Abstract

The carrier body (1) is mounted on the rotating shaft (2) of the machine. A shaft (9) passes through the centre of the body to machine the valve locations (A). Two slides (16) are mounted in oblique grooves (11) in the carrier body. A hollow shaft (8) is used to move the slides. Each slide has an internal mortise (17) receiving a tenor (20) formed by a flat milled on a collar at the end of the shaft (8). A piece (14) on the ends of the slides and a second piece (21) fixed to it surround an extension (4) of the carrier body. The two parts are located using grooves (23). The upper piece (21) carries the tool (24) to machine the valve seats (B). Variations include having a cutting tool fixed on the extension (4) of the body.
