ABSTRACT:
A typical machine tool utilizes a horizontally disposed, elongated, substantially planar worktable which is supported by a knee between the ends of the worktable. When a workpiece is placed on the worktable and the worktable is moved relative to the knee in performing of the machining operations, the outer ends of the worktable will slightly sag. The structure of this invention is for a support apparatus to slightly raise the ends of the worktable so that the planar operating surface of the worktable is accurately maintained horizontal along the entire longitudinal length of the worktable.
