Look! This Power Save Master wire saw machine is quarrying and cutting stone. The Diamond Wire Saw quickly cuts a 1 - centimeter - wide gap in the stone. Its cutting speed reaches 20 square meters per hour. We can say that the cutting work is going very smoothly. However, there can also be setbacks. When the diamond wire saw gets stuck, the worker is trying to pull it to get it moving again, but it doesn't seem that easy. In this video, let's talk about the reasons and solutions when the diamond wire saw gets stuck during the cutting process of the wire saw machine. I'd like to make a solemn statement that there are many reasons and solutions. The relevant content mentioned in this video is for reference only. Due to my limited ability, I sincerely hope that experts can point out and supplement the deficiencies in the comments section.

Hello, everyone. I'm Oliver Mo, who manufactures and sells wire saws. There's a lot to talk about regarding this topic, so the video will be a bit long. This is a problem that many practitioners encounter during construction, so the video will be as detailed as possible.

(1) Problems with the beads themselves

Reason:  In recent years, the stone quarrying market has shrunk, and the competition in the diamond wire saw sales market has become fierce. To reduce costs, some manufacturers lower the grade of diamonds and use cheaper and harder matrixes when producing diamond wire saws. Diamonds are graded. Higher - grade diamonds have better grinding performance. If lower - grade diamonds are used, their grinding ability is weak. During the cutting process, the diamonds involved in cutting cannot perform the cutting and grinding work well, causing the beads to get stuck in the stone. The matrix is used to fix the diamonds. When the metal matrix is too hard and the material being cut is soft, the hard matrix is not easily worn out, and the diamonds are not easily exposed. Since the matrix itself has no cutting performance, the cutting will be difficult, and the beads will get stuck.

Solution:  It's very simple. Just purchase better diamond wire saws to replace the existing ones.

(2) Feed speed problem

Reason: If the feed speed is too fast, when the wire saw cuts into a hard - structured material, the cutting force decreases, but the feed speed still keeps applying pressure. Eventually, the beads will get stuck in the un - cut hard part.

Solution: Appropriately reduce the feed speed to make the cutting of the wire saw more stable and smooth, and avoid the beads getting stuck.

(3) Too fast starting speed

Reason:  At the beginning of sawing, there are sharp angles in the area to be cut. If the bending angle of the diamond wire saw is too small and the linear speed is too fast, the diamond wire saw is likely to get stuck.

Solution:  When starting the machine, keep the speed at 200 - 300 revolutions per minute. After cutting for 10 to 20 minutes, increase the cutting speed according to the cutting situation.

(4) Saw - slot cleaning problem

Reason:  If the saw - slot is not cleaned thoroughly, the crushed stones will jam the diamond wire saw. In addition, the stress extrusion of the ore body during the sawing process may also cause the diamond wire saw to get stuck.

Solution: Thoroughly clean the saw - slot and prevent other crushed stones from falling into it. During the sawing process, wedges can be inserted into the saw - slot to support the ore body and prevent the diamond wire saw from being stuck due to stress extrusion.

(5) Rope - joining problem

Reason: If new and old diamond wire saws are joined together for use and the diameter deviation between the ropes is too large, the diamond wire saw will be unevenly stressed during operation, which may easily cause the beads to get stuck.

Solution: Ensure that the diameters of the beads on the ropes are the same (or nearly the same) to guarantee the quality of the rope - joining.

(6) Cutting method problem

Reason: The cutting sequence for horizontal and vertical cutting is incorrect.

Solution: When the wire saw machine cuts a separated body, it must follow the principle of cutting the horizontal plane first and then the vertical plane. If it is for granite bottom - cutting, during the horizontal - plane cutting process, support wedges should be added to the saw - slot that has been cut in time to prevent local rock from falling and pressing the diamond wire saw, which may cause the diamond wire saw to be damaged and lead to accidents. If necessary, wedges can also be inserted into the vertical saw - slot to support the separated body.

(7) Multiple direction - changing problem

Reason: Due to the limitation of the construction site, the diamond wire saw needs to change direction using guide wheels. Each additional direction - change reduces the driving force of the diamond wire saw.

Solution: Try to reduce the number of direction - changes. When direction - changing cutting is required, use a wire saw machine with a larger power for cutting.

    In short, when the diamond wire saw gets stuck during the cutting process of the wire saw machine, the cause needs to be accurately judged according to the specific situation, and corresponding solutions should be taken. At the same time, in daily use, the operating regulations should be strictly followed, and the equipment should be well maintained to ensure the normal operation and cutting efficiency of the wire saw machine.
