Lots of machine tool manufacturers of known firms use two speed gearboxes


Examples of our works
    Retrofitting 1563
  Feed head slide of the right support is carried out by the asynchronous motor - 11kW. The motor operates by servo drive.
  The motor is connected to two speed-gearboxes 2K120.
  Planetary two-speed gearbox works the reduction 1:5 or 1:1. Reduction changes automatically. At the reduction 1:5 - feed head slide. At the reduction 1:1- rapid slide or head slide.
  The result of retrofitting is possibility of joint movement of two axes under program CNC control.
    Remanufacturing 2656
  The mechanism of changing revolution of spindle represented the difficult mechanical device. This mechanism has completely worn out. We have considered that restoration of the mechanism is not expediently.
  Gear wheels spindle boxes have been fixed in one position. Worm and two speed gearboxes 2K120 were installed. The revolution of the asynchronous motor controls by servo drive.
  After remanufacturing the choice of revolution spindle became automatically on commands from CNC control.
  Now in spindle box only one pair gear wheels is moving. It has increased a lot error-free performance and time without repair.
