Blade Maintenance:
1. If the saw blade is not used immediately, it should be placed flat or hung with an inner hole. No other items and feet should be stacked on the flat saw blade, and attention should be paid to moisture-proof and rust-proof.
2. When the saw blade is no longer sharp and the cutting surface is rough, it must be repaired and ground in time. Grinding can not change the original angle, and destroy the dynamic balance.
3. The correction of the inner diameter of the saw blade and the processing of positioning holes 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 original diameter should not exceed 20mm, so as not to affect the stress balance.
4. Selection of alloy grinding wheel.
(1) The resin bond diamond grinding wheel has weak bonding strength, good self-sharpening during grinding, not easy to block, high grinding efficiency, low grinding force and low grinding temperature. Suitable for heavy duty grinding.
(2) The wear resistance and bonding ability of vitrified bond diamond grinding wheel are better than that of resin bond, sharp cutting, high grinding efficiency, not easy to heat and block, less thermal expansion, easy to control the accuracy, the disadvantage is that the grinding surface is rough and the cost is high.
(3) The metal bond diamond grinding wheel has high bonding strength, good wear resistance, low wear, long service life, low grinding cost and large load, 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 amount of cutting. Compared with fine sand, the cutting depth of coarse sand is larger, and the wear of the cutting edge is increased. On the contrary, the grinding wheel is easy to be blocked.
(5) The hardness of the grinding wheel has a great influence on the blockage. The high hardness and high thermal conductivity are not conducive to surface heat dissipation, but are conducive to improving the machining accuracy and durability.
(6) The choice of grinding wheel concentration is an important feature, which has a great influence on grinding efficiency and processing cost. If the concentration is too low, it will affect the efficiency. Conversely, abrasive particles tend to fall off, but the optimal bond concentration range is also optimal.
