    Automation levels for traveling column grinding machines

    DIASTEP unit

    The DIASTEP unit manages all the machine functions, displays the axles, and allows you to set an automatic grinding cycle through the guided menu, thereby facilitating the operator’s task.
    Its control flexibility allows you to modify the entered parameters without interrupting the cycle. Depending on the different types of machining (continuous, pulse, plunge grinding), the cycle consists of the following stages: rough grinding, finish grinding, spark out, automatic dressing with compensation, and disengagement of the axes at the end of cycle.
    The accurate self-diagnosis allows anomalies to be controlled and displayed through alarm messages, thereby enabling unattended machining operations.

    CN PLUS Touch Screen

    CN plus ensures higher automation.
    In particular, in addition to that described for the DIASTEP unit, it allows more workpieces to be stored in the memory, as well as linear and interpolated wheel dressing on the table to use wheels with parametric profiles, multi-surface machining, and shoulder grinding on the Y-axis.

    CNC

    CNC based on SIEMENS SINUMERIK.
    The decades of experience in flat surface grinding has allowed us to create a user-friendly, yet powerful and complete operator-machine interface.
    We provide a large number of options, such as table wheel dressing with one or more diamonds or with a diamond dressing disc; integrated CAD-CAM to generate and dynamically simulate profiles whilst optimising the movement of the tool both for the grinding wheel and for the machining surface.
    The parameters related to machined workpieces and used grinding wheels can be saved in a file in the hard disk of the control unit and retrieved when needed. Moreover, an unlimited number of workpiece machining cycles can be recalled in sequence.

    Automation levels for vertical axis grinding machines

    L11

    Hundred automatic feed

    In order to improve the performance of the rotary table grinding of the LC series machines, it is possible to provide them with automatic centesimal feed of the wheelhead (L 11), an accessory allowing to carry out automatic grinding cycles.
    It includes a device which synchronizes the movements on the vertical axis of the wheelhead with the rotary motion of the work table; every two revolutions of the table, the wheelhead carries out the pre-set feed.
    The max removal in every work cycle is 1 mm which can be obtained with feeds of 0.005, 0.010 and 0.015 mm.

    L11E

    Electronic micrometric downfeed with digital readout

    Is the new electronic device for micrometric down-feed with digital readout applicable to all LC series vertical spindle grinding machines.
    A big display visualizes with micrometric resolution the position of the vertical axis that can be moved with the jog buttons or with the micrometric electronic hand-wheel. The cycle is completely automatic.
    The cycle parameters are: material to be removed, increment (min 0,001 mm), number of spark out, number of revolution of the table per increment.
    At the end of the cycle the head moves up, the grinding wheel motor, the coolant electro-pump and the table stop.
