@chrismorris8695 4 жыл бұрын

For bolt circles, instead of calculating the angle of the last hole, add one extra hole and always set the last hole to 360 degrees. i.e., the last hole is a duplicate of the first. This eliminates the possibility of miscalculating the ending angle. EDIT: as GrahamY1970 suggested, I discovered that setting the start and end angle to the same value will indeed have the same effect as laying out a 360 degree pattern on my import DRO. So if you follow the tip I gave above, your DRO might actually miscalculate the pattern. BEWARE!

@greybeardza9197 4 жыл бұрын

Quite agree Chris. The (seemingly quite good) manual that came with my DRO recommended this method IF DOING A COMPLETE CIRCLE. Only use a calculated end angle if not a complete circle - either under of over 360 degrees. While I hear everyone's gripes about the janky interface, the reason it is so is to allow for different end angles - different to 360 degrees that is. Remembering to add one extra hole is in any case easier that trying to calculate the end angle when you are drilling 57 holes!

@howardosborne8647 4 жыл бұрын

Chris, you beat me to it. I was going to suggest exactly the same method of adding one extra hole to the input data. I fumbled my way through how to use my Sino DRO as the chenglish instructions were near impossible to decipher and this extra index method was what I arrived at by trial and error. The error being one less hole than there should be.😵

Hi Quinn! I have noticed (in this and previous videos) that manual movement in the Y-axis makes the drive a whining noise. I have a model 45 mill that has a similar drive for the Y axis. You have to loosen the gear drive between motor and Y-spindle, it needs 0.5mm (or something like that) clearance between the gears. If that play is not there, the motor of the Y-axis will always turn during manual operation, making the whining noise and making it more difficult to turn. Give it a try, you will see.

@farmersteve129 4 жыл бұрын

I would like to point out that although these cheap DROs are often sold with 5um or 1um scales, that only represents the "precision" & not the actual "accuracy". Take a look at the specs say Heidenhain Lida 477 - the accuracy is only +/-0.75um per 50mm & that's for a scale & reader that costs more per axis than a complete Chinese 3 axis system! Probably not a big issue for the majority of users, but can catch you out if you aren't aware & I have seen cheep systems out by as much as 0.25mm/50mm! Also remember that temperature will play a part as the scale will tend to expand & contract with temperature changes so will affect the readings too!

Hi Quinn - thanks for the good overview of the DRO. I recently bought a DRO with LCD, which is a newer version of the classic 7-segment DRO. Upfront information was a little sketchy, but I am quite impressed with the unit. Numbers are very readable and change colour between ABS and INC mode and turn red near zero. Hole pattern entry is aided by the graphic screen to assist with the data entry. Build quality is the same as the older units, so I can definitely recommend it! Keep up the good work - Peter

Excellent content! I recently replaced the DRO on my lathe. The original DRO used rotary encoders on the hand wheels. I had to constantly reset my zero because the rotary encoders didn't account for backlash. I replaced them with linear encoders on the carriage and cross slide. The best things is that I can switch between "Radius" and "Diameter" mode on the cross slide. In Diameter mode, after I measure the diameter of the part, I don't have to mentally divide the required cross slide travel by two to determine how much further I have to go. I can use the cross slide DRO to dial in close to the final the diameter directly, measure, and then sneak up on the final diameter. Life is good!

I also use the SDM mode to create more than 1 datum, so I can have up to 999 different datums as well as the ABS and INC mode. This is also a good way to keep track of different holes so that you can return for different operations and save a few tool changes (spot/drill/tap holes etc). And with the DRO I bought from China I am able to set my bolt hole circle to 360 and have it give the correct hole pattern without the need to enter the actual angle of the last hole or add an additional hole as mentioned in other comments (I think it also takes the centre as the 0,0 of the datum before entering the function and not from where you were before entering the function). These differences between DROs means it is always best to perform a dry run BEFORE actually making a cut if you are new to the DRO or haven't used it for a while.

On the physical dimensions of the rulers, you can get much smaller ones, which means you loose less travel. Or in my case, might be easier to install on smaller mills. But they are a bit more expensive. Very happy with my DRO. Extremely useful gadget!

Maybe take a look out for the newer ones with LCD. It's just few bucks more, but worth the money. I have both, the LED segment type on the lathe and the LCD type on the mill. The LCD version is way more intuitive, especially for such kinds of hole circles and such a stuff. I strongly recommend this DRO type.

But basicly there is no difference between the older once and this one with a display. But the useability difference is really high. Hole patterns for example are my more simple to manage, because the DRO will will show it to you on the display "as is". There is no cryptic messages as like on the older 7-segment once. Just setting up a hole pattern is dead simple, also because of the clear UI.

Great informative video! I am interested in adding one to my mill and had many questions and you answered them all! I watched about 10 videos before yours. Some of which I turned off due to lack of detail and poor illustrations. The use of split screen as an illustrative tool was very helpful. I also now understand how the DRO eliminates backlash problem. Awesome work. Thanks.

thanks, I know little bit more about my DRO. I have to find the book. I bought it a few years ago , and finally got to install it a few months ago , since I'm retired now.

Well. I am looking at getting a DRO .. watched this .. and went .. WOW!! While I HAVE run a mill with pre-sets on the tool holders .. it was so long ago we used paper tape for the program running everything. :)

I'm always so very impressed by the clarity and quality of your istructionals. You are a true teacher. Just a thought about the material used to demonstrate: Rather than putting a bunch of holes etc. in a piece of valuable stock (like the aluminum flat stock used here) have you considered using, say, a piece of hardwood? You could paint the wood to make it show up on camera best. You might even use some glue or double backed tape to stick a cheap piece of sheet metal to the wood. Dumb idea?? Thanks again!!

Great video as always, thank you Quinn. I am currently looking to buy a DRO setup for my mill, so this was quite handy. One thing I will mention is that at about 2:40 you do say "Typically the 1um scales are only a little bit more money than the 5um scales". Actually they are at least double the price. In fact the ones I have found so far have been close to treble the price, which is a shame as I think I'll have to go the 5um route.

I am from the shop of 1970 - 1976 & we had no DRO’s on any of the machines , yes we did it the old hard way. What will machine be first to get a DRO the mill or the lathe ??, thinking it will be the lathe and then the milling machine. Building the PM 1 steam engine with you and the DRO would have made this ongoing project easier for sure. Thanks for covering the feature buttons ABS / INC & Mid Pount centering features as I fight backlash in the positioning screws everyday. Great informative video - Thanks BB

Of the two, I would definitely put it on the mill first. DROs are “nice to have” on the lathe, but massively transformative on a mill.

@bobuk5722 4 жыл бұрын

Hi Quinn. I've never really understood the need for DRO's on lathes. On a mill I think the are much, much more useful. Thanks for the walk through. BobUK

@donmathias1705 4 жыл бұрын

I would suggest productivity on a jobbing centre lathe with a quick change toolpost and a solo operator is five time more productive than without one and accuracy is greatly improved. When you store tool numbers in your control unit every time you use that tool if you have not moved your compound slide or altered your quick change tool post, the size it will cut is right there. They are easily the best money you can spend after a quick change tool post. If I want to finish a bore to a fine tolerance and a nice finish, I take my last roughing cut to about 1mm smaller. Do a cut at around .65mm undersize, measure and then if it comes out .63 undersize I split that difference and take my second last cut. Check it for size and then take the final cut. It is so straightforward. I make small runs of gears for gearboxes, usually only up to ten parts at a time and a cnc is not in the hunt. Too much set up time for the bespoke parts I make. Hope that helps you understand how they can be an advantage. I came up the hard way with dials etc 45 years ago and am quite able to do it the old fashioned way but not if i had a choice. Just a simple thing, but diameters are displayed as their true value, dials are often in the radius value so not halving or doubling numbers on a continual basis.

Thanks Quinn it's something I've been wondering about, my chipmaster lathe has no dro and my s13 mill has only X and Y. So at some point I need to move the dro off the Schaublin and onto the chipmaster, then get something to replace it. Not something I've been looking forwards to. But as they are both in storage at the moment it is something I could do while they aren't in use. Also the Schaublin has an old school pretty expensive Dro so I'm also hoping that the travel available is useful on the lathe, it can't just be upgraded to 3 axis unfortunately.

Gee, Quinn.where were you three months ago when I installed a two axis on my lathe and a three axis on my mill? Your video did give me affirmation I did it right but, I could have installed it in half the time. Also your instruction on the use of circle and line calculation was EXCELLENT.! Thank for another great video.

my mill is intresting the base was made in 1918. it was converted from a horizontal lineshaft mill to a vertical knee mill with a head from tree milling products. I picked it up fully cleaned restored and repaired it and added a 3 axis dro. To upgrade the mill and because at some point in time someone lost the handwheel scale on the x axis. the dro is a very useful upgrade for any mill

@craigguinn5423 Жыл бұрын

Well, late to the party, but this got me started. I got X working this week, and Y today. Combo lathe / mill so Y was a challenge making spacers bolts etc. But didn’t need grub screws. Indicated within .005 and it works fine. I went with a hybrid ToAuto glass 1um and TouchDro box connection and software, so had to configure pin outs in the box. Haven’t had to re-make anything and scales worked first try. Still, a lot of hours in this project, but being retired allows for more complex projects. My old Grizzly will be much more accurate and versatile now. 😅

Love this one. Oh, Datum...used plenty in shipboard navigation. Anyhoo, need to figure out what to buy and fit to my Smithy 1340 I bought Dec 2020. I like that one but have to make darn certain the readers are correct lengths. I saw one lesser unit that only shows a readout but no extra "buttons" to speak of. The upside is the reader are magnetic and you can cut them to fit with a bandsaw. The downside is they really only show a plus or minus readout (linear) x/y/z.
