    Rongfu round column mill VFD install.

    I’ve got a feed system that I bought at auction even though it doesn’t fit my mill; price was quite good and I thought “I should be able to fit this up with a little surgery”. That’s my next mill project. But converting my wood bandsaw to metal duty is likely next in line. We’ll see.

    Oops! That was just fumble fingers. Should have said 1.5 HP. That would have been a game changer, for sure. Like when I installed my first DRO. That was truly game changing for me. Can’t imagine using a mill without a DRO now, although I did so for many months before installing that system...

    Rongfu round column mill VFD install.

    Made some brackets to support the drive package and the control box. Both of those will have key-hole mounts, so that the entire drive package can be removed as a unit by only disconnecting the motor.

    Rongfu round column mill VFD install.

    The 18 does have terminals for a braking resistor, but in my testing I don't think it will be necessary. I set the deceleration rate to 3 sec and it very nicely winds down the spindle from full speed. It's fast enough that in the time between poking the stop button and picking up the collet...
