The Best TOOL for perfect smooth surface! [Lathe]

- Do you need perfectly shiny and smooth surface without grinding on the lathe? Then use diamond burnishing tool for that. In this video I showing diamond burnishing tool at machine steel.
By combination right insert and diamond burnishing tool is possible to reach shiny surface with RA 0,2-0,3 at conventional lathe without grinding. This method is very useful!

please be aware that if you do this without coolant diamond graphitization will occur if the temperature rises above 500 C (or around that) . so you will lose your diamond tip.for this reason we use tungsten carbide and not diamonds to machine stuff that contains iron atoms
Same thing happens to tungsten carbide. It's just not quite as expensive as diamond is.
Carbon will always dissolve in hot iron.
Atoms 😂
@@chipcity3016 Yes. Atoms. That's how diamond erodes. It's also how tungsten carbide erodes when you hot-grind steel with it.
If you're going to grind steel, then use a wheel with no carbon in it. That's why we have Alumin(i)um oxide and zirconia wheels in white, pink, and blue friability grades.
Is anyone using/supplying CBN tips here? If so, how do they fare?
So to not use something that has carbon in it... you use something that has carbon in it
k, lol
Diamond burnishers! I use this for electro/mechanical probe areas on power gen turbines. 200 sf .006"per rev. Bathed in kerosene. I only load the spring. Gives a beautiful deep purple mirror.
I'd like to try this with a work hardening material. If I need a case hardened shaft without heat treating and subsequent grinding, it looks attractive.
This lapping would probably cause only skin hardening, it's not anything like "case hardening", and I doubt you could actually get any proper case hardening even by deep cutting material with a tool.
@@MrKotBonifacyif you case harden with induction could you then use the diamond tool for final finish?
@@firstmkb Edit/ correction - it's at 14:58 when diamond tipped insert is used, that one at 12:35 is CBN one.
Thats brilliant. Never seen this before. Thanks for posting.
Burnishing, very common on turbine, compressor ect shafts in area where Bentley Nevada and other vibration probes ride.
Beautiful finish. Nicely done.
Been familiar with this tool since 2008. But it has been around much longer. . It's called an Elliot burnishing tool
Did you watch the video?…that’s exactly what was in the box..🙄
Why didn't the image on the front picture not appear in the video? I thought you were going to do something with it.
Wow! Looks like a regular diamond tip for grinding wheel dressing.
I think it's the same
I would have thought it would be a highly polished semisphere, rather than a crystal with sharp corners (which is what dressing, particularly profile dressing, requires)
a link to purchase this tool would be welcome!!!!!
Rigidity and coolant a must to “rub” this finish in. Not happening on your bench top harbor freight lathe
Manufacturer of machine has nothing to do with finish of material. Maybe accuracy of size. If anything has more to do with operator of the machine, and how good they are at running it.
Absolutne brutalne :D A vidiet ze mas rad dokonale rezne rychlosti :))
What's actually happening here? Is it rubbing the surface smoothe or is it actually cutting?
Its’s burnishing. It’s not cutting, just rubbing surface. Diameter is same or little bit smaller (0,01mm). Surface is also hardens.
This technique also probably hardens the surface .
That’s insane!!!
What is the name of this diamond tool. It looks that it's not cutting, only rubbing the surface, correct?
You're right it's only rubbing, but when you measure the diameter befor and then you get 0,01-0,03mm difference
@@CzechMachining ok, so it get's smaller a little I assume, yes? But what tool is it, where do you buy it? Would be cool to try😎
@@zyndapp800 try to search for diamond burnishing tool. This one is from Elliott tool
@@CzechMachining Many thanks! I'll try to find one and test it, looks really cool👍
Not rubbing. Burnishing. It is not supposed to remove material, only compress it and distribute it evenly. Also it is absolutely essential you use this with some lubrication. They recommend oil or at very least a cooling water-oil emulsion as the poster is using. Also, please notice that the tool is spring-loaded in the toolholder. It needs precise force pushing it towards surface. I think I am going to get a diamond tip for dressing grinding wheels from Chinese online store and try this. What could go wrong?
how much do these things cost? cannot find a site that has the price listed
Easy peasy to make..👍
Nice work
do you know the value of the force pressure on the diamond?
There is spring inside.
este canal promete!💪
Wow, that is amazing.
how much were you removing on your diamond cut ??
It is 0 or 0,01mm on diameter. Depents on material and surface quality before diamond is use
Very cool. What is the material?
It’s S235 or S355
Thanks. Also, is the diamond tool spring loaded?
@@kendrom yes thats diamond tip
"proceed to touch with naked hand just after the processing"
nice but this is by no means an ordinary steel, looks like free machining steel
Thanks for that bro! Corrected. Its machining steel SJ235JR
You can burnish most common metals with the right tools, be it steel, stainless, brass or even titanium.

Burnishing?
Ooooooh, it be shineyyyy!!!! Noice! That's burnishing right? That means you have to rub against something to make it shine. !That's what she said!! LoL sorry, it's holiday time, ya kno?!
How's the RA after that beauty pass?
We got 0,2 - 0,3 RA
corner cutting is not posible use a cylindrial grinder there are ways round the corner problem it turns into a real perfomance diamond turning was used back in the war for makind high grade components You need a fast spindle speed 3000 rpm tip tool do just as well for practical perposes nevertheless interesting vid ttfn&tu
That's... a diamond-tipped BURNISHER?
Yes
@@CzechMachining Very, very nice!
Wont work on your mini lathe, you need lots of horsepower and rigidity.
😢
Interesting.
Shhhiinnnnny
buongiorno mi sono appena iscritto oggetto fantastico mi puoi dare link preciso x acquistarlo grazie
That long sleve revela at the end thooo yikes
PSA ist wichtig und richtig
"Yout"
I have never worked in my machining in my entire entire life nor do I know anybody who works in machining if you work in machining and you haven't seen a diamond bit burnishing tool before you should probably leave the industry
More like a grinder than a lathe tool.
are you sure it is diamond and not CBN? never heard of diamond (carbon) being used with iron in this manner for obvious reasons
pretty sure uploader has zero clue about what is going on in the video
Wheres the link to buy this?
If you have a Lathe to use one on then you have the tool to make one... Not being an ass just pointing out that you can be your own tool maker.
Easy peasy to make one…
@@PA-Tammy They have a pesetting spring tensioner built into them. You can't just stuff a diamond nib into a hole and run it.
@@johnhall8455 They have a pesetting spring tensioner built into them. You can't just stuff a diamond nib into a hole and run it.
@@johnhall8455 Where can I get the diamond tip? And what should the spring pressure be? Thanks
