Needle as a more important part of pneumatic marking machine, we all know that the role of the needle is crucial, in ensuring the quality control of the product at the same time to absorb the user's feedback information, so as to reflect the problems of the marking machine, effectively improve the shortcomings. The following to summarize the pneumatic marking machine needle which several types?
First, the domestic alloy core is used for aluminum and other soft metal materials, the biggest advantage is cheap price.
Two, the hardness of the inlet alloy core reaches HRA 93.8 degrees, which can be widely used in all kinds of metal materials with hardness lower than HRC 60 degrees. For example, the wear resistance of copper, aluminum, stainless steel and other popular alloy pins is three times.
Three, on the basis of adopting the inlet alloy, the coating and softening disposal of the coated alloy pin tip are stopped, which improves the wear resistance, greatly prolonging the application life of the pin core, and saves the specimen money over time. Even highly hardened steels such as quenched steel can be fully marked.
Four, diamond core tip is encrusted with diamond, tension hardness is higher than HRC 60 degrees, it is appropriate to mark special hardness data, such as alloy cutting tools.
