Design Guide

Pro CNC has created a design guide which is a compilation of several of our past newsletters along with additional information to help engineers make smart choices when designing their CNC machined parts.  You can find the latest copy of the design guide here:

Raw Material Size Chart >>

This chart lists some of the most common sizes of material that are available in aluminum, stainless steels, brass and others.  Round bar, square bar, rectangular bar and plate are all covered.  By designing your parts to fit within the sizes shown here, you can save on the raw material costs for your CNC machined parts.

Pro Tips eNewsletter

One of our best engineering resources - our Pro Tips eNewsletter provides monthly design for manufacturability (DFM) advice. This real-world practical advice has been incorporated into our customer's designs, resulting in savings of thousands of dollars.
