The following are the routine maintenance items of horizontal machining center (as shown in Figure 1) in Dongguan CNC processing plant, including maintenance frequency, coolant capacity and type. In order to make the machine work normally and protect the warranty right, the user must comply with these necessary specifications.
1. Daily maintenance
Dongguan CNC processing plant should be filled with coolant every 8 hours (especially when the coolant of spindle center hole is used in large quantities)
. check the liquid level of guide rail lubricating oil tank.
. clean the iron filings on the rail guard and bottom plate.
. clean the scrap iron on the tool changer.
. clean the spindle taper hole with a clean cloth and apply clean oil.
2. Weekly maintenance
. check whether the automatic outlet of filter regulator works normally.
For the machine tool with spindle center hole cooling (TSC), clean the scrap collection basket on the cooling box.
. remove the cooling tank cover and remove the sediment. Pay attention to turn off the coolant pump and cut off the power supply of the numerical control system before handling the cooling box. Do this work once a month for machine tools without TSC.
. check that the barometer / regulator is 85 psi (0.6MPa)
. check the hydraulic balance pressure according to the machine specification.
. apply a small amount of grease to the outside edge of the manipulator of the tool changer, and replace all the tools with the manipulator.
3. Monthly maintenance
. check the oil level in the gearbox. Add the oil until it starts to drip out of the overflow pipe at the bottom of the waste oil tank.
. clean the pad at the bottom of the tray.
. clean the a-axis and the positioning pad on the feeding station. The tray needs to be removed for this operation.
. check whether the guide rail protective cover operates normally, and lubricate it with clean oil if necessary.
4. Every six months
Change the coolant and clean the cooling tank thoroughly.
. check all hoses and lubrication lines for cracks.
5. Every year
. change the gearbox lubricating oil. Drain the oil from the gearbox and slowly fill in 2 quarts (1.9 L) of Mobil DTE 25.
. check the lubricating oil filter and remove the residue at the bottom of the filter.
Replace the air filter on the control box every two years.
