CNC Machine Preventative Maintenance 


Preventative maintenance should be something that is done regularly to avoid any problems that may occur in the future, and is a great way to know the ins and outs of second hand machinery. Downtime is something that costs you both time and money in a production based environment, but these steps must be taken to keep your machine running in tip top shape. You want to take daily, monthly, and yearly preventative maintenance measures to make sure your machine is performing at its peak an producing the best possible products possible. We’ve broken out what steps you can take to ensure the best possible performing machine.


Daily maintenance would include checking things such as hydraulic fluid, and maintaining 4.5 MPa for hydraulic pressure. You want to also make sure chuck pressure is operating at the correct pressure, and make sure the cooling system is optimized at the right level as well. If any chips have accumulated on the chip pan, you’ll want to clean those out and apply grease to anything it needs to be applied to. The chip conveyer chain should be checked and greased every three months, as well as the filters should be changed on the coolant tank. Every six months should include cleaning the coolant tank of any excess chips and sludge that may accumulate, and the jaws and chuck cleaned as well. Fresh hydraulic fluid should replace the old fluid after it is completely flushed and drained from the system, as well as the cooling fluid. For yearly maintenance you should check the headstock, spindle, and chuck cylinder for wear and tear and replace as needed. The X and Z axis gibs should be checked and adjusted accordingly as well. 


Taking these necessary preventative steps can keep your machine running at its best, and keeping your production line in full swing. is your source for used machinery auctions on the West Coast, and we strive to help our customers pick the best machine for their needs.
