An elevator guide rail machining apparatus includes a frame, a cylindrical machining tool for machining a braking surface of a guide rail, and at least one guide roller bringing an outer peripheral surface of the machining tool into parallel contact with the braking surface. When lifting or lowering the frame from a state in which the frame is suspended by a suspension member, a direction in whichthe guide roller rolls on the braking surface and which is perpendicular to the rotation axis of the guide roller is taken as the direction of rotation of the guide roller. The direction of rotationof the at least one guide roller is inclined with respect to the longitudinal direction of the guide rail.
电梯的导轨加工装置具有框架、对导轨的制动面实施加工的圆筒状加工工具以及使加工工具的外周面与制动面平行地接触的至少一个导辊。假设在从利用悬吊部件悬吊框架的状态起使框架上升或下降的情况下,导辊在制动面上滚动过去的与导辊的旋转轴垂直的方向为导辊的旋转方向。至少一个导辊的旋转方向相对于导轨的长度方向倾斜。
