Why the price of gang saw segments are so expensive

The gang saw segment is a diamond tool used for gang saw blade. It is mainly used for the processing of marble, especially for the stone with a large slab area, the gang saw is a good choice. During the use of the gang saw, there is friction between the segment part and the stone, and the stone and the segments are worn. However, due to the hardness of the gang saw segment, the wear is much smaller than that of the marble. In the long-term processing process, the gang saw will be complete the cutting process of the stone according to the set cutting speed.

When buying a gang saw segment, many customers will find that compared with the marble segment of a circular saw blade, the volume of the gang saw segment is very small. Not only has the length been shortened, but the width has also been greatly reduced, but inquiries When it comes to the price, it turns out that the price of a gang saw segment is much higher than that of a marble segment. So why is the price of gang saw segments so expensive? This article explains this question from the customer.



1: The matrix composition of the gang saw segment is different. Because the structure of the gang saw segment and other segments are composed of two parts: diamond and matrix bond, the size of the gang saw segment is relatively small, but in order to maintain the service life , The hardness of the matrix binder must be increased, otherwise, the segment will be consumed very quickly, which will shorten the life, and the expensive welding cost is very high, so the gang saw segment must to use cobalt powder with better hardness as the basic metal alloy material. Simply say, a diamond segment with more cobalt powder, then the price will be more higher. Because the price of cobalt powder is relatively expensive. A large amount of cobalt powder naturally causes the price of gang saw segment to be high.

2: The sharpness of the gang saw segment is more demanding. Although it is cutting marble, but the gang saw segment is welded to the flexible saw segment, this kind of saw segment is very flexible, especially the ultra-thin gang saw segment. The thickness of the saw segment is only a few millimeters. The segments welded on such a saw segment must be very sharp, otherwise the gang saw will be offset, twisted, etc., and the board will be damaged. However, we mentioned above that the gang saw segment requires a long life. The second point is to cut fast. Therefore, the comprehensive improvement of both factors will naturally cause the gang saw segment to use better raw materials, and the price will be higher.

3: A lot of abrasive resistant materials are added to the gang saw segment. Since the gang saw segment adopts a reciprocating cutting process, the gang saw segment in the middle part is always inside the block and is always involved in cutting. If the segment is not resistant Grinding, the two sides of the segment will be smoothed quickly, which will cause the cutter to jam and the cooling fan will not heat well, which will cause the stone processing to be blocked. The worse situation is that the segment is dropped, the board is broken and so on.



4: The gang saw segment is better welded, because the gang saw segment needs to face great impact in the process of cutting the stone, but the gang saw has a smaller welding surface, and naturally, the impact force will form greater stress. If the welding surface is insufficient, it is very easy for the segment to fall off. In order to perform welding better, it is necessary to maintain the welding area during the high-frequency welding process.

5: The diamond grade of the gang saw segment is higher. The volume of the gang saw segment is small. It needs to use better raw materials to achieve greater cutting performance. Almost ordinary marble segments use low-grade diamond powder. However, the diamond gang saw segment uses relatively high-grade diamond powder, and the price of raw materials is higher, which naturally leads to more expensive gang saw segments.

The price of diamond gang saw segments is generally about twice that of ordinary segments. Although the size is small, the grinding, speed, and life are greatly improved. Although such segments increase the processing cost, but they save stone, reduce waste and pollution.
