Servo Motor Presses

ESP Series    《selling discontinued》

Features

Outstanding high-precision
- A compact direct-driven under-drive press equipped with AC servo motors and precision ball screws
- The innovative extra-high-rigidity frame with load balancing mechanism has achieved theoretically "zero" bed deflection
- The bearing guides ensure high straightness
- The high-rigidity 4-point guiding mechanism enables a high level of eccentric load resistance
- The employment of a high-precision linear scale translates into high positioning repeatability (ESP-D)

 

Improved workability and safety
- Disk brakes and rotation detecting sensors are employed for the ball screw
- A force control system is also available (optional)
- Equipped with the trial master function, which is useful for setup changes and parameter settings (optional for ESP-S, L)
High productivity
- Open sided structure facilitating automation. The machine can easily be incorporated into a mass-production line
- A guide for periodic inspections and consumables replacement is displayed
Full of useful settings
- The forming pattern selection and the multistage setting functions create optimum forming conditions
- The press motion display function allows verification of trial results (ESP-D)
Also available are highly versatile C-frame type machines
