I love this video. I am studying to become a millwright and have done some alignments. I wish I would have found your videos when I was doing my first alignments...it would have been less stressful!

As aCNC machinist I set spindle position in relation to a hole in a part or, more often, a tooling hole on a part holding fixture (and some other co-ordinate positions as well) when setting up to run different parts. Your videos were well done and facinating and it was easy to relate to the concepts you were presenting. Your company looks like it does well at providing an important service to many industries,while at the same time appreciating the contributions of each employee. I am impressed!

Thanks for asking. Bar sag can be measured by mounting the dial/s on a piece of rigid pipe. The dial/s are set to zero at 12:00 and turned 180 degrees to 6:00.

Cd, thank you for responding. Perhaps we were not clear enough. Mili is latin for 1/1000th. A milimeter, is 1/1000th of a meter and 20 milimeters would be 0.7873". We could have been clearer, however we were using the term mil to represent 1/1000 of an inch. In this expample, 20 mils=0.020". It is approiate to use mil in this context. If you buy a 3 mil garbage bag in the USA, the thickness would be 0.003". I hope I have cleared up any misunderstanding. Again, thank you for your response.

Mils has been arouund for awhile. I aligned many large Gensets. I prefer to measure in mm. A few of my fellow technicians that started to do alignments were getting it totally confused." mm" is milimeters which is metric,"mil" is one thousands of a inch. Fairly easy concept once you conduct a few alignments.

Aldhamin, thank you for asking. We made the brackets for teaching dials. They incorporate our laser kit chain fixtures and are not commercially available. You might try A-Line Manufacturing in Texas as they make a very similar bracket. Thank you.

@AcoemUSA 11 жыл бұрын

Hey Dimtt2, I am so sorry for this late response. I was reading comments and came across your questions. 1. Yes, the validity rule applies tor face dial values as well. 2. While bar sag will impact the vertical dial result, sag does not affect the validity rule as the dial and the point of contact both turn true circles. Bar sag merely causes the circle to be displaced downwardly.

I hear lots of people in various shops say "mils" for "thousandths". It's just common slang, and it can be confusing, especially when you work in both inches and metric. But it's more accurate than saying "move it over just a scosche" or "it's off by a hair"!

@clymnt 11 жыл бұрын

I've been doing alignments on rotating equipment for quite a while and mils is the term used in that field, especially with laser alignment. I will add everything I do is English measurement based, not Metric. Doing other forms of precision measurement using mics, calipers, indicators, etc., a form of thousandths is used in most cases. Though, they do get interchanged depending on whom you're communicating with. That's been my experience, anyway.

It must be a regional thing. I've heard mils used in machine shops as a synonym for "thousandths" for fifty years, but us folks in the south don't know anything about machining. This is a very cool video, and extremely useful information. Thank you for posting, and don't mind the nit-picking know-it-alls.

I don't get the total validity rule, surely it is stated wrong. What if the motor is misaligned 100 in the horizontal and 20 in the vertical? Surely its supposed to be left + bottom = right + top. Can you clarify?

@magip355 7 жыл бұрын

Nope he got it right, if the dial reads zero at the top, left + right = bottom

@bugfeet73 5 жыл бұрын

This is great! What I wonder is could you not put the indicator on a magnet stand and just rotate the shaft? You could read at 6 that way -- nothing would be in the way. Why have the indicator mounted on the shaft so it rotates for the reading... I don't get that... Note: I'm dealing with round stock sticking out of a lathe. Thanks!

@paulh5049 Жыл бұрын

The point of taking readings with the dial attached to one shaft is that you're trying to align them, i.e you are trying to get a relative position reading between the two shafts. If you were to measure with your indicator attached to the base and reading one of the shafts, you would only be reading the runout of the shaft, and not its position relative to the other shaft
