Numerical control machining (CNC) refers to machining by a mechanic using numerical control equipment including machining centers, turn-milling centers, wire-cut electric discharge machines, screw thread cutting machines, and the like. Most machining workshops employ numerical control machining techniques. Through programming, the position coordinates (X, Y, Z) of the workpiece in a Cartesian coordinate system are converted into a program language, and a CNC controller of the numerical control machine controls the axis of the numerical control machine through identifying and interpreting the program language, so that the material is automatically removed according to the requirement, and the finished workpiece is obtained. Numerical control machining processes workpieces in a continuous manner, and is suitable for large-batch and complex-shape parts.
The existing machining mainly adopts a bench vice or an electromagnet platform to fix (adsorb) the lower end of a workpiece, and technicians can adjust and optimize the machining steps of the workpiece as much as possible according to different machining requirements of different workpieces in actual production so as to reduce the disassembly and assembly times of the workpiece, improve the efficiency and ensure the precision.
