    How to get ideal smoothness for medium wire cutting machine

    release time:2018-12-24  viewed:5308次
     The following measures will improve the finish to a certain extent:
    1. Decrease the pulse width and peak current appropriately, i.e. reduce the pit size.
    2. Guide wheels and bearings adhere to good accuracy and stability of operation, reduce silk shaking and jump, and minimize the silk track to adhere to one-line displacement.
    3. Molybdenum wire maintains appropriate tension, and adjusts the guide wheel and the input block, so that when the wire goes up and down, the tension in the working area remains unchanged.
    4. Silk should not be too tight, water should not be too fresh, fresh water is certainly beneficial to the cutting efficiency, but the cutting finish is not the best.
    5. A splint is added on the upper and lower sides of the over-thin workpiece, so that the commutation stripes are buffered within the scope of the splint.
    6. XY motion stability, accuracy, good follow-up fidelity, non-blocking crawling is also extremely important.
    7. Stick to stable and loose frequency conversion tracking.
    8. Re-cutting or repeated cutting with appropriate reserve will have beneficial effect on scale accuracy and smoothness if the cutting amount is very small. Three times of continuous sweeping will remove the reversing fringes fundamentally. As long as the machine tool has high repetitive positioning accuracy and the proper reserve is processed repeatedly, the smoothness of the cutting surface will be improved by one or two orders of magnitude. The effect is similar to that of slow-moving silk. The time-consuming is not too much. This is one of the advantages of the medium-speed wire cutting machine. Thicker workpiece can use short wire appropriately, the feed of one commutation is less than half the diameter of the wire, and the commutation stripe is also covered up.
