Servo Controlled Fine Blanking Presses

EX-FB Series

Features

The slide motion driven by the combination of an AC servo motor and mechanical linkage
- Capable of high-speed approach & return and low-speed pressing
- Clutchless structure

EX100FB
 
EX250FB

High-precision slide guide
- Preloaded roller bearings support the accurate slide movement
- In synergy with the high-rigidity frames, these presses allow fine blanking operations with utmost accuracy

Fine pressure control
- V-ring pressure and counter pressure can be accurately controlled in a wide range
- Pressures can be set to optimum values in accordance with the shape and material of the workpiece
Shearing speed control
- Pressing at a constant speed is enabled
- In combination with the fine pressure control, this function remarkably improves sheared surface quality, as well as contributing to processing quality stability and longer die life
Falcon System
- Asai's unique motion controller has newly been developed for servo controlled fine blanking presses
- Integrated control of the press machine and peripheral equipment is possible
- Equipped with a data bank function to store set conditions, and a motion monitoring function to graphically display the press motion and cushion pressure
