Roller processing technology

Steel ball processing technology of its products to meet the standard 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 - The ball of light - Heat treatment - Surface strengthening treatment - Hard grind - The early research - Lapping 1 - Lapping 2 ( 2) Small and medium-sized steel ball ( Ф10 ~Ф16mm) Cold heading - The ball of light - Heat treatment - Surface strengthening treatment - Hard grind - The early research - Lapping 1 - Lapping 2 ( 3) Large steel ball ( Ф16~Ф28mm） Cold ( Hot) Heading or hot - Annealing ( When the hot upsetting or hot rolling with) — The ball of light - Heat treatment - Surface strengthening treatment - Hard grind - The early research - Lapping 1 - Lapping 2 ( 4) Large steel ball ( Ф28~Ф50mm） Material heating - Hot upsetting or hot - Annealing -- The ball of light - Heat treatment - Surface strengthening treatment - Hard grind - The early research - Lapping 1 - Lapping 2 ( 5) Oversize steel ball ( Ф50 ~Ф80mm) Material heating - Eager - Heat - Hot upsetting - Annealing -- Car band - The ball of light - Heat treatment - Hard grind - The early research - — Lapping 1 - Lapping 2 ( 6) Oversize steel ball ( Ф80 ~Ф120mm) Material heating - Hot upsetting ( Forging) — Annealing -- Car band - — Soft grinding ( Single grain) — Heat treatment - Hard grinding ( Single grain) — At the beginning of grinding - Lapping 1 - Lapping 22. Roller processing roller sort is more, have a tapered roller, cylindrical roller, spherical roller, needle and screw roller, etc. Roller shape although varied, but the main processing the same. ( 1) Tapered roller processing technology (blank forming Cold heading or car) — Soft grinding diameter - Soft grinding end - Heat treatment - Finishing - Coarse grinding diameter - Fine grinding diameter - Grinding ball base - The final grinding diameter - Outside diameter crown superfinishing - Final inspection, appearance, choose don't - Oil cleaning, painting, packing, 2) Short cylindrical roller processing technology of cold upsetting forming ( Cold heading or car) — Soft grinding diameter - Soft grinding end - Heat treatment - Finishing - Coarse grinding diameter - Coarse grinding end - Fine grinding end - Fine grinding diameter - Inspection - Final grinding end - The final grinding diameter - Superfinishing diameter - Final inspection, appearance, choose don't - Clean - Oil packing ( 3) Spherical roller processing technology (blank forming Cold heading or car) — String of light - Soft grinding diameter - Soft grinding end - Heat treatment - Finishing - Coarse grinding end - Coarse grinding diameter - Final end face grinding ( Grinding ball end) — Fine grinding diameter - End mill diameter
