Abstract
PURPOSE: To make it possible to evenly treat in good productivity with use of a simple device without use of liquid in such a way that spherulites of metal abrasive whose grain diameter and hardness are within the specific range are brought into a collision with ferruginous product at the specified speed.
CONSTITUTION: Spherulites or quasi-spherulites of metal abrasive which are 30W 60μ in their grain diameter and 30W800 in Vickers hardness are brought into a collision with ferruginous product at the speed of 30W50m/sec. For example, after cold forging, shell cup which is ferruginous product in Rockwell C hardness which has been done cemented quenching and tempering is put into a rotary drum type abrasive chamber and tumbled, spherulites of iron dust in Vickers hardness 440 as well as grain diameter 180μ as metal abrasive are injected at 45m/sec of injection speed, performed the treatment with abrasion, to obtain uniform excellent lustrous surface.
