Introduction:
The JH21-125 press machine adopts the low inertia combined dry pneumatic friction clutch and brake, which has smoother press performance and easier maintenance, so to ensure reliable safety and flexible action,Iow noise, long service life.
Features:
- Steel welded body, tempering treatment or VSR(Vibratory Stress Relief), high rigidity, accuracy and stability;
- Vertical located crankshaft, compact structure;
- The crankshaft undergoes grinding treatment after high frequency quenching;
- Lengthened six-face rectangle guide with a surface of bronze plate;
- Pneumatic dual balance cylinders, which balance the slide and punch weight to reduce noise and impact;
- PLC control and imported safety duplex valve;
- Wet type combined multi discs friction clutch and brake;
- Hydraulic overload protected.
