摘要： PURPOSE:To extend the service life of a grinding wheel gear for honing, and improve machining precision. CONSTITUTION:The grinding wheel breadth BS of a grinding wheel gear 14 for honing is set approximately at an integer time as large as the breadth of action B0 between a machined gear 9 and the gear 14. Then, the dressing of the gear 14 and the honing of the gear 9 are alternately undertaken at every section of (a), (b) and (c) equally divided according to the integer. In other word, a certain section of the sections (a), (b) and (c) equally divided according to the integer is dressed and honed, and upon the finish of the dressing and honing process, another section is dressed and honed. This process is undertaken in order for the whole of the sections (a), (b) and (c).

摘要： PURPOSE:To carry out the superfinising of the R face of a swinging workpiece with high efficiency by means of a lapping film by providing a brake cylinder for preventing the loosening of the lapping film on the driven friction wheel of a take-up reel on the driven side to maintain the stretched condition of the film. CONSTITUTION:A brake cylinder 26 for applying a pressing force to a lapping film 25 at the time of being shifted to a driven side is provided on the driven friction wheel 8, 9 portion of each take-up reel 2, 3. Therefore, even when a swinging workpiece 30 acts a sliding force on the lapping film 25 in the same direction as the moving direction thereof, the lapping film 25 is prevented from being drawn out by the pressing action of the brake cylinder 26 maintaining a stretched condition As a result, even when the polishing face of the workpiece 30 is a circular arc face like a rocker arm, the polishing face can be polished in a condition of being always in contact with the lapping film 25. At this time, the film 25 is pressed against the surface of the workpiece 30 by means of an elastic pressing member 29.

摘要： PURPOSE:To aim at preventing any scuff from occurring, by applying ECM treatment to a bore inner surface of an aluminum cylinder after honing, to the extent of depth being equivalent to Si grain size, and performing finish honing after exposing non crack Si grains to the surface. CONSTITUTION:Honing is performed to an aluminum cylinder block 1 where an Si brain 4 of 30-50mum in grain size is dispersed over its aluminum ground 3, and this aluminum ground 3 and the Si grain 4 made up of a crack 5 are exposed to a bore inner surface 2 in a state of being dispersed. Next, ECM treatment is carried out so as to become a treated depth of 30-50mum or so equal to grain size of the Si grain 4, and the Si grain 4 having no crack is the surface. Afterward, finish honing takes place with such a soft jig as a buff or the like, the Si grain 4 with no crack is stuck and fixed to a bore inner surface 2'', then it is made into a form remaining behind in a state of being projected.

摘要： PURPOSE:To prevent the sag of grooves by simultaneously machining works stacked and retained with groove positions shifted in the circumferential direction of a machining hole in a method of honing the plurality of works each having grooves on the inner surface of the machining hole. CONSTITUTION:Works 1a, 1b and 1c are stacked and clamped with a clamp mechanism 7 at the position of relatively shifting the positions of grooves on the inner surface of a machining hole 2 in the circumferential direction thereof 2. A honing tool 12 with a plurality of grinding tools 13 at an equal space in the circumferential direction in such a manner as to be free to sink reciprocates axially to machine the inner surface of the machining hole 2.
