A turning tool for machining an internal bore

Abstract

The utility model provides a tool bit of processing inner hole, and the purpose is to solve the technical problem of many tool changing times and low processing efficiency of existing inner hole processing. The cutting head has the circumferential outer wall, and the first end is equipped with the content slot along its extension direction, and the content slot has the circumferential inner wall; The first end of cutting head is equipped with first slot group and second slot group along its extension direction on its circumferential outer wall; Each slot group is matched and is installed with the mounting block, and the mounting block one end does not exceed the first end of cutting head; Each mounting block is matched and is installed with the blade, makes the blade's blade tip protrude from the first end of cutting head; The handle is installed in the second end of cutting head, and is coaxial with cutting head and is equipped, and is driven by the driving arrangement, is used to drive the handle to drive cutting head rotation. The rotation of cutting head drives two blades to rotate simultaneously to participate in the cutting of parts, improves the processing efficiency, simultaneously, the design of cutting head content slot makes the part of inner hole processing finished still center position material can continue to use.
