The second-hand double-head CNC lathe is a high-precision machine tool that performs various turning processes on shaft parts and disc parts. With the development of industry, the requirements for the machining accuracy and surface roughness of mechanical parts are increasing, and the requirements for the accuracy of lathes are also getting higher and higher. It plays an increasingly important role in industries such as automobiles, electric power, shipbuilding, and metallurgy.

Daily oil change maintenance instructions for second-hand CNC lathes:

1. Check whether the air blowing of the cone hole in the spindle is normal, wipe the cone hole in the spindle with a clean cotton cloth, and spray light oil.

2. Check the lubricating oil level to ensure the lubrication of the machine tool;

3. Check whether the coolant in the coolant tank is enough, and it is not enough to add it in time;

4. Check the air pressure, loosen the adjustment knob, adjust the pressure according to the principle of right-turning to increase pressure and left-handing to reduce pressure, generally set to 5-7KG/CM2. The pressure switch is usually set to 5KG/CM2. When it is lower than 5KG/CM2, it will give an alarm. The system will give an "LOWAIRPRESSURE" alarm. After the pressure rises, the alarm message will disappear;

5. Check the oil level of the pneumatic triple-piece, which is about 2/3 of the height of the entire oil pipe, and discharge the water and gas in the pneumatic triple-piece oil filter tank through the drain switch.
