Can you give me the contact to source in India...
👍
This video is better than the multi million machines videos.
Nice tools will research, thank you for this video it is going to make our project much easier to make. Lance & Patrick.
Thank you 👌
Why that happened? The cutting tool and workpiece rotates in same direction....😂😂😂
do we need to have c axis in our cnc?
No
So.... why spin at all, then stop when the tool comes in contact with the stock?! What am I missing here?
The holder is eccentrically loaded to vibrate the cutting tool and cuts the work piece in tiny amounts, thus giving a controled cut with lower broaching pressure.
I see that now - not sure why I didn't see this when I first saw the video. Thank you for commenting.
What is the benefit of the lathe rotating?
Oliver Masters I think it's just a result of the design, that is, using the axial component of the wobbling motion to do the cutting. Perhaps you can reach a higher cutting speed with rotational motion than normal broaching (purely translational motion) would allow?
12.10mm? you mean 13mm right?
twelve point one billion! because I'm megalomaniacal.
crazy, coming from a spline grinder, I like the wobbly concept
Tonnes of force required. The larger the job, the force required goes through the roof.
What is Twelve.Ten?!
Good

What kind of positional accuracy do you get with the internal and external broaching (what kind of runout)? What kind of tolerances for the shape on the external broaching?
You would just mill it if it was external
Owen White You would if you had a "C axis & Live Tools". Thats if you producing the job on a Lathe!
Owen White Not always possible. I want to do this on a milling machine to make small gears. It's impossible to mill those with anything larger than a 1/64" endmill for finishing passes. Ideally I would just use a hob, but I can't.
Not to mention that corners on an internal hexagon can't really be milled.
Can a manual lathe capable of holding a 2m workpiece give a tolerance of 0.01mm?
No. You would need to grind to get that kind of accuracy.
tubester4567 Actually I was not clear enough in my query. I have a 2.192 meter steel rod of 28.5mm diameter. My application requires a groove to be machined at some distance x from each end. The dimensions of the groove are 2.15mm wide and 0.7mm deep. This groove would be used to seat a snap ring. So I meant to ask, can a manual lathe machine a groove of the said dimensions + - 0.01mm?
Sandarpan Oh I see.....Yes, you can do that. You can either poke the rod through the chuck and leave the rest hanging out the back of the lathe (with a stand but be careful) or set it up with the tailstock if the lathe is long enough. (but you would need to setup the centre steady because the bar is so long it will flex/vibrate in the middle without the centre steady), but should be easy enough, keep the rpm's low. You can use a parting tool for the groove or just grind up a cutter by hand on the bench grinder. Your 0.01mm tolerance is a terribly tight tolerance for a snap ring but you can do it. Are you sure you don't mean 0.1mm? 0.1mm is equal to 4 thou, 0.01mm is equal to 1 thou. That's tiny. Anyway if you use the markings on the lathe (or the digital readout) you should get very close. I would probably just grind the parting tool to the right thickness you want (2,15mm) then after finding x wind in until it just touches the rod, then wind in 0.7mm. Should be very close. Certainly close enough for a snap ring.
Depois da broca que abre furo quadrado, isto é muito interessante.
Where could I get It sir?

That Blog very useful for me for my work. thanks for sharing such kind of information. twitter.com/SuperCutting
porno music!
This is tool porn after all ;)
Man, I bet those things cost like 10 bucks.
Sorry, but I want to slap the narrator...
So, it's basically a rotating chisel? Kinda neat :)
because the spindle may not be lockable (no C axis) so you need a constant for the broach to work....i guess
Oh, I get it. I just don't see that it matters AT ALL. Whereas, not understanding numeric precision and tolerances DOES matter a great deal. I pity your supposed students.
No need to "educate myself". I teach Mechanical Engineering, you are missing my point, regardless of what you say about tolerances( I also teach that as a separate module and have no space here to begin showing you where your you've gone wrong), it is NEVER OK to say twelve point TEN. that's as bad as saying even twelve point one hundred. Its ALWAYS twelve point one zero, or twelve point one zero zero. (depending on the decimal places your want to work to. How are you not getting this?
I did not have ready access to a bar to put over my nines to show a repeating decimal, so I used "999..." to show that the 9 repeats forever but is less than 12.105. Another way to show it would have been 12.095mm <= 12.10mm < 12.105mm. I am completely correct on this. If you spend some time educating yourself on tolerances you will reach the point where you understand why you are wrong. No need to be an ass as well.
No. This is NOT the case in Engineering and Science. 12.10, is pronounced Twelve point one, or even (if you want to show resolution or precision of the measurement) Twelve point one Zero. Never, Ever , EVER Twelve point Ten. And as for your numbers, where the hell did you get 12.104999? did you mean 12.104? you've just argued the convention for two decimal places, then tried using a figure of SIX decimal places to prove your already invalid point. Did I read your post incorrectly?
12.10mm gives you information about the precision of the measurement in question. Due to the practical limitations of any manufacturing process, nothing is ever EXACTLY the size it says. The trailing zero lets you know the size is actually somewhere between 12.095mm and 12.104999...mm. This is fundamental to science and engineering.
John H who gives a flying fuck?go argue with your wife not someone taking time to make a video you lonely fuck
what is the price on a set of these broaches lets say square hexagonal torx polygonal broaches of all sizes small to big and the holder or holders if there are more of them with morse taper ?
That does occur when broaching through holes. A staggered progression often from a round, through square and finally to hex form in the one cutter.
My point is that twelve point ten IS meaningless. So is twelve point one hundred, twelve point thousand... Its BASIC maths. If you dont understand this, you should be not be in a toolshop.
Yeah they are Bloody Expensive, BUT, having looked at the website they do give you the option to just rent one, for short runs or one off productions, couldn't find a price for this, but i should imagine that it would be preferable to the high purchase price. Nice tool though!
The tool is at a slight angle
significant figures anyone???
Calm down there, Sparky. Nobody likes a grammar nazi.
Really? Math is universal..... It is Never ok to say "twelve point ten".... EVER.
Hi Amol, Yes you can fit the Broaching Head to a CNC lathe, we can offer the Broaching Head on various shanks. Please see our website 1mm-35mm A/F can be maintained depending on Material. You can broach Brass/Aluminium/Plastic ect..... Steels and some Stainless Steels. If you require any further info please contact me Cheers Nick
SOMEONE PLZ TELL ME HOW I GOT HERE FROM SEANANNERS :/
Then the correct term would be twelve point one zero. Twelve point ten is completely meaningless. Would you say twelve point one hundred too?
Neither am I. Im British, I work for an Italian company.
The rotation is used to oscillate the cutter... apparently...
Finishing of your tools and holder is great.
They're not American, they have different customs.
Then say twelve point one zero. Twelve point ten is never ever correct. you might as well say twelve point 100,OR twelve point one million.
Oh~!! This is Broaching...I have been misunderstanding...before..+_+;
12.10 mm. The zero represents a level of precision of 0.01 mm +/- 0.005 mm.
