How do I maintain my CNC milling machine?

Maintenance of CNC milling machines is quick and easy. If carried out regularly, you will improve execution, reduce spontaneous downtime and increase the general life of the machine. Following the maintenance rules laid down by the manufacturer will further enable you to pursue and perform customary protection support undertakings on your machine.

Here are five general maintenance guidelines to keep the different parts of the CNC milling machine up-to-date and working effectively:

1. Regular cleaning and maintenance: CNC milling machines are ideally suited for heavy industrial applications and as such, they need to be cleaned properly on a daily basis. This helps to avoid any form of chips or fluids being absorbed into the controls and bearings. Power supplies must be adequately, accurately and safely connected in accordance with local power control regulations.

2. Vacuum pumps: Vacuum pumps and control boxes have air filters which need to be changed regularly. The largest machines require pneumatic air to work. It should be spotlessly clean, dry and kept relentlessly above 6 bar or 80 PSI. 3.

3. Connectors: By turning off the machine you will reduce the risk of burning out the connectors. This will allow your machine, and its user, to be properly secured from sudden power surges.

4. Other machine components: Pumps, bearings and oscillating vanes need to be properly and correctly lubricated. Normally, lubrication should be a monthly affair. Deep clean the leadscrew and ball nut fixtures with WD40. Damaged or worn cap nuts, collets and tools can affect the quality of the cut. Therefore, check for broken parts in the machine and replace these every 3 to 6 months. Ensure that the belt is replaced every two years.

5. All 3-axis gears: The gear assemblies of the fourth and fifth axes must be properly cleaned and properly greased. Also, adjust the backlash on each shaft.
