Pneumatic marking machine needlealso calledMarking machine needleThe pneumatic marking machine needle is one of the most important accessories in the pneumatic marking machine. The typing quality, character line accuracy, and depth of the equipment play a decisive role. The pneumatic marking machine needle mainly uses iron and steel parts, and some are even used to print steel parts. Therefore, the hardness and toughness of the hard alloy needle core of the marking machine needle are extremely high. In addition toneedleIn addition to the extremely high requirements for the hard alloy needle core, there are also high demands for the machining accuracy of the pneumatic marking machine casing and the use of springs for the needle (as the needle operates at high frequencies). So in China, there are few manufacturers who truly master the core technology of needles; The needle tip is divided into 1.5 millimeters and 2 millimeters according to the diameter of the jademm、 threemm、 fourmm；
