Introduced planar masks machine miniature bearing ferrule manufacturing process steps!

As a result of the miniature bearing types much more special, so the structure of the bearing type, material selection, tolerance grade and the processing methods are different. But, the miniature bearing basic manufacturing process includes the following link: production - bearing parts Inspection - of bearing parts The demagnetization of bearing parts, cleaning and antirust processing, etc. - Bearing assembly - Check - bearing products Demagnetization and clean - bearing products Bearing the finished product oil, packaging, warehousing storage. Miniature bearing ferrule is part of the bearing is very important. And because there are many different kinds of miniature bearing, different types of miniature bearing ring size, structure, manufacturing equipment and manufacturing methods are also different. And because many ring processing procedures, sophisticated technology and high machining accuracy, so the precision of the processing quality of bearing ring, the service life and performance has very important influence. In general, the raw materials of planar masks machine miniature bearing ring is a cylindrical rod or pipe. At present, according to different molding process, the rolling bearing ring generally have the following manufacturing processes: ( 1) （ Bar) Blanking - Forging annealing ( - or fire Cold bending forming) - Heat treatment quenching and tempering Check - grinding parts Degaussing, cleaning - Assembly. ( 2) （ Bar, pipe) Blanking cold rolling forming heat treatment quenching, tempering grinding parts inspection, demagnetization, cleaning, assembly. ( 3) （ Pipe) Blanking - Turning - Forming - Heat treatment quenching and tempering Grinding - Parts check - Degaussing, cleaning - Assembly. ( 4) （ Bar) Blanking cold ( Temperature) Extrusion - Turning - Heat treatment quenching and tempering Grinding - Parts check - Degaussing, cleaning - Assembly.
