A stone quarrying worker contacted me and said that the wire saw machine they're using can't achieve a high cutting speed. At first, they thought it was because the Diamond Wire Saw wasn't sharp enough. So, they bought several types of diamond wire saws from different manufacturers for testing, but the result was still not satisfactory. Today, we've come to this quarry to find out the reason.

Hello, everyone. I'm Oliver Mo, who manufactures and sells wire saws. It's correct that they first considered the diamond wire saw when they felt the cutting efficiency of the wire saw machine was not high enough. After ruling out the sharpness of the diamond wire saw, we need to look at their cutting method. When cutting a mountain, large - area cutting is usually carried out. Even if you're using a high - power 75KW machine for cutting, due to the large area and the long contact surface where friction occurs, the cutting speed will never be fast. If the combined mining mode of a circular saw and a wire saw is adopted, when the wire saw machine is used for undercutting, the principle of cutting the narrow side instead of the long side should also be followed to keep the cutting speed at a relatively high level. So, today we'll focus our observation on dressing, because small - area cutting can avoid the problem of improper cutting methods. However, the moment I got close to their wire saw machine, I already found the answer. The slow cutting speed of their machine is neither the problem of the diamond wire saw nor the cutting method, but the problem of the machine itself, because the machine head of their machine has sagged significantly! You can clearly see from the connection between the machine head and the machine body that the gap is wider at the top and narrower at the bottom, which means the machine head has sagged. When the machine head sags, the machine head will shake during the cutting process of the wire saw machine. Originally, it could cut vertically and smoothly downwards, but due to the shaking, the diamond wire saw also cuts while swinging, which seriously affects the cutting efficiency.

In the wire saw machine industry, the key is to prevent the power head from sagging and shaking. Our factory's engineers tried many ways to overcome this problem and finally came up with a great solution. The engineers installed a reducer and a slewing box inside the machine body, and a bearing outside the machine body. Finally, they installed the motor at the position of the machine head. A large number of actual test data show that the double - supported slewing reducer has successfully overcome the problem of the sagging power head of the wire saw machine and has obtained a national patent. So, I have to give an advertisement here. If you want to buy a wire saw machine, I highly recommend our factory's Power Save Master. The power head doesn't sag, and the cutting speed is guaranteed.

Finally, I'm Oliver Mo, who manufactures and sells wire saws. I hope to be your partner on the stone quarrying journey. If you encounter any problems when buying a wire saw, you can contact me privately. See you in the next video.
