Z35 type radial drilling machine control circuit

The drilling machine can be used for drilling, enlarging, reaming, boring, scraping surfaces, attacking grooves, etc. ,. It is driven by an electric motor, and a gearbox is used to adjust
the spindle speed and feed amount. When processing threads, the forward and reverse rotation of the spindle is generally converted mechanically. Its electrical requirements are as follows.
    1) Its spindle speed adjustment range is large, so it uses multi-speed asynchronous electric motor drag, which can simplify the mechanical structure of the gearbox .
    2) The lifting, clamping and relaxing of the rocker arm should be carried out automatically; the clamping device must be automatically released before the swing arm can rise or fall. After the rocker
arm rises or falls to a designated position and stops, the clamping device can automatically clamp the rocker arm.
  3) To ensure safety, spindle rotation and rocker arm lifting are not allowed to occur at the same time.
