Description

Lathe with 2 Spindle / 2 Turret minimizing installation area with 2 spindles and 2 toolbars with minimum installation area

The present invention relates to a lathe, and more particularly, to a lathe having two spindles and two toolbars, in which one of the toolbars can be moved forward, backward, left and right and up and down on a plane, When the front and rear surfaces of the workpiece are simultaneously machined, the two tool bands can be prevented from interfering with each other. Thus, since interference does not occur between the tool bands, the distance The present invention relates to a lathe having two spindles and two toolbars that minimizes the installation area that can reduce the overall installation area of the shelf.

There are a variety of machine tools for mechanically machining workpieces, and the most widely used machine tool is a lathe. The lathe can be classified into a manually operated universal lathe (manual lathe), an automatically operated numerical control lathe, and a computer numerically controlled lathe. There are many techniques related to such a shelf, for example, Patent Document 1.
