CNC machine tool is the abbreviation of Computer numerical control machine tools. It is an automatic machine tool equipped with a program control system. The control system can logically process the program specified by the control code or other symbolic instructions, decode it, express it with coded numbers, and input it into the numerical control device through the information carrier. After the arithmetic processing, various control signals are sent by the numerical control device to control the movement of the machine tool, and the parts are automatically processed according to the shape and size required by the drawing.

CNC machine tool solves the problem of complex, precise, small batch and multi-variety parts processing. It is a flexible and efficient automatic machine tool. It represents the development direction of modern machine tool control technology and is a typical mechanical and electrical integration. Chemical products.

Main Advantage

The operation and monitoring of the CNC machine tool are all completed in this CNC unit, which is the brain of the CNC machine tool. Compared with ordinary machine tools, CNC machine tools have the following characteristics:
1. Strong adaptability to the processing object and the characteristics of single-piece production of molds and other products, providing a suitable processing method for the manufacture of molds;
2. High processing accuracy and stable processing quality;
3. Multi-coordinate linkage can be performed, and parts with complex shapes can be processed;
4. When the processing parts change, generally only need to change the CNC program, which can save production preparation time;
5. The machine tool itself has high precision and rigidity, and can choose a favorable amount of processing and high productivity (generally 3 to 5 times that of ordinary machine tools);
6. The high degree of machine tool automation can reduce labor intensity;
7. Conducive to the modernization of production management. CNC machine tools use digital information and standard codes to process and transmit information, and use computer control methods, laying a foundation for the integration of computer-aided design, manufacturing and management;
8. Higher requirements for the quality of the operating personnel and higher technical requirements for the maintenance personnel;
9. High reliability.

CNC machine tool is an automatic machine tool equipped with a program control system, which can make the machine tool move and process parts according to the programmed program. It integrates the latest technology of machinery, automation, computer, measurement, microelectronics, etc., and uses a variety of sensors. The sensors used in CNC machine tools are mainly photoelectric encoders, linear gratings, proximity switches, temperature sensors, Hall sensors, current Sensors, voltage sensors, pressure sensors, liquid level sensors, resolvers, induction synchronizers, speed sensors, etc., are mainly used to detect position, linear and angular displacement, speed, pressure, temperature, etc.
1. The requirements of CNC machine tools for sensors
1) High reliability and strong anti-interference;
2) Meet the requirements of accuracy and speed;
3) Easy to use and maintain, suitable for the operating environment of the machine tool;
4) Low cost.
Different types of CNC machine tools have different requirements for sensors. Generally speaking, large machine tools require high speed response, and medium and high precision CNC machine tools mainly require accuracy.
2. Application of inductive synchronizer
Inductive synchronizers are made using the principle that the mutual inductance of two planar windings varies with position. Its function is to convert the angle or linear displacement into the phase or amplitude of the induced electromotive force, which can be used to measure the linear or angular displacement. According to its structure, it can be divided into linear type and rotary type. The linear induction synchronizer is composed of fixed length and sliding scale. The fixed length is installed on the machine bed. The sliding scale is installed on the moving parts and moves with the worktable. The stator of the rotary induction synchronizer is a fixed disk and rotor. For spinning discs. The induction synchronizer has the advantages of high precision and resolution, strong anti-interference ability, long service life, simple maintenance, long-distance displacement measurement, good manufacturability and low cost. Rotary induction synchronizers are widely used in turntables of machine tools and instruments and various rotary servo control systems.
