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.
