2 new models of permanent electromagnetic chucks with magnetic force adjustable function and powerful yet good release performance! Model EPT/EPT-LW Electro Chuck master ELECTRO PERMANENT MAGNETIC CHUCK_ Most suitable for highly accurate grinding such as precision grinding •Electricity is applied momentarily only to control the magnetomotive force when mounting and dismounting workpieces, minimizing heat generated internally to ensure high precision machining operations. •Electricity needs not be applied continuously even when holding workpieces. helping reduce running costs. •The holding power is maintained by the permanent magnet in the event of power failure, improving safety. •An environment-friendly resin bonded face plate is employed. •Type EPT-LW is equipped with a low magnetic force (weak attraction) control function, which is difficult to achieve with conventiona permanent electromagnetic chucks, to facilitate stress relieving and workpiece positioning to the same level achieved by electromagnetic chucks. (When the low magnetic force control function is active, the chuck is in the continuous power-on state.) Note that this must be used together with the dedicated Chuck Master (Type EPH-LW) ^Turning the permanent electromagnetic chucks on and off must be limited to once per several minutes. If on/off soperations are repeated frequently, the chucks may be damaged by overheat.
