Technical Field

The invention relates to the field of machining equipment, in particular to a turret.

Background

The turret is an important component used in a machine tool or other machining equipment for cutting a workpiece to be machined. The prior art turrets are cutter heads with multiple stations evenly distributed around the circumference. In the machining process, when different stations need to be switched, the cutter head can be replaced by rotating the cutter disc. However, in the prior art, when machining and cutting are carried out, because a plurality of cutter heads are arranged on a cutter disc with a small area, the interference between the cutter heads is large, and the cutting machining is not facilitated. In addition, all the cutter heads rotate together during machining, so that the defects of output power loss, low rotating speed, high noise and the like are caused. And when changing the station, the turret need lift up just can change, has wasted the tool changing time, is unfavorable for the improvement of machining efficiency.
