After using the CNC lathe for a period of time, wear occurs between the two parts in contact with each other, and its working performance is gradually affected. At this time, some parts of the CNC lathe should be properly adjusted and maintained to restore the lathe to its normal technical state. . The daily maintenance and first-level maintenance of the CNC lathe are completed by the operator, and the second-level maintenance is jointly performed by the operator and the maintenance staff. The maintenance cycle and the time of each maintenance should also be based on the structure and coarseness of the CNC lathe. Different processing conditions are reasonably determined, and often adjusted according to the actual situation.
1. Daily maintenance and maintenance of CNC lathes
CNC lathe operators should perform corresponding maintenance and maintenance on CNC lathes daily.
1) Check whether the oil quantity of each oil tank of the lubrication mechanism is normal, and turn on to check whether the lubrication system can operate normally.
2) Check whether the oil quantity of each oil tank of the hydraulic mechanism is normal, and turn on to check whether the hydraulic system can operate normally.
3) Check whether the amount of cutting fluid in the cooling tank is normal. Turn on and check whether the cutting fluid system can operate normally.
4) Turn on the machine to check whether the CNC system is normal, whether each fan chip remover is operating normally, and whether the pressure gauge values are normal.
5) Clear the iron filings and debris in the guide rails of the CNC lathe, and check whether there are scratches on the surface.
6) After the machine is turned on, it must be idling for a certain period of time to check whether it is operating normally. After completing the one-day processing task, turn off the CNC system of the CNC lathe, turn off the power of the lathe, and clean up the work place.
2. First-level maintenance of CNC lathes
1) Wipe the exterior of the CNC lathe, including covers, covers, and accessories, to ensure that there is no oil, rust, corrosion, iron filings, and debris, and to ensure that the interior and exterior are clean.
2) Clean the iron filings on the rotary tool post and tailstock and check whether they are operating normally.
3) Check whether there are loose screws on the lathe, and whether the fuel tanks, pipelines, and connectors are firmly connected, and if there is any repair in time.
4) Check the wear and tension of the spindle drive belt, X-axis drive belt, and Z-axis drive belt.
5) Check whether the hydraulic system and its components (hydraulic pump, hydraulic motor) are operating normally, and whether there are abnormal noises during operation.
6) Check whether the cooling system and its components (cooling pump, cooling motor) are operating normally, and whether there are abnormal noises during operation.
7) Check whether the chip removal system and its components (chip remover, chip removal motor) are operating normally, and whether there are abnormal noises during operation.
8) Check whether the lubrication system is operating normally to ensure that the oil circuits are unblocked, check and replace the filters as needed; check whether the oil outlets are normal to lubricate the machine tool (rails, tailstock).
9) Check all fuel tanks and cooling water tanks, and replenish them as required. Fill the machine with oil and grease as needed to ensure that the fuel tanks, oil gauges, and oil windows are bright. Add rust inhibitor to cutting fluid according to requirements in summer.
10) Check whether the CNC system is normal after starting, and whether the movement of each axis of the CNC lathe and the rotary tool post is normal.
11) Wipe the electrical box to ensure that the inside and outside are clean, check whether each line is leaking, whether the contacts are in good contact, and check whether the limit device and ground are safe and reliable.
CNC lathe combines electricity, machine and fluid in one, has the characteristics of technology-intensive and knowledge-intensive, and is a kind of advanced processing equipment with high degree of automation, complicated structure and expensive. In order to give full play to its benefits and reduce the occurrence of failures, maintenance must be done. Therefore, CNC lathe maintenance personnel are required to have not only mechanical, processing technology and hydraulic and pneumatic knowledge, but also electronic computers, automatic control, drive and measurement Knowledge such as technology can fully understand and control the CNC lathe, and do a good job of maintenance in time.
