Numerical control processing refers to processing with numerical control processing tools. CNC index-controlled machine tools are programmed and controlled by CNC machining languages, generally G codes. The CNC machining G code language informs which Cartesian azimuth coordinate of the machining tool of the CNC machine tool to choose, and controls the feed speed and spindle speed of the tool, as well as functions such as east-west converter and coolant.

The centrifugal force in CNC machining is proportional to the square of the speed to expand the oscillation caused by the imbalance. The resulting CNC machining intermediate oscillations during machining are added to minimize the life of bearing bushes, bearings, shafts, spindles and gears.

Before balancing the tools in the middle of CNC machining, it is necessary to measure the size of the imbalance and the orientation of each selected calibration plane. These variables are measured on two general types of balance machines: non-rotating or gravity machines are used to measure unbalance in a single plane, and rotating or centrifuges are used to measure unbalance in a single plane or two planes. Other methods for CNC machining components with subtle unbalanced quantities include adding solder to the component body or adding components to the pre-drilled holes. Regarding the tool, when you determine the imbalance you determine that it is necessary to remove the information to get the correct balance, the simplest and most useful way is drilling.

CNC machining skills are now widely promoted. Most machining workshops have CNC machining capabilities. The most common CNC machining methods in typical machining workshops are CNC milling, CNC lathe and CNC EDM wire cutting (electric discharge wire Cutting). What performs CNC milling is called CNC milling machine or CNC machining center. The lathe for CNC turning processing is called CNC turning center. CNC machining G code can be programmed manually, but the general machining workshop uses CAM (computer aided manufacturing) software to actively read CAD (computer aided design) files and generate G code programs to control CNC machine tools.
