Welcome to CNC Router Parts!

Your number one resource for professional, industrial-grade
Ready-To-Assemble CNC Router and Plasma machines.

We offer complete machine kits, along with step-by-step assembly instructions, to enable you to build your own CNC cutting machines.

Our CNC machine designs combine commodity materials like steel and structural extrusion with innovative custom parts to provide our customers with affordable and expandable machines.

CNC Router Parts now offers three distinct lines of CNC machine components and kits.

Our Standard CNC line makes use of affordable components such as ACME lead screws and radial bearings to provide an exceptional value, and has a strong community of users worldwide.

Our PRO CNC line improves upon the performance of our standard line with upgraded components such as profile linear guides, precision ballscrews, and our PRO rack and pinion drive system.
We're pleased to announce the new PRO CNC 2016 Revision!

In addition to our machine kits and mechanical components for building CNC machines, we also carry two tiers of electronics to support different customer needs:

Our Nema 23 Electronics provide an affordable but very capable system for users less concerned with cutting speed, but who still want a reliable and easy to use system.

For production shops, commercial users, or those with very large machines, our Nema 34 Electronics packages offer increased power, greater speed, and higher depth of cut.

Both of our electronics systems are based around advanced all-digital motor drivers perfectly matched with our low-inductance motors, and feature integrated connectors and cables for secure, pluggable connections from drives to motors.
We've created a series of pictorial and video instructions in the Plans and How To's section for our more popular items, and a complete set of 3D viewable plans for our 4' x 4' and 4' x 8' kits. This information is free for viewing -- no special passwords or forum access is required. These are updated fairly frequently, so check back often for new content.
Check out what our customers have done with our parts in our Links and Build Logs section! This is by no means a complete list of machines people of have built with our components, but it does give a range of different builds that our customers have been kind enough to document. From smaller 2' x 3' machines up to 5' x 10' monsters, from stock plan builds to completely custom, you'll find dozens of examples of creativity and craftsmanship in this section, as well as links to build logs and other resources for the cnc machine builder.

Good luck with your CNC machine!
