Metal stamping is the most widely used processing technology at present. The metal parts processed by stamping have high quality and good appearance and can be produced in large quantities at the same time. It can process all kinds of complex shapes. Then the processing oil will be used in processing. This processing oil plays a great role. It can improve the cleanliness of the metal surface, improve the processing performance, prolong its service life, and prevent the rusting performance of the processed products. So the role of this processing oil is still great, so what processing oil will be used in metal stamping processing. Now let's learn about it.

Stamping oil

Stamping oil is suitable for high-strength operations such as punching, punching, threading, slotting, etc. It is also suitable for plastic forming processing. It has good lubricity and extreme pressure and has good protection performance for the mold.

Stamping of general workpiece: the temperature rise is not much, so mineral oil can be used, but deep stamping, large workpiece stretching, thinning stretching, stainless steel stretching, etc. will have a large temperature rise, so extreme pressure antiwear agent needs to be added. In cold forging, the temperature rise is very high, and solid lubricant or dry film lubricant should be added.

Stretching oil

Drawing oil is used for metal stamping, which has excellent wear resistance and extreme pressure, will not cause workpiece galling and scratching, can improve workpiece smoothness, and effectively extend the service life of the stamping die.

Cutting oil

Cutting oil has excellent protection performance for the CNC machine tool itself, cutting tools, and workpiece. In metal cutting, cutting is carried out on the new surface every time, the speed changes from several millimeters to hundreds of meters per minute, and the pressure is as high as 2 - 3GPa. In addition to friction during cutting, there is also intramolecular friction between the tool and the cutting metal, and the interface temperature in the cutting area can reach 600 ~ 800 ℃. Such high temperature and high pressure will reduce the strength and hardness of the tool, so the cutting oil must have four functions: cooling, lubrication, cleaning, and rust prevention.

Tapping oil

Tapping oil has extremely high lubricity, which can effectively reduce the cutting temperature, to obtain maximum cutting accuracy. It is suitable for the lubrication of tapping, tapping, and other processes of stainless steel, alloy steel, ferrous metal, and non-ferrous metal products. For difficult tapping occasions, it also has efficient lubrication and cooling effect. It can also be applied to the difficult cutting of various difficult machining materials, such as high-speed turning, drilling, tapping, broaching, gear hobbing, and gear shaping of stainless steel and heat-resistant steel. After processing, these oils will remain on the metal parts to form different greasy dirt. The existence of oil will affect the quality of subsequent surface treatment processes and reduce the adhesion between the coating and the substrate.

Therefore, to improve the appearance quality, service performance, service life, and reliability of products and meet the needs of the next processing process, strict cleaning procedures must be carried out. There will also be professional cleaning agents for cleaning. Generally, we will use environmentally friendly hydrocarbon cleaning agents. This kind of cleaning agent is environmentally friendly and has a strong decontamination performance. It is a good detergent.
