technical field

The utility model relates to a machining tool, in particular to a grinding machine capable of rapidly grinding drill bits and end milling cutters.

Background technique

It is very common for general tool machinery to use drills or milling cutters. Regardless of various drilling machines or electric hand tools, drills are often used for drilling and cutting. After a period of use, the drills are often dulled due to wear and tear, resulting in Drilling is not working well and the bit needs to be reground. The milling machine uses a rotating milling cutter to process a plane or contour surface. In more detail, the milling cutter performs circular cutting motion, while the processed object fixed on the machine table undergoes three-axis displacement, and In the rough milling stage, the rough milling cutter is used, and in the fine milling stage, the fine milling cutter is used. In any case, after a period of use, milling cutters will inevitably wear out to a certain extent, and how to restore the sharpness of drill bits and milling cutters is usually directly grinding the blunted drill bits and milling cutters with a grinding wheel.
