■ Protective fence and the safety interlock to ensure the operation safety. Have a movable single-hand pedal switch,easy to operate.
■ Front Side Covers with safety switches, Back light safety guards (Category-4) ,Foot pedal conforming to CE regulation.
2. Hydraulic System:
■A complete electrolyte servo synchro NC controlled press brake.Close loop electro-hydraulic servo-control system,the most advanced.
■Hydraulic system is from Bosch,Germany,a full loop electric-hydraulic proportional servo control By Bosch – Rexroth from Germany.
■ All seals in cylinder is PARKER from USA,Being able to work under rated load continuously,stable working and high precision.
■ The hydraulic system is made in compliance with current regulations (Directive 98/37 EC).
3. ESTUN E21NC System
■ The ESTUN E21scontrol provides a complete solution for conventional shearing machine applications.
■ In view of characteristics of shearing machine, photoelectric encoder is equipped to display position of back gauge and dead block.
■ Special functions like one side positioning display and spindle allowance offset are available to ensure unity for displayed position and actual position of back gauge.
■ Integrated with time replay, soft limit switch and power down position memorization function, E21 provides a high cost performance.
■ Main features:
● Position display of back gauge(X-axes), resolution in 0.1mm or 0.01mm
● Back gauge and Block Control
● Control for general AC motors, frequency inverter
● Intelligent positioning
● Stock Counter
● One key backup / restore of parameters
Servo proportional valve plays a synchronous role, so that the slide at both ends of the consistent decline, so the servo CNC bending machine biasing capacity is strong.
Any mold can be customized according to customer requirements. The standard mold angle is 90°, non-standard molds need to be customized, and the upper mold can be segmented.
