What is the difference between CNC milling machine and conventional milling machine?


CNC milling, or computer numerical control milling, is a machining process that employs computerized controls and rotating multipoint cutting tools to progressively remove material from the workpiece and produce a custom-designed part or product. This process is suitable for machining a wide range of materials, such as metal, plastic, glass, and wood, and producing a variety of custom-designed parts and products. A conventional milling machine, also called a manual milling machine, is a machine that can manufacture all kinds of parts. The table feed is manually controlled by an operator. Do you know the difference between CNC milling machine and conventional milling machine?
  1. CNC milling machines generally have a CRT screen display function, displaying processing procedures, multiple process parameters, processing time, tool motion trajectory, and workpiece graphics. It also has an automatic alarm display function. According to the alarm signal, the operator quickly finds the machine malfunctioning. And conventional milling machines do not have the above functions.
  2. The main transmission and feed transmission of the CNC milling machine adopt DC or AC -level speed regulating servo motor. Generally, there is no spindle gearbox and a feed gearbox, and the transmission chain is short. The main driving and feed transmission of conventional milling machines generally use three-phase AC asynchronous motors. The gearboxes can be used to achieve multi-level transmission to meet the process requirements. The machine tool transmission chain is long.
  3. CNC milling machines generally have a workpiece measurement system, and the workpiece size is generally not required during processing. Conventional milling machines must be continuously measured manually to ensure the processing accuracy of the workpiece.
  4. The most significant difference between CNC milling machines and conventional milling machines is that when the workpiece changes, the CNC milling machine only needs to change the processing program, and there is no need to make a large adjustment to the machine tool, that is, a variety of different workpieces can be processed.
