JB23 Series Punching Machine
● The series punching machine adopt rigid rotated key clutch with simple structure, easy operation and maintenance, helical gear transmission, smooth operation and low impact.
● J23-25 open inclinable punching machine, first changed from traditional sliding bearing to ball bearing with higher Wear
● Resistance, avoid generating big gear noise due to brass faster abrasion.
● J23 series open inclinable punching machine is unique in the industry with transmission brass gear
● Redesigned machine body with higher strength, at the same time, completed with ball bearing transmission ( small noise )
● J23-80 and above tonnage punching machine is in pneumaticdual-balance cylinder structure with low balance fluctuation, balancing slider and upper die weight, and avoiding machine shaking caused by afore-mentioned weight.
● Prevent gear backward force colliding and making noise,
eliminating clearance between connecting rod and slider and reducing force component impact and abrasion.
● Avoid slider falling accidents due to brake failure or connect rod breakage.
