High Precision ,High Speed Press,Motor Core Lamination Press（DDH-Series）
Main performance characteristics:
® The internal oil circuit of the crankshaft is designed to restrain the thermal deformation of the crankshaft.
® The press has its own special technology to control the clearance.
® Adjustable gaskets to restore equipment accuracy with minimal cost.
® The frame pull rod and slide guide are integrated, and the structure is compact and reasonable. The slide guide is guided by ball, with high precision.
® Hydraulic locking rod, the stability can be maintained for a long time.
® The separate clutch brakes on both sides balance the force on the crankshaft and reduce bearing wear.
® The rigidity of the press frame shall be strictly controlled by 1/15000, and the frame material shall be strictly controlled by QT500-7.
