FEWELL Professional Marble Diamond Saw Blades

Marble saw blade is a kind of cutting tool, which is widely used in the processing of hard and brittle materials such as concrete, refractory materials, stone, ceramics and so on. It is mainly composed of two parts; the base body and the segment. The base body is the main supporting part of the bonded segment, and the segment is the part that cuts during use. The segment will continue to be consumed during use, while the base body does not. The reason why the segment can cut The effect is because it contains diamond, which is the hardest substance at present, and it friction cuts the processed object in the segment. The diamond particles are wrapped in metal inside the segment.

Saw blade speed: In actual work, the linear speed of the marble saw blade is limited by the equipment conditions, the quality of the saw blade and the nature of the stone being cut. In terms of the best service life and cutting efficiency of the saw blade, the linear speed of the saw blade should be selected according to the properties of different stones. When sawing granite, the saw blade linear speed can be selected in the range of 25m ~ 35m/s. For granite with high quartz content and difficult to saw, the lower limit of the saw blade linear speed is appropriate. In the production of granite tiles, the diameter of the diamond circular saw blade used is small, and the linear speed can reach 35m/s.

Sawing depth: The cutting depth is an important parameter related to diamond wear, effective sawing, the force of the saw blade and the properties of the sawn stone. Generally speaking, when the linear speed of the diamond circular saw blade is high, a small cutting depth should be selected. From the current technology, the cutting depth of diamond can be selected between 1mm~10mm. Generally, when large-diameter saw blades are used to cut granite blocks, the cutting depth can be controlled between 1mm ~ 2mm, and the feed speed should be reduced at the same time.

When the linear speed of the diamond circular saw blade is large, a large cutting depth should be selected. However, when the sawing machine performance and tool strength are within the allowable range, a larger cutting concentration should be used for cutting to improve cutting efficiency. When there are requirements for the machined surface, small depth cutting should be used.

Feed speed: The feed speed is the feed speed of the sawn stone.

Its size affects the sawing rate, the force of the saw blade and the heat dissipation of the sawing area. Its value should be selected according to the nature of the stone being sawn. Generally speaking, when sawing softer stone, such as marble, the feed speed can be appropriately increased. If the feed speed is too low, it is more conducive to increase the sawing rate. For sawing fine-grained, relatively homogeneous granite, the feed speed can be appropriately increased. If the feed speed is too low, the diamond blade will be easily polished.

However, when sawing coarse-grained granite with uneven softness and hardness, the feed speed should be reduced, otherwise it will cause the saw blade to vibrate and cause the diamond to break and reduce the sawing rate. The feed speed of sawing granite is generally selected in the range of 9m ~ 12m/min. As the leader of the diamond tool industry, FEWELL Marble Saw Blade has been focusing on R&D and manufacturing the best sharp diamond saw blade in China for 27 years.
