Abstract
The present invention relates to a method of making a slider of a linear guide device for guiding a movable body such as a work table or an industrial robot of a machine tool under load which moves along a track rail arranged at a fixed portion such as a bed, a column or the like, the method is comprising a first step of forming a block main body made of a metal which becomes a core part of the slider in a predetermined shape and forming load rolling faces of balls on the block main body by machine, and a second step of inserting the block main body formed in the first step into a mold and executing an injection molding of a synthetic resin by which ball retaining portions are built on both sides of the load rolling faces of block main body, and according to the first step pairs of smooth faces for shielding the molten synthetic resin are formed along the both edges in the longitudinal direction of the load rolling faces formed on block main body whereas according to the second step the block main body is fixed at a predetermined position in the mold by bringing a projected support portion on the side of the mold into contact with the smooth faces for shielding the molten synthetic resin.
