Machining with fixed counterspindle

If your lathe is equipped with a second spindle, which is setup as a counterspindle and

cannot be traversed, then the workpieces must be manually reclamped

Machining with main spindle and counterspindle

For instance, a new blank can be clamped in the main spindle, and a blank that has already

been machined at the front can be clamped in the counterspindle. With the ShopTurn

program, initially the workpiece is machined in the main spindle, and then the rear side of the

workpiece, already machined at the front, is machined in the counter spindle.
