The precision CNC machining system is different from the general grinder, especially the workpiece does not rotate, the grinding motion and the circular cutting motion are completed by the revolution and rotation of the grinding head, and the up and down cutting motion is completed by the up and down strokes of the grinding head sleeve. The grinding head is a component that performs the main motion of coordinate grinder grinding motion. There are two kinds of grinding heads: high frequency electric grinding head and air turbine grinding head.
At present, precision CNC machining is to achieve high-precision machining that cannot be achieved by the existing ordinary precision machining methods. In terms of its quantity, it is to process the shape and size of submicron or even nanometer scale and obtain the surface roughness of nanometer scale. However, how much precision value can be counted as ultra precision machining depends on the size, complexity and easy deformation of parts.
