Press brake achieves high repeatability |

 The Toyokoki HYB, or hybrid series press brake has been developed by combining the best aspects of a conventional hydraulic brake with Toyokoki’s AC servo brakes.
Although the HYB uses hydraulic pressure to move the ram, the oil is
delivered by an AC servo motor pump which does not rely on valve
operation for precision control nor subject to variations in oil
temperature and pressure. The HYB Series is very accurate and achieves
repeatability of 0.0002 in. Lower bed crowning on the HYB is controlled
by a unique double wedge system that is adjustable across the entire
bed. The control automatically sets the amount of crown, but when
fine-tuning is necessary, the crown will automatically be adjusted to
correct the bed to match angles. The HYB also controls ram speed and
positioning with one micron resolution scales that read ram position
1,000 times a second. In turn, feedback is sent to the ram AC servo
motors to ensure that the ram velocity is constant and no over-travel
can occur.
