Why is the "brain" of CNC servo system machining center 1370?
Why is the servo system called the brain of a processing center:
The execution part and mechanical transmission part of the CNC machining center constitute the feed system of the CNC machine tool, which controls the feed speed, direction and displacement of the execution part according to the speed and displacement instructions sent by the CNC device. The execution parts of each feed motion are equipped with a servo system. The function of the servo system is to convert the pulse signal from the numerical control device into the movement of the moving parts of the machine tool, which is equivalent to the hand of a manual operator, so that the worktable (or slide) can be accurately positioned or strictly relative to the specified trajectory. Finally, the parts that meet the requirements of the drawing are processed. Therefore, the servo system is also called the brain of the small processing center. The formal servo system directs the moving parts of the machine tool to complete mechanical movements such as displacement and rotation.
How the brain of the processing center directs the movement of the mechanical part:
The servo system of the machining center is composed of a servo drive motor and a servo drive device, which is the execution part of the numerical control system. The drive components that drive the motion of the CNC machine tool actuator include spindle drive unit (mainly speed control), feed drive unit (mainly speed control and position control), spindle motor and feed motor, etc. Generally speaking, the servo drive system of a CNC machine tool requires a good fast response performance, as well as a function that can track commands sensitively and accurately. The servo systems of CNC machine tools include stepping motor servo systems, DC servo systems and AC servo systems. The latter two are commonly used now, both with position detection components such as inductosyn and encoders. AC servo systems are replacing DC servos. System.
The "brain" technology of the processing center continues to improve and the technology continues to mature:
In recent years, servo motor control technology has developed more and more rapidly, and it is developing in three directions: communication, digitization, and intelligence. As the actuator of CNC machine tools, the servo system integrates power electronic devices, control, drive and protection. With the advancement of digital pulse width modulation technology, special motor material technology, microelectronic technology and modern control technology, it has experienced From stepping to DC, and then to the development process of AC.
