METHOD FOR MACHINING SLIDING MEMBER AND SLIDING LINEAR MOTION GUIDE WITH SLIDING MEMBER MANUFACTURED BY THE METHOD

摘要

PROBLEM TO BE SOLVED: To provide a method for structuring a fine recessed part at low cost on a sliding surface of a sliding linear motion guide of a machine tool.;SOLUTION: A liquid jet is made to collide with the surface of the sliding member made of graphite cast iron, and graphite particles deposited on the surface of the sliding member are selectively eliminated, thereby forming the recessed part on the surface of the sliding member. When the method of liquid jet collision is used as a method for forming the recessed part on the sliding surface, the recessed part functioning as an oil reservoir can be formed on the sliding surface of the sliding linear motion guide at low cost effectively. Moreover, the size and depth of the recessed part functioning as the oil reservoir can be adjusted by processing conditions of the liquid jet collision. Furthermore, by masking a part of the sliding surface, the recessed part functioning as the fine oil reservoir can be easily formed in an optional region on the sliding surface of the sliding linear motion guide of the machine tool.;COPYRIGHT: (C)2011,JPO&INPIT
