How to choose precision stamping oil
(1) Silicon steel plate is a material that is relatively easy to punch. Generally, for the ease of cleaning of the finished product, low-viscosity punching oil is used on the premise of preventing punching burrs.
(2) When selecting stamping oil for carbon steel plates, the first thing you should pay attention to is the viscosity of the drawing oil. Determine the best viscosity according to the difficulty of processing, the method of drawing oil and the degreasing conditions.
(3) The galvanized steel sheet chemically reacts with chlorine-based additives, so when choosing stamping oil, attention should be paid to the problem of white rust in the chlorine-based stamping oil. The use of Yida Borun sulfur stamping oil can avoid the problem of rust. , But should be degreased as soon as possible after stamping.
(4) Stainless steel generally uses punching oil containing sulfur and chlorine compound additives to ensure extreme pressure processing performance while avoiding problems such as burrs and cracks on the workpiece.
