[0012] It is used on the machine tool and tapping machine for holes at both ends of the crankshaft. Wipe the surface of the tap with an oil-based detergent first, and then dry it with a cloth to make the surface free of dirt and oil stains, and then apply the fully synthetic oil-based anti-wear agent evenly on the surface of the tap , and then heat the tap in an oven at 50-80°C for 1 hour, dip and coat the anti-wear agent immediately after taking it out, take it out after cooling to room temperature, drip dry and use it. The wear resistance of taps treated by this process is obviously improved. The following is the use of taps after treatment with this process.

[0026] When used on a paper-shaped milling cutter, first wipe the surface with an oil-based detergent, and then dry it with a cloth to make the surface free from dirt and oil stains, then apply the fully synthetic oil-based anti-wear agent evenly on the surface of the milling cutter, and then put it in the oven to dry it. Heat at 120°C for 30 minutes, take it out and immediately immerse it in the anti-wear agent, cool it to room temperature, take it out, drip dry and use it. Each milling cutter processed by the previous process can mill 600-700 slots, but after using the process of the present invention, each milling cutter can mill 3000 slots.
example 3
[0028] The speed of various micro motors is generally more than 2000-20000 revolutions, which are used for large and small industrial equipment and household appliances. Due to cost and product requirements, a large number of motor bearings use oil-impregnated bearings. However, oil-impregnated bearings have the problems of short life and high noise. After working for about 1000 hours, due to the wear and tear of the bearing and the shaft, the gap increases, which significantly increases the noise and vibration, and some motor bearings even cause the shaft to be stuck and burn out the motor. They once tried multiple ways to improve on oily bearings, but all could not achieve better results. After the motor bearing is treated according to the above process, heat it in an oven at 130°C for 1 hour, put it in an anti-wear agent, cool it to room temperature, take it out, and use it after dripping dry. In order to enhance the effect, you can also repeat the above steps 2-3 times ,...
