摘要： A method of forming a moving block of a rolling motion guiding device, which prevents formation of burrs in the rolling element pathway groove and which can accurately position the moving block body in the molding die. The positioning of the moving block body in the width, height and length directions is performed by using a general surface other than the rolling element pathway groove in the moving block body. This prevents the rolling element pathway grooves from being scored. At least the both ends or the side edges of the rolling element pathway groove are gate-cut so as to prevent ingress of the molding material into the rolling element pathway groove.

摘要： A motion guide device comprises a track member (1) having a roller rolling surface (1b) thereon, a movable member (2) to be movable relatively to the track member, plural rollers (3), and a roller retainer (10). The movable member has a roller circulation passage including a loaded roller rolling surface (4d) located to be opposed to the roller rolling surface and being arranged to the track member. The rollers, each made of metal, are disposed in the roller circulation passage with a rotation axis of each roller parallel to each other to thereby circulate in response to a relative motion of the movable member to the track member. The roller retainer retains the rollers rotatably and slidably. The movable member has a contact protrusion (16) formed thereon and made of only resin, not metal. Thus, the contact protrusion comes in contact with an axis-line-direction end surface (3a) of each roller that rolls along the loaded roller rolling surface.

摘要： A method for manufacturing a slider for a linear guide device adapted to move along a track rail disposed on a fixed portion such as a bed and a column so as to guide a moving body such as a work table of a machine tool and an industrial robot under a load comprising a first process of machining a metallic block main body constituting a core of the slider into a predetermined shape and forming a surface on which a ball is caused to roll under a load on the block main body, and a second process of inserting the block main body in a mold for forming a mold forming material and forming from the mold forming material an endless circulating path for the ball, wherein the corner portion of the block main body that corresponds to a portion where the endless circulating path is formed is chamfered in the first process.

摘要： At least a ball escape hole (10) of a ball circulation passage (7) is formed of a molded body (12) and the molded body (12) is formed integrally with a block body (13) having high rigidity through an insert molding process, thereby eliminating a drilling working, possibly reducing assembling processes and reducing generation of noise.
It is preferred that the molded body (12) is provided with an inner peripheral portion of a direction changing passage (11) integrally connected with the ball escape hole (10) and joined with both end surfaces of the block body (13).
Furthermore, it is preferred that the molded body (12) is provided with a retainer (17) extending along a loaded ball passage (8) and integrally connected, at its both ends, with the inner peripheral portion of the direction changing passage (11), thereby providing a closed sectional shape surrounded by the ball escape hole portion (10), the direction changing portion (11) and the retainer portion (17).
