Kind Code:
B2
Abstract:
An object of the present invention is to provide an apparatus and a method for drilling a work which can improve the drilling accuracy and sufficiently extend the life of the cutting tool especially in its cutting performance. According to the present invention, there is provided an apparatus for drilling a work comprising a shaft portion extending from a holder for holding a drilling tool rotating around a first axis; a reduction gear connected to the shaft portion; a cylindrical member (an outer cylinder and an inner cylinder) for rotatably containing the shaft portion at an eccentric position connected to the output shaft of the reduction gear and rotating around a second axis parallel to the first axis; and a slide containing cylinder for containing the shaft portion, the reduction gear and the cylindrical member provided with a sliding structure for axially moving the shaft portion, the reduction gear and the cylindrical member characterized in that the work is drilled by simultaneously performing a rotation around the first axis, a revolution around the second axis and an axial movement of the drilling tool with rotating the drilling tool by rotating the shaft portion and simultaneously rotating the cylindrical member connected to the output shaft of the reduction gear around the second axis at a predetermined reduction ratio by rotating the input shaft of the reduction gear.
