabinet air conditioning, heat exchanger filter screen/oil-water cooler filter screen/hydraulic station heat sink/guide rail oil filling port filter screen, etc

　　rust prevention

1. Apply oil to the surface of the workbench and the surface of the retractable cover when opened

2. Apply oil to the inside and cross-section of the spindle taper hole (remember not to clean the spindle with an air gun to prevent impurities from entering the bearing)

3. Balance chain and sprocket (clean and apply butter)

4. Chain type chip conveyor transmission chain

5. Rust prevention for each fixture

　　Cutting fluid section

1. It is recommended to extract the cutting fluid (water-soluble) and clean the water tank (water-soluble cutting fluid will spoil and deteriorate after being left for a long time)

2. Generally, water-soluble cutting fluids are aerobic. If the cutting fluid is isolated from air or covered with oil stains on the surface, it will cause the cutting fluid to deteriorate and decay

3. Cutting fluid can pollute the environment, so do not discharge it directly

　　Gas source section

1. Drain the moisture from equipment such as air storage tanks, refrigerated dryers, dryers, and cyclone water removers. Drain the moisture from the filter tank on the machine tool. Use the pneumatic energy on the machine tool to repeatedly operate and try to drain the moisture from various components and pipelines, such as loosening the clamping tool, blowing air during processing, lifting the tool sleeve up and down, or using a four axis loosening clamp

2. Moisture in the air source can cause significant damage to the gas components of the machine tool, such as the spindle, grating ruler, cutting cylinder, air cylinder, solenoid valve, etc

　　Guide rail section

1. Check for impurities or delamination at the bottom of the lubrication pump. If the above phenomenon occurs, it is necessary to pour out the oil and clean the interior and oil suction filter screen

2. It is recommended to use genuine guide rail oil, especially not recycled oil

3. Manually pump oil multiple times, move the three-axis full stroke multiple times, and let the guide rail oil coat the screw, guide rail, etc

4. Before shutting down, move the three-axis to the middle position, record the mechanical coordinates of the three-axis at this time, or take a photo, or record it in coordinates such as G54/55, to prevent the origin from being lost due to battery voltage during later startup
