Failure Analysis of jumping knife of woodworking engraving machine
Woodworking engraving machine jumping knife fault analysis: CNC woodworking engraving machine jumping knife fault is generally due to the inconsistency between the center of the engraving machine spindle rotation center and the center of the engraving machine tool during the processing process, and the rotation is not concentric. When the engraving machine spindle is running at high speed, if the engraving machine spindle and the tool are not concentric, it will not only affect the machining accuracy and machining effect, but also easily cause the cutter to break and waste. To solve the problem of jumping cutter failure of woodworking engraving machine, the first thing is to choose a cutter with high strength, sharp and smooth front cutter surface as far as possible in the machining process, and use reverse milling as far as possible in finishing. The second is to pay attention to the correctness of the upper knife. And to ensure that the Chuck, nut clean, can not have dust.
