Problems solved by technology

However, in this infeed grinding, since the load on the shaft core is large, the problem of poor grinding accuracy such as deflection of the rubber roller and loss of shape accuracy such as flatness and cylindricity tends to occur during grinding.

Abstract

To shorten grinding time while exhibiting superior grinding accuracy. A rubber part 22 of a rubber roller is ground by the following grinding steps S of using a grinding wheel 10 wider than the length. The grinding steps S include a preliminary grinding step S1 for grinding by pushing the grinding wheel 10 at a first advance speed V1 of 15 to 25 mm / min toward the axis of the rubber roller 20, an intermediate grinding step S2 for grinding by pushing the grinding wheel at a second advance speed V2 lower than that speed, a finishing grinding step S3 for grinding by pushing the grinding wheel at a third advance speed V3 further lower than that speed and a sparkless grinding step S4 for holding the advance movement in a state of stopping in the final position P of the finishing grinding step S3.

Description

technical field [0001] The present invention relates to a method for manufacturing a rubber roller; more specifically, the present invention relates to a method for manufacturing a rubber roller that can be processed efficiently by grinding while maintaining a predetermined outer diameter with high precision. Background technique [0002] In copiers, facsimile machines, and printers, for transmitting paper, such as Image 6 A rubber roller c with a rubber portion b mounted around the shaft core a is shown. Moreover, when manufacturing such a rubber roller c, in general, in order to process the vulcanized rubber roller c1 with a shaft core to a predetermined outer diameter, it is necessary to grind the above-mentioned rubber portion b. [0003] However, the conventional grinding process is as Image 6 As shown, the so-called longitudinal feed grinding is used, that is, the abrasive tool e with a narrow width is in contact with the outer peripher...
