What are the basic knowledge to learn CNC milling machine? First, let's take a look at what we need to master in different directions.

1. Engaged in production: To learn CNC milling machine, CNC machining technology, CNC programming, CNC milling machine fault diagnosis and maintenance, mechanical drawing and mechanical manufacturing basis, these are some basic knowledge points that should be mastered.

2. Engaged in technician or design work: learn the basics of mechanical manufacturing and mechanical design.

What is a CNC milling machine?

Numerical Control: Numerical Control (Numerical Control, abbreviated as NC) is an automatic control technology that uses digital information to control the movement of a machine tool and its processing.

CNC milling machine is a kind of automatic processing equipment, which is developed on the basis of ordinary milling machine. CNC milling machine is controlled by computer digital signal. The processing technology and structure of the two are roughly the same.

What is the working principle of CNC milling machine?

CNC milling machine is to formulate the processing technology and processing parameters according to the technical requirements of the shape, accuracy, size and surface roughness of the processed parts. Through manual programming or automatic programming with software, the programmed processing program is input to the controller, and the controller will process it. After processing the processing program, it will send instructions to the servo. When the servo device sends a control signal to the servo motor, the spindle motor will rotate the tool, and the x, y, and z three-directional servo motors control the tool and the workpiece to move relative to each other according to the trajectory to realize the cutting of the workpiece.
