Abstract
An abrasive has a plate shape with a flat surface, in which a maximum diameter of the flat surface thereof is in the range of 0.05 mm to 10 mm, and 1.5 to 100 times as the maximum diameter as thick of the abrasive, and the blast processing method is one in which this abrasive is ejected by being inclined at an incident angle with respect to a surface of a product to be treated. The ejected plate-shaped abrasive slides along the surface of the product to be treated while having the flat surface in slidable contact with the surface of the product to be treated which is an object surface to be treated, so that the surface of the product to be treated is flattened by removing the peaks only, without increasing the depth of the valleys of the roughness curve.

An abrasive for blast processing comprising a plate-shaped carrier with a flat surface, and an abrasive grain carried on at least one side of the flat surface of the carrier wherein a maximum diameter of the flat surface thereof is in a range of 0.05 mm to 10 mm,
- the maximum diameter of the flat surface is at least three times an average interval of irregularities in a surface roughness of a processed surface of a product to be treated,
- the maximum diameter of the flat surface is 1.5 to 100 times a thickness of said abrasive, and
- wherein the abrasive is adapted to achieve a sliding orientation in which the flat surface of the abrasive makes slidable contact with the surface of the product to be treated, by ejecting the abrasive at an incident angle inclined with respect to the surface of a product to be treated.
