The quality of anti-rust material directly affects the quality of product processing, so in the selection of anti-rust material, first according to the quality requirements for physical and chemical performance testing, qualified after the pilot test, in line with the process requirements can be used in large quantities. After entering the factory, the selected anti-rust auxiliary materials shall be strictly tested according to the quality standards of different materials. Qualified materials shall be released for use by the supply department. In the process of use of anti-rust materials and prepared solution regularly for testing, to ensure that the concentration and proportion of the solution to meet the technical requirements, to achieve the performance. The establishment of a complete material acceptance system and quality acceptance standard provides a reliable guarantee for rust prevention management.
Cooling water mainly plays the roles of cooling, lubrication, cleaning and anti-rust in bearing processing. The correct use and maintenance of cooling water directly affect the surface quality of machining parts and the service life of cutting tools. The cooling water used by the bearing can be roughly divided into soda water, emulsion liquid and synthetic grinding fluid. It is basically used to recycle more than 50 tons of tank liquid. The grinding product washed down from the grinding wheel, iron dust and oil is easy to cause the deterioration of the cooling water, resulting in the burn and rust of the processed parts. Strengthening 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 prevention process can be carried out seriously, the technical department worked out specific assessment rules according to the requirements of the process, and converted component value to the factory assessment. By the level of rust management personnel to process for discipline inspection of factory, every month to the management of the cooling water, anti-rust fluid, cleaning fluid, rust-proof oil and corrosion rate of the finished product bearing, cleanliness and oiled the packing, the rust part management level and monitoring project is a comprehensive inspection of detection of, grade assessment, and send to factory to the inspection results. From top to bottom set up a rust prevention management network, so that the rust prevention work has a good management basis.
1, when the need to clean a large number of bearings, first use the temperature of 90 ~ 100℃ hot oil to the oil to melt off, and then empty the old oil with a clean tool, and then pour hot oil to wash away the excess oil, the last step and then pour hot gasoline again.
2, clean the surface of the bearing, should choose clean gasoline, kerosene, such as the solution to clean, confirm clean after wiping with a clean rag and then coated with a thin layer of lubricating oil, and then in accordance with the standard installation process can be installed.
3, all the inspection ready to open the bearing package, the bearing should be placed in gasoline and other clean liquid and then gently by hand to turn the bearing full set, so as to the roof of the clear surface and the ball track inside the debris.
