Cutting parameters of diamond saw blade
Saw blade speed:
In practice, the linear speed of diamond circular saw blade is limited by the equipment conditions, the quality of the saw blade and the nature of the stone being sawed. In terms of the 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 linear speed of the saw blade can be selected within the range of 25m-35m / s. For granite with high quartz content and difficult to cut, the lower limit of the saw blade linear speed is appropriate. When producing granite tiles, the diameter of the diamond circular saw blade used is small, and the linear speed can reach 35m / s.
Sawing depth:
The sawing depth is an important parameter related to the diamond wear, effective sawing, the force of the saw blade and the properties of the stone to be sawed. Generally speaking, when the linear speed of the diamond circular saw blade is high, a small cutting depth should be selected. Technically, the cutting depth of the diamond can be selected between 1mm and 10mm. Generally, when the large-diameter saw blade is used to cut the granite block, the sawing depth can be controlled between 1mm and 2mm, and at the same time, the feeding speed should be reduced. 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, the cutting concentration should be as large as possible to improve the cutting efficiency. When the machining surface is required, small depth cutting shall be adopted.
Feed speed:
The feed speed is the feed speed of the sawing stone. Its size affects the sawing rate, the force on the saw blade and the heat dissipation in the sawing area. Its value shall be selected according to the nature of the sawn stone. Generally speaking, when sawing softer stones, such as marble, the feed speed can be appropriately increased. If the feed speed is too low, it is more conducive to improving the sawing rate. Sawing fine-grained and relatively homogeneous granite can appropriately increase the feed speed. If the feed speed is too low, the diamond edge is easy to be ground flat. However, when sawing granite with coarse grain structure and uneven hardness, the feed speed should be reduced, otherwise the saw blade vibration will cause the diamond to break and reduce the sawing rate. The feed speed of sawing granite is generally selected within the range of 9m-12m / min.
