Grinding machine having a grinding tool for generating grinding of two workpieces

Abstract

Grinding machine having a tool spindle for receiving and rotationally driving a grinding tool about a tool axis of rotation, having a first workpiece spindle for receiving a first workpiece, and having a second workpiece spindle for receiving a second workpiece, wherein the first workpiece spindle and the second workpiece spindle are arranged on one longitudinal side of the grinding tool received on the tool spindle, and both workpiece spindles are arranged parallel to one another.

What is claimed is: 
     
         1 . An apparatus comprising:
 a grinding machine having a tool spindle adapted to receive and rotationally drive a grinding tool about a tool axis of rotation, a first workpiece spindle adapted to receive a first workpiece, and a second workpiece spindle adapted to receive a second workpiece, wherein   the first workpiece spindle and the second workpiece spindle are arranged on one longitudinal side of the grinding tool received on the tool spindle,   both workpiece spindles are arranged parallel to one another,   the tool spindle is mounted so it is displaceable along a first linear guide, which extends in parallel to a horizontal inclined axis, and   the first workpiece spindle and the second workpiece spindle are spaced apart at a same perpendicular horizontal distance from the horizontal inclined axis,   wherein the tool axis of rotation forms, together with the horizontal inclined axis in a horizontal projection, an acute angle, which is greater than 0°.   
     
     
         2 . An apparatus according to  claim 1 , further comprising a machine bed, and a first linear guide, wherein the first linear guide and the two workpiece spindles are stationarily arranged. 
     
     
         3 . An apparatus according to  claim 1 , further comprising:
 a first linear carriage, which is mounted so it is movable horizontally along the first linear guide, and   a second linear carriage, which is mounted so it is horizontally movable on the first linear carriage,   wherein the second linear carriage is movable in parallel to a first horizontal axis, which, viewed in a horizontal projection, extends inclined to the horizontal inclined axis.   
     
     
         4 . An apparatus according to  claim 3 , further comprising:
 a third linear carriage, which is mounted so it is movable on the second linear carriage,   wherein the third linear carriage is movable in parallel to a first vertical axis extending perpendicular to one or more of the first horizontal axis or the horizontal inclined axis.   
     
     
         5 . An apparatus according to  claim 3 , further comprising:
 a pivot table, which is mounted so it is pivotable about a horizontal pivot axis and which carries the tool spindle, wherein the horizontal pivot axis, projected in a horizontal plane containing the first horizontal axis, extends perpendicularly to the tool axis of rotation.   
     
     
         6 . An apparatus according to  claim 5 , wherein the pivot table carries a fourth linear carriage configured to enable a linear displacement of the tool spindle in parallel to the tool axis of rotation in a lateral plane that is perpendicular to a machine bed. 
     
     
         7 . An apparatus according to  claim 1 , further comprising a machine bed, wherein the tool spindle is mounted on the machine bed by four linear guides and pivotable about a pivot axis so that the tool spindle is movable on the machine bed,
 wherein the pivot axis extends perpendicularly to a first axis of rotation of the first workpiece spindle and perpendicularly to a second axis of rotation of the second workpiece spindle, and   the first axis of rotation and the second axis of rotation are stationarily arranged on the machine bed.   
     
     
         8 . An apparatus according to  claim 1 , further comprising a handling device configured to one or more of introducing or removing workpieces in the grinding machine. 
     
     
         9 . An apparatus according to  claim 8 , wherein the handling device is arranged equidistantly to the first and second workpiece spindles, and the handling device is configured to alternately perform the handling of a first workpiece and then the handling of a second workpiece.
