CRONOSSTECH CHKSP 250/80

CRONOSSTECH 250 / 80 TON FOUR-POST HYDRAULIC FORMING PRESS
General Description

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

The St52 grade steel frame undergoes stress relief treatment by vibration method. This ensures that high parallelism and perpendicularity tolerances are maintained during prolonged operation. The ram and cushion systems operate independently; stroke and pressure settings can be precisely adjusted via the touchscreen panel.

Fitted with REXROTH or PARKER hydraulic equipment, IE3 class motor and PLC controlled system, it delivers high efficiency and reliable operation. The automatic lubrication system and electronic filter contamination warnings minimize maintenance requirements.

With its 250 / 80 ton capacity, this model is an ideal industrial press solution for mid and high-tonnage metal forming, deep drawing and die operations.

Key Advantages

- Four-post high rigidity press frame
- Independent stroke and tonnage control for ram and cushion
- Full control via touchscreen panel
- High precision and repeatability
- Long service life and low maintenance design

Application Areas

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