Is Your CNC Machine Down? Here’s What You Can Do!



It’s your worst nightmare when running your CNC machine. You’re chugging along, happy with your productivity. Maybe even excited because you know you’re going to have something to good to show your boss. And then your machine stops doing anything.

Or, maybe your CNC machine didn’t even start up in the first place. It happens because even the best CNC machinery eventually breaks down. Nothing’s perfect.

So what could be going on? Without being there, we can’t say. But, we can give you some ideas of what to do so you can save time and get back up and running fast:

Set Up a Good Maintenance Schedule in the First Place

Okay, so if your CNC machine has already broke down, this doesn’t do you any good. However, it’s a must if you don’t already have a regular maintenance routine in place because it eliminates most future breakdowns. The best way to do it is to create a baseline of all your alignments and write down all the numbers you have when your CNC machine makes a good part.

You should check your machine frequently afterwards. Base your check on how much you use your machine, whether your shop floor has settled at all, and if your CNC machine’s had a little abuse from an accident or two around your shop.

Don’t Check Your Software First! Do This Instead…

For CNC machinists, checking the software is the natural first urge. Don’t do it! You’ll only drive yourself crazy as you wander around in logistical circles.

In most cases, the real cause of your problem will be your geometric alignments. So check all those first.

Common Causes of CNC Machine Failure

The most common reasons your CNC machine fails are because of two things present in abundant quantities in nearly every CNC machining environment: heat and contaminants. Lubricants, cutting fluids, scrap metal shavings, dirt, oil, and dust can be found everywhere.

Top this off with the fact that most production floors run hot, and you have the perfect recipe for CNC machine failure at some point. Yes, the cabinets are outfitted with AC. But, your AC can get clogged with all those contaminants we talked about before.


Your routine maintenance plan needs to address these issues so you stay up and running efficiently over the long haul.
