PROBLEM TO BE SOLVED: To provide elliptic spinning lathe equipment which gives a worktable elliptic rotational motions of various forms and sizes as well as the rotational motion by a rotary main shaft, by arbitrarily changing the setting of dimensions of major and minor axes of an ellipse. SOLUTION: The elliptic spinning lathe equipment has the worktable 1 provided fixedly on the inner ring 6 of a bearing 5 which revolves, interlocking with crank gearings A, B, etc., while the rotary main shaft 2 is fitted to the worktable 1 through a linear slide comprising a linear rail 3 and a slider 4, and the equipment is so constituted that the ratio of rotational frequency between the crank gearings A, B, etc., and the rotary main shaft 2 is 2 to 1. In the equipment, the outer ring 7 of the bearing 5 supporting the worktable 1 is driven to revolve by at least three crank gearings A, B and C and thereby stable and smooth revolving motions of the equipment are enabled.
