MACHINE TOOL FOR MACHINING OF WHEEL PAIRS Russian patent published in 1994 - IPC

FIELD: mechanical engineering. SUBSTANCE: machine tool comprises spindle heads positioned on both sides of bed and carrying faceplates for mounting a wheel pair. Slides installed on guides of both bed parts have cross-feed carriages with turret heads. Said spindle heads are also installed on the slides. Upper parts of both bed portions are connected by a crosspiece which carries cross-feed carriages with cutting tools. Machine tool comprises two power and two undercutting carriages. Power carriages are mounted on slide guides which also support the spindle head. Heavy-load cutting is carried out by power carriage, slide, and spindle head which means that the load does not pass through machine bed and crosspiece thus increasing rigidity of machine several times in the course of cutting. Two undercutting carriages used for machining internal surfaces of wheels and side surfaces of brake discs are mounted on crosspiece. EFFECT: improved design. 2 cl, 4 dwg
