Introduction to Ultrasonic Cleaning Process and Advantages of Crossed Roller NSK Bearings
Appropriate selection of ultrasonic cleaning process can significantly improve cleaning efficiency and effectiveness. Choose kerosene as cleaning agent in bearing industry; choose 25kHz for ultrasonic vibration frequency; choose 7.2kW for ultrasonic cleaning power; choose 2.5min for ultrasonic cleaning time; choose room temperature for cleaning fluid; replace oil cleaning fluid once a month.
Applicability of ultrasonic cleaning
Ultrasonic waves penetrate all holes and can clean objects with complex geometric shapes and various parts with micro-holes, blind holes, narrow slits, etc. Therefore, ultrasonic cleaning is well received by the electronics, machinery, textile, optics, electroplating, magnetic materials and other industries. Such as: bearings, instruments and products with high reliability requirements.
If you choose a suitable ultrasonic cleaning process, it can also be used to clean the rust or a thin layer of oxide on the surface of the part.
Advantages of ultrasonic cleaning
From the above analysis and the effect of using crawler ultrasonic cleaning machine in our factory for more than a year, it can be seen that ultrasonic cleaning is a new way of cleaning from the cleaning principle and has unique and superior functions. The main advantages are as follows:
(1) Good quality
Using ultrasonic cleaning technology, the cleanliness of the cross roller bearing is improved, and the cleaning effect is good. As mentioned earlier, the percentage of remaining dirt after cleaning is relatively small compared to other cleaning methods. Especially for crossed roller bearing rings with teeth, ultrasonic cleaning shows its obvious superiority.
(2) High efficiency
The ultrasonic cleaning machine is suitable for mass production, and the cleaning speed is fast, which saves the cleaning time. Place the cleaned cross-roller bearing ring on the crawler in the feeding area, and move it into the cleaning tank firstly through the transmission device. The workpiece is ultrasonically cleaned through the ultrasonic cleaning area up and down; the parts after ultrasonic cleaning are automatically moved into the spray Area spraying, and then compressed air to dry the area to blow off the surface droplets of the parts. After the parts are blow-dried, they are moved to the next process, which greatly improves the production efficiency.
(3) Low labor intensity
Ultrasonic cleaning can complete the entire process from ferrule cleaning to blow-drying at one time on the production line, reducing intermediate links, reducing labor intensity, and eliminating the manual labor of cleaning workers' handling and manual wiping.
(4) Low cost
The ultrasonic cleaning machine is equipped with an automatic circulating filter device, which ensures the cleaning quality, prolongs the cleaning fluid replacement cycle, saves the cleaning agent, and has good quality and high efficiency. The cleaning staff is reduced, which obviously reduces the cost. It should be noted that although ultrasonic cleaning has started to have a large investment, the cost can be recovered soon, and the cost is still low from a long-term perspective.
(5) Guarantee production schedule
The application of ultrasonic cleaning technology for crossed cylindrical roller bearings effectively improves the passive situation of cleaning before assembly and lays a good foundation for the cleaning of finished products. It is an effective way to improve the cleanliness of finished crossed roller bearings.
