  • Make it a habit to always check out the hydraulic pressure and see that it is set at 4.5 MPa. 
  • Check out also the hydraulic fluid and determine if they are just at the right level. 
  • Inspect your chuck pressure, this should always be at the right operating pressure. If you deem it is necessary to grease your chuck, always follow the manufacturer’s recommendation on this part.  
  • Replenish your lube level whenever needs, and see to it that your machine does have adequate amounts of it. 
  • If your CNC cutting machine for wood, steel, or for any material you may use it for, is equipped with its cooling mechanism, make sure that the cooling unit is always set at the right operating level. 
  • Make it a habit to clean and clear the chip pan of chips. 
  • Always practice cleaning the window of the door and light, this should help see what is inside your machine.  
  • You need to wipe clean your stainless steel way covers. Lubricating them with hydraulic is highly advised so they will move smoothly. 

At the lapse of 40 hours, get your filter out from the CNC control cabinet and thoroughly clean it. By this measure, you will optimize the air flowing through it which will help in cooling the machine down.  

Every Quarter of the Year
