A machine tool for machining a part by on-head and continuous grinding tool profiling includes a part holder support driven into rotation by first driving means around a first axis in a vertical plane, a machining system provided with a grinding tool for machining the part, and a knurl for profiling the grinding tool. A machine by means of which the method is performed comprises a rotatingly mounted frame on which the support is fixed for winding of the layer of film. The catheter is inserted into the vasculature and heated or cooled fluid is circulated through the balloon to heat or cool blood flowing in heat-exchange proximity to the balloon, thereby effecting heating or cooling of all or a portion of the patient’s body. The transfer rack 15 delivered to the component supply section 8 is positioned by operating an automatic positioning means at the component supply section 8 in a direction in which it is loaded and unloaded and in a direction perpendicular to the direction in which it is loaded and unloaded. Each of the fixture devices comprises a column releasably mountable at a structure, an adapter releasably mountable at the column, and a head releasably mountable at the adapter. The disk drive further comprises a ramp for parking the head, and control circuitry configured to process a fly height signal generated by the TS fly height sensor, wherein the fly height signal represents a fly height of the head over the disk, and detect whether the head is on the ramp in response to the fly height signal.
