Abstract

The utility model provides a lathe body with a rolling guide rail and a sliding guide rail. The lathe body with the rolling guide rail and the sliding guide rail comprises the lathe main body (1), the rolling linear rail (2), the sliding hard rail (3) and a movable worktable (4). The two types of guide rails, namely the rolling linear rail and the sliding hard rail, are respectively arranged on the lathe main body to bear the movable worktable to work. In the working process, when the movable worktable is in a light load state, the rolling linear rail independently bears the movable worktable to work. When the movable worktable is in a heavy load state, the rolling linear rail and the sliding hard rail jointly bear the movable worktable to work. By means of the characteristics that the rolling linear rail is small in rolling friction and light in dragging, the dragging load and energy consumption of a Y-shaft servo motor are relieved, the defects of heavy dragging, high energy consumption and poor displacement accuracy in the prior art are overcome, the movable worktable of a numerical control milling machine is made to move, and the purposes of reducing dragging force, lowering energy consumption and improving displacement accuracy are achieved.
