BORING MACHINE

摘要

PURPOSE: A boring machine is provided to efficiently process the inner diameter a tube body having large diameter into circular shape by rotating a processing part. CONSTITUTION: A boring machine comprises a pair of supporting frames(10), a swing pipe(20), a drive motor(30), a bed(40), a bed transport device(50), fabrication part(60). The swing pipe is located inside the pipe or hole. The both ends of the swing pipe are installed in the supporting frame to rotate. The drive motor is connected to the swing pipe to rotate the swing pipe. A base part of the bed is combined in guide rails of the swing pipe to slide. The bed transport device is composed of a lead screw and a drive motor. The lead screw is installed in the swing pipe in parallel with the guide rail. The drive motor is connected to the lead screw. The fabrication part is installed in the tip-end part of the bed. The fabrication part adheres closely to the inner circumference of the pipe or hole to process the inner circumference.
