1. Daily maintenance of ordinary lathes

The daily maintenance of the lathe can keep its accuracy as new

Before class:
1. Wipe the dust on the exposed guideway surface and sliding surface of the machine tool and add oil;
2. Lubricate all parts according to regulations;
3. Check the position of each handle;
4. Test run with empty car.

In the class:
1. Strictly abide by the operating procedures;
2. Pay attention to the operation of the machine at any time during operation, and deal with abnormalities in time.

After class:

6. Pay attention to check the tightness of the guide rail and adjust the gap;
7. Pay attention to check whether there is abnormal noise from the oil pump of the oil tank of the hydraulic system of the machine tool, whether the height of the working oil level is appropriate, whether the pressure gauge indicates normal, and whether the pipelines and joints are leaking;
8. Pay attention to check whether the guide rails and machine tool guards are complete and effective;
9. Pay attention to check the mechanical accuracy of each moving part to reduce the deviation of shape and position;
10. Do a good job of cleaning the machine tool every day after get off work, clean the iron filings, and wipe the coolant on the static rails to prevent the rails from rusting.

3, the daily maintenance of vertical lathes
Daily maintenance content and requirements:

Responsible person: the operator performs the inspection, and the inspection staff inspects.

Before work:
First, check the handover notepad;
Second, refuel in strict accordance with the equipment “lubrication chart” to achieve timing, quantification, and quality;
Third, for equipment that has been shut down for more than 8 hours, when the equipment is not started, the machine should be rotated for 3-5 minutes first to confirm whether the lubrication system is unblocked and all parts are operating normally before starting to work.

A. Always check the operation of each part of the equipment and the working condition of the lubrication system. If there is an abnormal situation, immediately notify the inspection staff to deal with it;
