SURFACE WORKING METHOD AND SURFACE WORKING DEVICE FOR METAL WORK

摘要

PROBLEM TO BE SOLVED: To provide a surface working method for a metal work capable of excellently roughening the surface of the metal work.;SOLUTION: An angle α0 of spread for discharge of the horning liquid F spread for discharge in a state widened toward the end from a horning gun 1 arranged opposite to a surface Wa of the metal work W is regulated by an orifice member 2. The horning liquid F collides with a surface Wa of the work W near the discharge center line of the surface Wa, and incident angle of almost of the abrasive grains P colliding with the surface part is relatively reduced to obtain the excellent roughened surface without projections.;COPYRIGHT: (C)2002,JPO
