NC servo feeder, what is the meaning of NC? NC English full name is numerical control Digital control is information in the form of digital code (program instructions). The servo control performs automatic servo feeding according to the given working program, movement speed and trajectory, referred to as NC servo feeder. The NC servo feeder has wide adaptability. When the feeding mode is changed, only the input program command needs to be changed. The machining performance is higher than that of the general automatic machine tool, and various models can be accurately used. Therefore, it is suitable for changing the input when the production specification object is changed. Program, digital instructions. NC feeding performance performance is higher than that of general automatic machine tools, accurate feeding, diversified servo feeding, linear automatic feeding, left and right yaw feeding, so it is suitable for high-precision mass production of various punches, and can obtain good production efficiency.

First, PLC is the core component of NC feeder
NC Feeder comes standard with Mitsubishi PLC, its built-in high-speed pulse output function, can directly issue a quantitative pulse number to control the servo drive operation. The servo driver controls the rotational position and speed of the servo motor according to the number of pulses and the channel emitted by the PLC pulse output terminal, thereby accurately giving the feed length. The touch screen can visually display and various parameters of the personality system, providing users with a good human-computer interaction interface and simplifying on-site operation.
When in the manual mode, the ACC (frequency acceleration/deceleration control) command is executed at the rising edge of the servo forward signal, and the mode control data is set to realize the CW (clockwise) direction rotation to make the servo motor rotate forward. At the falling edge of the servo forward signal, the INI (operation mode control) command is executed to stop the pulse output. The servo motor reversal can be analogized.
The control system of NC servo feeder is composed of PLC, servo system and touch screen imported from Japan. PLC is used to enhance the stability of the control system and enhance the anti-interference ability of the servo control system. The servo system can accurately determine the position of the mechanical movement and improve the mechanical feeding. Accuracy; the touch screen can visually display and change the parameters of the NC feeder to facilitate on-site operation.Precision Professional 18 production R & D suppliers, the company's feeders are classified into: NC feeder, servo feeder, punch feeder, NC left and right yaw feeder, high speed roller feeder, leveling feeder and other equipment

Second, the NC feeding machine feeding principle
NC feeder is also called servo feeder. It is an automatic mechanical machine that realizes accurate feeding and punching punching by the synchronous CNC pulley feeding roller through PLC, servo motor, servo drive and other complete CNC system. NC feeders are different according to the working structure. There are mainly two types of pneumatic NC feeders and mechanical NC feeders. The feeding principle of these two types of feeders is the same. The main difference is how to achieve relaxation.
