Materials we can machine, cut or engrave using our CNC router.

Materials We Cut And Engrave

There is a huge variety of materials out there that can be machined using a CNC router, but I will be covering the materials that we CNC cut or engrave on a regular basis.

The four main material categories we commonly machine are wood, plastic, resin board and aluminium.


WOOD

I will start with wood as it is certainly the most common material to CNC machine.  There are literally hundreds of woods out there but the most popular types for CNC routing are the engineered woods pictured below.

All of the above are great to work with, although the glue used to manufacture these woods can cause excessive tool wear and problems.


PLASTICS

As with wood, there simply are so many different types to mention.  I will again focus on what we predominantly use.

Perspex/Acrylic

In sheet form Poly(methyl methacrylate) (PMMA) it is a transparent thermoplastic.

Aluminium

Aluminium is an exceptional material to CNC machine.
