Digital control machine tool, commonly known as CNC machine tool; It is an automated machine tool that uses system programming and other programs to control. The biggest difference between this type of machine tool and ordinary machine tools is that as long as the program is set up, the machine tool can operate on its own without the need for manual operation.
Secondly, CNC machine tools have a wide range of applicability, requiring only corresponding changes to different program instructions for processing different workpieces; Compared to ordinary machine tools, CNC machine tools have higher flexibility and accuracy. Mechanized program processing makes CNC machine tools more suitable for batch processing of medium and small high-precision parts, achieving higher economic benefits.
The composition of a CNC machine tool includes mechanical components such as the bed, column, spindle, and worktable. These mechanical components are precisely moved and positioned through the control of CNC devices, thereby achieving various cutting processes. The driving device of a CNC machine tool includes a spindle drive unit, a feed unit, a spindle motor, and a feed motor. Under the control of the CNC device, the driving device achieves spindle and feed drive through an electrical or electro-hydraulic servo system. When several feedbacks are linked, it is possible to complete the machining of positioning, straight lines, planar curves, and spatial curves. Of course, some CNC machine tools can also replace the five axis head, cradle five axis, and rotary table for auxiliary processing, achieving twice the result with half the effort.
CNC machine tools have the characteristics of high machining accuracy, multi coordinate linkage, complex machining shapes, saving production preparation time, high productivity, and high degree of automation. In addition, there are various types of CNC machine tools, such as CNC milling machines, CNC lathes, CNC grinding machines, etc., which can be selected according to different processing needs.
