Automatic saw blade grinding machine manufacturers teach you how to choose the grinding oil of the grinding machine
 
 
 
     Grinding is a finishing process, which requires high surface burns and strains. Therefore, the viscosity of the grinding oil is very important. The low lubricity is not enough to cause strain, and the high heat dissipation is not easy to cause burns. In the process of grinding, the instantaneous temperature of the oil can reach 130°C-140°C. Therefore, the oil has the characteristics of high flash point. Generally, the flash point of the grinding oil is not less than 160°C, and the process is instantaneous. Excessive temperature will produce oil smoke, oil mist will cause certain harm to workers, especially in a sealed, constant temperature processing environment, although grinding oil can not completely eliminate the generation of smoke, but additives can be used to suppress the generation of smoke. To reduce the harm to workers.
 
    The average grinding wheel speed of the worm is about 3000 rpm. The requirement for high smoke is higher than that of the forming, and the flash point should be above 170. This can reduce the generation of smoke, and at the same time, the extreme pressure requirement is high, and the relative grinding oil viscosity can be slightly higher. ~5, because the speed is fast, if the lubricity is not good, it may cause strain and burn. If the viscosity is too large, the heat dissipation of the machine will cause local burns. Therefore, the worm gear grinding machine should choose 40 °C viscosity of 14 Between ~16, grinding oil with flash point ≥ 175 or higher containing no sulfur chlorine molecules.

Full-automatic saw blade grinding machine factory talks about the grinding of alloy sawtooth
 
(1) The use of a precision, stable vibration-free sharpening machine, as well as a suitable diamond grinding wheel, to repair the alloy serrations according to the specified operating procedures will extend the life of the saw blade. If you use a manual sharpening device, you need to have a precise limit device and detect the end jump of the tooth tip.
 
(2) The resin, debris and other debris adhering to the saw blade must be cleaned with a cleaning agent before grinding.
 
(3) When the saw blade grinding machine is sharpened, it is necessary to strictly follow the original geometric design of the saw blade. It is recommended to use the sharpening method of the rake angle and the back angle at the same time, which can increase the number of grinding times. Achieve a long service life of zui.
