The MV-250E/NC four-column hydraulic press, part of the M/NC series, is specifically designed for higher precision and capacity, especially for deep drawing applications.
It features an upper and lower table made from C45E steel, equipped with DIN-650 T-slots to ensure minimal friction during the vertical movement of the upper table. This is made possible by maintenance-free bimetal bushings and perfect parallel guidance via four ground and chrome-plated cylindrical columns.
It utilizes an optimized hydraulic system operating below 290 bar to guarantee long service life and reliable performance.

FRAME AND TABLES
- Composed of three electro-welded blocks made exclusively from S355JR steel.
- Stabilized and machined after welding to ensure perfect parallelism and precision.
- Designed and calculated with finite element software.
- The lower table includes a 50-ton hydraulic cushion with a usable area of 950 x 750 mm and three front tool holders to support tools outside the press area.
- Integrated SIEMENS KTP-400 NC system for the control of upper ram travel, speed adjustment, and cushion operation.
- Features a SIEMENS S7 PLC allowing for up to 99 memory programs.

CYLINDER AND HYDRAULIC UNIT
- Single-acting cylinder with honed sleeve, chrome-plated piston rod, and wear-resistant guides.
- The entire hydraulic unit is mounted on the upper section of the press.
- Hydraulic system includes a low-noise hydraulic pump by Denison and an air-oil cooler.
- Includes:
- Decompression system
- Pressure solenoid valves
- Pre-fill valves
- Communication valve
- Check valve
- Pressure relief valve
- Safety valve

ELECTRICAL INSTALLATION AND SAFETY
- Features a SIEMENS SIMATIC S7 1200 safety PLC and a 4" KTP-400 touchscreen on the control panel. Enables programming of semi-automatic and automatic modes, power, stroke, and dwell time. Memory capacity for 99 recipes/programs, each able to store all the above parameters.
- The control panel is equipped with a selector switch to choose between manual "setup" and automatic cycle "production" modes.
- Machine operation is managed via low voltage electric foot pedals.
- For safety, the system is equipped with level IV light curtains at the front working zone, two fixed side guards, and one accessible rear guard with magnetic separation sensor.
