Because of the type, structure bearing SKF, tolerance, technical requirements, material and the difference of quantity, the basic production process are also different. Introduce the production process.
A, common SKF bearing parts processing process:
1. SKF bearing rings: inner ring and outer ring SKF bearing processing of raw materials or blank form according to the different and different, including car before processing process can be divided into the following three, the whole process for: great material or tube material (some good material must be approved by forging and annealing, is fire)-car processing-heat treatment-- let grinding and polishing parts-final inspection incoming- -rust (stay close set of assembly).
2. SKF ball bearings, ball processing again according to the different condition of raw materials and different, including cutting or before the ball of light strikes the process, can be divided into the following three, before heat treatment process, and can be divided into the following two kinds, the whole process for: great material or wire cold blunt (some good material cold rushed to blunt band and after annealing)--amid the cut, coarse grinding, RuanMo or light, heat treatment-hard ball mill-fine grinding-let or grinding-final inspection group-rust, packaging, storage < stay close set of assembly >.
3. SKF bearing maintains a: SKF bearing keep aircraft processing process according to the design structure and the different raw materials, can be divided into the following two categories:
(1), shear and sheet metal cutting, stamping, plastic and finishing, pickling or the shot peening or string of light-final inspection, rust and packaging, storage (stay close set of assembly)
(2) SKF bearing entity keep aircraft processing process: the entity kept the aircraft processing, according to the different raw materials or blank and different, including processing can be divided into the following car before four blank type, the whole process for:
Great materials, pipe materials, forging, castings, car inner diameter and outer diameter and face, chamfering--drilling (or pull holes, boring)- -antirust pickling final inspection, packaging, storage < stay close set of assembly >.
Second, SKF bearing assembly:
SKF bearing parts such as inner ring and outer, steel ball and keep wearing, after passing test, into the assembly workshop assembly, the process is as follows:
, demagnetism, their cleaning, inside and outside roll < ditch > word size packet choose don't-$set-inspection clearance and maintains a riveting, and final inspection, demagnetism, their cleaning, rust, packaging and finished products.
