    Finished parts

    【Main use】

    The machine is mainly used for grinding of screws with Whitworth & Acme thread and ball-screws precisely

    【NC system configuration】

    1、There are four programmable axes controlled by the SIEMENS 828D CNC system,including three synchronous ones。

    2、No. of programmable axes

    Axis Z: Table longitudinal traverse

    (With grating scale)          full close-looped

    Axis X: Wheelhead cross feed

    Axis C: Rotation of work spindle

    (With angular encoder)        full close-looped

    Axis V: Vertical feed of dresser slider

    Out of the above NC axes,C-axis and Z-axis are in a gang to make thread movement;Two electric hand-wheels can operate each NC axis by hand。

    【Working accuracy】

    1、Ball-screws:P3 (GB/T17587.3-1998) (ISO3408-3:2006), measured under dynamic state

    2、Acme screws:P6 (JB2886-92)

    【Technical characteristics】

    1、Employing a hydro-static bearing wheel spindle,the workpiece surface is greatly improved。

    2、The optimized workhead structure doubles workpiece speed,thus increasing the machining efficiency greatly。

    3、By the inteligent grinding software in man-computer interactive conversation,different wheel profiles and workpieces  profiles can be achieved conveniently。

    【Main specification parameters】
