Натурні випробування крутної жорсткості станин важких токарних верстатів

Abstract

The researches of twisting stiffness of the stands of heavy lathes on the natural samples have been conducted. The objects of research are cast-iron stands of heavy lathes 1А665, 1А670, welded steel stands of deep-cutting machine КЖ1910 with thickness of vertical walls δ = 12, 16, 18 mm, welded experimental frame of machine-tools of turning type. The results of specific twisting pliability of the studied frames were obtained. The recommendations for designing and upgrading the stands of heavy lathes were given.
