Abstract: PURPOSE: A system for correcting the error of a work machine spindle is provided to correct the error of a spindle by measuring the error of the spindle in real-time when the spindle is rotated. CONSTITUTION: A system for correcting the error of a work machine spindle comprises a rotation system, a transfer system, and a control unit (25). The rotation system has a displacement measurement sensor for measuring the error displacement of a spindle. The transfer system has actuators (32, 33, 34) for moving a tool holder. The control unit calculates the displacement correcting value of the tool holder according to the measured error displacement value and controls the operation of the actuators to move the tool holder.

Abstract: PURPOSE: A method for manufacturing a thermoplastic polyimide resin tube is provided to improve productivity by extruding and drawing the tube through a die standing upright. CONSTITUTION: A method for manufacturing a thermoplastic polyimide resin tube is as follows. A thermoplastic polyimide resin is heated. A tube is formed by extruding the heated thermoplastic polyimide resin through an extrusion gap(113) of dies which is formed between the outer surface of an inner die(111) and the inner surface of an outer die(112), wherein the dies stand upright to make the entry of the extrusion gap face downward. The extruded tube is cooled.
