250/80 TONS KOLONSKA HIDRAULIČNA PRESA ZA DUBOKO VUČENJE

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-post hydraulic press solution designed for metal forming, deep drawing, and precision pressing applications.

The St52 grade steel welded frame undergoes stress-relief treatment via vibration to maintain excellent parallelism and perpendicularity tolerances even during prolonged use. The ram and cushion systems operate independently, with stroke and pressure settings precisely adjustable via the touch panel.

Equipped with REXROTH or PARKER hydraulic components, IE3 efficiency class motor, and PLC-controlled system, it ensures highly efficient and reliable operation. The automatic lubrication system and electronic filter contamination warnings minimize maintenance requirements.

With a 250 / 80 ton capacity, this model is an ideal industrial press solution for medium and high tonnage metal forming, deep drawing, and die applications.

Key Advantages

- High rigidity four-column press frame
- Independent stroke and tonnage adjustment for ram and cushion
- Full control via touch panel
- High precision and repeatability
- Long service life with low maintenance cost

Areas of Use

- Metal forming applications
- Deep drawing operations
