I once needed a couple carbide endmills with a nonstandard corner radius. Before going to my EM grinder for a price, I did a deep internet search and found a company that provided EMs with whatever radius you wanted at very little over stock price. When I got them I was shocked to see the radius and reliefs hand ground. But after microscope inspection of the tool and then part inspection, they provided the radius I needed

I've noticed that saw arbors are often a little wonky. They tend to cut more on one side than the other when sawing in the Bridgeport. It doesn't affect the cutting but the lack of concentricity is noticeable. K O Lee expanding mandrels are terrifyingly expensive, though.

@swanvalleymachineshop

2 ай бұрын

Yes , they often have a bit of a wonky cutting motion . They need to be sharpened on a dead true arbor & mounted on a dead true machine spindle . 👍

my Dawson grinder does not tilt either, However there is a flat back side with a threaded hole, and I made a plate to mount my Themac7 on it, giving me a full tilt either way, as well as rotate and elevate. I have like 5 of those finger deals, 3 are micrometer adjustable. I need to lay it all out and figure out how it all works, I have 4 tubs of tools and hardware, and probably 200 wheels mostly brand new. I have a small machinist vice mounted on a compound angle stand, which is what I use most. 6 yrs, and haven't sharpened a machine tool yet. The CAD boys make this stuff obsolete, so I get it for a song. sometimes I am the only bidder.

The correct way to sharpen a cutter is to have the tooth being sharpened supported by the tooth rest which resists the force of the wheel. The method shown has the potential for the cutter to rotate thus causing a 'stack' in the old parlance.

Custom one off parts , i generally give a quoted approximate fixed price & stick to it .My hourly rates , i do not discuss on social media for various reasons , if you have to pay rent , machine & wage payments etc etc . As there would be quite a variation shop to shop and also internationally . All that you have to remember , custom stuff takes alot more hours including lost hours than small batch production parts but over time the costing margin hopefully balances out . At the end of the day , stick to you quoted & get the job done correctly no matter what . You will soon work out what your hourly rate needs to be . 120 to 140 is pretty common here . Cheers 👍

Thanks for showing this set up. Could you let me know what settings you changed for the secondary clearance angle, I couldn’t see any change in the wheel height or the tooth stop.

Nice one . I am still setting my one up . I have to make a lot of the tooling as it is unavailable here , hence some of my unorthodox methods ! Cheers 👍

Just looked at the first few minutes. I did this fifty years ago, was taught by an old guy, Tom Costello... Charts for cutting clearance? All you need to know for normal T&C grinding is that to achieve 1 degree clearance you drop your stop/spring finger 8.8 thou per inch of cutter diameter. Sin 1 degree is 0.017455, half of that, since you're calculating the angle on the basis of the cutter radius is 0.0088, as near as dammit. Anyone prepared to argue? Tables? Pffft! Now, the other thing is... The tooth you're sharpening is the tooth that should be supported. Not any other tooth, in the hope that division in manufacture was precise... It may not have been... Now, that may give rise to issues... Such as when gullets are shallow, with little room to accommodate a finger. The Cincinnati spring finger holder permitted the use of a "home made" finger made from a broken hacksaw blade. 20-25 thou thick, if you couldn't accommodate a hacksaw blade in a gullet... there was no gullet to accommodate swarf... I have, though, for reasons I forget, in 1978, made specialized repair reamers for aerospace use, where the tapered lead ran out to a gullet less than zero, where I ground a step parallel to, and behind the reamer gullet, to run my spring finger on, allowing me to sharpen a reamer whose gullet was reduced to nothing when sharpening was completed... It may have been a range of piloted reamers. '78 was a while back... Re the "8.8 thou per inch of cutter diameter per degree of clearance" to metricate that, it's 0.0088 of the cutter diameter per degree of clearance... And... With straight S&F cutters, your system's OK. What do you do with paired and handed S&F cutters? I used to do them on a common mandrel on one set, ensuring they finished the same diameter. with no measurement needed What do you do with staggered tooth cutters? And... On a tilting head T&C grinder, you can set your spring finger to centre height, tilt the grinding spindle. (not as simple as that, but it's bedtime...)

@swanvalleymachineshop

So how do you get it sorted with no finger indexer & you are waiting on that cutter for a job . If you had listened on the video , it was clearly stated that this machine still has to be tooled up . That means tooling that i still have to make as it's unavailable here . And another thing , what's with the smart ass comment about using tables . Does that mean you have never needed to use Machinery's Handbook or other reference sources ??? What do you think , we have every piece of correct tooling at our finger tips in Australia , get real FFS ! Thanks 👍

On KZread comments, If I hit the wrong key, I lose my post... Done it three times, I'm a stupid geriatric bastard. But you're incredibly thin skinned for a 'Strine... Basic principles... 8.8 thou drop for one degree of clearance per inch of cutter diameter, (or 0.0088 of diameter for metric) same thing, never step away from the grinder to look at a chart... Simple arithmetic, piece of piss! Isn't it? Call it 9 thou, 0.009 for simpletons... Stay at the machine, make money... Always... grind the tooth that's supported on the "spring finger" NOT ANY OTHER TOOTH. Who knows if the cutter teeth are regularly or irregularly spaced? You think you do? I never did... That bit me on the arse... ONCE! I did, though, fall out big time with a guy over reamer sharpening. their flutes were commonly irregularly spaced... I was proven right, he wrong, but...I did learn something from him, because he enunciated an assumption he'd made about something I was doing... Assumptions, eh? Like assuming tooth spacing's regular?... Last time I worked in a toolroom, we were talking about, but hadn't yet seen... facilities to grind helical tooling with "master helices" and air bearing workheads... Never used either... But even now, geriatric and with poor eyesight, I think I could use both/either... blindfold. Spring finger... An old hacksaw blade... Tooth rest... Something unnecessarily complicated and expensive... Wheel... Something that gets reinvented regularly, by newcomers to the business of wheels... We could talk more. Oddly... since throwing in the "blindfold" remark... I rmembered visiting a toolroom in the UK (1970s) where there was a blind guy running a T&C grinder. Think about it... T&C's formulaic... Don't reinvent it... It was a simple formula. A blind guy could sharpen tooling by feel, and by counting clicks to set his spring finger height, braille mics for diameter... (a bastard for irregular tooth spacing as you "know" ) Putting a radius on a cutter may have been a challenge, blind... I just cannot imagine setting up a radiusing jig blind ( slips with braille markings? GTF!) But! "my" blind guy on a T&C grinder was moving around and working with tremendous confidence. It was fascinating, and unnerving, talking to a guy who couldn't see me, the job he was doing, nor the finished product... but performed well according to his boss. And... weekend overtime, I've modified form relieved cutters to perform a task on my mill, using a Duplex toolpost grinder as a wheelhead, cutte mounted on an arbor between centres in my lathe, a home made spring finger set to height with my height gauge... A quotation I made earlier tonight (over drinks) to someone... "Perfection is not achieved when there is nothing left to add, but when there is nothing left to remove" I'll leave that with you. (find the source yourself) It's the KISS principle.

Max, where could I find a complete set of the "Fitting and Machining" books? My Google-fu is weak and I only found "Fitting and Machining" as a single volume at a few sites in Australia and none in the U.S. (where I live). I'm more than willing to pay shipping for a good set of books!

Fantastic video, Max, very useful now I’ve a TOS tool & cutter grinder. I managed to get an online copy of the Fitting and Machining book. I note that on page 147 it suggests offsetting the wheel by 1 deg to provide a relief, for grinding angles, silly question but I’m guessing if you dress the wheel you should do that with the wheel square to the table travel first? It only mentions dressing the wheel for grinding square or parallel surfaces earlier. Or am I overthinking as usual? Cheers!

@@swanvalleymachineshop Aah, ok, now I get it, so it’s to avoid grinding on the other side of the wheel.. thanks! So if you limit your travel to one side of the wheel you can stay square and dress, grind etc.. got it! I’m a bit slow.. cheers!

Hi Max, Looks like a diamond wheel on the grinder. Do you know what grit it is? Thanks.

All the diamond wheels i use are 150 grit , works well across the board . Anything that needs a finer finish i use a slow speed grinder with 400 , 1000 & 2000 diamond lap . 👍
