PRESSA IDRAULICA A COLONNE DA 250/80 TON PER IMBUTITURA

CRONOSSTECH CHKSP 250/80

CRONOSSTECH 250 / 80 TON FOUR-COLUMN HYDRAULIC DRAWING PRESS
General Description

The CRONOSSTECH 250 / 80-ton four-column hydraulic drawing press is a high-rigidity four-column hydraulic press solution designed for metal drawing, deep drawing, and precision pressing applications.

Its St52-grade steel frame is stress-relieved via a vibration process, ensuring superior parallelism and squareness tolerances during prolonged operation. The ram and cushion systems operate independently; stroke and pressure settings can be precisely adjusted via the touchscreen control panel.
