Keep your CENTROID running in top condition for years to come! Replacement parts and repair for older systems not listed on the web site is available

The industry's most affordable replacement parts are available for every servo based Centroid CNC control ever made. Centroid designs and manufactures its own CNC CPU's, axis motor amplifiers, and machine tool PLC's, ensuring parts are always in stock if you should need them. With a Centroid CNC you'll be able to keep your machine running for many years to come. A Centroid CNC control has been designed for up-time! Centroid has combined uncommon reliability with affordable CNC replacement parts, simple control maintenance, and upgrades that will keep your CNC machine making chips!

To minimize machine downtime, swapout components are on the shelf ready for fast delivery, here is how it works.
Call Tech Support 814 353 9256 (press 4). Get an RMA #.
We send you a replacement component right away, you send back the faulty component- OR- You send us faulty component we repair and send back to you the same repaired component.
Core charges and core policies apply to swapout components that are drop shipped.
Typical core charges range in the $250-$500 depending on component.
You have two weeks to return the Core to receive the core charge credit, 30 days return for International customers.
There are no core charges if you request that we repair and return the original part.

- If you send us a component and we evaluate it and you decide not to repair it or swap it out there is a minimum evaluation charge of $250.
- If the time to repair the component is lower than the fixed repair cost, the repair cost will be the lower of the two with a minimum repair charge of $450
- Sometimes swap out components are not available, in that case there are two choices,
   1.) Repair existing component 2.) Buy a new replacement component
