Reasons for the decrease of weaving efficiency of wire cutting machine

On the basis of wire cutting machine, add multiple cutting functions to reduce the running speed of molybdenum wire or install a gem wire guide. With these functions, the accuracy and surface brightness of cutting workpiece are improved compared with that of wire cutting machine in the early stage of use (the first two months). However, with the passage of time, the processing effect of wire cutting gradually weakened, so that later, many customers purchased wire cutting encountered the main problem.

The multiple cutting function of wire cutting machine makes the loss of molybdenum wire increase after processing the same area of the workpiece, which affects the accuracy and luminosity of the workpiece, and the vast majority of wire walking on the market is to extend the pulse power supply of wire cutting in the original wire walking. The pulse power supply can not adapt to the characteristics of multiple cutting in the middle wire.

wire cutting machine reduces the running speed of molybdenum wire, but also reduces the jitter in the process of molybdenum wire processing, which is helpful to improve the accuracy of the workpiece and surface brightness, but the real influence on the molybdenum wire jitter or the stability of the front guide wheel. Many users blindly believe that reducing the wire speed, multiple small current repair tool will bring high brightness, but it has been proved that once the service life of the guide wheel is over, the surface brightness of the workpiece processed after multiple cuts is not as good as the newly installed guide wheel wire cutting the surface of the workpiece.

wire cutting machine with gem wire guide, mainly draws on the guide structure of slow wire and punch machine, a common point of slow wire and punch machine is that the electrode wire and electrode travel slowly, but the first cutting wire speed of wire cutting in wire cutting is 40-60 times that of slow wire. The high-speed friction and high temperature generated in this process also make the gem wire guide on the slow wire walking and piercing machine not suitable for the requirements of the middle wire walking, which is very damaged and affects the processing effect.
