While there are endless possibilities of what you can do with the ShopBot PRSalpha, here are a few examples of areas where people are putting their CNC tool to use:

Cabinet Making

With CNC, cabinetmakers can drill shelf pin holes, cut rabbets and dados, and profile-cut a completed panel. The operator only needs to handle the full sheet once to load the machine, and then remove the perfectly cut parts when complete.

Theaters and Museums

Realize your team’s aesthetic vision and go quickly from hand drawing to CAD design to full-size scenery panels. Complexity is easily incorporated when using CNC, so you can execute all kinds of ideas—including creating components in 3D.

Sign Making

Sign makers are using CNC for 3D carving, V-bit carving, profile contouring, fluting, and engraving. It also provides them with the opportunity to cut their own channel letter components, frames, posts, and borders in-house.

High-volume furniture and millwork companies, as well as novice and master craftsmen, are embracing CNC technology. Craftsmen are quickly realizing that the CNC process doesn’t jeopardize their pieces' authenticity; it only adds to quality and uniqueness of the finished product.

ShopBot offers accessories and add-ons for your tool. Here are a few of our most popular items.

Rotary Indexer

Rotary Indexer

Like a lathe, a rotary indexer provides a 4th rotary axis for turning a part, but it also provides precise “indexed” control over rotation.

Automaic Tool Changer

Automatic Tool Changer

An ATC reduces production time by automatically changing cutters during tool paths, allowing you to complete complex projects in a fraction of the time.
