About That CNC Guy

Welcome to That CNC Guy!

I’m Nathan, a CNC machinist and shop supervisor with a passion for precision manufacturing and helping others learn the trade.

I created That CNC Guy because machining can feel overwhelming when you’re first getting started. My goal is to break down complex topics into simple, practical explanations that anyone—from brand-new operators to experienced machinists—can understand and apply.

Here you’ll find articles on CNC machining, tooling, inspection, GD&T, shop tips, troubleshooting, and the skills that make great machinists. Everything is written from real-world experience on the shop floor, not just from a textbook.

Whether you’re trying to land your first machining job, improve your setup skills, or simply enjoy learning how parts are made, I hope this site helps you become a more confident machinist.

Thanks for stopping by, and welcome to the shop.
