  • DRO's

    Looking at getting DRO's for a mill. What brands do I need to stay away from.

    Thanks

    It all depends on what you're looking for. What kind of quality and accuracy will you be satisfied with? There are several that I, personally, wouldn't want, but other people are perfectly happy with them.

    Acu-Rite, Heidenhain, Anilam, Newall, are probably the top brands. Mtutoyo and Sony probably fall into that category too.

    There are also some pretty good Korean and Chinese imports.

      I think mitutoyo is the cheapest of the name brand stuff. I found this place

        I have an Easson and really like it...I have a Sino on the lathe, it is OK, just different, maybe a bit less user friendly but has more features..

          I am using a Fagor (made in Spain I believe) which perhaps doesn't have as many features as others, but the repeatability is amazing.

            Look up JENIX. It is Korean (top quality), scales with accuracy as good or better than the major brands, and about their 1/2 price... They have kits to fit most brands.

              I put Fagor Dro's on my mill also, very rugged, accurate, built to last, about mid range on cost.

              Yes, built in Spain not Asian and the level of features depends on the model. The cheaper ones have numeric readouts with the usual built in functions, there are models with LCD screens and fancy function display.

              I called the US service line with a question on using one of the built in functions and ended up having a half hour talk with him on a variety of subjects, none of this 90 seconds and out stuff. They where very helpful and the service rep told me that they keep parts in stock for anything they have sold for over the last 20 years if a repair is necessary.

              You don't hear of Fagor that much in NA as much as other brands but they are equal too or better than most and cheaper then a lot of them. I liked mine enough that I put one on my lathe too.

                I have a SINO on my lathe and a Grizzly on the mill. I cannot speak to *accuracy* of either though I use both daily. I've grown to trust both. Both have served me quite well up to this point. I had no choice of DROs when purchasing my lathe; the SINO came with the lathe. To be honest, the SINO was the first DRO I ever owned thus my knowledge of DROs (brand included) was scant at best when I received my new lathe. I made a conscious choice when purchasing the DRO for my mill. The Grizzly has large illuminated numbers and supports 3 axis. Installation was new to me thus difficult. I have insufficient experience to offer names of less desirable DROs.

                All in all, both mentioned have done what I've required of them.

                          This DRO question comes up ... all the time.

                          The truth is, I have yet to hear from anyone that the DRO they bought is junk.

                          DRO PRO'S get a lot of positive feedback ... but as many have eluded, the units they sell
                          appear to be the same chinese units sold elsewhere, but with really good support.

                          My opinion ...

                          If your ordering for your company .. buy name brand
                          If it's for your home machine and money isn't an issue ... Use Dro Pro's
                          If money is tight (like me) ... buy ebay Chinese (<$500 for 3 axis with glass scales)

                          again .. JMHO

                            I agree with Mike Amick on this one. The command buttons on the cheap ones looks so similar to the ones on my DROPros version that I suspect the same programming goes into all of them.

                              I bought a 2axis for my lathe. 198.00 (I had a 36.00 discount) and free shipping from china. the first DRO I bought "off shore" was 5 years ago 3 axis about 500.00 and 125.00 shipping. The first one has been used and abused and never missed a beat
                              Most all of the off brands I believe are the same and most likley made in the same factory If you want to deal with a off shore vender and dont need hand holding I don't see any reason to buy a $$ DRO that is identical two a 2 to 3 hundred china unit. I will get the 2 axis unit next week so I will find out if cheap works for my hobby use
