Thank you so much for taking the time to record, edit and post your video. Was looking for this exact type of video before making my purchase of a similar face mill.
Cheers
Thank You. Regards: Larry
Thanks for letting me know about the mimi-mill. Very cool.
Thank You. Regards: Larry
Thanks Larry for the input. Very helpful. Looking at getting one. Liked your talking.
I've used the end mill a lot and it works well. I'm sure you'll be satisfied with the performance. Larry
Nice to know you are busy happy with it so far, I too am looking forward to getting one....thank you.
Good Luck......Regards: Larry
It's rather belated, but thank you; I have a similar mill and a similar cutter in the mail. Having seen your results with it - and having the same use case in mind - I'm now excited to have mine.
Glad I could help
Great video. Thank you for sharing. Cutter works great.
Thanks for your comment. Regards: Larry
Very helpful for a beginner like myself thanks from Australia mate 🇦🇺 👍
Thanks for your comment and Best Regards: Larry
Highly informative! Thanks for posting this video.
Thank You. Regards: Larry
There you go.. looks good man..👍
Very impressive for this mini mill. I have the same mill and will surely be purchasing one of these!
Brandon Tscheschlog what is this for a mill i would like to get the same one
Thank You. Regards: Larry
I thought that face mill performed pretty well. Price is great, and having the extra inserts is nice too. I like your vice. Do you any info or videos on that? Thank you.
Rule of thumb the more flutes the finer the finish 2 and 3 flute mills will remove more material but leave a rougher finish
Nice. I like your vice hold down clamp. I use a vice very similar.
Thank You. Regards: Larry
Great info ! Thank You Larry!
Glad it was helpful. I understand that Banggood also sells a better grade of inserts. Another viewer commented. Regards: Larry
bought the 63 mm its about the maximum a stock grizly g0704 can take
glad to hear its running smooth , i havent used it yet as i was kind of worried about the plastic gears inside the machine
Good Luck........You should be pleased. Regards: Larry
I tried one of these facemills with a larger machine. 2mm deep cuts in a single pass without a problem.
Yes.....I've also been taking deeper cuts and doing some general milling. Nice cutter.
I found with my cutter the inserts were at different heights.
It will cut even better if you get your head trammed in a little better. It is not quite parallel with the bed, as the cutter trailing edge is not leaving any kind of marks. So your cutter head is slightly tilted to the left.
Thank You. Regards: Larry
Yes, I spotted that too.
please dont forget that you can touch up those inserts and remove the wiper flat on the bottom--I have a video but will redo it in the morning. Those 1604 inserts the big ones 16mm have a huge wiper flat thats scrubs across the surface multiplied times 4. You can use many methods usually just a diamond knife lap from EZLAP to remove almost all of the wiper flat--my video explains it..
Thank You. Regards: Larry
Hi folks. Skip forward to 5:30 to actually see some action. Feeds, speeds and depth of cut would have been useful but it does look a nice bit of kit. BobUK
Thanks for the tips!
Larry
That face mill is now coming with 4 of the better grade Blue Nano inserts. The bag of inserts you got for around $9 are the cheaper ones that have gotten some poor reviews. The Blue Nano inserts run closer to $20 for 10. So, be sure and test with the chaaper inserts and see if you get the same good finish before counting on the replacement inserts for something important

John: Thanks for the info. Regards: Larry
WE ALL ARE GETTING THE IDENTICAL CUTTERS.. I make my own universal arbor though. mine came with a morse which I threw out immediately.
Thank You. Regards: Larry
sweet,ni ce video and a great price for a face cutter,.....
Ray: Thanks for your comment. Regards: Larry
Hi I bought a very similar 50 mm face cutter from China for use in my Optimum BF20L milling machine ( very similar to others sold in the USA under different names) The milled Surface finish was poor ( even with a cutter depth as low as 0.01mm) so I bought a packet of 10 new inserts. Didn't improve it at all. Cant say I am impressed with the 50 mm face cutter head. I get much better surface finish from the 25mm head with two pointed shape insert cutters which you showed. I couldn't see any point in keeping it as I would never use it so sold it for half price.
Odd number of inserts won't chatter as much. I'd like to know the limits as far as DOC and feed rate. You might be impressed with my homemade cutters
Good to know.......Thanks............Larry
Hello from Norway. Thanks for the video. I have just order me one of that, with blu nano insert. Carl
Carl: I think you'll like it, especially with the better inserts. I may order some myself. Regards: Larry
Thanks Larry, I have the same endmill and mini mill. I was not happy with mine but I think maybe I was running it too fast and trying to remove too much.
Try using it for finishing large areas, only removing 0.005" or less. Run it slow at maybe 500 RPM or less. After all, it's 2" in diameter. You should be able to see the inserts clearly as it rotates. Thanks for your comment: Larry
Thank you Sir!
🙂
Thanks for your comment. Regards: Larry
Great cut and another awesome video. What rpm were you at? Definitely going to pick one of these up😀
Probably about 400 RPM. I haven't really tested with different RPM speeds. I just initially set the RPM where I already knew it would work fine, considering I just ran the feed very slow. Thanks for the comment: Larry
Mine has 1 insert sticking out further then other 3. So it only cuts by one insert.
I don't use it. I made my own flu cutter and it works allot better.
I've heard that from others. I've checked and mine is perfect. Yes, fly cutters are nice for finishing. I use mine all the time. Regards: Larry
Thanks Larry. Very helpful. I timed the feedrate (ipm) at 3" per minute.
What was your depth of cut (DOC)? My guess is 1/10" (.100") or less.
Was the Width of Cut (WOC) = 1-7/8" ? [aka overhang not cutting = 1/8" ] ?
If these guesses are correct, then the Chip Load / tooth was .002", the Hp was 1/2hp
and the MRR was a bit over 1/2 ci Appreciate any feedback.
Paul: My memory fails me at this point in time. I'm sure the DOC was just very minimal considering I was making a finish cut and the IPM was very slow. I never meant to use the face mill for typical milling operations. The step over was probably little or nothing, using pretty much the entire cutter diameter.......so yes; probably about 1-7/8". Thanks for your comment and best regards: Larry
I found the same very good cutter for the price😊
Jason: I think they're available everywhere these and probably continue to me made from the same manufacturer. I like mine and have used it off and on since I purchased it. My mini mill seems to handle it quite nicely. Thanks for your comment and best regards: Larry
Hi mate what inserts are you using from Banggood ?
Thanks for the video can you comment on the model of your mill
littlemachineshop.com/products/product_view.php?ProductID=3990
Not being a know it all at all, but when you start with a poor machine then it's even more important to follow good machining practise, you should run at the proper speed and use the proper feed, slow to be safe doesn't work there are speeds and feeds for a reason. Then you should always feed against a solid jaw, or a stop. Hope the tips help, 93 tool maker since 1940.
Richard: Thanks, I can use all the help I can get. Thanks for the comment. Regards: Larry
Any trouble getting the appropriate replacement inserts?
Hello Larry, I saw your video, and I was very impressed, that I also bought the same tool, saw your experience I wanted to ask how much you do the cutter (RPM) and the depth of how many cents, I assume that in the video you work on a piece of steel, if you have also used it on other materials, like aluminum if you can tell me also for this type of metal the rpm of the cutter (RPM) and the deep pass. Thank you
Noe: I've only used the cutter on mild steel. I only purchased it to make finish cuts of a few thousandths of an inch at a low RPM. I have other smaller diameter end mills for removing larger amounts of material. I can usually remove easily 0.030" with my 1-1/4" 2-flute end mill. With the face mill, I'm only interested in removing 0.005", but I'm sure it could remove much more. The final finish is sometimes important on a wider piece of steel, so the 50mm face mill works nice for those occasions. I'm sorry that I can't be more helpful, but I don't usually watch the RPM, but instead just do what feels good. It's not my nature to push the depth of cut, etc.. I'm usually in no bit hurry. Best Regards: Larry
These face mills work better at higher speeds as they have carbide inserts, carbide running slow gives a poor finish both on mill and lathe alike, still a good tool to have for what they cost. Once your inserts get a bit dull you can use them for roughing out and save the good ones for finishing
Speeds & Feeds are a guide to a general purpose , if you get that , every tool has its sweet spot it can be way off from its rule. 👍👍
Thank You. Regards: Larry
I forgot to mention that they work great with only 1 insert as a finish fly cutter, they are far better balanced than a typical fly cutter and you hardly notice if it has 1 or 4
@@incubatork Interesting Thanks Larry
Do you mind a link to the cutter please ? Thank you sir.
They can be found on eBay, but the sellers and prices change like the wind, so a link wouldn't be valid for too long.
You can find them all over the internet and from banggood.com
Is there a face mill like that which fits on an MT5 morse taper? I have seen these for R8 but can't find anything for an MT5
I'm Very Sorry that I don't know the answer. Since the R8 arbor is only attached to the mill head I would assume an MT5 arbor would be available. Regards: Larry
If your not cutting on the trailing end of the cutter, in both directions, your a little out of tram correct?
I think tram was okay. It would help to lock the Y axis. Tram could also be a "slight" problem. Thanks for your comment. Larry
This face mill has a major flaw. 1 flute is shorter than the rest. Put it on a flat surface and you will see
I may take it over to the surface plate and give it a look see
@@larrypoindexter9351 What did you find out?
@@rogermaury7722 I'll try and look at it tomorrow. Just a couple minutes on the surface plate or maybe I'll just put it in the spindle and check it with a dial indicator. I'm sure it's not perfect and the inserts are not adjustable, so it is what it is. Most things made in China are imperfect. You get what you pay for most of the time. Larry
@@rogermaury7722 When placed on the surface plate all the inserts are dead on. Within 0.001". That's the smallest feeler gauge that I have. I'm sure that things could be off if checked with a dial indicator while mounted in the R8 Spindle, but then there would be a lot of stuff in play. Larry

Just found your video. It was great Thanks. What end mill are you using and was it auto feed or you ? I'm looking into getting a mini mill. Did you get it from LMShop ? (the link you showed).
Tom: I think I purchased from China location, but at the time they were being sold by many sellers both in the U.S. and China. I do have a power feed unit on the mini mill and I wouldn't be without it. I think I did purchase that unit from LMS. Best Regards: Larry
Ever use a face mill with a shank. I have a hard to find taper so im limited to what i can fit into a collet holder uo to 3/4"
Electro: I'm sorry, the only thing I use for the larger size end mills and face mill is the R8 shank. If you only have a 3/4" collet, then I expect your probably very limited concerning the tools cutting diameter. Regards: Larry
@@larrypoindexter9351 how big do u think i can cut with a 3/4" collet? Width, depth before it spins in the collet
@@electromechanicalstuff2602 IT WONT
@@jaysilverheals4445 ok thanks
Larry that certainly is a nice enough finish, it would be interesting to see what the finish is on cast iron, do you think it would be even nicer? one thing I did notice was in the video there seemed to be some wobble where the cutter head attaches to the R-8, can you set up a dti to check the tip of all 4 inserts on revolution to make sure they all zero out, or another test would be to move the table instead and leave the cutter stationary, just curious,
Walter: It runs dead smooth, even at 2500 RPM. I'll check with a DTI tomorrow and let you know.
So it must be a face that is not important and has not been ground,
I'll run a DTI across the inserts in the morning, just for curiosity.
this video is good . i have questiom what tipe of bit i need to a good finish on aluminum also this face cutter is MT3 or MT2???
The mill spindle is R8. The insert that came with the face mill seems to provide adequate finish on aluminum. Thanks for watching, Regards: Larry
@@larrypoindexter9351 thanks for you videos and for answer my quiestion
@@larrypoindexter9351 i like to ask you im new on this i have a smithy combo lathe the classic . the mill uses mt3 or mt2 i want to buy a colletc set and mill face cutter but i dont know what i need . i look on they website but no info for this model thanks
@@m0ntr0s0 MT3 Shanks are common and available at many suppliers, as are collet sets. Larry
Hi metal guys i use these face mill with the same inserts from China (but golden so Tialn coated i think) since over a year now and the finish is okay (My 60mm DIY Fly Cutter with a 16mm steel insert holder leaves the better finish) but the moment i take a little deeper cut ( lets say 0,3-0,,5mm) the 550W and 70kg mini mill comes at his limits ...makes noises and cuts not so well any more ....really deep cuts i cant imagine with such a head ...is this my fault or the machine or the head?
Thank You. Regards: Larry
Did you convert to power feed on that mill or did it come with that ?
Berkeley: Yes I added a power feed unit to the X axis. A nice unit can be purchased from LMS (Little Machine Shop). I've owned several of them over the years and think it's definitely a good investment. I have problems with my shoulder, so it's almost a necessity for me. Regards: Larry
Awesome video... What exact milling machine we're you using?
Bill: It's a typical mini mill. Here's the link: littlemachineshop.com/products/product_view.php?ProductID=3990
i wonder if using lube would reduce the swirl marks or make it smoother?? anyone know?
I'm pretty sure that would be impossible. If you tram your mill table perfectly in both directions and also align the end mill inserts perfectly then you should get a decent finish. On some larger face mill it is possible to align the inserts. No matter, I think end mill marks are just going to happen. Regards
yes - but 'lube' gives a better finish on nearly every other material known to man - why not with metals? for example wet sanding glass and plastics, etc etc - i'm pretty sure it results in a better surface finish when turning metals on a lathe ... i guess it functions by reducing surface temperature and surface tension itself
Coolant can crack inserts because of the heat differential. Alot of inserts are ran dry
What inserts are you using on this tool?
Nothing fancy.......Just the standard inserts that came with the tool. I understand there are better inserts available, but I've never purchased them. A lot of people have made mention that some others do work better. Regards: Larry
do you have the link to get the end mill?
I'm sorry, but I've lost track. I'm sure it was most likely "banggood.com". Those face mills are available everywhere. They've been very popular on both Chinese and U.S. sellers. Search Ebay and you'll probably find what your looking for. I'm sure the price has probably gone up, but I'm sure that they're still very reasonable. Regards: Larry

At what rpm were you running the tool?
I'm sorry, but I don't remember. Probably at a low RPM and Feed.
what's the name of this sort of machine?
Thank You. Regards: Larry
Its a milling machind you can carve/mill material (mainly metal ) flat parallel square amd to dimension
Thanks for Your video Larry! I am using the same type of vises, one having 35 mm wide jaws, the other having 50 mm jaws. Your vise is larger I see. Nevertheless, where did You buy the clamps holding the vise? I'm searching for better clamps to my vises. I also bought the same facemilling tool, from the UK. I think is was a good buy.
Stefan: The clamp hold downs, I made myself. There a fairly common design, and I made the same type for several different types of vises that I have. I think I might of found some plans on LMS's web site and I just adjusted the dimensions to fit the particular vise for which they were needed. Here is one link, but there are probably others. Regards: Larry
littlemachineshop.com/images/gallery/Drawings/ScrewlessViseClamps.pdf
Thanks a lot Larry! I just compared the holes of the 2" and the 1 1/2" vise. The 2" has 6 mm holes and the 1 1/2" has 1/4" holes… eBay....I bought 4 clamps from LMS some time ago, put the taps in the lathe and brought them all down from 8 mm to 6 mm....Anyway. I experience it as difficult to achieve a stable line up, square, of the vise in the micromill, a PROXXON MF70. The MF70 has a table made of aluminum so tightend the clamps hard into the T-nuts will damage the table I think. Nocking on the tightened and squared vise too easily move the vise I feel. Adding two extra blocks with adjusting screws to stabilize the vise regarding forces from the side with the holes feels like a lot of extra work.For clamping the 2"" vise to my minimill I still have some adjusting modifications to do. Hopefully squaring up and maintining square will be easier.Can You give any more advise?
Stefan: I too have a Taig Micro Mill which I use for small work only. It also has an aluminum table, which is not ideal. The largest end mill I've ever used is 1/2" and that's really overdoing things. The small 6mm screws and T-Nuts just can't hold very well with the milling forces exerted against them. Taig uses mostly aluminum parts, with the exception of the main frame. There Micro Lathe is the same way, but for watch and clock work they both do the job they are meant to do. I have a tooling plate on my Taig mill which has 6 T-nuts holding it. When you attach a 2 or 3 inch vise to the tooling plate using the fixed pre-tapped holes, things seem pretty solid. You can also add your own holes to the plate for special items; such as a vise or rotary table, etc.. Regards: Larry
Thank You Larry! Making a steel plate tightened by 6 6mm T-nuts to the alu table ought to be safe. Making the plate universal and/or dedicated for the vise is a choice. Do You have any video showing this tooling plate?Regards,Stefan
Stephan:
I'm Sorry, but I don't have any videos. I do probably have some photos. I'll try and locate them and attach a link. I bought some scrap pieces of precision ground aluminum plate that I found on Ebay. I think I found scrap sizes that I felt would work as is. One of them does fit the mill table almost perfectly. I used CNC to drill them and then tapped all the holes by hand. The one that fits the table, I made specific holes for several different vises and rotary tables. Regards: Larry
