Adopt italian dry clutch-brake, good facility and reliable safety.
Adopt HMI which can inform the failures,making maintenance
The machine adopts steel plates welded machine body, which has reliable strength and rigidness. It adopts dry friction clutch which features smooth engagement and big transmission torque, and thus it can be used at high speed. The slider guide way is plate type, and the big end of connecting rod adopts rolling bearing, which greatly improves the precision of the whole machine and the highest punching frequency can achieve 300~400 rpm. It adopts the electrical system (PAC20 Press-Automation-Control System) specially designed for punching lathe, which is controlled by variable-speed electric motor, and it make it convenient to adjust the stroke frequency of slider, simplifies the system structure and makes the system more stable and reliable. The machine features simple and convenient operation and adjustment, reliable movement, and high precision operation, which improves the performance/price ratio and shows good technical and economic profits.
