Details of pneumatic butterfly valve grinding
When the required surface quality requires more grinding time than the time required to remove the edge. The grinding speed shall be reduced appropriately. After testing, the following speed values are more appropriate:
① During rough grinding, the speed of the grinding tool or workpiece to be ground is 20-50m/min.
② When the pneumatic butterfly valve is finely ground, the speed of the grinding tool or workpiece is 6-12m/min.
③ Selecting the surface roughness value The surface roughness is one of the main indicators of surface quality. It has a great influence on surface function. It directly affects the surface wear, stiffness and sealing performance, and affects the performance and life of products. When different grinding methods and particle sizes are used, the surface roughness obtained is also different.
