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

The frame is constructed of St52 grade steel and undergoes stress relief through vibration, ensuring high parallelism and perpendicularity tolerances during long-term operation. The ram and cushion systems operate independently; stroke and pressure settings can be precisely adjusted via the touch panel.

With hydraulic components from REXROTH or PARKER, an IE3 efficiency-class motor, and PLC-controlled system, it offers high performance and reliable operation. An automatic lubrication system and electronic filter contamination alerts minimize maintenance requirements.

With its 250 / 80 ton forming capacity, this model is an ideal industrial press solution for medium- and heavy-duty metal forming, deep drawing, and die applications.

Key Advantages

- Four-column, high-rigidity press frame
- Independent stroke and tonnage settings for the ram and cushion
- Full control via touch panel
- High precision and repeatability
- Long service life with low maintenance costs

Areas of Use

- Metal forming applications
- Deep drawing operations
- Die testing and production lines
- Auxiliary pressing processes
