Mid speed wire cutting machine is a device that uses stepper motors to control the precise linear motion of workpieces, commonly found in various precision machining equipment. Here are several key points of its working principle:
1. Stepper motor:
A stepper motor is an electric motor that converts electrical pulse signals into angular displacement or linear displacement. It can rotate in a fixed number of steps, with each pulse signal corresponding to a step angle, meaning that each time a pulse signal is received, the motor rotates a fixed angle.
2. Control system:
Stepper wire feeding is usually composed of a computer numerical control system or a dedicated stepper motor controller, which controls the motion speed, direction, and processing path of the wire feeding mechanism through input commands and parameters.
3. Wire moving mechanism:
The wire moving mechanism is the core part of wire moving in steps, including guide rails, guide wheels, and driving devices. The guide rail is used to support and guide the movement of the workpiece. The guide wheel maintains the contact between the workpiece and the guide rail, while the driving device provides power to push the wire feeding mechanism to drive the workpiece to perform linear motion.
4. Wire cutting tool:
Wire cutting tool is a key tool for performing machining tasks, usually made of hard alloy, with excellent cutting performance and wear resistance.
5. Electronic development:
The stepper motor generates a rotatable magnetic field inside, and when the rotating magnetic field switches sequentially, the rotor will rotate by the corresponding angle. This design allows the stepper motor to rotate at a known angle without losing step, thereby achieving precise control of the motor's position.
6. Torque frequency characteristics:
The torque output of a stepper motor varies at different operating speeds. Normally, the faster the operating speed, the smaller the output torque, otherwise it may lead to step loss. Each specification of stepper motor has its specific torque frequency characteristic curve.
The structure and composition of the mid speed wire cutting machine are complex and precise, and each part cooperates with each other to achieve high-precision and high-efficiency cutting functions.
