The basic principle of pneumatic valve sealing surface grinding

pneumatic valve sealing surface grinding is a kind of finishing machining method, can make the parts for high dimensional accuracy, geometric accuracy and surface finish, but it can't improve the interaction between the various surfaces of the position precision.
when grinding tool and the workpiece surface fit together, the middle filling abrasives, when the tool along the joint surface, complex exercise between the two parts of the abrasive grits surface sliding or rolling, part of the abrasive is embedded or sessile in tool surface, and cut off by the workpiece surface is very thin layer of metal, the convex peak on the workpiece is first grinding, gradually achieve ideal surface requirement.
in order to make each point on the surface of uniform grinding, the workpiece on every point of the relative motion of the tool route is the same as far as possible, insist on the direction of the relative movement to change.
grinding the faster the speed, the higher the efficiency, but if too much will cause the workpiece heat effects geometric accuracy, but also be careful not to put too much pressure on surface, otherwise it will cause a fever.
due to grinding is finishing processing, cutting the amount is very small, so it can guarantee to remove traces on process, under the premise of error correction workpiece geometry, grinding allowance as small as possible.
