Heading is the first of steel ball manufacture.Material wire is headed into spherical blanks by high-speed cool heading.The ball blanks have accurate form and low lateral misalingnment.The accessory pressure control system can dominate the neading stress of every steel ball.Once the pressure changes,that is,it will affect the form of blanks,the heading machine will automatically classify the ball blank. |
The imported special flashing machines not only work with high efficiency but also produce steel balls with fine basic roundness,which is the technical foundation for the production of precision steel balls. |
Steel balls are heated,quenched,cleaned and temperedin the computer-controlled Heat-Treatment work line .The precise temperature controlled system insures the uniform hardness of the balls and the structure of the balls and the structure of the balls all up to grade II.Steel balls processed by the Heat-treatment work line . |
By using a grinding disk,the hard-grinding machines not only enhance the grinding speed,but also produce steel balls with a deviation from spherical form up to 2.5,balls are clean and have no fire wound on the surface.All of the grinding machines are equipped with automatic rtueing devices for the grinding wheel and trueing diamonds. |
Steel balls are finely grinded with a grinding disk.The fine grinding machine has the advantage of high working efficiency(three times faster than normal machines) and high accuracy(deviation from spherical form up to 0.25).The whole working processis controlled by automatic measuring systems through computer.Ball fine grinding is the development direction of steel ball manufacture in future. |
To guarantee the reliability of steel balls will be inspected by AVIKO accordingto our customers'requirement.ZHONG SHAN Q.R PRECISION STEEL BALL CO.,LTD.imported the new-developed washing machine in 2000,Which is used exclusively for AVIKO.The surface of steel balls is smooth and dry,free from water and defects after washing.Having been dried by the washing machine,the steel balls can be directly sent into AVIKO for further inspection. |
The deviation from spherical form,surface roughness,diameter variation and the surface profile of balls in grade 5 are determined by the precision of super-finish machine tools.The super-finish ball lapping machine has the ability to manufacture steel balls up to G3.Steel balls finished by machines have high precision and low vibration as well.Under the confirmation,steel balls from Q.R PRECISION STEEL BALL CO.,LTD. conform to the FAG G5 quality standard. |
Zhongshan Q.R PRECISION STEEL BALL CO.,LTD.possesses following advanced instruments:roundness measuring instrument,surface roundness measuring instrument,vibration measuring instrument and computer-controlled amalysis instrument for surface defects etc... |
