Pushing table saw ruler manufacturers remind the correct operation of log push table saw blade is equal to improving use efficiencyThe operation of each part of the push table saw is important, so how to operate the log push table saw blade correctly? The push table saw depends on the ruler The main points are as follows: 1. If the saw blade is not used immediately, it should be placed flat or suspended using the inner hole. No other items or foot steps can be stacked on the flat saw blade, and attention should be paid to preventing moisture and rust. 2. When the saw blade is no longer sharp and the cutting surface is rough, it must be re-grinded in time. Grinding can not change the original angle, and destroy the dynamic balance. 3. The inner diameter correction and positioning hole processing of the saw blade must be carried out by the manufacturer. If the processing is not good, it will affect the use effect of the product and may be dangerous. In principle, the reaming hole should not exceed the original diameter of 20mm, so as not to affect the balance of stress. 4. Selection of alloy grinding wheel. 1) The bonding strength of the resin bond diamond grinding wheel is weak, so the self-sharpness during grinding can be good, it is not easy to be blocked, the grinding efficiency is high, the grinding force is low, and the grinding temperature is low. Large, not suitable for heavy-duty grinding. 2) Ceramic bond diamond grinding wheel has better wear resistance and bonding ability than resin bond, sharp cutting, high grinding efficiency, not easy to generate heat and blockage, less thermal expansion, easy to control the accuracy, and disadvantages of rough grinding surface and high cost . 3) The metal bond diamond grinding wheel has high bonding strength, good wear resistance, low wear, long life, low grinding cost, and can withstand large loads, but it has poor sharpness and is easy to block. 4) The abrasive particle size has a certain influence on the clogging of the grinding wheel and the cutting amount. Compared with the fine grit, the coarse grit has a larger cutting depth and the cutting edge wear of the abrasive grain increases, otherwise the grinding wheel is easy to block. 5) The hardness of the grinding wheel has a great influence on the blockage. The high hardness of the grinding wheel has a high thermal conductivity, which is not conducive to surface heat dissipation, but is conducive to improving the machining accuracy and durability. 6) The selection of grinding wheel concentration is an important feature, which has a great influence on grinding efficiency and processing cost. Too low concentration will affect the efficiency. On the contrary, the abrasive grains are easy to fall off, but the optimal binder concentration range is also the best. |
