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.
