J58 Direct-Drive CNC Electric Screw Press Precision Hot Forging
Press machine
Main Features,
Designed by German Schuler team, unique variable frequency and
direct-drive motor is adopted;
AC permanent magnet synchronous Motor rotor is directly connected
to flywheel, maintenance is much easier without intermediate
driving parts;
High rigidity frame, small deformation;
High sensitivity hydraulic overload protection device;
Main bolt and flywheel are connected by clearance-free pin;
High Precision energy control, good operation stability and good
consistency of products;
Super long UX" guide rail, high precision retentivity, strong load
deviation resistance;
Man-machine interface facilitates setting of parameters like blow
energy and etc.
Programmable cam controller, to ensure convenient operation and
reliable performances;
Suitable for die forging, precision punching, calibration, bending,
coining and etc;
