Abstract

437,352. Grinding. DEUTSCHE GOLDUND SILBER-SCHEIDEANSTALT VORM. ROESSLER, 7, Weissfrauenstrasse, Frankforton-Main, Germany.-(Assignees of Krug, C. ; 4, Cretzschmarstrasse, Frankfort-on-Main, Germany) Jan. 24, 1934, Nos. 2521 and 2522.

[Class 60] A method of grinding is stated to comprise the use of grinding-members consisting of corundum or silicon carbide and a binding-medium, respectively having a specific gravity below 1À9 kg. per cdm. or 1À7 kg. per cdm., and driving the member at peripheral speeds exceeding 35 metres per second, for example, 45 to 90 metres per second. When the binding-medium is an artificial resin, the specific gravities do not exceed about 1À16 kg. per cdm. and 1À07 kg. per cdm. respectively, and when a ceramic binding- medium is employed, the specific gravities do not exceed about 1À8 kg. per cdm. and 1À15 kg. per cdm. respectively. The grinding-members may incorporate hollow glass beads.
