The quality of anti-rust material directly affects the quality of product processing, so when selecting anti-rust material, first test the physical and chemical properties according to the quality requirements, and then carry out the pilot test after passing the quality requirements. The selected rust-proof Auxiliary materials shall be strictly tested according to the quality standards of different materials upon entering the factory. Only after passing the test can they be issued for use by the supply department. In the use of anti-rust materials and the preparation of the solution for regular testing, to ensure that the concentration and proportion of the solution in line with the process requirements, to achieve performance. The establishment of a complete material acceptance system and quality acceptance standards provides a reliable guarantee for rust prevention management.
Cooling water plays many roles in bearing processing, such as cooling, lubrication, cleaning, rust prevention, etc. . Its correct use and maintenance directly affect the surface quality of processed parts and the service life of cutting tools. The cooling water used in the bearing can be divided into soda water, emulsion and synthetic grinding fluid, basically using more than 50 tons of tank fluid circulation, the washed grinding products, such as grinding wheel end, iron chip end and oil stain, are easy to cause the deterioration of cooling water, resulting in burn and rust of processed parts. Strengthening the scientific management of cooling water can improve its performance, ensure product quality and reduce the cost of cooling water.
In order to ensure that the rust-proof process can be carried out in earnest, the technical department according to the process requirements to formulate specific assessment rules, and conversion of component value to the production plant for assessment. Management of cooling water, antirust fluid, cleaning fluid, antirust oil, and the Rusting Rate, cleanliness and oiled packaging of finished bearings, to conduct a comprehensive check on the management level of the rust preventer and the inspection of the monitoring items, assess and score the results and send them to the production plant. From top to bottom to establish a rust management network, so that rust prevention work has a good management basis.
1. When a large number of bearings need to be cleaned, first melt the oil seal with a heat engine oil at 90-100 °c, then empty the used oil with a clean tool, then rinse it with hot oil for a while to remove the excess oil, and then, for the last step, pour hot gasoline over it.
2, clean the surface of the bearing, should choose clean gasoline, kerosene, after all the solution for cleaning, make sure to clean clean clean with a clean cloth to dry and then coated with a thin layer of lubricating oil, then follow the standard installation procedure.
3. When all checks are ready to open the bearing package, place the bearing in a clean liquid such as gasoline and gently rotate the outer sleeve of the bearing by hand so that the roof is clear and the debris in the ball track is clear.
