GRINDER FOR GLASS PRODUCTS

摘要

PROBLEM TO BE SOLVED: To provide a glass products grinder capable of improving the grinding efficiency by restricting stay of the grinding slurry to the utmost and capable of restricting the generation of unevenness of grinding by evenly distributing the grinding slurry over the whole range of a grinding pad. SOLUTION: Three or more main grooves 7 are formed from the center of the grinding pad 6 to the peripheral edge thereof, and several grinding ranges S partitioned by these main grooves 7 are formed with several branch grooves 8 communicated with the main groove 7 at one end thereof and reaching the peripheral edge of the grinding pad 6 at the other end thereof. The main grooves 7 and the branch grooves 8 are formed into a nearly straight line, and one end of the branch groove 8 is obliquely communicated with the main groove 7 in relation to the main groove 7. The branch grooves 8 are formed in parallel with each other per each polishing range S.
