The company Meyrat SA, which operates in the field of high-frequency spindles, has extended its product range and is now offering a 30 mm-diameter spindle (MHF-30) as an operational tool for bar-turning machines. The increased performance of its motor has encouraged the company to develop a new frequency converter.
This converter provides a power level which is three times higher than before and is also lighter. It can control all the spindles in the MHF-22 to MHF-30 ranges. As it has multi-parameter operation, you just have to select the data set which corresponds to the connected spindle. The data set selected comes up on this screen each time the device is switched on. This converter is very easy to connect and is compatible with all kinds of power supply from 110 to 250 Volts in single-phase current regardless of network frequency. The new converter regulates the motors in an open loop, as each spindle in the MHF range is actuated by a synchronous motor. This technology allows the device to attain high power levels while limiting power loss. In order to save time and improve safety, braking action is applied to the spindles by the converter. The converter can be controlled manually on the front panel (start/stop, speed and rotation direction) or by a numerical control or a PLC via the D-Sub interface. The dimensions and mounting options are exactly the same as those of its predecessor, so it can be used as a tabletop module or mounted on the front panel or base plate of the machine.
