2. Description of the Related Art A conventional film lapping machine, which is a micro finishing machine, is disclosed in, for example, Japanese Patent Publication No. 5-9225, in which a micro finishing film as a polishing tool is pressed against an outer surface or an inner surface of a workpiece. Is disclosed. In FIG. 11 of the publication, when processing a workpiece with a film, the processing is performed by applying a coolant through a nozzle to a processing point from the outside, but the processing points are multi-points or a processing zone, that is, a processed portion of the work. In the machining area where the tool is in contact with the tool, it is not possible to obtain a uniform coolant supply, so it is difficult to discharge chips between the workpiece and the tool, and the film is easily clogged, ensuring stable machining accuracy. Did not. In addition, there is a problem that chips that have not been discharged adhere to the work. JP-A-2002-103226 FIGS. 1 and 2 disclose an arrangement in which a processing area where a workpiece to be processed contacts a tool is disposed in a coolant tank.

In a conventional micro-finishing machine for processing by applying a coolant through a nozzle, a work itself or a tool itself becomes an obstacle, and ample supply of coolant to a processing point is hindered. In addition, in the case of a micro-finishing machine that processes a micro-finish film in close contact with the part to be processed, the penetration of the coolant into the processing point is prevented, so the film easily clogs and obtains a uniform and stable processed surface. And a large amount of coolant had to be supplied and a large amount of film had to be used. Further, chips adhere to the work due to the close contact of the clogged film with the work, so that the adhered material is cleaned after processing. In Japanese Patent Application Laid-Open No. 2002-103226, a processing region where a workpiece to be processed contacts a tool is arranged in a coolant tank, but clogging of a microfinishing film cannot be eliminated at all.
An object of the present invention is to minimize clogging of a microfinishing film, improve the tool life of the film, ensure a uniform and higher level of processing accuracy, and prevent chips from adhering to a workpiece after processing. It is an object of the present invention to provide a method and apparatus for processing a film wrap.

The above-mentioned problems of the prior art have been solved by a film wrap processing method and apparatus characterized by applying ultrasonic waves.
[0006]
According to the first aspect of the present invention, during processing, the coolant is applied to the machining area where the workpiece to be processed contacts the tool and the film abrasive surface of the tool by using an ultrasonic system of a coolant external type. By spraying the coolant with ultrasonic waves onto the tool during and after machining, and in the second invention of the present invention, the machining area where the workpiece to be machined contacts the tool is arranged in the coolant tank. Then, by arranging an ultrasonic generator in the coolant tank, by applying ultrasonic waves using the coolant as a medium during processing, both the adhered substances on the film abrasive grain surface in the clogged state are separated, and the coolant is removed. Cleaning efficiency, minimize clogging of micro-finish film, improve film tool life, reduce tool running costs, and increase uniform and higher Film that secures the processing accuracy of the tool and prevents the powdery chips between the contacting part of the processed part and the tool from solidifying and adhering to the processed workpiece by the physical effect of ultrasonic waves. A lap processing method and apparatus are provided.
