M248555

[Technical Field] The present invention relates to a double-edged milling cutter grinding mechanism, which is especially used to repair worn double-edged milling cutters, especially worn double-edged flat milling cutters and double ^ spherical milling cutters. [Previous technology] Pressing and milling machines use a rotating milling cutter to process a flat or contoured surface. More specifically, the milling cutter performs a circular cutting motion, and the processed object fixed on the machine performs three The displacement of the shaft uses a rough milling cutter during the rough milling stage and a fine milling cutter during the fine milling stage. In any case, after using the milling cutter for a certain period of time, a certain degree of wear and tear will inevitably occur. At this time, based on the consideration of avoiding waste, the processing industry usually uses a universal grinding machine to sharpen the sharpening knife. The problem of precision is difficult to use in the fine milling stage, but it is sufficient for the rough milling stage. Therefore, the milling cutter operation has been a routine work of milling machine manufacturers for a long time. Using a universal grinder to repair a milling cutter can reduce the amount of milling cutter replacement and help reduce costs. However, in the current situation of rising daily wages, this approach cannot really reduce costs. Because using a universal grinder to grind a milling cutter requires a certain degree of grinding technology to control the depth of the feed and the angle of the grind. At the same time, it takes a lot of time. Therefore, the time and labor required to grind the milling cutter Corresponding costs may not be lower than the purchase of a new milling cutter. Therefore, how to provide a newly designed grinding machine to reduce the technical difficulty of the milling cutter and increase the speed of the milling cutter is obviously appropriate.
