The Ten Cores of Luoyang Aoju Bearing Science and Technology Product Quality

Luoyang Aoju Bearing Technology Co., Ltd. was established in 2010. It is a professional manufacturer of high-speed, high-precision (P2P4 level) angular contact ball bearings integrating design, research and development, and non-standard. Aoju Bearing not only has a scientific process, but its products are also widely used in aviation, aerospace, medical equipment, high-speed CNC machine tools, high-precision turntables, high-speed rolling mills, etc.

Core 1: The raw materials are all from well-known domestic steel mills,

Core 2: forging technology, scientific norms, professional technology,

Core 3: heat treatment, scientific process, standardized management, all products are subjected to -30°C-70°C cold treatment (quenching test pieces) material internal organization inspection.

Core 4: After heat treatment and quenching, put it outdoors and let it blown by wind and rain for 15 to 20 days to naturally release austenite residues, then carry out initial grinding, pickling and flaw detection

Core 5: After initial grinding, place it outdoors again for 7 to 10 days in the wind and rain to release austenite residues naturally, and then carry out fine grinding. Magnetic particle inspection

Core 6: After the fine grinding process, put it in the workshop for 3 to 5 days, then carry out the second fine grinding process, the third fine grinding process, and all the final grinding products are tested at constant temperature.

Core 7: Quality control (1): The signer of the first product inspection form, the first product inspection form is triple-type, the first responsible person for signing is the operator, the second responsible person is the inspector, the third responsible person is the Quality Inspection Department, and the fourth responsible person Everyone is in charge of production, the first inspection order can take effect, and the operator can process it. For example: without the first inspection form, the operator is not allowed to process, and if there is any violation, the responsible person will be fined 30-50 yuan each time. Company record sheet with pictures

Core 8: Quality control (2): inspection form in triplicate: the first inspection personnel quality inspection department, the second inspection personnel production supervisor, the signatory quality inspection director, the signatory operator, every day and every process If there are less than 6 inspection sheets, the responsible person will be fined 30-50 yuan each time if there is a violation.

(Core 9:) Quality control of final assembly (3): Strictly follow the assembly system, check all processes before assembly and have detailed records, check the accuracy of bearing rotation after assembly, confirm the matching load, matching method, check the amount of protrusion and do a good job Record in triplicate.

(Core 10:) Packaging requirements: the first layer of waterproof film wrapping for the bearing, the second layer of 10mm anti-collision cotton wrapping, the third layer of moisture-proof film packaging, 20mm anti-collision boards around the bottom of the wooden box, and around the wooden box after packing Wrap waterproof and moisture-proof film, stick the wooden box to indicate the model and quantity, and pack with three horizontal and three vertical straps.
