Abstract
Abstract Each spindle assembly of the lathe has an individual drive and is arranged in a separated housing secured to a face of a rotatable pillar whose faces are intended for accommodating groups of tool rests so that the spindle of each assembly is positioned above the corresponding group of tools. The lathe is provided with a device for loading workpieces and a device for unloading finished articles, which makes the lathe fully automatic. The lathe is particularly effective for machining mass-production articles, e.g., pistons of internal combustion engines, when high efficiency, machining precision and good finish of surfaces are ensured.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
166 words
A vertical multispindle continuous lathe comprising in combination: a machine bed having upper and lower portions; a central stationary vertical post mounted on said machine bed; a pillar having faces on its external surface and disposed concentrically with said post and rotatable around it; a drive for continuous rotation of said pillar, positioned in the lower portion of said machine bed; a plurality of spindle assemblies for accommodating workpieces, each assembly having an individual drive arranged in a separate housing secured to one of said faces of the pillar; a plurality of groups of tool rests, each group being mounted on said pillar under a corresponding spindle assembly; copying means for controlling the movement of said groups of the tool rests, mounted on said stationary vertical post in its upper portion; first means for charging workpieces and second means for discharging finished workpieces, said first and second means being arranged on said machine bed and kinematically linked with said drive for continuous rotation of the pillar.
Claim 2
Dependent Claim
