Machining is a process that creates finished products by cutting or drilling materials. CNC machining is an advanced form of machining that uses computer numerical control (CNC) equipment to automatize the production process. Many industries use this technology to produce parts for industrial machines, such as airplane engines and automobile engines
Spiral cutting is a machining process that involves rotating a tool in a helical path. The tool may have flat or round cutting edges and can be shaped in any number of configurations that make it possible to cut plastics, metals and other objects. There are many different types of spiral bits including those used when cutting wood, plastic materials, aluminum and stainless steel screws (hence the name spiral).
