    Steel ball processing technology

    sourceվThe authortianyuanThe date of2015/1/11viewed5173

    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) the pulmonary circulation processing technology for small steel ball processing and production of the few.

    2) circulation processing technology used in large batch, high precision of steel ball production.

    3) single disc groove machining process used in small batch, high precision after quenching steel ball grinding and lapping.

    4) single disc groove plus II art used in the production of larger diameter of steel ball.

    5) a single steel ball processing technology for oversize steel ball (diameter phi 200 mm) above the production.

    The processing technology of the steel ball as raw materials, steel ball billet specifications (size and precision grade), and life

    Not the same and the difference of production conditions, but the basic process is roughly same, usually has the following kinds:

    (1) the small steel ball (phi 3 ~ $lOmm)

    Cold heading the ball in a heat treatment the surface strengthening treatment at the beginning of a hard grind, grind a lapping 1 a lapping 2

    (2) the small and medium-sized steel ball (phi 510 ~ ~ 16 mm)

    Cold heading the ball in a heat treatment the surface strengthening treatment at the beginning of a hard grind, grind a lapping 1 a lapping 2

    (3) a large ball (phi 16 ~ ~ 28 mm)

    Cold (hot) dui or hot rolled a annealing (hot upsetting or hot rolling with) a ball a heat treatment, surface strengthening processing hard grind a lapping 1 a lapping 2 at the beginning of the research

    (4) a large ball (phi 28 ~ 50 mm)

    Heating a hot upsetting or hot rolled a annealing a ball of light, heat treatment, surface strengthening treatment at the beginning of a hard grind, grind a lapping a lapping 2 l

    (5) the oversize steel ball (from 50 to 80 mm)

    Material is heated a eager a heating a hot upsetting a annealing a car band a ball at the beginning of a heat treatment, grinding hard grind a lapping 1 a lapping 2

    (6) oversize steel ball (more than 80 a phi phi 80 mm)

    Material of heating a hot upsetting (forging) a annealing a car band a soft grinding (single grain), a heat treatment at the beginning of a hard grind (single grain).
