摘要： The present invention relates to a method of manufacture of a slider of a rectilinear guide unit for guiding a movable body such as a work table of a machine tool, an industrial robot or the like by moving along an orbital rail arranged on a stationary section such as a bed, column or the like as it bears a load thereon. This method comprises a first step in which a metallic block main body as a core of the slider is machined to a predetermined shape and to form ball load rolling contact surfaces in the block main body and a second step in which the block main body machined in the previous step is inserted into a mold so as to allow a die-molding material to be padded thereon to thereby form an endless ball circulation path wherein in the first step, chamfered sections are formed on the corners of the block main body corresponding to a portion where the above-mentioned endless ball circulation path is formed.
