Title:
BARREL FINISHING METHOD FOR INORGANIC HARD BODY
Document Type and Number:
Japanese Patent JPH01177967
Kind Code:
A
Abstract:
PURPOSE:To make it possible to inexpensively and largely manufacture an inorganic hard body having a fine lustrous surface by adding a mixture of a specific grain and an abrasive grain into liquid such as water or the like to use for the finishing of the inorganic hard body such as glass or the like. CONSTITUTION:A mixture of an abrasive grain and at least one kind selected of such grains as a walnut grain made by crushing the outer shell of the walnut, and a ceramic and a plastic grain which are porous at least on their surfaces is used as a barrel-finishing medium, and added into liquid such as water or the like, and then used for the barrel-finishing or glass, ceramics and an inorganic hard body such as a crystal. Thus the inorganic hard body having excellent weight accuracy and a lustrous surface with no struck or scratched flaw can be inexpensively and largely manufactured.
