Grinder

Abstract

Abstract PURPOSE: To provide a less amount of distance between auxiliary table and dress point, and prevent a feed error, produced in the direction back-and-forth due to temperature changes, from being amplified in the above described point. CONSTITUTION: In accordance with the program, previously inputted to a numerical control device, with a servomotor 15, 18 driven and controlled to rotate a feed screw 6, 11, an auxiliary table 5 is moved back-and-forth together with a dressor 4, simultaneously a grindstone head 10 is up-down moved, and the periphery of a grinding wheel 9 is processed forming and dressing by the dressor 4 into a desired pattern. At this time, the distance, from a dress point 21, where the dressor 4 and the grinding wheel 9 are contacted, to the auxiliary table or the feed screw 6, being of small amount, caused an error of feed amount, casued by a temperature change and produced in back-and-forth directon of the feed screw 6, not to become amplified in this dress point. In this way, a precision of forming dimension of the grinding wheel 9 can be enhanced. COPYRIGHT: (C)1980,JPO&Japio
