1. Pre-class maintenance
(1) Before driving, check whether the oil pools are short of oil, and use the clean oil to perform a refueling as shown in the lubricating chart.
(2) Check if the appearance and function of the power switch are good and the grounding device is complete.
(3) Check for looseness and loss of screws, heads, handles, handballs, and cups, etc., of each component. If it is found, it should be tightened and filled in time.
(4) Check the drive belt condition.
(5) Check if the electrical safety device is good.
2. Maintenance in class
(1) Observe the sensitivity, reliability, temperature rise, sound and vibration of motors and appliances.
(2) Check the sensitivity and reliability of the electrical safety equipment.
(3) Observe the temperature rise, sound direction and vibration of each transmission component.
(4) Check the working conditions of the plunger pump in the bed and the lift platform at all times. When the machine tool is running and no oil flows out of the indicator, repair it in time.
(5) Axial gaps in the longitudinal screw of the table and clearances in the drive were found. Adjustments should be made according to the instructions.
(6) Spindle bearing adjustment.
(7) Adjustment of the quick-moving clutch on the table.
(8) Adjustment of the tightness of the drive belt.
3. After-class maintenance <br>Before work, you must inspect and clean the equipment and do the daily maintenance work. Put each operation handle (switch) in the neutral position (zero position) to pull the power switch to achieve neat, clean, lubrication and safety. .
Regular maintenance
1. Every 3 months, the grease pool inside the bed, the inside of the lift platform and the base of the workbench is cleaned, and the oil net of the oil pump is used to clean the oil pump, not less than twice per year.
2. The lifting screw is lubricated once every two months with aluminum disulfide oil.
3. Adjustment of the clearance of each part of the machine tool:
(1) Adjustment of spindle lubrication must ensure that there is a drop of oil per minute.
(2) The adjustment of the longitudinal screw transmission gap of the table shall be adjusted every 3 months or adjusted according to the actual conditions of use. The requirement is that the transmission gap shall be fully reduced, the clearance of the screw shall not exceed 1/40 turn, and at the same time the full length There must be no jamming.
(3) The adjustment of the axial clearance of the longitudinal screw is designed to eliminate the transmission gap between the screw and the nut, and at the same time, to minimize the clearance between the axial direction of the screw and the table.
(4) The adjustment of the radial clearance of the main shaft bearing is adjusted according to the actual use conditions.
4. Adjustment requirements for the quick-moving clutch of the table
(1) When the friction clutch is disengaged, the total clearance between the friction plates should not be less than 2 to 3 mm.
(2) When the friction clutch is closed, the friction plate should be tightly pressed, and the iron core of the electromagnet should be fully tensioned. If the core of the electromagnet is properly mated, the electromagnet will not have noise in the tensioned state.
