Abstract
Abstract A method and machine for machining bodies of revolution in which the part to be machined is rotated about its axis and is machined by means of a milling tool mounted on the end of a rotating spindle, whose axis is essentially perpendicular to the axis of the part to be machined, the milling tool being displaceable along a path parallel to the axis of the part, and the milling tool being adustable in height by displacement of its axis of rotation along a plane perpendicular to the axis of the part to be machined.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
139 words
A machine for machining a body of revolution comprising in combination a bed having horizontal slide means, a carriage mounted to slide on said slide means, a lathe plate, means mounting said lathe plate on said carriage spindle rotation on a vertical axis during the time of machining said body of revolution, a stationary upright mounted on said bed, said stationary upright having vertical slide means on its front face, a main carriage slidably mounted on said vertical slide means, spindle means, a milling tool carried by said spindle means, and means for mounting said spindle means on said main carriage for displacement relative to said main carriage in a plane inclined to said vertical axis, said means for mounting said spindle means on said main carriage comprising inclined slides on said carriage for slidably receiving said pindle means.
Claim 2
Dependent Claim
139 words
A machine for machining a body of revolution comprising in combination a bed having horizontal slide means, a carriage mounted to slide on said slide means, a lathe plate, means mounting said lathe plate on said carriage spindle rotation on a vertical axis during the time of machining said body of revolution, a stationary upright mounted on said bed, said stationary upright having vertical slide means on its front face, a main carriage slidably mounted on said vertical slide means, spindle means, a milling tool carried by said spindle means, and means for mounting said spindle means on said main carriage for displacement relative to said main carriage in a plane inclined to said vertical axis, said means for mounting said spindle means on said main carriage comprising inclined slides on said carriage for slidably receiving said pindle means.
Claim 3
Dependent Claim
161 words
A machine for machining a body of revolution comprising in combination a bed having horizontal slide means, a carriage mounted to slide on said slide means, a lathe plate, means mounting saId lathe plate on said carriage for rotation on a vertical axis during the time of machining said body of revolution, a stationary upright mounted on said bed, said stationary upright having vertical slide means on its front face, a main carriage slidably mounted on said vertical slide means, spindle means, a milling tool carried by said spindle means, and means for mounting said spindle means on said main carriage for radial displacement relative to said main carriage, said spindle means and said means for mounting said spindle means on said main carriage comprising a cylindrical rotating sleeve carried by said main carriage, and an eccentrically mounted spindle mounted on said cylindrical rotation sleeve co-acting therewith to effect said radial displacement, and said milling tool being mounted on said spindle.
Claim 4
Dependent Claim
