Experimenting the influence of workpiece rotation speed and stone velocity when grinding alloy steel screws on tooth surface roughness

Abstract

Results of experimental research investigating the influence of workpiece rotation speed (v) and stone speed (n) on tooth surface roughness when grinding screws. In this article, the author researches on 38CrMo steel Acsimet screws. The screw is manufactured and ground on the 1Ƃ811 machine with the following results: Workpiece rotation speed: V = 2.1 - 7.5 rpm; Grinding wheel rotation speed: n = 12 – 25 m/s
