I. machine tool overview
The machine can complete the boring and burnishing process of the inner hole. During machining, both the workpiece and  tool rotates and feeds at the same time. The cutting fluid enters the cutting area through the pressure head, cools and lubricates the cutting area and takes away the chips The boring method is push boring, and the cutting fluid and chips are discharged forward.
This machine tool can complete the work that the ordinary deep hole needs 2-5 working procedures. Through the combination of fine boring and burnishing, it can complete it at one time, which greatly improves the working efficiency. The machine is especially suitable for finishing all kinds of hot rolling seamless tubes.
