According to statistics, the weight of metal products that can not be used due to corrosion is about one-third of the annual output of metal. Metal corrosion increases the maintenance and early replacement of machinery and equipment, resulting in shutdown, and the corrosion of metal products also reduces the accuracy and sensitivity, affects its use value and even scrapped.
As we all know, bearing is a precision mechanical part, which requires high precision and high surface finish. Corrosion will make the bearing lose its original precision and finish, directly affect the service performance of the bearing, reduce the service life, and even scrap.
In the process of bearing production and processing, improper anti rust management measures will cause a large number of corrosion of semi-finished products and finished parts, which will seriously affect the balance connection and the timely completion of tasks. Therefore, it is particularly important to do a good job in anti rust management. It is one of the important factors to protect product quality. It runs through the whole quality assurance system and plays a connecting role. To do a good job in rust prevention management, we must first have a scientific process management system, cultivate skilled professional managers and scientific management methods.
As a mechanical processing industry, in the processing process, the product quality must be guaranteed by a scientific and rigorous processing technology, otherwise it can not meet the quality requirements.
The bearing is composed of inner jacket, cage and rolling element. In the process of processing these four parts, different processing fluids are selected from machining to the performance of the machine tool. Select appropriate cleaning fluid, antirust fluid, antirust oil and packaging materials according to metal performance, processing process and quality requirements.
Every process involves rust prevention. In order to ensure that the product has quality in the process of processing, a complete set of scientific and rational rust prevention and advanced technology regulations is formulated. In order to ensure the effective implementation of the process and the final quality of products, the management of product processing process must be strengthened.
The front fag bearing summary to ensure product quality has a scientific, reasonable, reliable and complete anti rust management system, and adopts the secondary anti rust management system. A complete antirust process procedure and scientific antirust management system composed of machining, grinding, semi-finished product warehouse, assembly, finished product cleaning, oiling and packaging are complementary and indispensable in ensuring and improving bearing quality.
Product quality should be guaranteed not only by scientific technology, but also by high-quality managers. Rust prevention management is to “focus on prevention”, take preventive measures, and eliminate the factors causing metal corrosion in the bud, which requires skilled and high-quality managers.
Rust prevention management personnel shall first have basic theoretical knowledge of metal corrosion prevention, have a certain professional and technical level, have a full understanding of the importance of rust prevention management, have a high sense of responsibility, be able to seriously implement the rust prevention process procedures, and perform supervision and implementation.
Management method is the concrete embodiment of anti rust management. As the saying goes, there are no rules and no radius. Good scientific management method is an important means to ensure product quality. Antirust management mainly includes process management, cooling water management, antirust fluid management, cleaning fluid management, antirust oil management and antirust auxiliary NTN bearing auxiliary material management.
Each production plant of the company is a secondary anti rust management department, and the anti rust personnel are the main management personnel. They are responsible for formulating the specific anti rust operation procedures of their unit, supervising the implementation of anti rust process and detecting and monitoring anti rust water and oil during use.
