11 ABSTRACT A gib (10) for a machine tool is insertable into a space between a machine tool carriage (42) and the positive way face (40) of a set of machine tool ways (44,96) supporting the carriage (42) for rectilinear movement. The git (10) includes a body (12) having tapered ends (48) and a planar side surface (46) abutting the positive way face (40). The gib (12) further includes a fixed wedge (16) and a floating wedge (14), each of the wedges (14,16) having a crowned surface (50) in abutting relationship with one of the tapered ends (48) of the body (12), and having planar base surfaces (20,22) abutting a planar surface (38) of the carriage (42). An adjustment screw (28) traverses the body (12) and each of the wedges (14,16), and is rotatable to vary the spacing between the planar side surface (46) of the body (12) and the planar base surfaces (20,22) of the wedges (14,16). By selective adjustment of the spacing, compensation is made for wear-induced clearance between the carriage (42) and ways (44,96). to maintain the carriage (42) in accurate alignment with the ways (44,96), as it traverses the ways.
