Touring ZEISS: Learning about CMM and Metrology!

- Until recently, CMMs were typically only found in large factories but times have changed! We've seen an increasing number of smaller shops willing to invest in this technology--and for good reason.
The manual QC process has been the way manufacturing entrepreneurs have gotten by; however, with more people competing to secure work contracts, sending "bad" parts out the door isn't an option. If you're looking to level up your workflow processes or product quality, it's always good to be aware of new technology--even if you can't implement it right this second. Let's check out the different types of CMMs that Zeiss has to offer!

I discovered machining as an adult and I'm grateful to have found something I love that I can share with others. We hope NYC CNC not only makes you a better machinist but helps you understand and learn more about how to succeed as a manufacturing entrepreneur! 5 Reasons to Use a Fixture Plate on Your CNC Machine: bit.ly/3sNA4uH
As a metrology engineer who calibrates and error maps CMM's on a regular basis for a major aerospace company I can say these are great and accurate CMM's however.. User expertise is essential and not cheap. Also you need to budget for calibration and repair in your decision making process because a simple calibration with ISO 10360 in mind is very expensive and will have to be done annually in most high production volumes. We do ours at least every 3 to 6 months. Another thing "crashes" happen just like on your CNCs so count on it! You will be down for weeks. Depending on you location it can be difficult to find qualified metrology vendors to perform your calibrations. The cost just adds up quickly. Not to discourage you but I've seen plenty of waste because the user needs the confidence and expertise to operate and maintain a CMM. If you do buy do your due diligence on all makes and models that you deem viable. Customer service with Zeiss is good but there are others. Licenses for the software is another thing to consider do your due diligence with that as well because it is just as important. Sales folks for these companies do there best to provide accurate information but they are sales people ;-)
John are you really in the market for a CMM? I have a Contura G2 with the Vast XT head and extras. I might be willing to part with. Send me a e-mail and I will shoot you some specs and photos.
It was great to shake your hand. I was the awkward guy. I said I liked your channel and content and when you asked if I was in the trade i said "no, just a geek".
The touch probe was invented by English engineer David McCurtry
A good CMM is half the work. Checking a part to a print with proper GD&T is the other. If you have prints where dimensions are still in the +/- days, you are verifying next to nothing. You may be able to verify size but not location or orientation or even form sometimes. If you have prints with mis-applied GDT, especially my favorite datum precedent violation, it is futile exercise. The math behind how CMM measure is specified in the umbrella ASME Y14.5 standard. CMMs are getting super accurate but none of it matters if the prints defining the parts are not complaint.
I've been in that room many times. The Prismo is a show piece with sub micron accuracy over 500mm. I program and run a Contura with the XXT head every day. That place is like my playground. I head there when I need to research a new piece of equipment.
We have a Duramax on the shop floor and a Contura w/ RDS XXT head and it’s so much fun. I love the Calypso software as well.
Your Tour was Awesome. CMM automation and repeatability is marvelous with "geometric tolerancing" and ability to do sub-micron measurements. Thanks for supporting professional shop-floor tooling and equipment assembled in the USA/Minnesota. A "Spectrum" model is a great shop-floor CMM-tool. Respectfully, Thanks for the Shop-floor Tour!
Excellent tools, takes out the difficulty of measuring squareness, when reorientation in 2 D measuring.
Very interesting to learn that Zeiss have 'affordable' entry level machines and kudos for actually providing indicative costs! Garry did a great job of presenting the range and technology scope for each. As always, thanks John !
Wow! That flexible mount was awesome. 👍😊
Thank you, very interesting, always a great watch :)
Great video - thanks for taking the time.
This is perfect and simple and nice tour!
At work we machine columns and arms for their Horizontal Arm CMMs. Zeiss is a very cool company with a unique philosophy,
The Xenos is insane. Zeiss won’t even sell it to you (assuming you’re can even afford it) unless they inspect and qualify the area you’re installing it in. Massive foundation and isolation requirements, strict thermal and humidity level controls and it’s pretty much a permanent fixture, there’s not really any moving it around later. Basically have to dedicate its own room for it in the basement somewhere.
Learned a lot thanks for taking us on this tour you have a blessed day
Wherein John tries to convince himself he needs a new toy he can't afford.
Rocking the contura...great machine.
Really interesting for various measurements of parts
