Fundamental Performance of a Gelatin-Based Stone for Fine Polishing

Blog Article

In this study, we have proposed a gelatin-based stone (gelatin stone) with a new polishing mechanism that can polish a free-form surface.To clarify the possibility of no face no case logo using a gelatin stone as a fine polishing tool, we experimentally examined its fundamental polishing performance.Two types of gelatin stones (jelly and gummy) were prepared.

A convex glass and a pure aluminum plate were used as work materials.The main results obtained are as follows.Polishing the convex glass with the jelly-type gelatin stone improves the surface roughness while maintaining profile masunaga tango accuracy.

The surface roughness of the pure aluminum plate can be improved by polishing with the gummy-type gelatin stone, although the polishing cannot yield a mirror-finished surface.The abrasive grains in the gelatin stones can be recovered by incineration at 600-650°C.
