Product Detail


Standard / Optional



Product Introduction

Servo press machine are Servo-drive system. Built in with 9 motion curve processing modes (and can be programmed according to the processing technology of different products to achieve more motion curves), compared to ordinary press machines, it has a simple structure, high mechanical transmission efficiency, and lower maintenance costs. Forged 42CrMo alloy material crankshaft, precision-machined gears and other drive train components are designed for smooth power transmission, quiet operation and long life.

  • Next:

  • ● Heavy one-piece steel frame, minimizing deflection, high accuracy.

    ● High strength body structure, small deformation and high precision

    ● The sliding block adopts double angle hexahedral guide rail, and the sliding block guide rail adopts “high-frequency quenching” and “rail grinding process”: low wear, high precision, long precision holding time, and improves the service life of the mold.

    ● The crankshaft is made of high-strength alloy material 42CrMo. Its strength is 1.3 times that of 45 steel and its service life is longer.

    ● The copper sleeve is made of tin phosphor bronze ZQSn10-1, and its strength is 1.5 times that of ordinary BC6 brass.

    ● The use of highly sensitive hydraulic overload protection device can effectively protect the service life of the press machine and die.

    ● The standard configuration is high-precision bearing and Japanese NOK seal.

    ● 15.6 inch touch screen

    ● Optional Die Cushion.

    ● 9 processing modes are built-in, and each product can select the processing curve most suitable for component processing, so as to achieve high precision, high efficiency and high energy conservation.

    ● Compared with traditional presses, it has simple structure, high mechanical transmission efficiency and low maintenance cost.

    ● According to the characteristics of products/materials, the stamping forming speed can be reduced during the material processing to achieve the best forming speed of products/materials. Thus reducing vibration and stamping noise; Improve product accuracy and extend the service life of the mold.

    ● According to different products, different heights are required. The stroke of the punch can be set arbitrarily, which greatly shortens the stamping time and improves the efficient.
