Abstract
Abstract A lathe head (work rotating device) and lathe tail stock (when required) are mounted on the table of a conventional numeric control milling machine. A tool holder and support are secured fixedly to a part of the stationary bed of the milling machine. The part to be machined is clamped in the lathe chuck and rotated by the lathe head. The mill table is programmed to move the work piece relative to the stationary tool in the required directions for machining.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
127 words
A milling table lathe comprising in combination a numerically controlled milling machine including a stationary machine bed and a numerically controlled translational milling table mounted on said bed lathe head attachment for said milling table removably mounted thereon said attachment including workpiece holding and rotating means, a fixed cutting tool holder support unit carrying a holder with a cutting tool thereon for turning a workpiece in said holding and rotating means during numeric control translation of the rotating workpiece relative to said cutting tool holder support unit while mounted on said table, said support unit including a support member for said tool holder spanning said milling table and spaced therefrom and being fixedly secured to said stationary machine bed on which said milling table is translationally mounted.
Claim 2
Dependent Claim
127 words
A milling table lathe comprising in combination a numerically controlled milling machine including a stationary machine bed and a numerically controlled translational milling table mounted on said bed lathe head attachment for said milling table removably mounted thereon said attachment including workpiece holding and rotating means, a fixed cutting tool holder support unit carrying a holder with a cutting tool thereon for turning a workpiece in said holding and rotating means during numeric control translation of the rotating workpiece relative to said cutting tool holder support unit while mounted on said table, said support unit including a support member for said tool holder spanning said milling table and spaced therefrom and being fixedly secured to said stationary machine bed on which said milling table is translationally mounted.
Claim 3
Dependent Claim
27 words
A milling table lathe as defined in claim 1, and a tail stock for the rotating workpiece in said lathe head removably mounted on said milling table.
Claim 4
Dependent Claim
85 words
A milling table lathe as defined in claim 1, said machine bed including an upright portion and a horizontal portion and said support member including a beam positioned above and across the milling table said beam including a forward end and a rear end and having its rear end secured to the upright part of said machine bed rearwardly of the milling table, the forward end of said beam being rigidly supported on a horizontal part of said machine bed forwardly of the milling table.
Claim 5
Dependent Claim
46 words
A milling table lathe as defined in claim 3, and a support post secured dependingly to the forward end of said beam, and a clamp head carried by a lower end of the post and adapted to clampingly engage said horizontal part of the machine bed.
Claim 6
Dependent Claim
33 words
A milling table lathe as defined in claim 4, and a clamp head carried by the rear end of said beam and adapted to clampingly engage the vertical part of said machine bed.
Claim 7
Dependent Claim
