Abstract
Abstract A turret lathe is disclosed having a first turret mounted on generally vertical slides to carry end working tools for the workpiece and having a second turret mounted on separate slides in a horizontal movement plane to carry side working tools. The envelopes of movement of the turrets do not interfere with each other permitting simultaneous cutting by tools in each of the two turrets. Numerical control is employed on both turrets for control of speed, feed and tool selection with full contouring and thread cutting capabilities. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.

Claim 2
Dependent Claim
185 words
A turret lathe, comprising in combination, a frame, a headstock journaling a spindle about a spindle axis on said frame, chuck means to grip a workpiece for rotation with said spindle, first and second tool carrying turrets journaled for indexing about first and second turret axes, respectively, first means mounting said first turret on said frame for movement in a first plane transverse to its axis and containing said spindle axis, second means mounting said second turret on said frame for movement in a second plane parallel to its axis and containing said spindle axis, said first plane being substantially perpendicular to said second plane, means for establishing said first turret axis substantially perpendicular to said second turret axis, the indexing movement of said first turret and the movement thereof in said first plane establishing a first turret movement envelope, the indexing movement of said second turret and the movement thereof in said second plane establishing a second turret movement envelope, and mEans limiting movement in said second plane of said second turret for elimination of interference with each other of said turret movement envelopes.
Claim 3
Dependent Claim
21 words
A turret lathe as set forth in claim 1, wherein said planes intersect along a line substantially at said spindle axis.
Claim 4
Dependent Claim
32 words
A turret lathe as set forth in claim 1, wherein said second mounting means establishes said second turret axis transverse to said first turret axis and substantially parallel to said second plane.
Claim 5
Dependent Claim
32 words
A turret lathe as set forth in claim 1, wherein said second mounting means establishes said second turret axis substantially perpendicular to said first axis and substantially parallel to said second plane.
Claim 6
Dependent Claim
84 words
A turret lathe as set forth in claim 1, including means holding a plurality of tools in said first tool-carrying turret with the toolholders lying in said first plane and acting on an end and internally of a workpiece in the spindle, and means holding a plurality of tools in said second tool carrying turret with the toolholders in a third plane substantially perpendicular to each of said first and second planes to work on the outer periphery of a workpiece in the spindle.
Claim 7
Dependent Claim
71 words
A turret lathe as set forth in claim 1, wherein said movement limiting means limits movement of said second turret to a minimum distance d from said spindle axis, and wherein said first turret and toolholding means therein has a thickness dimension from said spindle axis toward said second turret which thickness dimension is less than said distance d to eliminate interference with each other of said first and second turrets.
Claim 8
Dependent Claim
32 words
A turret lathe as set forth in claim 1, wherein said second turret axis is substantially parallel to said spindle axis and said first turret axis is perpendicular to said spindle axis.
Claim 9
Dependent Claim
144 words
A turret blade, comprising in combination, a frame, a headstock journaling a spindle about a spindle axis on said frame, chuck means to grip a workpiece for rotation in said spindle, first and second tool carrying turrets journaled for indexing about first and second turret axes, respectively, first means mounting said first turret on said frame for movement in a first plane transverse to its axis and containing said spindle axis, second means mounting said second turret on said frame for movement in a second plane parallel to its axis and containing said spindle axis, said first plane being substantially perpendicular to said second plane, means for establishing said first turret axis substantially perpendicular to said second turret axis, and means providing automatic control of movements in two paths in each of said first and second planes for said first and second turrets, respectively.
Claim 10
