How to use the diamond segment.

Diamond segment is a kind of stone processing tool, mainly according to the actual use of the segment, it is divided into the segment for mining, the segment for block cutting, the segment for crushing stone, the segment for trimming, the segment for metal abrasives, Grinding wheel segments and drill bits for drilling, etc., These segments are used in different ways. Let's take a look at them in detail:

Mining segment: This kind of segment is mainly used for mining, and is welded on the saw blades of different sizes used in the double-blade circular saw in the mine.

Among them, the large saw blade is welded with a segment with a smaller thickness, while the small saw blade is welded with a segment with a larger thickness. First use a small saw blade for grooving, and then use a large saw blade for cutting. The usage of mine segment is:

1: Build a welding platform and fix the semi-automatic high-frequency welding machine.

2: Welding by semi-automatic high-frequency welding.

3: After the segment cools down naturally, check the welding firmness of the segment.

4: The saw blade is returned to the position by the hoist, waiting for installation to cut.



Block cutting heads: There are many types of block cutting segments, such as sand saw segments for traditional granite cutting, gang saw segments for frame saws for marble cutting, and single-piece gantry cutting segments. Single-blade saw segments, as well as combined segments for different blank blade thicknesses. The specific welding methods of these segments are not exactly the same, especially in the welding process of sand saw and gang saw segment, most of them are semi-automatic welding by gang saw segment manufacturers. Welding is carried out by gang saw welding machinery, but there are also a small number of stone factories that buy fixtures and perform flame welding. However, because flame welding relies too much on the proficiency of personnel, it is difficult to promote.

Most of the welding of other circular saw blade segments will also use semi-automatic welding machines. Similar to the construction of the welding table for the segment in the mine, working on the top of the saw blade, through high-frequency welding, during the process of rapidly heating the segment and rapidly cooling down, the solder firmly welds the base body and the segment together. However, it should be noted that during the welding process of the segment, overheating will cause the welding process to fail, so interval welding is the most common welding method.

The welding of the splitting segment and the trimming segment is a very common welding method for the splitting segment and the trimming segment. For saw blades with a diameter of 550-850mm for the splitting segment, the size of the saw blade is not large, while the diameter of the saw blade used for the edge trimming segment is mostly 250-500mm. These saw blades can currently be completed by fully automatic welding machines, of course, semi-automatic welding machines can also be used.

The metal abrasive segment and the grinding wheel segment are both types of abrasive segments. The main fixing method is mainly the flame spray gun. The main reason is that this type of abrasive requires a lot of segment specifications, and it is impossible to produce fixtures corresponding to them one by one, so fire welding is also the most cost-effective welding method. But for some commonly used grinding discs, automatic welding may become a reality in the future.



The welding of drill bits has gradually changed from fire welding to a semi-automatic process. At present, there are a large number of semi-automatic welding equipment for drill bits, which can meet the welding of large-sized hollow core bits.

In terms of specific use, if high-frequency welding or flame welding is used to fix the diamond segment, it needs to be used in an environment with water. And pay attention to the initial process of the segment not cutting edge, use slow speed, less depth of cut setting to slowly make the segment edge, and then adjust the self-speed and increase the cutting depth, so that the segment can cut more freely.
