CNC machine tools (Numerical Control Machine Tool, referred to as CNC) are machine tools that can automatically complete various processing operations according to pre-programmed instructions. According to the drawings of the processed parts, process analysis is carried out, and the processing program is written. The processing program is input into the CNC device to complete the trajectory interpolation operation, control the motion trajectory of the machine tool actuator, and process the workpiece that meets the requirements of the part drawing. The CNC system completes the storage and processing of a lot of information, and transmits the processing results of the information to the subsequent servo motor in the form of control signals. The working effect of these control signals depends on two core technologies: one is the interpolation operation of curves and surfaces, and the other is the motion control of the multi-axis of the machine tool.
- Common types:
-CNC lathe: used for cutting of rotating workpieces, which can realize turning, boring, tapping and other operations.
-CNC milling machine: used for plane, surface and thread processing on the workpiece, and can perform end milling, vertical milling and other operations.
-CNC grinder: used for high-precision grinding of workpieces, such as surface grinding, cylindrical grinding, etc.
-CNC cutting machine: used for shearing, cutting or engraving of metal and non-metal materials, such as laser cutting machine, plasma cutting machine, etc. - Advantages:
-High precision: Due to the use of digital control, higher processing accuracy and stability can be achieved.
-High efficiency: Automated operation and fast cutting speed enable CNC machine tools to greatly improve production efficiency.
-Powerful ability: Multi-axis control and multi-functional processing can be performed to achieve more complex processing technology.
-Good repeatability: Through pre-programming, the same processing tasks can be accurately repeated to ensure the stability of product quality.
-Shortened processing cycle: It can perform automated processing of multiple processes at the same time, shortening the entire processing cycle. - Application areas:
Widely used in various manufacturing industries, including automobiles, electronics, energy, etc. They are used to process various metal and non-metal materials, such as iron, aluminum, steel, plastic, etc., to produce various parts, molds, tools and other products.
