There is, UBE's Taku Tawarada admits, a trend toward the implementation of electric machines instead of hydraulic machines. So UBE is now offering a series of electric toggle-style machines. Hydraulic machines need the pumps to be running all the time. The electric machines provide a better environment. There aren't oil leaks.
Electric machines tend to be more consistent.
Setup correctly, this means better repeatability. And done right, repeatable accuracy. The cycle time is shorter for electric machines. Hydraulic machines use oil, which means that there is time spent actuating valves and other components. With the electric machine, it is a matter of sending a signal to the motor and the equipment starts running.
