BIG KAISER Digital Boring Head! Amazing CNC Tool! 

Great video. Presenter's enthusiasm helped make the technical information easier to grasp. Thanks guys!

Really good video. Quickly shows a ton of information. This is what I love you for. New technology. Not just following the way it's always been done. Not just saying "good enough." Shows you know your stuff and have tried different approaches, but without showing the mistakes. I like that you're willing to show you do make mistakes, but basic stupid mistakes that we all make from time to time I don't think you have to show. Keep up the good work.

I like how your cinematography is maturing! placement of subject, depth of field. Not only are you doing great machining and manufacturing, you're making really good looking videos!

Wow, impressive stuff John!!!!!! You've got the three pillars of a great company covered now... People, Products, Processes. Great Video.

Very cool boring head, I like how you showed all the steps you take for consistent accuracy.

wow Its midnight in Australia and I have work in 4.5 hours but Digital boring head too cool Thanks John

I told you when you got your first HAAS with the Renishaw you would love it and this is proof. Glad it is working for you. John

I have been CNC milling for over 25 years, and we have found the 3 point internal micrometer's to be the best and easiest method. On another point, some years back I used some some drills made by Dormer, (not sure if proper name now but we nicknamed them one shot drills), these drills produced holes to a few microns tolerance on size and roundness. Thus we did away with reaming and boring. These drills produced holes to take carbide inserts, which didn't need brazing. I love the video's, I even learn or sometimes relearn a few things.

Used to cut a lot of 4140 with those kaiser bars. One of the best boring systems I've ever used.

That’s cool. Multiple bore with same size is now easy!!!

John, love your videos. I just purchased EWD-254 last October. I have the OD turning adapter in a test trial now. These heads are awesome, accurate, and reliable. I am now looking at 3 point mics to go along with it.

Totally Grismo'd the QA John :-) Also thanks for introducing a new tool (to me), the Diatest split ball gauge.

Brilliant! PS: For thermal isolation on the gauges, put a piece of silicone tubing over that center section. Presto, thermal isolation. Thank you, thank you (bowing). 😋 PPS: I wish you guys were located near New Orleans. You have such a great positive enthusiastic attitude, which makes for such an enjoyable environment to work in. Kudos to you!

Love this video. I'm going to share this with my boss

Oh man, you're starting to look like a real machine shop.Good for you.

Nice. We have a Wohlhaupter Digital boring head at work and it is so easy to use. We only do one thing different first turn on the screen and zero it out than loosen the clamp

You keep using concentriciry, both in this video and the podcast, but I think you mean cylindricity. Concentricity is to another datum, where as cylindricity describes the roundness and straighness of hole. Great video though. We've looked at the wuhlhaupter digital boring head for similar reasons in the past.

7:39 You forgot to say "Boom"......just kidding, good video.

Thanks for shearing. I'm no machinist but I find you videos so fun to watch. Full of facts and enthusiasm. Even if the titel has the word "Boring" in it...

I really like that intro!

I don't understand everything you are saying but I love the enthusiasm.

There are boring heads with integrated motors and wireless connectivity now. So you can read and set the relative diameter from your controller. One of the tricks is to set this diameter accurately, then cut to be slightly below target radius. Then do in-process automated inspection, calculate the remaining material to be removed, then do a relative offset on the automated boring head, and cut the final shape. Finally do final in-process automation somewhere (after each hole, or after a series of holes, to reduce time changing tools). This usually makes holes really well located and really to spec in terms of radius (usually 1 10th). Check for example Rigibore ActiveEdge series. I am sure tho others might have similar products.

Some people (quite a few actually) are suggesting a 3-point bore mic. If you get one, it should be in addition to one of the 2-point bore mics you already have, not instead of them! The reason is that no single method of measuring a hole can determine all forms of out-of-roundness. 2-point bore mics measure the diameter, and there are plenty of non-round shapes with constant diameter. If there are an even number of lobes in a constant diameter non-circular hole the 2-point bore mic will show error, but won't show an odd number of lobes. A 3 point bore mic will show error in all even and in 3-lobe cases. It will miss 5 and 7 lobed cases though. So you'll still need the gauge pins as a go/no-go. And of course the gauge pins measure the smallest part of the bore, so if the bore is conical they won't detect it while the bore mics can.

Man I wanted to see it cut! That is one cool ass boring bar!

Neat technology!

You really should look into "three point inside micrometers" !!! Super accurate and easy to use.

Thanks for share.👌

Sooo cool!

Really neat technology. Have you tried any KSEM carbide tipped drills for doing the holes? They are balanced cutting forces so you don't have tool deflection, the holes should come out on a consistent size and would cut at least twice as fast. You also might could eliminate the pre drill operation.

Whaaaaat? No digital indicator with tolerance/max/low setting in the bore gage? :)

Nicely done John! ATB, Robin

Look up rigibore active edge. It does wireless adjustment.

I prefer a digital gun mic to measure holes. They have three contact points and are more consistent than the ones your using. In the end I'd recommend an air gauge for final measurement as any run out will show more easily. That's how we check hydraulic cylinder walls and hydraulic valve holes.

I should show my customers this video... SO THEY KNOW THAT PRECISION BORING IS NOT AN EASY JOB...... ESSPECIALLY WHEN EXPENSIVE ONE OF A KIND PARTS HAVE TO BE MACHINED THAT YOU NEED THE RIGHT CUTTING TOOLS, SEVERAL MEASURING TOOLS , TIME , CRAFTSMANSHIP AND PATIENCE!! So....that releaves me.....😁😁😁😁

Once upon a time, a believe Mori made mills with a U axis to do exactly what you're talking about at 7:45

They make an automatic boring head controlled by the cnc control. It just cost as much as a cheap cnc. But it does let you do crazy stuff, because its capable of tapers and facing . search D'Andrea boring heads

Just curious if you got unhardened plates to start with then mill them close to final to save on tool wear, then get them heat treated and finish with the boring bar, would the cost savings of starting with unhardened steel and less tool wear offset the cost of heat treating the plates mid way?

Great! Now you start using the right tools John! In my opinion you should defenetly try more european tools. Greetings from Germany

Hi John, quick question: How does this toolmeasuring device work? Pros and cons of a internal toolmeasuring?

Great job ,what is the end use of these plates?

Look into Brown & Sharpe “intrimik” best 3 point ID micrometer there is and throw out that bore gage

Awesome work, I wanted to ask you, what operational system do you use on your machines??

That's some pretty tight editing, the intro particularly.

When adjusting your boring head, or any tool, your final movement should always be tightening or pushing on the tool to take up backlash. I noticed when you went past your desired adjustment, you then backed off but it didn't show if you then tightened again. Always back off further and then tighten back to your position. I don't know how tight the boring head is, probably not going to cause you too much issue but it is good practice.

Thats badass! you have really come along way on those fixture plates over the last couple years. Next up is ID grinding right? :)

Dang it! why do you always post a video on something I'm about to do myself... do you have spies in my shop? great video!

I wonder how a jig borer would fit into that kind of workflow...

Have you looked into air gauging?

A similar Komet Bluekom 2 is 2 grand , just the head , you need bars,inserts and the basic holder aswell . They won't let you down , but it's not easy to justify one .

I would love to visit NYC again!! I went there over Christmas (made a cool video about it!), and can't wait to be back! We went to Top of the Rock, Chinatown, Little Italy, and even Casey Neistat's studio haha 😎🕶

are you using a carbide boring bar?

work this tool good with high-grade steel .??.. Thanks. PS: special to this material: WNr. 1.4571

want making perfect depth hole need to using Moore jig grinder to finish it. :)

This video is very boring. Ha ha! No, seriously, I am just preparing to do some boring head work for the first time so it's great to have John give me the low-down here. Great stuff!

When talking about the pin gauges , did u mean roundness instead of concentricity ? Isn’t the whole always going to be concentric to itself

How Deep you go with the Boring head not to touch the bottom ( you have a smaller diameter -Like a shoulder/ counter bore for the thread)?

It looks like your Tormach 1100 plate will fit in my Super Mini Mill - just trying to figure out it the t-slots line up.

Shouldn't you turn it on, take more of the reading, and THEN loosen the lock screw? If it moves when it's locked/unlocked, and it shows a cumulative reading, will it show the movement it experiences while the power is off?

Are you making plastic injection molds?

What about reaming?

Check out air gauging.

Would Iscars SUMO drills not give you the tolerance as well? I do believe they give an H7 fit.

Hi John, nice video, always seen them in the Big catalogue but never researched them. Ive an unrelated question, whats the sub bed on your Haas? is it purchased or have you fabricated it? cheers

Where can you buy these?

All those measuring tools when a simple bowers micrometer 3 point with a checking ring is suffice.

It would be nice if you could mix an air bore gauge to the digital boring head so the boring head could check the hole after the cutting pass and automatically adjust itself and recut if necessary. Boring and QC for every hole! All you have to do is take the human out of the equation and you would achieve perfection!

@ 10:22 ... random lion!

Jig Boring Machine

I like the fixture plate, but I don't know why it has been anodized for. Wouldn't that adjust the flatness, instead of it being simply ground and left alone? Precision surfaces like CNC Machine tables are left alone.

loud andf clear here

Would be nice to have ability to adjust it via WiFi ;) directly from g-code

How much was the boring bar?

Intro music?

John, automatic measurement and adjustment is already here. One example @ ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-FU8WSB8B__M.htmlm54s

u should turn it on before you unlock it

6:37 not trying to be a dick, but choking up on the torque wrench like that will not give an accurate torque on the bolt. torque wrenches should always be held by the handle. Choking up on the wrench actually over-torques the bolt.

hmm, was expecting wireless control and the head going to the set diameter by itself

Is he flying these fixture plates to Jupiter?

buy an air gauge and the master ring gauge, its a lot faster.

Oh boo, and here I was excited that somebody had made a motorised, remote controlled boring head that could e used to bore multiple iameters without having somebody to muck about with it.

no bucks, no buck rogers.

I want a job at this place I'd piss it 😂 I work with fucked tools do thousands of bores to +- 0.02 m/m using an imperial boring bar and some bowers mics no need for fancey expensive tooling that's no doubt going to get smashed up once somone drops a bolock and runs it in to the job!

Do you actually make parts for a living or just schill for certain company's. All your stuff looks new and unused.

Step 1. Throw that Haas in the garbage

Not first!

...that isn't what wysiwyg means...

como hablas, hablas y hablas y hablas. y no muestras nada. solo hablas !!!!!!!
