Owing to their pulse width modulation, the MF generators feature automatic adaptation and a PLC to control the generator. With up to 8 programmable times with freely selectable power levels, even complex heating tasks can be solved with the PLC. A pyrometer can additionally be connected for temperature control.
In addition to general applications, MF generators are particularly suitable for surface hardening at low hardening depths (approx. 1.5 to 5.5 mm) and for brazing larger workpiece structures.
MF (medium frequency):
Typical heating depths: approx. 1.5 mm – 5.5 mm
Frequency: 8 kHz – 40 kHz, (2 kHz – 5 kHz on request)
Power: 1.5 kW – 1500 kW
Microprocessor controlled
The HF and MF generators rated 5 kW and higher are operated via the digital operator unit. This unit is used to input operating modes and parameters and to display target and actual values. Among other things, the display also serves to show the cooling water quantities as well as error states, such as low cooling water or incorrect adaptation. The generator equipment optionally includes a temperature measurement and control device, which is integrated in the PLC. Localized overheating of the component, for example at the edges, can be avoided by means of non-conctact measurement at the hottest place on the workpiece.
