Abstract
PURPOSE:To make it possible to simply and easily attain super-finishing in the order of 0.1mum R max with a roundness degree of several mum, by applying a combined action of electrolytic action and abrasive grinding action together to a cylinder which has previously been machined by an ordinary lathe. CONSTITUTION:A supplying port 4 opening into a concavity 3 of an electrode 1 is provided by forming in a tool electrode 1 the concavity which has a radius somewhat larger than the radius of an anodic cylindrical workpiece 2. Then, an electrolytic action and grinding action with the use of abrasive 5 are put together into a composite action for the purpose of super-finishing the external surface of the workpiece 2 in such a way that the concavity 3 of the electrode 1 is provided oppositely to the workpiece 2 with a clearance between the electrode 1 and the external surface of the workpiece 2, abrasive 5 is interposed between the external surface of the workpiece 2 and the arcuate end face of the electrode 1, electrolytic liquid 6 is supplied from a supplying port 4, the workpiece 2 is rotated in the direction indicated by the longer arrow, the electrode 1 is converted into a cathode, and at the same time, the workpiece 2 is rendered anodic. In other words, even if there is 10-40mum of rotational torsion, it is possible to make a subsequent finishing of a mum order of roundness and 0.05-0.1mum R max of surface smoothness.
