Maintain Your CNC For Optimum Results

Want better results from your CNC machine?  It’s easy – take care of it.  It doesn’t matter which brand of CNC you have, a regular schedule of maintenance is important to keeping it running.  I know many buyers have purchased machines already assembled.  If this is the case and you didn’t assemble it yourself, find videos on maintaining or assembling your machine so you have a better understanding of how it works and what can go wrong.CNC Configuration

Here are a few simple steps you can take to show your machine some love:


Just like changing the oil in your vehicle, your machine needs lubrication to keep it from wearing out.  That’s why each machine should be regularly inspected and the proper lubrication applied as needed. Using the wrong grease or oil could cause serious problems, so adhere to the manufacturer’s recommendations.

Keeping It Clean

When possible use dust collection.  You and your machine will be healthier.  Dust and particles have a way of getting into rollers, gears and belt teeth.  Either way you should plan of cleaning your machine on a regular basis.

Follow Manufacturer’s Maintenance Schedule.

Again, just like your vehicles, each machine has a preferred schedule of when you should show your machine some attention.  Your machine will last longer between breakdowns – which you will have at some point.

Don’t Neglect Peripherals. 

Your CNC machine likely has a number of accessories – from clamps, dust collectors and on some coolant systems – which should be included in your regular maintenance program. A system is only as strong as its weakest link and an out-of-alignment fixture, clogged hoses or a clogged coolant nozzle can lead to costly downtime.

Keep Critical Spare Parts On Hand. 

Having a backup of normal wear-and-tear items on hand can save you time. It is likely you will be in the middle of a job when you really need a part.  Things like belts, router brushes and spare end mills or router bits should be close by for when not if you need them.


A little common sense will go a long way in keeping your machine running smoothly.  Just a few minutes a day will save you hours and dollars in the long run.
