    • 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.

    • 要解决的问题:提供一种在机床的滑动线性运动引导件的滑动表面上以低成本构造精细凹部的方法。 解决方案:使液体射流与由石墨铸铁制成的滑动构件的表面碰撞,并且沉积在滑动构件的表面上的石墨颗粒被选择性地消除,从而在凹部的表面上形成凹部 滑动构件 当使用液体喷射碰撞的方法作为在滑动面上形成凹部的方法时,可以以低成本有效地在滑动线性运动导轨的滑动表面上形成用作油藏的凹部。 此外,用作油藏的凹部的尺寸和深度可以通过液体喷射碰撞的处理条件来调节。 此外,通过掩盖滑动面的一部分,可以容易地在作为机械滑动线性运动引导件的滑动面的可选区域中形成用作精细储油器的凹部。 版权所有(C)2011,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide a low friction sliding surface structure having a periodical structure excellent in a reciprocating sliding characteristic accompanying a stop and in a rotation sliding characteristic at a low speed. SOLUTION: A sliding surface 10a is constituted of a mirror surface part 11a such as a grid shape and the periodical structure 13a formed into each of a discrete plurality of regions 12a divided by the mirror surface part 11a. The grating shaped rugged periodical structures 13a are formed to be made uniform in parallel or orthogonally to the sliding direction X of the sliding surface 10a. The adjacent periodical structures 13a are sectioned by the mirror surface part 11a. Since both end openings of recessed parts 15 of the periodical structures 13a are dammed by the mirror surface part 11a, an oil film holding capacity of the periodical structure 13a becomes stable and is increased, and not only the reciprocating sliding characteristic but also the rotation sliding characteristic is improved.
