Discovering the VFD – This Old Mill

Previously the spindle motor could only run at full speed in either forward or reverse, and if you wanted to change the RPM of a milling operation, you had to change a mechanical gearbox setting. To be clear, using a VFD doesn’t mean a mill’s mechanical gearbox can’t be used or won’t be needed.
