Computer numerical controlled (CNC) machines are tools that use programmed commands to execute intricate woodworking processes more efficiently than handheld machines. A CNC machine works on the Cartesian coordinate system and offers 3D motion control to the machine operator. The operator begins by typing measurements into a CAD-based program. Next, the machine uses those measurements to automatically execute necessary cuts. CNC woodworking machines were once a luxury for owners of woodworking shops but today shop owners can find a used CNC router for sale, or any other CNC machine, for less than half the cost of a new machine.
CNC routers are especially desirable because they automatically perform difficult cuts that handheld routers have difficulty completing without any errors. These machines rout or hollow out a section of a wooden sheet. One is most likely to see a router being used in the cabinetry trade, but many other jobs require a groove to be drilled. Given that these CNC woodworking machines offer multi-functionality, quick set-up, and ease of use, woodworking shops have made it a priority to add these machines to their fleet cnc grooving machine.
To demonstrate how CNC woodworking machines are better than handheld machines, consider how several frequent router jobs differ when completed with a handheld machine instead of with a CNC machine.
When using a handheld router, one performs edge routing by moving the router counterclockwise after clamping down the wood sheet. The counterclockwise motion is necessary because it makes the machine easier for the operator to control, but even when using this motion the wood is still susceptible to chipping. Edge routing by moving counterclockwise can especially cause chipping around the corners while burns occur when the operator moves the machine too quickly. Chipping and burning caused by operator error is eliminated when the operator uses CNC woodworking machines, as they move automatically and eliminate the chance of operator error.
“Dado” is a term used to describe a small groove that has been cut into the surface of a wood sheet. Dadoes are commonly seen on bookshelves, as these grooves allow shelves to be affixed to the wooden frame. Typically a woodworker using a handheld router will need a straight bit and a jig in order to create these holes. The process of creating dadoes will call for the woodworking professional to drill holes of varying measurements into a test piece of wood before drilling on the work piece. This lengthy process is needed to prevent mistakes, but when a woodworking shop finds a used CNC router for sale and purchases it, the shop can complete this process more quickly. Since CNC woodworking machines complete all cuts automatically, the operator can drill on the work piece without having to measure and re-measure.
Along with completing edge routing and dadoes using inputted measurements, CNC woodworking machines also eliminate the need for patterns because they automatically perform precise cuts. Woodworking shops that wish to perform routing and other processes more efficiently should find a vendor with a CNC router for sale.
