Title How to grind the surface of the grinding wheel
Description High quality 9'' grinding wheel plays a role in grinding. The grinding wheel should pay attention to many problems when grinding. For example, pay attention to the height of the grinding wheel axis and the workpiece axis. When the grinding wheel is polished, there are skills and precautions. What is the specific content? When high quality 9'' grinding wheel, the grinding wheel can usually judge the contour height according to the grinding pattern. The surface of the grinding ball is convex, and the lower half of the surface grinding wheel is used for grinding. At this time, the center position of the grinding wheel should be adjusted to make it The center of the workpiece is contoured until it is cross-webbed by the surface of the sphere. When high quality 9'' grinding wheel grinds the outer spherical surface, the error should be controlled within 0.003-0.004mm. The grinding wheel frame should be rotated at a certain angle, and the trimming of the inner hole size of the grinding wheel should be completed before the mechanical adjustment. After the grinding wheel is blunt in the grinding process, it is not necessary to trim the inner hole, as long as the end surface of the grinding wheel is trimmed with a sandbar. The grinding zone is hot due to the intense friction. This can cause stress and deformation of the workpiece and even burn the surface of the workpiece. Therefore, a large amount of coolant must be injected during grinding to reduce the grinding temperature. The coolant can also act as chipping and lubrication. After high quality 9'' grinding wheel of the grinding wheel is blunt, the grinding force also increases, causing the abrasive grain to break or fall off, and the sharp edge is re-exposed. This characteristic is called self-sharpness. Self-sharpening allows the grinding to proceed normally within a certain period of time, but manual grinding should be performed after a certain working time to avoid vibration, noise and surface quality of the workpiece.
