CNC routers are computer-controlled machines that are capable of cutting complex two-dimensional (2D) and three-dimensional (3D) shapes with router bits that spin at high speeds.
Edge finders are tools used to locate the edge of a workpiece during machine setup operations. Edge finders can be simple, mechanical tools, or electrically activated devices.
Lathes and turning centers cut a rotating part with a stationary cutting tool. The tool moves parallel and perpendicular to the workpiece axis to provide the desired finished shape.
Milling machines move a clamped workpiece into a fixed, rotating cutter; or move the cutter itself into a stationary workpiece. There are two basic configurations: vertical and horizontal.
