The difference between sandwich segment and grove segment

The diamond segment appeared along with the diamond saw blade. The earliest diamond segment appeared in France at the end of the eighteenth century. At that time, it was discovered that the sharpness and grinding ability of the saw blade can be improved by sintering diamond and metal. At that time, artificial diamond products were immature, so all saw blades were made of natural diamond, which was extremely expensive. By the middle of the 19th century, through continuous efforts in research and development, artificial diamonds gradually matured, and diamond segments slowly appeared in people's lives.

At that time, the diamond segment was one-piece. In the 20th century, people found that the one-piece segment had a long life, but its sharpness was unsatisfactory. Especially in order to control the manufacturing cost of the segment, people wanted to find a high sharpness but a higher diamond concentration. Low products, thereby reducing production costs and forming a product competitive advantage. At this time, multi-layer diamond segments are slowly being developed, such as sandwich segment and grove segment. What is the difference between these two segments? Mainly reflected in the following aspects:



The structure is different: the sandwich segment, as the name suggests, uses a three-layer structure, with agglomerates on both sides and a section in the middle. The grove segment is different. In addition to the three-layer structure, it can also be five-layer, seven-layer, nine-layer, and eleven-layer. In addition to such an odd-numbered layer structure, it can even be designed as an even-numbered grove structure segment.

The second difference is that it has different uses: sandwich segments will be used for marble cutting, while grove segments will be used for mining, granite and marble block cutting, and mid-diameter saw blade segments are used for cutting large slabs and standard boards.

The third difference is the use and composition of each layer of agglomerates: For sandwich segments, the layers on both sides and the middle layer are the main cutting layers. Among them, the agglomerations on the left and right sides are made of relatively large granularity.

The diamond with a higher fine grade is used in the middle, and the diamond with larger particles but lower grade is used. The middle part mainly plays a role of fast breaking and accelerating the cutting, while the diamonds on both sides can maintain the life of the segment, so Such segment life is very good. However, the multi-layer segment is divided into a working layer and a non-working layer. The working layer and the non-working layer are superimposed layer by layer. The non-working layer does not contain any diamonds or iron sheets, and does not have cutting performance, so such a segment The life is relatively low, but because the cutting surface is convex, it has a great advantage in sharpness, so it is very suitable for cutting harder stone.



Fourth: The overall shape is different: the sandwich segment is generally a rectangular parallelepiped shape, and the upper and lower dimensions are uniform, while the grove segment can be the uniform specification of the upper and lower specifications, or can be made into a trapezoidal tetrahedron shape, and there are more choices in terms of modeling.

In summary, I believe everyone should know the difference between sandwich segment and grove segment. At present, sandwich segments are mainly used for marble processing in Turkey and nearby areas, while grove segments have been distributed in stone factories in various regions of the world, and their uses are even more varied. widely.
