MT HD Testing Benches

Stationary magnetizing benches MAS HD series (heavy duty) are intended for inspection of ferromagnetic parts up to 430 mm diameter, 920 mm length and 100 kg weight.

The advantage is the possibility of using circular and longitudinal magnetization simultaneously, allowing indicate flaws in more directions in one cycle, compared to separate magnetization.
Next advantage is longitudinal magnetization using coils integrated in the tailstocks, which is less time consuming and simpler for operator, unlike the magnetization using the moving coil.

Standard delivery for all models MAS 500 / 700 / 900 HD

  • cirkulární magnetizace průchodem prouducircular magnetization by passing the current
  • longitudinal magnetization by coils integrated in     the clamping tailstocks
  • combined magnetization can be used – both circular and longitudinal simultaneously
  • automatic AC demagnetization at the and of testing
  • level monitoring of reached currents
  • the bench is equipped with stationary switchboard with sources of magnetizing current and control panel, girder for suspension UV lamp, pump, application nozzles for automatic applying and shower for manual applying of the suspension
  • these benches are equipped with pneumatic cylinder for clamping the tested product between the tailstocks
  • cycle start is done using the footswitch
  • manual mode can be activated by the footswitch
  • AC type of current, or optionally HWDC or FWDC
