Precision Grinding Applications

  • Electro permanent magnetic design. No electric power supply required to keep the magnetic force, never generate temperatures to affect the accuracy of workpieces, suitable for precision surface grinding jobs. 

EEPG Series

Electro-Permanent Milling Magnetic Chuck

for clamping workpieces which need high accuracies. Ex : Surface grinding  

Feature

Chuck Features:

    • Electro permanent magnetic design. No electric power supply required to keep the magnetic force, never generate temperatures to affect the accuracy of workpieces, suitable for precision surface grinding jobs.
    • The power connection will be automatic cut off when the magnetism is completed, effectively reduce the power consumption and achieve the purpose of energy saving.
    • Resin-bonded structural face plate, minimizing the environmental burden.
    • The reverse demagnetization design avoids the problem of workpiece's residual magnetism. Optional air blow system is also available for easily unload the workpiece after grinding processes.
    • Strong and dense structure design, multi-layer waterproofing, excellent chuck strength and waterproof performance.
    • A variety of magnetic pole pitch can be selected, suitable for various size workpieces. Large-scale or gantry grinder, and multiple chucks can be used in combination for gantry type surface grinders.
    • A complete range of standard size chucks, and customized size chuck can also be provided to meet user needs, achieving the best cost performance.



    Controller Features:

    • Equipped with LCD display screen, can display controller information and chuck status.
    • Can be connected to the cable control box for easy operation.
    • Equipped with UL certified European standard power terminal block, can withstand 500V/32A rated voltage and current, safe and reliable.
    • Equipped with a functional terminal block, the magnetization/demagnetization function and the magnetic force adjustment can be controlled via machine's main operation panel.
    • 16-segment magnetic force adjustment, which can match different grinding operations and workpiece conditions, optimizing the magnetic force to achieve the best grinding accuracy.(The cable control box is 8-segment magnetic adjustment)

Specification

Based on customer’s requirement, multiple chucks combination and its’ control system can be customized.  Multiple chucks can simultaneously perform magnetic force adjustment, and magnetization /demagnetization operations.

Customized sizes / pole pitch is available.
