    Internal-External Grinding Machine KS27-60

    Traditional Internal-External Grinding Machine

    KS27-60 & KS32-100

    ( Semiautomatic with Optional Internal Grinding Unit)



    A. Straight grinding

    In small production, good grinding quality is obtained by automatic feed with spark-free timer. In mass production, the automatic external diameter measuring device (special accessories) can provide the best output and grinding effect.

    • Cross feed grinding

    Automatic intermittent feed and hydraulic driven worktable make most efficient cross-grinding of workpiece.

    • End face grinding

    Remove the rotating cover of working spindle head and replace it with a three-jaw or four-jaw chuck. Change position of the positioning tip to rotate the chuck and fix it at 90° for end grinding.

    D. Shoulder grinding

    When outer diameter of workpiece and its shoulder are to be finished once, the workpiece is supported by two centers and the grinding wheel is modified to right side of grinding wheel head, and rotated at an angle to grind.

    E. Slope grinding

    Workpiece can be supported by a chuck or two centers. Worktable and grinding wheel head can be rotated and adjusted easily.

    F. Inner diameter grinding

    Ground by Inner diameter grinding attachment (special accessory). Inner diameter grinding spindle is pulled down and fixed in grinding position, it can be ground.

    Specially designed grinding wheel spindle

    The line speed 35m/s can be adjusted to 60m/s in the case of a frequency converter. It has great efficiency improvement in grinding superhard parts such as tungsten steel and ceramics.
