After the operation, the numerical control device sends out various control signals to control the action of the machine tool, and automatically processes the parts according to the shape and size required by the drawings.
Numerical control machine tool solves the processing problem of complex, precise, small batch and multi-variety parts. It is a flexible and efficient automatic machine tool, which represents the development direction of modern machine tool control technology and is a typical mechatronics product.
Extended data:
I. Main features
1, which has strong adaptability to processing objects, adapts to the characteristics of single-piece production of products such as molds, and provides suitable processing methods for mold manufacturing.
2. The machining accuracy is high and the machining quality is stable.
3, multi-coordinate linkage can be carried out to process parts with complex shapes.
4, processing parts change, generally only need to change the numerical control program, can save production preparation time.
5. The machine tool itself has high accuracy and rigidity, and can choose favorable processing dosage and high productivity (generally 3~5 times that of ordinary machine tools).
Second, the technology application
Numerical control machine tool is an automatic machine tool with a program control system, which can make the machine tool move and process parts according to the programmed program. It combines the latest technologies such as machinery, automation, computer, measurement and microelectronics, and uses a variety of sensors.
Sensors used in CNC machine tools mainly include photoelectric encoder, linear grating, proximity switch, temperature sensor, Hall sensor, current sensor, voltage sensor, pressure sensor, liquid level sensor, resolver, inductosyn and speed sensor. , mainly used to detect position, linear displacement, angular displacement, speed, pressure, temperature, etc.
