This machine tool can complete the boring, skiving, burnishing and other processing procedures of the inner hole. During processing, the workpiece is fixed, the tool rotates and feeds, the cutting fluid enters the cutting area through the pressure head, cools, lubricates the cutting area, and removes chips. When boring, the push boring method is used to discharge the cutting fluid and chips forward.
Through the combination of fine boring and burnishing, it can complete at one time the job that previously required 2-3 operations to complete , which greatly improves the work efficiency. This machine is particularly suitable for the finishing of various types of fine drawn seamless tubes.
