Abstract
PURPOSE:To manufacture titled cylinder with minimum material loss by providing an annular groove in a required part inside of a cylinder, and expanding the ring conforming a ring having outer diameter slightly smaller than inner diameter of the rim of the annular groove to the annular groove or reducing the outer peripheral face corresponding to the annular groove of the cylinder. CONSTITUTION:An annular groove 2 is cut at a specified position inside of a cylinder 1. Next, a ring 3 having outer diameter slightly smaller than inner diameter of the rim of the annular groove 2 and made of materil which is relatively easily plastic deformed is placed on a cylindrical supporting stand 4 and held at a position that conforms to the annular groove 2. When a tapered pusher 5 is fitted to the ring 3 and pressed downward, the ring is expanded and fitted firmly in the annular groove. Otherwise, as mentioned above, after placing the ring 3 in a position that conforms to the annular ring 2, outer side of the part that corresponds to the annular groove 2 of the cylinder 1 may be reduced to fit the ring 3 in the annular groove 2.
