Single-lip cutter grinder - Details and uses

I have had the Shars version of this machine for over a year sitting idle due to a combination of my on going machine shop projects, coupled with the useless instructions that came with the machine. You have single handedley filled a huge void to those (myself included) needing some basic instruction on the operation of these machines. I sharpened two end mills last night love the possibilities. No turning back now. Thank you very much, Steve

Can you do a video on how you set up and grind the radius on the nose of a tool? i went through the SO Manual but just cant figure it out :-/

good job

Stefan, Thanks for your video, it is very good and extremely helpful. I am looking at locally buying a used Franz Kuhlmann SU2 cutter grinder at an attractive price. It appears to be a clone/cousin of the Deckel SO. Do you have any opinion on the quality/function of the Franz Kuhlmann SU2? Thanks for any feedback you would be willing to share. Regards, Larry Snell

Plzzzz make video sharp ballnouse end endmilll tip radius how tu use

Interesting video! Where are the wheel mounts (wheel adapters) available in Germany? I could not find a source.

Really great detailed video! I recently purchased one of these and I love it. I do have one complaint, however. It seems that the wheel rotation is actually opposite of what it should be. When sharpening isn't the best practice is to be moving the abrasive into the cutting edge, not away from it? I did a set up using the inner part of the grinding wheel (it's harder to do; a mirror helps) but the results seemed better.

Your not joking about Deckel being expensive, I just Googled it and even the manuals and catalogs are in the £65~£95 range

hmmm - holder mount looks much like an equatorial mount from a telescope

Hi Stefan, I know it's a while since you produced this video but thanks. I've just purchased one from a UK supplier and as you say, the instruction 'pamphlet' is useless. Doesn't even explain how to take the wheels off. 45 minutes spent watching your video is a great help...........I shall go and practice!!!!! Thank you.

you can get a used deckel for about 1k. if you look. iv seen them on ebay. great video bro.

Comprehensive and well explained. For sharpening single lip engraving cutters though, I use a home made cutter grinder that has a, swash plate mechanism for relieving.

So Stefan: I found one of these which I acquired for $200. Low mileage with attachments.
How lucky is that? Now I only need to get it into the basement. Can I count on you for help?

Stefan, have you actually removed the pages with your d-bit grinder modifications from your website? The URLs seems to lead nowhere right now. I'm receiving my d-bit this week (german/chineese Optimum GH 20T) and was hoping so much to follow your modifications to tune it up....

Are knife edge diamond grinding wheels available for this machine? Thanks for the wonderful work you do!

You have no idea how much this helped me out! Just picked one up and will be doing a video on it soon...

stefan - i acquired a shars clone recently. a noticeable difference on my clone compared to
the deckel is the vernier for the radius offset. Mine is calibrated in 1/4" major increments and
.050" minor increments. i am probably going to stick an indicator on the side of the divider head
to measure the radius offset. what are you using to measure radius offset? thanks for all the
informative videos and advice. i'm a hobbyist with a PM932 mill, a Covel #15 surface grinder,
a South Bend SB1001 lathe, and a bunch of metrology.

Question - can you dress your diamond wheels with the diamond dressing stone? It sounds like a bad idea but if you can't then that means you can never true your wheel which doesn't make sense....
I'm assuming you can, as the diamond wheels aren't solid diamond but diamond powder embedded in a medium of some sort.


Your insight would be greatly appreciated!

Thank youstephan I just bought an Alexander tool and cutter grinder this has amazing content for us new to tool grinding thanks again

Do you ever grind the flutes?

I have had a want for one of these for years , as well as a 3D pantograph the size of a Bridgeport milling machine. In tech school we had both and both had stenciled (Property of US Navy) on them. I had figured in a few years I would have ran across these two machines and traded for them , but still have not found either one for a trade. I have seen this grinder on Amazon for around $600 but I had much rather do some sort of trading for a used one😉👍

Thank you! I very badly want a cutter grinder but haven't had the exposure to them to know what kind, and its good to know the cheap knock off is still a good tool. I was disappointed though when you said the helical grinding attachment was useless as I was waiting for you to say something about that the whole video. Is it that it is not rigid enough to grind new flutes in a carbide blank or is really that heavy an operation just to touch up the edges on a dull end mill?

In my watchmaking school we have about 6 of these machines, they get a lot of use. Best machine, after this video I won’t be looking fo a Deckel just pick up the Chinese version.

you know im going to ask about the red dot...

Just purchased one of these from Warco. Loving it. Sharpened loads of drills and end mills. Yes its expensive but i've saved at least £200 already. Nice video Stefan. Thanks.

Price please

Extremely helpful video. I have been buying new drills and end mills but I've saved the old ones and would like to put them to use. Also I suspect that with the right grinding cup it might be possible to sharpen gear cutters, which I have zillions of.

Some years later, I actually bought one! Now this video makes a lot more sense, has helped me immensely. I never got the hang of hand-grinding lathe tools, and the prospect of sharpening end mills, and making my own single-lip cutters is very exciting. Thanks Stefan!

Fyi, mine is a UTG-U2 of Chinese origin, purchased new in the UK. I can't find a cheap source for Deckel collets though, some cheap Chinese collets out there but shipping cost is horrendous. Fortunately, I have an ER11 chuck on a straight 8mm shank I can use... Might make my own custom collets, now I can make the cutter for the buttress thread...

Hi, Amigo
I just bought a tool grinder like that and I am told it's has U2 collets what can you tell me about this type of collets, or do you know any web page that can tell me more about them, as f.ex. is it a collet who have more than one name. thanks for sharing all these videoes and your expertice it is much appreciated

Thank you!

I find your videos very interesting and informative . Do you have details of the lathe tool accessory for the Deckel SO with maybe photos and dimensios as I would like to make one. If you have a video on that accessory it would be great.

Where to find these resin coated grinding wheels?

Hast du auch so ein Video zu einen Spitzen gravierstichel z.b. 0.2 mit 30 grad . LG

What do you call the aluminum oxide wheel with the resin bond on the outer layer that you show 18 minutes in? I am trying to order one but don't know what its called.

My SHARS clone doesn't have a RED DOT or any other identifier that I can find. Where do I set the INDEX rotation when using the setting finger to align the flat on the DBit?

Nice Video 👍

Stefan, It is recommended that you put a clearance angle in where you need to go at least 5 - 7 degree above horizontal when you grind the face of the cutter, without it you don't have a real cutter clearance angle (Freiwinkel of 5-7 degree for Metal Cutting Tools). 35 years ago I had to teach Toolmaker Apprentices how to use this Single Lip Cutter Grinder. Today most of the new generation of Machinists don't even know that this special profile cutter exist. You can actually grind a spherical ball shape onto the cutter. With this Grinder you can produce an unlimited variety of Milling Cutters. It is sad that many Teachers today don't know the capabilities of this Cutter Grinder.
I know you explain it to best to your knowledge, so please don't be offended by my comment. Thank you,

Dear Stefan, I think you are the only one that can help me that I know have huge knowledge. Following you I bought a beautiful toll cut grinder, made in Italy but I don’t know the name. Now My problem is that I can configure out what kind of collet need, is not 5c or U2 or any other that I know, I surf internet but there is an ocean, difficult, please those are the dimensions may you know what kind of collet are thread look 25 mm - 1 mm pitch a Length 121 - cone od 32.54 - I can’t find 😢, please try to help me

When you refer to bucks you refer to Euro's yes??

Ohhh... You said fuck in this video. Du böser Junge.

After seeing this D bit grinding application I purchased an angular adjustable tool holder head and plan to add a mounting bar on my small ma ual surface grinder. Thank you.

I'm planning on being able to sharpen corner radii or ball end mills

Stefan is right the Deckel used ones are completely overpriced and do not always have the milling attachment with them...there are more worn out in the market than not worn out ones and still they cost a fortune because if someone don't have a good look that the ways are protected by putting some clothes on it when not using or a plastic bag over the arm these ways are quite small and if they get dust all the time they are worn out in a short time noatter if it's Deckel or china the china clones are quite good I prefer building a diy one because I got the arm for nearly nothin brand new 😊

Thanks

Hi Stefan, I am having problems accessing the photos of the work you have done on your grinder. I have the same model. Thanks
