The last thing you want to encounter when you’re in the middle of an important production run is a machine malfunction. This can happen any time, with any machine, regardless of how much money it cost. Reasons for this can be anything from improper operator training, to using the wrong type of tools or not keeping your maintenance log up to date.

When your maintenance log is kept up-to-date, your machine will be fine-tuned and running smoothly every day. In the event a technical issue arises, an up-to-date log also helps technicians troubleshoot the issue much faster.

Here’s a list of some of the more common daily and monthly maintenance tasks you need to do to keep your CNC machine running smoothly all year round.

Daily tasks
Every day you should do the following:

1. General Cleaning: include these steps:
Move the gantry to the back of the machine.
Blow off the table surface and X axes towards the front of the table.
Blow off the gantry away from carriage.
Blow down behind the Z plate.

2. Air Pressure Reading: Record the air pressure reading indicated on the gauge.

3. Oil Oscillating Knife: Oil the oscillating knife (1-2 drops, every 4 hours).

4. Check Pump Oil Level: Check the pump oil level through the sight glass on the pump.
 
5. Clean Cover nuts and Collets: Clean (blow) the cover nuts threads and collets when changing the tools.
