Title: LINEAR RECIPROCATING DEVICE AND METHOD FOR PRODUCING SAME
Abstract:
A linear reciprocating device 10 includes: a support base 11 that is equipped with a support base body 12 and a guide rail 13 provided integrally so as to protrude from the support base body 12; and a moving block 16 that is fitted to the guide rail 13 so as to be capable of reciprocating therealong. The support base 11 and the moving block 16 each comprise a substrate made from an aluminum alloy. A first thermal-sprayed film 21 is formed on the side surface of the guide rail 13, and a second thermal-sprayed film 22 is formed on the opposing surface of the moving block 16. The thermal-sprayed films 21, 22 are both made from stainless steel. Steel balls 26 are positioned between a first rolling body guide surface 23 formed on the first thermal-sprayed film 21 and a second rolling body guide surface 24 formed on the second thermal-sprayed film 22.
