Advantages and technical difficulties of diamond wire cutting machine

Compared with the traditional "blasting + flame cutting" mining method, diamond wire cutting machine has the following advantages in mining granite:

1. Wide adaptability, diamond wire cutting machine is suitable for all types of mines, while flame cutting is only suitable for granite mines with high quartz content and few cracks.
2. Strong function, high efficiency, first mining depth, can reach l0-20m or even deeper, flame cutting generally only within 10m; secondly cutting speed, generally can reach 3-4m 2/h, is 2-3 times the flame cutting.
3. The diamond wire cutting machine can cut vertically, horizontally and obliquely, and can also cut blindly, while the flame cutting can only cut vertically.
4. High yield and low comprehensive cost. First, the cutting surface of diamond wire cutting machine is very smooth and will not cause any internal injury to the waste material. Second, the sawing seam is small, only about 11 mm, which will not cause waste of resources; while the flame cutting surface is rough and uneven, and causes a certain internal injury to the waste material, and the sawing seam is large, generally 100-300 mm, causing a lot of money. The source is wasteful and the cost of exploitation is high.
5. Safety and environmental protection, diamond wire cutting machine mining noise and dust-free, does not affect nearby residents and other working areas, and high degree of automation, separate control, low labor intensity, high safety; and flame cutting noise and dust are very large, seriously affecting the work of residents and other workers nearby, and workers labor intensity, safety Sex is relatively low. To sum up, in today's increasingly scarce resources and soaring oil prices, wire saw mining granite has significant economic and social benefits.
Various factors associated with diamond diamond wire cutting machine include: sawing life of beads, sawing speed of beads, spacing of beads on diamond wire cutting machine, die design, life of wire rope under normal working conditions and other technical difficulties.
The most common problem
1. The most common thing that rope saw can not saw and use is incorrect selection of diamond (usually too good diamond), matrix, bead spacing, mold design or wrong application parameters. For example, if we choose diamond with too high density or too good diamond, its sawing performance is not very good. Diamond will not break easily, so it is difficult to produce new sharp blade tips.
2. Saw rope breakage, usually using the wrong application parameters or the poor quality of the saw rope, which means that plastic/rubber and diamond beads are not firmly bonded, resulting in rock debris into the diamond saw rope, soon magma or rock debris in bead steel and wire rope in part contact and friction between wire rope, wire rope connection thread This may be due to the incorrect use of binding agents. The breakage of the steel rope may also be due to the incorrect selection of the steel rope, Beaded steel, and poor heat treatment after injection molding.
3. If the beads are peeled off from the beads, it is usually improper to choose the matrix or to use the wrong sintering parameters. The incorrect cold pressing process is usually the cause of spalling. Sometimes it may also be due to improper wax removal process, so that the metal matrix and bead steel infiltrated into paraffin wax. Sometimes this problem is also related to improper cleaning of bead steel.
4, the combination of string beads and loose bead
