Factors affecting the efficiency of concrete saw blades

Concrete saw blade efficiency does not always remain the same, many factors will affect its cutting efficiency. Here are some of them.

Here is the content list:

l Sawing depth

l Into the knife speed

Saw blade line speed

In the actual work, the concrete cutting blade line speed by equipment conditions, the quality of the saw blade, and the nature of the stone to be cut by the limit. From the best saw blade life and sawing efficiency, should be based on the nature of different stones to choose the line speed of the saw blade. Sawing granite, saw blade line speed can be selected in the range of 25m ~ 35m / s. For high quartz content and difficult to saw granite, saw blade line speed to take the lower limit value is appropriate. In the production of granite face tiles, the use of concrete diamond blade diameter is small, the line speed can reach 35m / s.

Sawing depth

Sawing depth is an important parameter involving diamond wear, effective sawing, saw blade force, and the nature of the stone being sawed. Generally speaking, when the concrete diamond blade line speed is high, should choose a small cutting depth, from the current technology, sawing diamond depth can be selected between 1mm ~ 10mm. Usually, with a large diameter saw blade sawing granite barren material, sawing depth can be controlled in 1mm ~ 2mm between, at the same time should reduce the speed of the knife. When the linear speed of the concrete circular saw is larger, should choose a large depth of cut. But when in the saw machine performance and tool strength allowed range, should try to take a larger cutting concentration for cutting, to improve cutting efficiency. When there is a requirement for the processing surface, they should use a small depth of cut.

Into the knife speed

The feed speed is the feed speed of the sawn stone. Its size affects the sawing rate, saw blade force, and the heat dissipation of the sawing area. Its value should be selected according to the nature of the stone to be sawed. Generally speaking, sawing softer stone, such as marble, can be appropriate to improve the feed speed, if the feed speed is too low, more conducive to improving the sawing rate. Sawing fine grain structure, more homogeneous granite, can be appropriate to improve the speed of the knife, if the knife speed is too low, concrete saw blade edge is easy to be ground flat. But sawing coarse grain structure and soft and hard uneven granite should reduce the knife speed, otherwise will cause the saw blade vibration to lead to diamond shattering and reduce the sawing rate. Sawing granite into the knife speed is generally selected in the range of 9m ~ 12m / min.
