Provided is a CNC machining device capable of more accurately measuring a shape of an object. The CNC machining deviceincludes a tool magazine, a spindle, an automatic tool replacing device, a CNC controller, a sensor headconfigured to generate measurement data corresponding to a distance from a surface of the object, and a personal computer. The sensor headgenerates measurement data (X, Z) at regular intervals. The CNC controllergenerates position coordinate data (x, y, z, xθ, yθ, zθ) at regular intervals. The sensor headtransmits the measurement data to the personal computerthrough first radio communication RC. The sensor headtransmits a synchronization signal for synchronizing the measurement data and the position coordinate data to the CNC controllerthrough second radio communication RC

A method for calibrating a CNC processing apparatus is provided that can significantly reduce the amount of operation time required for sensor calibration. A method of the present invention for calibrating a non-contact sensor in a CNC processing apparatusincludes a first step, a second step and a third step. In the first step, the center coordinates of a reference instrument are measured with a contact probe and thereby the machine coordinates of the center of the reference instrument are determined. In the second step, after a non-contact sensoris mounted onto a spindle, the center coordinates of the reference instrument are measured only one time with the non-contact sensor, and thereby the non-contact sensor coordinates of the center of the reference instrument are determined. In the third step, calculations are made to determine the amount of displacement required to bring the non-contact sensor coordinates obtained in the second step into agreement with the machine coordinates obtained with the contact probe in the first step.
