Title:
METHOD OF ACCELLERATING POLISHING OF METALLIC MATERIAL IN ROTARY FINISHING DEVICE
Document Type and Number:
Japanese Patent JPH01135434
Kind Code:
A
Abstract:
PURPOSE: To shorten polishing process time by forming a polishing surface treating agent of an organic acid or its mixture or an organic acid solution having the proper concentration, and using fine metal or alloy powder having oxidation potential larger than zero. CONSTITUTION: A metal article is polished by housing and rotating a proper quantity of metal articles having average surface roughness not less than 5 μm in rotofinish equipment together with polishing lumbering chips and a polishing surface treating agent containing one kind or two or more kinds of organic acids. An organic acid solution containing an oxalic acid and/or a citric acid of 0.5 to 50%, desirably, 3 to 6% is used as this surface treating agent, and hydrogen is generated in the initial stage of polishing, and strength of a metal surface is weakened. When zirconium or zinc powder having oxidation potential of 1.5 and 0.8 V and the particle size of 0.5 to 20 μm respectively is mixed and dispersed by 0.1 to 0.8%, the hydrogen can be generated as desired, and polishing processing time can be shortened.
