What is CNC precision parts machining technology?

CNC stands for Computer Numerical Control and is a modern automation technology in the manufacturing industry that involves the use of a computerized control system to accurately control the movement and operation of a machine tool or machine tool for cutting, forming, 加工, or fabricating workpieces from materials. The core idea of this technology is to digitally program and control the movement of machinery to achieve high precision and efficiency in the machining process.

The main technologies of CNC machining

CNC machine tools:

These are mechanical devices used for machining workpieces, such as lathes, 铣床, drilling machines, grinding machines, and so on. These machines are equipped with control systems capable of receiving and executing computer-generated digital instructions.

CNC Programs:

Manufacturers use a specific CNC programming language (e.g. G-Code or M-Code) to create CNC programs. These programs contain information about tool movements, cutting parameters and workpiece dimensions.

Computer Control System:

This is the computer system used to run the CNC program. It controls the motion of the machine tool, usually using servo and stepper motors for highly accurate position control.

HMI:

The human-machine interface allows the operator to enter the CNC program, monitor the machining process, adjust parameters, and ensure proper operation of the machine.

Advantages of CNC machining technology

High Precision:

CNC machines are capable of achieving very high precision in machining mechanical parts, making them suitable for workpieces that require precise dimensions.

Automation:

CNC machines are able to automate multiple machining steps, reducing human error and increasing productivity.
