Long tube internal grinding equipment - consists of carriage mounted thin drive shaft rotating inside support tube

摘要

The grinding arrangement consists of a long support tube (7) in which the thin grinding drive shaft (13) is supported at a number of points in ball bearings (18). The ball bearings in turn are either supported on rings of flexible material or on balls so that the bearings can line up with any bends in the support tube. The grinding arrangement is mounted with a pivot (5) to a hydraulic cylinder (3) turn mounted on a movable trolley (1). The grinding arrangement can be raised or lowered with the hydraulic cylinder (3) and tilted about its pivot point by another hydraulic cylinder (6).
