CNC machining refers to the processing that the control system issues commands to make the tool perform various movements that meet the requirements, and express the shape and size of the workpiece in the form of numbers and letters. It generally refers to the process of machining parts on CNC machine tools. CNC machine tools have the following four characteristics:
1. Process concentration
CNC machine tools generally have tool holders and tool magazines that can automatically change tools. The tool changing process is automatically controlled by the program, so the process is relatively concentrated. Process concentration brings huge economic benefits.
2. Automation
When
CNC machine tools are processed, there is no need to manually control the tool, and the degree of automation is high.
3. High flexibility
Traditional general-purpose machine tools have good flexibility, but low efficiency; and traditional special machines, although high in efficiency, have poor adaptability to parts, high rigidity and poor flexibility, making it difficult to adapt to the fierce competition in the market economy. Products are frequently modified. As long as the program is changed, new parts can be processed on the
CNC machine tools, and the operation can be automated, with good flexibility and high efficiency, so the CNC machine tools can well adapt to market competition.
4. Strong ability
Machine tools can accurately machine various contours, and some contours cannot be machined on ordinary machine tools.
CNC machine tools are especially suitable for the following occasions: parts that are not allowed to be scrapped, new product development, and processing of urgently needed parts.
