Knife Speed

The feed speed is the cutting speed of the 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 sawn stone. Generally speaking, sawing more soft stone, such as marble, can be appropriate to raise the speed of the knife, if the speed of the knife is too low, more conducive to improve the sawing rate. Sawing fine grain structure, the comparison homogeneous granite, may suitably raise the knife speed, if the knife speed is too low, the diamond blade is easy to grind flat. However, when sawing coarse-grained structure and soft and hard granite, the cutting speed should be lowered, or the saw blade vibration will cause diamond fragmentation and reduce the cutting rate. The cutting speed of sawing granite is generally selected within the 9m~12m/min range.
