ELECTRODEPOSITION REAMER TOOL

摘要

The electrodeposition reamer tool has a work machining portion (3) in a reamer main body composed of a finish machining portion (4) having a cylindrical outer peripheral surface and a tapered cut machining portion (5) disposed at the tip side of the finish machining portion, and abrasive grains (6) are electrodeposited on the outer peripehral surfaces of the finish machining portion and the cut machining portion. When the electrodeposition reamer tool is fitted into a blank hole in a work, the hole is expanded by the cut machining portion and the inner surface of the hole is finish-machined by the finish machining portion. Accordingly, a precision inner diameter hole having a predetermined dimension can be formed without precision pre-machining of the blank hole.
