1. The blade if not used immediately, should be flat or by using the hole will hang up, lay flat on the blade can not be stacked, other items or foot, and to pay attention to moisture, rust.
When the blade is no longer sharp, cutting surface roughness, must be timely re grinding. Grinding can not change the original angle, and the destruction of dynamic balance.
3 blade diameter correction and positioning hole machining, must by the. If the processing is bad, will affect the product use effect, and the possible danger and reaming principle can not more than the original aperture 20mm, so as not to affect the balance of stress.
The choice of alloy wheel.
1) resin bond diamond grinding wheel with weak intensity, therefore grinding self sharpening can be good, is not easy to be blocked, high grinding efficiency, less grinding force, grinding temperature is low. The disadvantage is that the poor resistance to abrasion, abrasive loss, not suitable for the grinding of heavy load.
2) vitrified bond diamond grinding wheel wear resistance and binding ability is better than that of the resin binder, sharp cutting, high grinding efficiency, is not easy to generate heat and blockage, thermal expansion amount less, easy to control the accuracy, shortcomings and grinding surface of coarse, cost is higher.
3) metal bond diamond grinding wheel with high strength, good wear resistance, low wear, long life, low grinding cost, can bear larger load, but the sharp difference, easy to plug.
4) abrasive particle size of blocking and cutting volume of a grinding wheel has certain influence, coarse sand compared with fine sand, the depth of cut high abrasive cutting edge wear increases. On the contrary, the grinding wheel is easy to plug.
5) the hardness of grinding wheel has great influence on clogging, high heat conductivity coefficient of high hardness grinding wheel is not conducive to surface heat radiation, but it is beneficial to improve the machining precision and durability.
6) grinding wheel concentration selection is an important characteristic, which has a great influence on grinding efficiency and machining cost, the concentration is too low to affect the efficiency, whereas the abrasive grain is easy to fall off, but the best binder concentration range is also the best.
