BIAXIAL CONTROL DEVICE OF AN NC MACHINING DEVICE FOR THE INNER PERIPHERY OF A LARGE SIZE HOLLOW ELEMENT

摘要

PURPOSE: A biaxial control device of an NC(Numerical Control) machining device for the inner periphery of a large size hollow element is provided to carry out biaxial automatic control using a platform which moves along the X-axis.;CONSTITUTION: A biaxial control device of an NC machining device for the inner periphery of a large size hollow element comprises a platform(300), a cutting arm(400), and a rotator(700). The platform is installed on the upper side of a bed(100) and moves with the driving of a first motor(M1) along the X-axis perpendicular to the Y-axis. The cutting arm is fitted with a cutting tip(410) on an end and an engaging groove(420) axially formed on one side of the outer periphery. The rotator has a spiral groove which engages with the engaging groove and moves the cutting arm along the Y-axis.;COPYRIGHT KIPO 2011
