CNC is a machining process in which a pre-programmed software feeds directions to tools and machinery to create products. Because CNC machining is so effective, it’s used in a range of industries and processes. CNC can control grinders, lathes, mills, and more. CNC plastic machining allows three dimensional cutting tasks to be done in a single set of prompts. For that reason, it’s preferred for more complex parts. Manual machining requires that an operator be there to guide the machine. With CNC plastic machining, there is no longer the need for the extra labor; it can complete tasks automatically.
