Universal high performance presses are widely used in the fields of auto, home appliance, hardware and etc. - details see: https://www.machineto.com/jh21-air-clutch-press-400ton-10165217

Features:

• Welded frame with quality steel which means good rigidity.
• Square figure long guide with six friction faces makes abrasion resistant and punching precision.
• Hydraulic overload protector has sensitive response and reliable motion, which can protect the die when overloading
• Combined pneumatic clutch and brake are made of friction material, which means long service life.
• Closed gear-driven, dipped in lube, which drives stably with low noise.
• Slide with counter balancer, which will eliminate the clearance and improve the stability and precision.
• Intermittent auto lubrication makes every point get fine and safe lubrication. Thus, long service life is saved.
• PLC electric control system is safe and reliable
• Air cushion, photo guard, auto feeder ,speed die changing and variable-speed device are optional.
