What are the classifications of diamond saw blades in terms of appearance?

The appearance of the saw blade is closely related to its function. Some energy-saving, resource-based, and environmentally-friendly saw blade substrates are more and more popular in the market, and customers have new characteristics in the variety of saw blade substrates:

1. Thin and super thin saw blades Matrix

Thin and super thin saw blade substrates are mainly distinguished by the thickness of the substrate. For the ф1600mm substrate, the normal thickness is 7.3mm, the thickness below 6.5mm is called the thin substrate, and the thickness below 5.5mm is called ultra-thin. Film substrate. Using thin and super thin saw blade substrates to cut granite and marble slabs can greatly increase cutting efficiency and block yield, and reduce power consumption. For example, using a 4.0mm ф1600mm ultra-thin substrate with a thickness of 4.0mm can increase the cutting efficiency by more than 10% , Reduce power consumption by more than 20%, and increase the utilization rate of blocks by more than 16%.

Due to the thin thickness and large diameter of the thin and super thin diamond saw blade substrate, the deformation during heat treatment is relatively large, so the heat treatment process is very important for the control of flatness and HRC. At the same time, due to the thin thickness, it causes great difficulties in the adjustment of end jumps and stress, including detection. In general, it is difficult to achieve better results only by manual leveling and detection.

2. High efficiency frame saw blade Matrix

Diamond frame saw, also known as diamond saw, is a new type of frame saw machine developed in the 1950s. At present, in the developed countries of stone technology, the diamond frame saw frame has basically replaced the sand saw in the processing of marble. Its advantages are: fast cutting speed, high production efficiency; good processing quality, and the sawed plate is smooth and flat, which can be omitted A rough grinding process; save labor and steel, improve the labor environment, and facilitate management.

3. Super large saw blade base with a diameter of 2600mm or more

At present, the backward method of drilling and blasting is widely used in China to mine stone blocks. Not only is the production efficiency low, but the operation is unsafe, especially because the rock mass is broken due to blasting, and the stone resources are seriously damaged. The size of the blocks produced Irregular, even scrapped due to cracks, low yield rate. It is estimated that only 5% to 25% of the mining volume can be processed into timber by the method of drilling and blasting. Some developed countries in the stone industry have explicitly banned the use of explosive blasting methods to mine stone. The international industry believes that China’s stone mines have low productivity and serious waste of resources. The main reason is the lack of corresponding diamond saw blade substrates and the large amount of industrialization of related mechanized equipment. , Outdated mining technology, poor production management.

In addition, the market demand for large stone saw blades is increasing. In the past, frame saw blades were mainly used for processing stone slabs. However, diamond saw blade frame saw blades are mainly used for cutting soft stone such as marble. For granite and craft stone The cutting still needs a circular saw blade to complete. In order to meet the requirements of domestic and foreign markets, stone processing enterprises adopt super-large circular saw blades to cut large slabs, and there will be a peak in recent years.

4. Hollowed saw blade base

Compared with the conventional saw blade base, the hollowed-out saw blade base has only a few rows of holes processed on the base, and the shape of the holes is mainly a drop shape. Judging from the current use of фl600mm hollowed circular saw blades, the sawing process does not change any stone with a Mohs hardness below 7 degrees. Compared with the conventional one, the hollowed saw blade base has the following advantages. :

(1) It is easy to enter water, and the cooling effect is obviously improved;

(2) The chip removal rate is increased; 

(3) The weight of the substrate and the operating load of the sawing machine are reduced, and the current is reduced by 5A year-on-year; 

(4) The operating noise is reduced

(5) Due to the reduction of the weight of the base, it is possible for the small combination saw to load more diamond saw blades; 

(6) It can prolong the service life of the base, increase the number of square meters, and reduce the welding deformation; 

(7) Use intermittently and tension The recovery performance is good. A large amount of usage data shows that the use of hollow saw blade substrate to process stone can not only greatly reduce the power consumption per square meter, but also improve the utilization rate of stone block resources and increase the labor productivity of stone saw blade processing.

At present, hollowed-out saw blade substrates are not only widely used in the field of stone processing, but also in the field of stone mining, super-large hollowed-out saw blade substrates above ф2600mm have been increasingly popularized and used.

With the development of the stone industry carpet, the development of stone saw blades will also continue to advance in the footsteps of energy saving.
