CNC Milling

Cer-Mac Inc. is a turn-key machine shop with an expert CNC milling team that works with many CNC milling machines to produce CNC milled parts that meet your needs. Our team is fully equipped to service your CNC milling and 5-axis machining needs.


What sets Cer-Mac Inc. apart from other CNC milling and turning facilities is our 5-axis milling capabilities. Our 5-axis milling centers are the cornerstones of our CNC milling department.

Extensive CNC Machining Services

Our CNC milling process starts by working directly with you to learn more about what parts you need to be produced. We know about your manufacturing needs, how many parts you need to be machined, what features you may require, and if you need any special final surface finishes. After programming, we choose a CNC milling machine that makes sense for the machining process.


These CNC milling service options include 5-axis milling, high spindle milling, and 3-axis CNC milling. After we find the CNC milling process that suits you, we’ll program our CNC milling machine to cut high-quality parts that meet your particular specifications. If your project calls for 5-axis machining, we can handle that as well.


Our computer-controlled milling process includes specifications like +/- 0.001-inch tolerances, and the ability to machine a 36-inch cube. We can also do plate work on pieces up to 80 to 120 inches, drill holes as small as 0.005 inches, and provide thread milling capability.
