During the sawing process of the stone cutting machine, the saw blade may be severely deflected, causing the equipment current to increase and cutting cannot continue. There are two reasons:
One is that the saw blade base deforms and produces deflection, which is mainly manifested by the excessively large slit width, which can be solved by correcting the base at this time;
Second, due to the friction between the saw blade base and the rock walls on both sides of the kerf, the kerf width is basically normal, the machineChina Stone Cutting Machine Wholesales runs normally during upper sawing, and the current value is normal. Does not reduce the feed concentration of the saw blade or the left and right walking speed.
In the second case, the use of cooling lubricant can effectively solve the problem. The cooling lubricant produces physical and chemical adsorption on the sawing interface (the substrate and the sawing surface of the rock), forming a thick lubricating film. The friction coefficient is as large as 0.38 or more; and if the cooling lubricant with a content of 0.2% is used, the friction coefficient can be immediately reduced to about 0.1. Even after using the cooling lubricant, the frictional resistance between the base and the rock wall can be reduced by more than 70%. As the cutting resistance is reduced, the receiving condition of the saw blade is improved. The deflection and vibration of the saw blade base body are controlled, thereby prolonging the service life of the saw blade.
