How CNC machines really work

The machining of metal parts must rely on machine tools, the “mother machine”, which, by cutting and grinding, can process regular metal materials into various shapes.

  In the traditional metalworking field, the manufacture of parts is the sparks of casting and forging welding and hard and fast turning, milling, grinding and pincer, we see any slightly shaped metal in our lives, before we see, have been in the factory to experience a number of iron and fire tempering.

Machine tools are the “mother machines” of other machines

Steel mills produce steel is not the strange shapes we see in life, but plates, tubes, ingots and other more regular shape of the material, these materials to be processed into various shapes of parts will need to use machine tools for cutting.

There are also some high precision requirements and surface roughness requirements of fine parts, we must use fine and complicated process on the machine tool to cut out or grinding out.

As with all machines, the initial machine tools include power units, transmission and execution devices, relying on the motor rotation input power, through the transmission device with the workpiece or tool being processed for relative movement, as to where the knife, cut how much, how fast speed cut and so on, it is controlled directly by the person in the process of processing.

Components of a general CNC machine tool

For general CNC machine tools, often contains a human-machine control interface, CNC system, servo drives, machine tools, detection devices, etc. The operator, with the help of some computer-aided manufacturing software, will be the various operations required for the machining process.

With the part program code, and through the human and control interface input to the CNC machine tool, after the CNC system for these information processing and computing, and according to the requirements of the part program control servo motor, to achieve the relative motion of the tool and the workpiece, in order to complete the processing of parts.
