IPC: B24B3/34
Filed: 1987-12-04
Abstract: PURPOSE:To grind a tool cutting edge with high precision, by a method wherein a control means to control relative position between the cutting edge of a cutting tool held by a holding part and a grinding tray is provided, a measuring device to measure the shape precision of the cutting edge to be polished is situated on a machine, and unevenness in polishing efficiency is suppressed. CONSTITUTION:In order to suppress deterioration of cutting edge shape precision due to difference in polishing efficiency due to anisotropy of a diamond impeding cutting edge shape precision, the cutting edge of a diamond bite 3 is forcibly pressed against a polishing tray 1a in a first process. Through rotation rocking of a hold arm 4, a relative position between a diamond and a polishing tray 1a is controlled, and through integration of a plurality of fine polishing planes, a molding work is applied on the cutting edge to form a polygonal shape similar to an arc of a circle. The shape of the cutting edge is measured by a measuring device 9 on a machine, a polishing amount of the fine polishing surface is grasped, and based on the measurement, the similar polygonal shape is corrected to a similar shape to that of an arc of a circle with high precision. Thereafter, the cutting edge is formed in the arcuate shape of a round by means of a polishing tray 1b.

Title: Method of supporting calcium phosphate ceramic particle on porous body
Inventor: YASUDA MOTOI
IPC: B01D61/00
Filed: 1994-11-16
Abstract: PURPOSE: To support calcium phosphate ceramic particles on a porous body in a short time by passing through the porous body a slurry having calcium phosphate ceramic particles dispersed in the water. CONSTITUTION: When a slurry having calcium phosphate ceramic particles dispersed in the water passes through a porous body, such ceramic particles are attached to the surface of the porous body and supported thereon. In a case where an average size of the calcium phosphate ceramic particles is at most 10μm in diameter, the amount of lead adsorbed on the particle-carrying porous body is increased. Furthermore, by supporting on the carrier the calcium phosphate ceramic particles having an average film thickness more than one time the average size in diameter, the rate of lead removal of the particle- carrying porous body is made sufficient.
