Aug 01, 2021 I started with an Rong Fu (the real one, not a clone) RF-45 benchtop mill with square column, power downfeed on the quill, 12-speed geared head (the motor was two speed). I insisted on a square column to ensure consistent alignment after repositioning the head. I can't imagine dealing with a round column mill/drill
Mill - square column vs round, best NEW mill under $2000? Apr 14, 2005 Heaven help you if you need a 1" drill and then an 1/8" milling cutter on the same part. With a 5" spindle travel and a 6" drill in a 2.5" long chuck plus the depth of the hole, it just won't work.

Sep 13, 2011 Sep 27, 2007. Messages. 7,674. Sep 12, 2011. #31. For the most part the only debate in this thread is due to the fact that most round column mills will lose their center when they swivel if you have to loosen the head to raise or lower it, where a square column mill can be raised and lowered and not lose it's alignment with the workpiece.
Mar 12, 2015 Thanks. Yea it is much more of a mill-drill than a traditional mill, which is what I need due to budget and space constraints, plus I have primarily hobby aluminum projects in mind. The seller is asking for $700, but my other option is the harbor freight mini mill (Grizzly X2 re-badge) for about $500.
Oct 27, 2017 All that work and you still have a round column mill-drill. The parts costs will be similar to a like-sized square column mill, and the installation troubleshooting effort will be the same or worse. Even if you keep the acme screws and just do a 2-axis with manual Z (quill or head), items 1-6 above still have to happen.

Sep 04, 2009 Rong Fu square column is a respected machine, and worth the investment. I am not a mill/drill fan due to the issues with losing adjustment when raising or lowering, and loss of rigidity when extending the quill. More knee mill options: Bridgeport Round Ram.

Feb 02, 2016 Comparing the two machines: KC-20VS = 308 lbs with a square column. PDM-30 =772 lbs with a round column. So the pdm-30 is significantly bigger and will be able to take heavier cuts, but if you have to change the height of the head in the middle of a job you will have to do something to find where your zero is.
