[Problem] To provide a preferred facility/method for manufacturing a torque sensor shaft. [Solution] A facility for manufacturing a torque sensor shaft by forming, in a predetermined pattern, a magnetostriction part including a metal glass coating on a lateral surface of a shaft-shaped work piece. The present invention is characterized by comprising: a) rotatably attaching a shaft-shaped work piece on a conveyance pallet A; b) sequentially conveying the conveyance pallet A to work devices including a pre-heating device 20 for the shaft-shaped work piece, a thermal spraying device 40 for forming a metal glass coating on a lateral surface of the shaft-shaped work piece, a masking device 60 for providing a covering part corresponding to the abovementioned pattern on the coating, and a shot blasting device 70 oriented toward the metal glass coating including the covering part; and c) performing pre-heating, thermal spraying, masking, and shot blasting on the shaft-shaped work piece while rotating the shaft-shaped work piece on the conveyance pallet A in the work devices. |
