1, brief introduction In honing, the selection of honing process parameters has a great influence on the accuracy, surface roughness, machining efficiency and service life of honing stone. 2. Honing working principle Honing is to process a precise surface by using the principle that three flat plates study each other. In grinding, honing the cutting surface of whetstone and the surface of the machined part are regarded as the process of mutual dressing of flat plates. 3. Dressing of honing whetstone Due to the manufacturing errors of honing whetstone, whetstone seat and grinding head body, it is impossible for the honing whetstone of the honing head to form a cylindrical surface after assembly, so as to ensure good contact between the honing whetstone and the machined surface. Although the honing whetstone can be trimmed together with the workpiece in the honing process, the grinding amount left by the workpiece is very small, so it is impossible to be fully trimmed in the initial honing process. In particular, honing whetstone with superhard abrasive can not be completely dressed because of its wear resistance. Therefore, it is impossible to obtain an ideal machined surface, and accuracy cannot be guaranteed. Therefore, when a new honing stone is used, it must be repaired (also called rounding) before processing. The dressing of ordinary honing whetstone is to put the honing whetstone directly on the grinding head used and take it to the cylindrical grinder for rounding, which is the most ideal. However, due to the structure of some grinding heads and other reasons, it is necessary to use special fixtures to dress the outer diameter of the cylindrical grinder with grinding wheels. If the precision of the honing workpiece is low and the honing head is floating, the rounding can also be corrected directly on the honing machine by using the waste work or the workpiece hole with large machining allowance. Dressing superhard honing whetstone with silicon carbide grinding wheel on cylindrical grinder. Grinding wheel speed 18-25m/s, grinding head speed 1-3m /min, feed depth generally 0.02-0.04mm/ stroke, and finish machining 0.0 1mm/ stroke. At the same time, a large amount of coolant is needed.
