Abstract:
A method of manufacturing a base plate, after deburring and heat-treating a half-finished base plate, cuts off a scrap section at the ends of the scrap section from a half-finished actuator attaching area so that cutting surfaces left in a finished actuator attaching area are positioned onto the inner perimeter of the finished actuator attaching area and are oriented to at least partly face an actuator attaching position inside the finished actuator attaching area.
