    Issues with A Milling MachineMaterials Required to Do The ConversionThe InstallationProgramming The VFDI recently purchased a mill/drill milling machine patterned after the popular Rong Fu model. I soon found that there were some issues with the machine that I felt could be corrected with the three-phase motor/VFD conversion. Because it is a three-pulley, two-belt drive setup, with the center pulley acting as an idler with both belts on it, changing the spindle speed requires removing and changing the position of both belts. This is very tiSee more on library.automationdirect
