Abstract:
1. A method for producing an actuator having a guide-equipped frame, comprising the steps of: pressing a flat plate-shaped formable steel material made of a general steel material to thereby form a frame, wherein said formable steel material from which said frame is formed is not subjected to a heat treatment for hardening said formable steel material; performing cutting machining on said frame to form long grooves therein, which are subtantially parallel to a longitudinal axis of said frame; hardening guide rails, which are made of a specialized steel material that is capable of being subjected to a hardening treatment, and thereafter grinding outer surfaces of said guide rails; and integrally joining said guide rails into said long grooves of said frame an d thereafter forming guide grooves on said guide rails, wherein said general steel material forming said frame and said specialized steel material forming said guide rails are both metals having a Young's modulus that is equal to or greater than 170 GPa.
