Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a lathe, and more particularly to a lathe equipped with an auxiliary transverse table capable of processing a workpiece with high straightness.

[0002]

[Prior art]

 A lathe is a machine used to machine or cut a workpiece into a desired uniform shape. Generally, when a workpiece is machined by a lathe into a constant shape, the workpiece is fitted between a drive spindle and a tailstock of the lathe, and the drive spindle rotates the workpiece on a horizontal axis.

A rotary tool, or a tool as described above, is fixed to a transverse table placed on a cross table, and the rotary tool moves vertically to the work axis by the movement of the transversable table. By the movement of the lateral table, the workpiece is moved in parallel with the axis of the workpiece, and the workpiece is rotated normally.

US Pat. No. 5,090,278 discloses a lathe for machining a workpiece with a transversing staple on one side of the workpiece.

[0005]

[Problems to be solved by the device]

 In the above lathe, the workpiece is machined on one side by the tool, so even if cooling water is supplied to the workpiece, it depends on the frictional heat generated between the workpiece and the tool and the weight of the workpiece. Therefore, the straightness of the workpiece is easily lost. In particular, it is more difficult to maintain the straightness of a work piece such as a long lead screw used in a disc player.

Therefore, it has been difficult for a conventional lathe to machine a long work piece with high straightness at one time.

[0007]

[Means for Solving the Problems]
