Product Detail


Standard / Optional



Product Introduction

QIAOSEN servo press integrates reliable engineering technology capabilities and servo drive technology, providing excellent forming technology and creating high added value for customers. Equipped with a color LCD touch screen interface, users can easily operate it at a glance.  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, allowing for easy selection of suitable processing modes and improving production efficiency. STE series servo presses are double point straight side unitized frame servo press machine,which are widely used in automotive sheet metal forming, home appliance component metal stamping, and electronic component stamping.

  • Previous:
  • Next:

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

    ● High strength body structure, small deformation and high precision.

    ● 8-points slide guiding, 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 presses and die.

    ● Forced thin re-circulating oil lubrication device, energy-saving, environmentally friendly, equipped with automatic alarm function, with better smoothness and heat dissipation, and better lubrication effect.

    ● 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.
