Gear pump grinding process

Gear pump grinding process

As a result of the existence of binder between the abrasive, the workpiece, the abrasive received the pressure is uniform, large size of the abrasive and small size of the abrasive received the pressure is more uniform, which makes the abrasive cutting depth is more uniform, resulting in shallow scratches, improve the quality of the working surface, the abrasive size uniformity requirements are lower. Abrasive is not easily embedded in the soft workpiece surface, to ensure the performance of the workpiece. 6 in the grinding process can properly control the flow of coolant, there is no coolant washed away the abrasive problem, can make the cooling effect to achieve the best, better control the workpiece temperature, to ensure the processing accuracy. In the process of grinding wear uniform, to ensure the surface accuracy of the workpiece, gear pump does not need to dressing tools, so that the processing process is simple, and reduce the requirements for the level of workers operating technology. In bulk machining, rough machining is generally adopted to copy the car or CNC car, here is not described in detail. Among the precision machining methods, at present, domestic and foreign manufacturers, mostly use the "development method" grinding plus spherical technology, its advantages lie in the high precision, good spherical, stable quality, high production efficiency. Therefore, this method is suitable for large batch production with high interchangeability requirements. For small batch production, it is relatively simple to grind the spherical surface, but the production efficiency is low and the interchangeability is poor. The following are some questions about the "developed method" for grinding the spherical surface. 4) grinding the inner sphere of the plunger cylinder body and the outer sphere of the distribution flow plate by "expansion method"
