Corian is a solid surface material that is composed of approximately one-third acrylic resin (PMMA) and two-thirds natural minerals, primarily alumina trihydrate (ATH) derived from bauxite ore. In addition to these primary ingredients, Corian may also contain trace elements of iron oxide black, carbon black, titanium dioxide, colorants, and methyl methacrylate.

Because of this intense material makeup, people are often unsure how to cut Corian material or question whether or not their CNC router can cut it. The short answer to this question is that your CNC machine can absolutely cut Corian and cut it well. When you pair the correct endmill and feeds/speeds, this material cuts like butter!

For this test cut, we used The Legacy a Specialty Cutting Systems 4′ X 8′ CNC router with it’s stock 12 HP spindle, max 24,000 RPM. This machine offers more than enough power and speed to cut solid surface material.

The Legacy router has an automatic tool change but all we needed here was one tool. Depending on the Corian thickness and design, you can choose the Razor Series tool diameter that fits your needs. In this case, we cut 1/2″ Corian with a 1/4″ 3 Flute Spiral Upcut endmill called “XR2062-CB” This tool is meant to cut fast without sacrificing quality and it did just that.

We set this tool up to cut the part out at 300 IPM, 22,000 RPM, Climb Cut, and 2 passes. The edge quality came out great and there was little to no sound while this material was being cut. The Razor series bits were invented to cut Corian and we have yet to find an endmill that does it better. If you have some solid surface to cut, give us a call and find out with of the Razor series bits we would recommend as well as the specific feeds/speeds that would work best for your machine.
