There are many methods to remove oil from the surface of titanium rods, just like when the workpiece is too large and needs to be treated with coating or oil-free equipment, a brush can be used to remove oil. When using a brush to remove oil, you can use a brush or cloth dipped in metal detergents such as lime slurry, magnesium oxide, cement, soap solution, tile ash, and plant ash, and then scrub the surface with surfactants or cleaning powder. Repeat this process several times to completely remove the oil.

The drum oil removal process for titanium rod processing involves placing simple shaped small parts, such as standard parts, along with wood chips, soap pods, and weak alkaline solutions, into the drum, sealing it with a cover, and rolling it at a speed of 60-100 r/mhi to remove oil. Ultrasonic cleaning is the use of high-frequency sound waves above 16kHz, known as ultrasonic waves (beyond the frequency perceived by the human ear), to clean and remove oil. When emitting ultrasonic waves into a liquid, a compressive force is generated at a certain moment, followed by a compressive force at the next moment, and this process repeats itself. When a pressure reducing effect is generated, a vacuum space will appear in the solution, and solution vapor (water vapor, degreaser vapor) and dissolved gases in the solution will enter and form bubbles. At the moment of bubble generation, due to the compressive force, the bubble is crushed and scattered, generating a shock wave that can cause oil stains on the surface of the workpiece to detach from the workpiece. When bubbles break, they can generate high temperatures of thousands of degrees and forces of tens of thousands of kilopascals. Ultrasonic cleaning utilizes the destructive effect of shock waves on the oil film and the intense stirring effect caused by cavitation. The sound pressure generated by the reflection of ultrasonic waves is also the reason for stirring the solution.
