Zusammenfassung:	PURPOSE: To facilitate forming of a groove for ensuring uniform distribution of lubricating oil by forming the patterned groove as a holding portion of the lubricating oil in a surface of a workpiece with a radiation machining, in precise machining of the workpiece and its surface by honing. CONSTITUTION: When a hole 2 is precisely machined a cylindrical inner surface of a workpiece 1 having the hole 2, first a cylindrical hole wall 6 is finished in a given size, by rotating a honing tool formed by arranging a plurality of honing grinding wheels on the outer periphery and reciprocating it axially. Next, a processing device 7 that injects fluid from a nozzle 8 in a radiation tool with a high pressure is inserted into the hole 2, a groove 9 with a given pattern such as a mesh pattern is formed in a given width and depth by the fluid pressure. This groove serves as a holding portion for optimally distributing and holding lubricant. As the processing device 7, a laser device for radiating laser beams can be used.
