SPR and SPP series of Screw Presses offer different forming characteristics:
The SPR series has overload protection through a slipping clutch for forging applications which demand high working capacity.
The SPP series is capable of "hard on hard" blows for calibrating and forging applications which demand much force.
Special features of Screw Press:
Precision forging unit with accurate energy control and without fixed bottom dead centre position of ram.
High working capacity
Multi-part cast press frame pre-stressed by four tie rods
Screw made of forged high-alloy steel, with nut made of special bronze
Optimized thread profile
Frequency converter ensures accurate repeatability of the blow energy and optimum electrical efficiency
Efficient programmable control system with operator guidance, product data administration and modem for remote diagnostics
Large lateral windows in press frame facilitate automation
Capacities of Screw Press:
Nominal press force from 1.0 MN (100 t) to 80 MN (8,000 t), working capacity from 2 kJ to 2,250 kJ
