Gage Block Introduction - How To Use and Calibrate Gage Blocks

[@borisdorofeev5602]

Good video, very clear explanation with no unnecessary additions.

[@brucewilliams6292]

Thank you for the video and the series. I have had an on going debate on the use of light oil to wring gage block; this video let me settle it finally!

[@MitutoyoAmerica]

You're very welcome, and we are glad to hear it!

[@emislive]

​@@MitutoyoAmerica using WD-40 was informative and actually reassuring: you don't need anything fancy to do the job, just a thin film of light oil. I had been wringing dry. Beyond the knee-jerk opposition you knew to expect, it might not be the best for those who don't keep steel blocks in a low-humidity environment. WD-40 is basically kerosene with a penetrating oil that's volatile enough to evaporate, plus fragrance. This might leave the blocks vulnerable to corrosion if not used often and the oil evaporates away. I would love to see you use more WD-40 where appropriate, if just to irritate those with an irrational aversion to the stuff. Thanks for the educational metrology content, good thorough authorative information can be hard to find on this topic.

Worked in Metrology until I retired. Thoroughly enjoyed the video; thank you.

[@MitutoyoAmerica]

Glad you enjoyed it!

Great info video👍 👉The “Wringing” technique was something new for me💯

[@osamanour2619]

you are amazing your way of clarifying every tiny detail thank you very much

[@herbiemitchell9156]

Brilliant video thank you. Where on earth did the subtitles come from? They may need some work.

[@rafihussain]

Great videos. What's else any body want other than this

@@MitutoyoAmerica he has a mail bag, send him a couple and you never know it might just pop up in a video

[@MitutoyoAmerica]

He's not a "shill" and does not want to be contacted by metrology companies. We respect his efforts to remain impartial.

[@Yeah73415]

I can respect that.

[@dannypatino3895]

do you have like a pdf procedure of steps you sued to calibrate the blocks

[@rodneybame]

How often do the blocks need to be verified or calibrated?

[@Arcticroberto9376]

This is often a question of storage conditions and frequency of use. I'm comfortable doing it every 2 years, as our products never need measured to the tenths. Often when you send them out for calibration, they will give you a recommended interval for calibration.

[@YoucaNShine]

Superb explanation sir.

[@MitutoyoAmerica]

Thank you!

[@josephmufdi4564]

Wow! My head is swimming. I see some older gauge sets have a little container with some substance in it. What is that?

[@GuyFawkes911]

please make a video on how to handle steel gauge blocks properly to prevent rusting, deterioration....

[@davidflack6430]

NPL have a good practice guide on the care and use of gauge blocks. Download for free from www.npl.co.uk

[@raymundo99]

It it acceptable to use the oils from your fingers to get them to wring together?

[@MitutoyoAmerica]

That's an old school method, particularly the oil from around the forehead or nose. While I can't recommend it, I have heard that some people use it successfully. However, there is concern about the acid level causing rust. If you do it, be sure to clean it off promptly when done.

[@Widge_1]

Excellent information. I have just picked up a set of secondhand Mitutoyo gage blocks, and are interested in the use of the wear blocks, could you explain their use. Thanks

[@ericandersen2590]

They are used on the ends of the stack so that you are taking the measurement off of the wear block as to not scratch the other blocks...then over time you will only have to replace the wear block.

[@hawks9142]

You know you've made it when an international standard is set because it's convenient for you

[@markdavidstrode4]

How about showing interferometric calibration at japan which is used for Grade K? I've seen the Mitutoyo Gage Block Interferometer for sale in the Japan catalog, it is not listed in the US catalog-every government has export restrictions for its good stuff.

[@K0stur]

How often should gauge blocks be calibrated?

[@MitutoyoAmerica]

Thank you for your question. For calibration cycle of any gages, everything is depending on following items: • Is the gage main master or secondary master for calibration • What is the use and storage condition of the gage, (temp & humidity, dust etc.) • What is the tolerance of the gage and the process that you are going to use it. If you need guidance for this you can visit Recommended Practice - NCSL International ( ncsli.org/page/RP ) and buy RP-1: Establishment and Adjustment of Calibration Intervals.

[@knowledgepower4808]

Great teacher!

[@almaxie342]

I think it is the van der waals force that holds the blocks together.

[@mflewis1]

Interesting that in the video the word is spelled as both gage and guage.

[@chrismate2805]

Flat surfaces....."Clinging"......."Wringing" versus possible "connection": I found the "Wringing" aspect very interesting. Appreciate you explaining of everything in detail. I found it interesting you said a tiny bit of oillneyness(clean) may add to the wringing effect. Far from this I used rough "clinging" effect. I made 2x jaws lying loose in michinest vice, had them milled squared. On them I fit fasteners(variable) to hold objects I want to do stuff with. As I open the vice, due to layer of grease , I do not have the problem of the inside jaws coming loose from vice, it sticks, the grease solved the problem, "clinging". I just thought about the theory of wringing........ Currectly the best gage blocks are flate to a certain standard which will have ringing work good. Now this is at an accuracy that is not 100% flat to infinity-0000000... Out of this my theoretical question would be, say for instance in the future these surfaces could be get 100% flat(chemically/electrically, what ever method) to infinity 000000, what do you have in your hand holding two of these flat surfaces apart, and then join them at 20c: 1-100% dry. 2-80% dry 3-50% dry x-...or humid(clean, contaminated normal air, vacuuum etc). Y-..I refer here to immediate contact, not left over time. With all the above in mind, could you have a "connection" with a different meaning than "Wringing".................just wondering, and have a problem getting them off each other as a result.

[@hughmac13]

I don't think that the "flat to infinity" that you theorize is possible. Molecules are not flat; atoms are not flat.

[@ModernBladesmith]

@@hughmac13 that's not flatness. You're thinking about consistency. Ofcourse theoretical flatness is possible, but not ever likely possible with technology, however we know that anything is possible, so something could become perfectly flat, but the likelihood is almost impossible due to temperature fluctuations in different parts due to air currents and what not, but the problem here is something would only be flat for a mere flash of time, then uneven expansion on an extremely small scale (bordering atomic) would be bound to happen and its flatness would change to an imperfect flatness.

Mitutoyo ceramic blocks are ridiculously expensive!

anyone else pause the video and go download the book?

[@koenvangeleuken2853]

very clear, well explained. however the accuracy of the subtitles is horrible!!!

[@robert202]

Hello. Mine does not stick to one another

[@MitutoyoAmerica]

Wringing gage blocks can be a challenge. Make sure they are thoroughly cleaned. before you get started. When wringing the blocks, feel free to use some level of force as you slide one block onto another. Press them together while sliding.

[@eduardomeller6926]

I can hear nothing on this video, was it muted? can someone pls. Summarize what he sayin?

[@MitutoyoAmerica]

I would first try looking at your volume controls to make sure your volume is on and turned up. If you still are having issues with the volume, we do have Closed Captioning for this video. Hopefully one of these works for you.

[@hhahaha8666]

[@MindBodySoulOk]

still didnt show me how one is used.

[@timthompson468]

goofyfoot2001 Good point. I get the idea of how to handle and wring them, but I’m not sure how they’re used. I assume you use them to check your measurement tools in the range of a specific measurement you’re making. So if I’m using a micrometer to measure a one inch piece, I’d check it against a 1” block, but does one adjust the calibration to match the gauge block or just adjust the number to account for the error?

[@hughmac13]

In practice they're used for the calibration of gages, to check that your micrometer is accurate. In a more theoretical--though still practical--sense they ensure (as long as they're accurate) that my inch is the same as your inch is the same as the inch at Boeing is the same as the inch at GM is the same as the inch at NIST. And so on. Everyone's inch needs to be the same (± a very few millionths) so that the jet turbine parts that a variety of companies make can all fit together tolerably at the Rolls-Royce plant and then operate without blowing up and killing millions of people.
