High Rigidity Frame
Operability and safety
High precision guide mechanism to absorb left-right deflection

The press know-how accumulated by Komatsu over many years and the latest ICT technology are brought together in this press resulting in high accuracy, excellent reliability and easy operation.

High Rigidity Frame

A higher level of frame rigidity, essential for improved dynamic accuracy, has been achieved. Deformation is curbed and low noise and low vibration have been achieved

Operability and safety

Easy-to-see SIT4 controller for safe, secure and smooth work is equipped, and devices for preventing unexpected machine start and human entry are due.

8.4 Inch TFT LCD Monitor Achieved High Visibility

8.4inch TFT LCD monitor is equipped to operate OBS safety, surely and smoothly.2-language display also helps your global product activity.

High precision guide mechanism to absorb left-right deflection

High precision is often required on low load presses. Haven't you ever experienced cracks on corners with square blanking though nothing problem with round? OBS precisely does it.

A plunger guide mechanism is used on the drive system for absorbing the thrust force through eccentric motion not to transmit to the die. (OBS25 - 60)　Further more, the high precision is maintained for a long time together with the six face gib.
