摘要： PROBLEM TO BE SOLVED: To simplify a manufacturing process by substantially reducing friction between sliding members that slide with each other through lubricant.
SOLUTION: It has a face 1 that a minute recess 2 is distributed and the face slides with a mating material each other through the lubricant which is the sliding member composed of hardening steel or cast iron with a surface hardness of HRC25 to 65 and the size of an opening of the minute recess distributed on the sliding surface is in a range of 15 to 150μm and a part other than the minute recess is flat and smooth. When manufacturing the sliding member, the minute recess is formed by projecting a particle 32 of a size ranging from 0.1 mm to 0.5 mm with projection pressure in a range of 0.1 to 0.5 MPa on the surface.

摘要： PROBLEM TO BE SOLVED: To provide a device and a method for working a minute recess by which a minute recess of high accuracy is efficiently formed, and further by which the reduction of manufacturing cost is achieved.
SOLUTION: The device has a composition provided with: an arm 2 which rotatably holds a forming roller 1; a housing 3 which holds the arm 2 together with the forming roller 1 in a way that they are movable forward or backward relative to a surface F to be worked; a load applying means 4 which applies a load to the forming roller 1 brought into contact with the surface F to be worked; a load measuring means 5 which measures the load applied by the load applying means 4; and a displacement measuring means 6 which measures, in working, the distance between the arm 2 and the surface F to be worked. By the composition, a minute recess A is highly accurately and efficiently formed by controlling the pressing load of the forming roller 1 to the surface F to be worked, and a difference in the surface hardness of the surface F to be worked is determined based on the measured value of the displacement measuring means 6.

摘要： PROBLEM TO BE SOLVED: To form a minute recess with a constant depth even in the case that the contour shape of a workpiece is not detailedly obtained, by pressing a working roller against the outer peripheral face of the workpiece with a constant load, when forming a minute recess on the outer peripheral face of a workpiece.
SOLUTION: The minute recess is formed by moving a workpiece W in the Z axis direction while pressing a rolling roller 3 against an outer peripheral face Wa of the workpiece W in a state that the working roller 3 , which has minute projections and recesses 3b on its outer peripheral face 3a and is rotated on a roller shaft 2, or the workpiece W, which is rotated on a main shaft 4 parallel to the roller shaft 2, is rotated. The relative position of the working roller 3 and the workpiece W in the X axis direction is varied based on a pressing load of the working roller 3, while moving the workpiece W in the Z axis direction.
