CONSTITUTION: A grinder(200) includes a chuck(210) for supporting a rotor(1) which is loaded by a loading finger(140) of a loading apparatus(100), a tail stock which is coupled to the chuck(210), and a turret tool(230) which is rotated at a side of the rotor(1) so as to grind an outer surface of the rotor(1). The chuck(210) includes a collet which supports a splined hole of the rotor and is protruded by a chuck cylinder provided at a rear portion of the chuck(210), and a pusher for pushing the rotor(1).
