Title:
鋳物のシール面の加工方法
Document Type and Number:
Japanese Patent JP3610716
Kind Code:
B2
Abstract:
In a method of processing a sealing surface of a casting to eliminate casting defects on or in the vicinity of the sealing surface, each of abrasive grains constituting a grindstone has a flat face formed on its distal end. The sealing surface of the casting is ground by the grindstone while the flat face of each abrasive grain is held parallel to the sealing surface of the casting. Consequently, a plastic flow layer is formed on the sealing surface of the casting. Blowholes present within a predetermined range of depth of the casting from the sealing surface are collapsed as the result of formation of the plastic flow layer.
