【 Jiaxing bearing group co. , LTD. ) Roller processing technology

There is rotational, have HRB bearing ( ） Jiaxing bearing group sales co. , LTD. Is established in spot sales center, specializing in HRB bearings, bearing applications of rich experience, today we are going to introduce roller processing technology for everyone. Roller processing: the processing technology of the steel ball should meet the standards of the finished product requirements, make steel ball has high service life, low noise, low friction and high reliability. In terms of comprehensive generally has the following several kinds of basic processing methods: 1) Pulmonary circulation processing technology for small steel ball processing and production of the few. 2) Systemic circulation processing technology used in large batch, high precision of steel ball production. 3) Single plate groove machining process used in small batch, high precision after quenching steel ball grinding and lapping. 4) Single plate groove machining process for the production of larger diameter of steel ball. 5) A single steel ball processing technology for oversize steel ball ( Ф diameter 200 mm or more) In the production. The processing technology of the steel ball as raw materials, steel ball billet specifications ( Size and precision grade) As well as the production condition varies, but the basic process is roughly same, usually has the following kinds: ( 1) Small steel ball ( Ф3 ~Ф10mm) Cold heading ball surface strengthening heat treatment processing hard grind grind lapping at the beginning of lapping 2 (1 2) Small and medium-sized steel ball ( Ф10 ~Ф16mm) Cold heading ball surface strengthening heat treatment processing hard grind grind lapping at the beginning of lapping 2 (1 3) Large steel ball ( Ф16~Ф28mm） Cold ( Hot) Heading or hot rolled annealing ( When the hot upsetting or hot rolling with) Ball surface strengthening heat treatment processing hard grind grind lapping at the beginning of lapping 2 (1 4) Large steel ball ( Ф28~Ф50mm） Heating of hot upsetting or hot rolled back light surface strengthening heat treatment processing hard at the beginning of the grinding ball grind lapping 1 lapping 2 ( 5) Oversize steel ball ( Ф50 ~Ф80mm) Material heating eager heating of hot upsetting the train back band ball hard at the beginning of the grinding heat treatment research lapping 1 lapping 2 ( 6) Oversize steel ball ( Ф80 ~Ф120mm) Material heating of hot upsetting ( Forging) The train band soft grinding ( Single grain) Hard grinding heat treatment ( Single grain) Abrasive lapping at the beginning of lapping 2 1. 24-hour customer service hotline: if you are interested in the above jiaxing bearing or have any questions, please click on contact us page on the right side of the online customer service, or call:, you close the way of jiaxing bearing purchasing advisors. - - - - - - Editor: the company jiaxing bearing sourcing consultant LTD.
