1. Hydraulic system
numerical control machine hydraulic pump should be selected variable pump, in order to reduce the hydraulic system heating tank installed in the filter, should be regularly used or ultrasonic vibration cleaning. Common failures are pump body wear, cracks and mechanical damage, at this time generally must be repaired or replaced parts.
2. Air pressure system
The numerical control machine pressure system used for tool or workpiece clamping, the safety protection door switch and the chip discharge pressure system of the spindle cone hole, and the water filter should be regularly added and cleaned to ensure the sensitivity of the pneumatic components in the moving parts. Spool action failure, air leakage, pneumatic component damage and action failure and other failures are caused by poor lubrication, so it is necessary to regularly clean up the oil mist. In addition, the tightness of the pneumatic system should be checked frequently.
3. Lubrication system
numerical control machinecnc lubrication system includes lubrication of machine guide rail, transmission gear, ball screw, headstock, etc. The filter in the lubrication pump needs to be cleaned and replaced regularly, and replaced once a year.
4. Cooling system
numerical control machine cooling system Its effect on tool and workpiece cooling and chips. Coolant nozzle should be cleaned regularly.
5. Chip removal device
The chip removal device of the numerical control machine is an independent function of the attachment, mainly to ensure the smooth progress of automatic cutting and reduce the heat of the numerical control machine. Therefore, the chip removal device should be able to automatically remove chips in time, and its installation position should be as close as possible to the cutting area of the tool.
