DEEP HOLE PROCESSING DEVICE AND DEEP HOLE PROCESSING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a deep hole processing device and a deep hole processing method in which breakage and wearing of a drilling tool can be avoided or reduced without lowering productivity.;SOLUTION: The deep hole processing device related to the present invention includes: a main shaft which a drilling tool is fitted to; a feeding direction drive mechanism which drives the main shaft in the feeding direction of the drilling tool; an X-axis adjustment mechanism and a Y-axis adjustment mechanism which move the main shaft in the X-axis direction and the Y-axis direction which are orthogonal to the feeding direction and cross each other; displacement acquiring means which acquires the displacement (δX=x1-x0, δY=y1-y0) of the drilling tool position (x1, y1) during drilling processing from the drilling tool position (x0, y0) before drilling processing; and, adjustment mechanism control means which moves the position (X, Y) of the main shaft to (X+δX, Y+δY), based on the displacement (δX, δY) acquired by the displacement acquiring means.;COPYRIGHT: (C)2015,JPO&INPIT
