Screw presses with direct electric drive SPR/SPP have applications for forming, straightening, calibrating, parts made of steel, high-alloy materials and non-ferrous metals.
Screw presses with direct drive have the rotor of the drive motor connected directly to the flywheel and screw.
Lasco SPR and SPP models embody differing characteristics:
The SPR series has overload protection by means of a slipping clutch and are suitable for forging applications which demand high working capacity.
The SPP series is intended for applications which require lower energy, but is capable of 'hard on hard' blows for operations such as calibrating.
Precision forging unit with accurate energy control and without fixed bottom dead centre position of ram.
