HIGH-RIGIDITY COMPOSITE LINE BORING BAR AND MANUFACTURING METHOD THEREOF

摘要

PURPOSE: A high-rigidity composite boring bar and manufacturing method thereof is provided to improve manufacturing accuracy by manufacturing tool steels into an adapter and a tip, and the high-rigidity composite into a body of the line boring bar. CONSTITUTION: In a line boring bar, an adapter(110) and a tip(130) are made of metallic materials. A body(120) is made of a high-rigidity composite. The high-rigidity composite covers a portion of the adapter and tip. The metallic materials and the high-rigidity composite are tightly joined together at the interface.
