CNC routing machines using conventional techniques

1. Winding machine for precision winding, mostly realized in the low speed, for some thick lines, it is necessary to start the spindle at a low speed to have a larger torque output. Spindle reversible operation requires the flexibility to run forward and reverse, in the actual winding, with the different requirements of customers, at any time may adjust the spindle rotation direction, forward or reverse rotation to achieve, while the change in the direction of rotation requirements, there should be a greater backlash and loss of strenuous exercise.

2. The direct use of real-time digital signal control and accurate; the use of servo systems and Winder static characteristics and dynamic performance index is superior reflects the superiority of the servo system. System depends on the resolution string rate system performance and stability of the entire winding machine and the position detection element is used.

3. After mechanical transmission, also called the servo system has excellent static and dynamic load characteristics, when the winding condition occurs, the servo system under different load conditions or changes in the spindle running speed should be kept constant. Because NC Winder servo system proposed stringent technical requirements, servo system also comes with a dedicated execution of its servo motors made stringent requirements:

4. Whether winding machine running at the lowest speed or in the most high-speed, servo motors are capable stable operation, low torque ripple, especially at very low speed, you should still have a steady pace without creeping phenomenon.

5 .servo motor should be able to withstand frequent starting and braking and reverse. Servo motor overload capacity islarge should be a longer period of time, to meet the needs oflow speed and high torque requirements, general DC servo motor used in some special roving winding machinerequirements overload within minutes 2 to 4 times without damage. 

6 in order to meet the requirement of quick response of winding machine control system, servo motor should besmall moments of inertia and large torque, and is as small as possible time constant and the starting voltage, should generally be ability with larger acceleration tolerance, in order to ensure the servo motor starting from rest to rated speed within 1 second.
