    Default Lathe DRO with tool #

    have not bought a new DRO in a great many years.

    Got a job coming where I'll use several tools, back and forth, on my 15" LeBlond servo shift.

    Is there a quality lathe DRO that lets you set up several tools and switch back and forth?

    Far as I can see all the decent modern DRO systems have multiple zero setting memories which will probably do what you want. My old Sino system, a lower end workshop grade device but perfectly serviceable for all that, claims 100 zero memory slots. Doubt if I've used more than 10 on any job.

    Be as well to check the mechanics of setting and the zero identifier display before buying. Mine has a proper dedicated number window and uses a single button to select the zero location. If you want to change things it lets you simply select the appropriate axis and directly enter the appropriate number. Which suits me. I generally leave the beast in absolute co-ordinates, move to where the zero should be and fill in the noughts. Entering offsets and using relative co-ordinates always seems to have too much error potential for my tastes.

    My Acu-rite DRO203, Fagor 30i, semi-antique Sony Model ??, and antique Acu-rite Master MP all have tool memories. The DRO Pros units I installed at the local high school robot shop have tool memories.

    Ok, great. I this is a standard thing then.

    If $ don't scare me away, I will go with Acu-rite. I put an Acu-rite on my 10EE 25 years ago. It broke after only ten years. I sent it in and they repaired it - no charge. Made a loyal customer out of me. I've since put them on three manual mills.

    I have had a few similar experiences, for example with Busch & Müller bicycle lights. It has exactly the same effect on me - I will keep going back.

    Yep, we have Acu-rite 220s displays on a couple lathes and they do have tool offsets. With the exception of some old Heidenhain stuff at home, all our DRO's have been Acu-rite and the only ones to give us issues were 40 years old or better.
