Thermwood 3 Axis CNC routers handle plastic sheet processing, billets and panel processing (Model 43 and Model 45). Our 5 Axis CNC routers handle trimming of thermoformed parts, molds and composite machining (Model 67 and Model 90). We also offer the Model 70 and Model 77, which are primarily used for large scale plastic work.

Our machines can work with a wide variety of materials including Starboard, PCV, HDPE, Polyethylene, Polypropylene, PETE, LDPE, PP, PS (Styrofoam), Polycarbonate, Acrylic, Nylon and more.

Some of the basic tooling we use and recommend:

  • For Trimming Operations/Sheet Operations - Single O Flute Up-spiral is used for chip evacuation.
  • For Finishing – 2 or 3 Flute Slow Helix Up-spiral is used.
  • For Composites, we recommend solid PCD or diamond-coated tooling.
  • For Fiberglass Trimming, we recommend using a burr style bit for best results.

For more information, visit or give us a call at 1-812-937-4476. Our CNC experts will evaluate your production needs to help determine how you can reduce costs and increase efficiency. We also offer free live demonstrations of our equipment and software using your application and product details. This can help identify inefficiencies and areas of your current process that our machines could help improve.
