Abstract
Abstract A turning machine with a rotary work spindle and a slide having a lower carriage movable at right angles to the spindle axis, an upper carriage movable on the lower carriage in parallelism with the axis of the spindle, and a tool support on the upper carriage. The tool support constitutes a vertically reciprocable carriage with several longitudinally extending rows for tool holders, or it may consist of at least one indexible turret with axially parallel and/or radially extending sockets for tool holders. If the tool support consists of several turrets, its turrets are either coaxial or indexible about axes which make an angel of 90 degrees with each other. Each tool turret can have two or more annuli of sockets for tool holders.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
176 words
In a machine tool, a combination comprising a frame; a work spindle rotatably mounted on said frame for carrying a workpiece to be machined; a slide including a first carriage reciprocably mounted on said frame and a second carriage reciprocably mounted on said first carriage, one of said carriages being reciprocable substantially axially and the other carriage substantially radially of said work spindle; tool support means mounted on said second carriage and comprising at least two discrete tool turrets indexibly mounted on said second carriage and each provided with at least one group of receiving means for tool holders; a prime mover; a first power train receiving motion from said prime mover and arranged to index one of said turrets; and a second power train receiving motion from said prime mover and arranged to index the other of said turrets, each of said power trains comprising discrete clutch means operable to respectively connect and disconnect the respective turret from said prime mover so that each of said turrets is indexible with or independently of the other.
Claim 2
Dependent Claim
176 words
In a machine tool, a combination comprising a frame; a work spindle rotatably mounted on said frame for carrying a workpiece to be machined; a slide including a first carriage reciprocably mounted on said frame and a second carriage reciprocably mounted on said first carriage, one of said carriages being reciprocable substantially axially and the other carriage substantially radially of said work spindle; tool support means mounted on said second carriage and comprising at least two discrete tool turrets indexibly mounted on said second carriage and each provided with at least one group of receiving means for tool holders; a prime mover; a first power train receiving motion from said prime mover and arranged to index one of said turrets; and a second power train receiving motion from said prime mover and arranged to index the other of said turrets, each of said power trains comprising discrete clutch means operable to respectively connect and disconnect the respective turret from said prime mover so that each of said turrets is indexible with or independently of the other.
Claim 3
Dependent Claim
195 words
In a machine tool, a combination comprising a frame; a work spindle for carrying a workpiece to be machined, said work spindle being mounted on said frame rotatable about a first axis; a slide including a first carriage reciprocably mounted on said frame and a second carriage reciprocably mounted on said first carriage, one of said carriages being reciprocable substantially axiaLly of and the other carriage substantially radially of said work spindle; and tool support means mounted on said second carriage and comprising a first turret indexible with respect to said second carriage about a second axis located in a plane including said first axis, said first turret being provided with at least two groups of receiving means for tool holders, said at least two groups being disposed in parallel planes spaced in the direction of said second axis from each other, said tool support means further comprising at least a second turret indexibly mounted on said second carriage about an axis which is normal to the axis of said first turret, said second turret having at least one group of tool receiving means and said second carriage being provided with bearings for said turrets.
Claim 4
Dependent Claim
195 words
In a machine tool, a combination comprising a frame; a work spindle for carrying a workpiece to be machined, said work spindle being mounted on said frame rotatable about a first axis; a slide including a first carriage reciprocably mounted on said frame and a second carriage reciprocably mounted on said first carriage, one of said carriages being reciprocable substantially axiaLly of and the other carriage substantially radially of said work spindle; and tool support means mounted on said second carriage and comprising a first turret indexible with respect to said second carriage about a second axis located in a plane including said first axis, said first turret being provided with at least two groups of receiving means for tool holders, said at least two groups being disposed in parallel planes spaced in the direction of said second axis from each other, said tool support means further comprising at least a second turret indexibly mounted on said second carriage about an axis which is normal to the axis of said first turret, said second turret having at least one group of tool receiving means and said second carriage being provided with bearings for said turrets.
Claim 5
Dependent Claim
25 words
A combination as defined in claim 2, wherein one of said first and second turrets is a multiplex turret having several groups of receiving means.
Claim 6
Dependent Claim
171 words
In a machine tool, a combination comprising a frame, a work spindle rotatably mounted on said frame for carrying a workpiece to be machined; a slide including a first carriage reciprocably mounted on said frame and a second carriage reciprocably mounted on said first carriage, one of said carriages being reciprocable substantially axially and the other carriage substantially radially of said work spindle; and tool support means mounted on said second carriage and comprising at least two discrete tool turrets indexibly mounted on said second carriage about two axes extending substantially normal to each other and located in a plane including said first axis, each of said turrets being provided with at least one group of receiving means for tool holders, one of said turrets having a front end face and the axis about which it is indexible is parallel to the axis of said work spindle, the receiving means of said one turret including at least two axially parallel sockets provided in the front end face of said one turret.
Claim 7
Dependent Claim
171 words
In a machine tool, a combination comprising a frame, a work spindle rotatably mounted on said frame for carrying a workpiece to be machined; a slide including a first carriage reciprocably mounted on said frame and a second carriage reciprocably mounted on said first carriage, one of said carriages being reciprocable substantially axially and the other carriage substantially radially of said work spindle; and tool support means mounted on said second carriage and comprising at least two discrete tool turrets indexibly mounted on said second carriage about two axes extending substantially normal to each other and located in a plane including said first axis, each of said turrets being provided with at least one group of receiving means for tool holders, one of said turrets having a front end face and the axis about which it is indexible is parallel to the axis of said work spindle, the receiving means of said one turret including at least two axially parallel sockets provided in the front end face of said one turret.
