All Electric APB Series

Toyokoki company pioneered the development of the world's first 100% electric press brake. With over 30 years experience designing brakes, Toyokoki recognized the need for a new machine to meet the growing demand for shorter lot runs with greater accuracy and repeatability.

Since the repeatability of dead bottom center was dependent on oil temperature and viscosity, they developed a new machine called the APB Series which for the first time controlled the ram movement directly with heavy-duty ball screws.

Active Servo Press Brake

An AC servo motor is connected to the ball screw by a non-stretchable gear belt. The speed of the ram is dictated by the motor RPM while ram position is set by the rotary encoder on the motor. Vertical position is directly proportional to the screw rotation. The end result is the the ram positions to within +/- 0.00039 inches. That's 1 micron!
