Description

Technical Field

[0001] The utility model belongs to the technical field of milling cutter grinding fixtures, and in particular relates to a hard alloy milling cutter grinding fixture. Background Art

[0002] Carbide milling cutters are milling cutters made of carbide. Carbide milling cutters are generally used in CNC machining centers and CNC engraving machines. They can also be installed on ordinary milling machines to process some relatively hard and uncomplicated heat-treated materials. When the milling cutter is produced and processed, the surface of the milling cutter needs to be ground.

[0003] In the patent number CN217255223U, the utility model is named a cemented carbide milling cutter grinding fixture, which describes that "the grinding fixture utilizes the mutual cooperation between the connecting rod, the reset spring, the first clamping plate and the second clamping plate to enhance the adaptability of the device and avoid the problem that the milling cutter grinding fixture itself does not have the adaptation function. Once the size of the cemented carbide to be clamped is larger than the range that the fixture can clamp, it will lead to the inability to position the cemented carbide, thereby reducing the grinding accuracy." However, the utility model is only for milling cutters of different sizes, but the milling cutters used in different milling machines are also different, such as cemented carbide cylindrical milling cutters, cemented carbide three-sided milling cutters and cemented carbide saw blade milling cutters. Different milling cutters require different fixtures when processing, and milling cutters of different shapes cannot be clamped. The clamping effect is not stable enough, which affects the processing effect of the milling cutter; in addition, the existing fixture cannot adjust the height, which is not convenient for processing different positions of the milling cutter.
