Title: DROs on a mill
Post by: Will_D on January 18, 2015, 01:59:04 PM

I am sure this has been mentioned before but:

Thinking about DROs on a mill!

1: Mill has a Knee and a Quill.
    Where is the DRO scale fitted? I assume to the knee as this is the main Z axis milling facility

2: The "Kno Knee" Mill like the X2 and X3. Again where is the DRO fitted? The cut is usually put on by the fine feed on the head i.e Quill

I like to use the DRO for fine adjustments (i.e. as kind of a depth stop during drilling, or for fine adjustments when milling), so my Z axis is DRO'ed on the quill.

I fitted a dial guage to my quill as it has only 30mm travel just an idea .

 My mill is fitted with a fine downfeed on the quill but I never use it. I know some folks do but I only ever use the quill for drilling so I fitted a scale for that purpose.

I always use the knee to adjust the Z so that's where I'd put the DRO if it were my mill.

Why not put them on quill and vertical knee to a 2 axis readout. X and Y to another 2 axis readout.
If on quill fit it right not off the depth stop as always seen.

You can drill with the knee.

You've said this before. It's on the depth stop because its only for drilling, not milling. As I said, I don't move the quill for milling. Using the knee for drilling is slower and more effort than moving the quill, I guess that's why they fitted a drill handle as standard on these mills.

I have it on the quill.
Knee is much too heavy and imprecise

Sorry its still a poor way Arbalist theres always movement in the thread and where its mounted, the easy way out no better than using a ruler with the error pointless.
