Abstract
Abstract A tubular or cylindrical metal blank is rotated and supported between a headstock and a tailstock while the lateral surface of the blank is milled by a rotary milling unit which is slidable in parallel to the axis of the blank. The axis of rotation of the milling unit is at right angles to the blank axis and may be raised or lowered relative thereto. Upon its release from the headstock and tailstock, the blank may be supported by holding means which are adjustable to bring the blank axis into parallelism with the milling unit axis, so that both ends of the blank may be milled.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
158 words
In an apparatus for machining cylindrical or tubular blanks, the combination of a machine frame, means on said frame for supporting a cylindrical or tubular blank and rotating the blank about its longitudinal axis, a milling unit slidable on said frame in parallel to the blank axis, said milling unit including a rotary mill having its axis of rotation disposed at 90* to the blank axis whereby the lateral surface of the blank may be milled by the rotary mill while the blank is rotated and the milling unit is slid on said frame, said blank supporting and rotating means comprising a headstock and a tailstock on said frame, together with additional means for supporting and translating the blank from its position between the headstock and tailstock to a position where the longitudinal axis of the blank is parallel to the axis of rotation of said mill for engagement of the ends of the blank by said mill.
Claim 2
Dependent Claim
158 words
In an apparatus for machining cylindrical or tubular blanks, the combination of a machine frame, means on said frame for supporting a cylindrical or tubular blank and rotating the blank about its longitudinal axis, a milling unit slidable on said frame in parallel to the blank axis, said milling unit including a rotary mill having its axis of rotation disposed at 90* to the blank axis whereby the lateral surface of the blank may be milled by the rotary mill while the blank is rotated and the milling unit is slid on said frame, said blank supporting and rotating means comprising a headstock and a tailstock on said frame, together with additional means for supporting and translating the blank from its position between the headstock and tailstock to a position where the longitudinal axis of the blank is parallel to the axis of rotation of said mill for engagement of the ends of the blank by said mill.
Claim 3
Dependent Claim
20 words
The apparatus as defined in claim 1 wherein said blank supporting and translating means are vertically adjustable on said frame.
Claim 4
Dependent Claim
27 words
The apparatus as defined in claim 1 wherein said blank supporting and translating means are translatable on said frame in a plane parallel to the blank axis.
Claim 5
Independent Claim
99 words
A method of machining cylindrical or tubular metal blanks, comprising the steps of (a) supporting and rotating the blank about its longitudinal axis, (b) engaging the lateral surface of the blank by a rotary mill which has its axis of rotation at right angles to the blank axis, (c) moving the rotary mill in a direction parallel to the longitudinal axis of the blank, (d) supporting and translating the blank to a position wherein its longitudinal axis is parallel to the axis of rotation of said mill, and (e) engaging the end surfaces of the blank by said mill.
Claim 6
Independent Claim
99 words
A method of machining cylindrical or tubular metal blanks, comprising the steps of (a) supporting and rotating the blank about its longitudinal axis, (b) engaging the lateral surface of the blank by a rotary mill which has its axis of rotation at right angles to the blank axis, (c) moving the rotary mill in a direction parallel to the longitudinal axis of the blank, (d) supporting and translating the blank to a position wherein its longitudinal axis is parallel to the axis of rotation of said mill, and (e) engaging the end surfaces of the blank by said mill.
Claim 7
Dependent Claim
170 words
In an apparatus for machining the lateral surface and the end surfaces of a cylindrical or tubular blank of metal, the combination of a machine frame, a milling unit slidably mounted on said frame and including a rotary mill rotatable in a plane parallel to the sliding movement of said unit, a headstock and a tailstock provided on the frame for supporting and rotating a cylindrical or tubular blank with its axis parallel to the sliding movement of said milling unit whereby the lateral surface of the blank may be machined by said mill while the latter is rotated and the milling unit is slid on the frame, and an adjustable support means provided on said frame for supporting and translating the blank from its position between the headstock and tailstock to a position where the blank axis is normal to the plane of rotation of said mill whereby the ends of the blank may be machined by the mill while the blank is held by said adjustable support means.
