Provided in the present invention is a machine tool which easily adjusts an inclination of a main shaft to a workpiece. The machine tool to perforate a hole of the desired size on the workpiece comprises: a workpiece maintaining part supported by a body part, maintaining the workpiece; a main shaft which maintains a tool; a spindle unit which has a spindle to rotatably maintain the main shaft on the rotary shaft (r); a driving unit which maintains an inclination of the unit which can changeably be maintained by the maintaining part to the workpiece, and relatively moves the unit to the workpiece; a sensor mount extended to partially envelop a circumference of the main shaft from the housing; sensors maintained by the sensor mount, and each distance of the sensors from the object to be measured measured; and a control part which calibrates an inclination of the main shaft to the workpiece by controlling the unit based on a result of the measurement by the sensors. |
