Product Description

J21 series open fixed table press

Performance characteristics

·This series of presses adopts a welded steel plate body and a rigid rotary key clutch, with a simple structure, convenient operation and maintenance, stable operation, low impact and noise;

·J21-100 and above tonnage presses all adopt a pneumatic double balance cylinder structure, with small fluctuations in balance force, balancing the weight of the slider and upper mold, and avoiding machine tool shaking caused by the above weight. It can prevent the impact and noise caused by the reverse force on the gears in the transmission, and prevent accidents caused by the sliding block falling when the brake fails or the connecting rod is broken.
