BAP300r + PCD 1135 inserts (reduce shank + @

- Just a short video about attempting to turn down a 16mm 2-flute BAP300r milling cutter shank and then testing to cut some aluminium using my cnc router (rebuildt 6040) Video ends up with a crash since Y axis aluminium motor coupler did split in two.

Those PCD inserts are insane, awesome surface finish! ... there is always something to fix on a machine.
Thanks for commenting man! I agree, when I decided to go all in with 24000 rpm and 6000mm/min feed. I did not know what to expect, was prepared for shatter and bad surface finish but the cutter just went through like it was nothing.
To bad the motor coupler broke, but I was aware of the risk. The most annoying thing is that I was abouy to upgrade that motor coupler next week. In which I will move the router from the Ikea table I currently use as stand to my new cast iron stand I bought. So this was the final minutes of cutting before the dissasembly. Apperently the motor coupler decided to give up just at the finish line.
Anyways I have now orderd new inserts and some extra cutters in case this one got bent during the crash. Then it will be time for round two. With a new stainless motor coupler and the router mounted on a cast Iron stand
Thx for commenting.
That was awesome! I am looking to some sort of face mill solutions for my 6040 as well. I've learned a lot from your videos!
Insane work, Thank you for sharing your work on youtube with us!
Thanks man! 🙂 I will now upgrade the motor coupler that broke, then mount the router onto a 73kg cast iron stand I bought. Think it will be a very nice upgrade. New pcd inserts are on its way to Sweden. I will soon be back with more videos.
@@thechipwelder1253 Your cnc is becoming a monster, extremely rigid. Which couplers will you place? Rigid? I'm using the spider type. Your lathe videos are making me want to buy one, keep up the amazing work.
not very many machines this good on youtube keep us posted!
Damn that surface finish🤩
Nice video. I have a few of them cutters i wanted to turn down the shank to use on my 6040. you beat me to it. And im not surprised the coupling broke. The bigger diameter cutters have more tool pressure then smaller tools. Plus with the higher feedrates im sure that helped it fail as well.
Excellent work. Keep at it!
This was awesome! Can’t wait to work in the garage this week myself :)
Thx for commenting man! I have already ordered new pcd inserts. Will make a stainless motor coupler next time in the garage. Then it will time for round two. :)
@@thechipwelder1253 just try to make sure they are somewhat flexible (the motor couplers). Any deviation in rotation and misalignment axially between the motor and the ballscrew will increase the wear on the bearings inside of the motors, killing them prematurely, if they are rigidly coupled. Good luck!
Hoping you do videos again. Enjoyed the channel.
very good video..thanks for your time
Thx for commenting man! I apreciate it!
Are you planning to do any new videos?
What rpm did you run the new tool?
Hello! Do you need PCD CNC inserts?
You still working on this project?
Which motors did you upgrade with ?? In a past job we used similar cutters to what you have shown, they were brand name "tyrannomill". They were using carbide inserts however and we machined mostly steel :-).
I upgraded to Nema 23 425oz 4A motors and HBS57 Drivers. An ebay seller had a promotion last winter when they sold a kit of: 3pcs motors + 3pcs drivers + 3pcs 5m cables for a total of 239 euro. Not availible anymore though. It sold out quickly.
Tyrannomill sounds more expensive than BAP300r. The cutter I used was only 6usd with two inserts for steel included. But it seem to do its job.
Thx for commenting man
@@thechipwelder1253 I spent about 5 years doing hand programming of 3-4-5 axis cnc for tool and die work. The premium brand cutters and inserts are indeed very expensive. But the shop rate a decade ago was $125 per hour so that cost was worth it if it made things go faster. I bought a G540 from Geckodrives. Looking at these steppers here. NEMA23 570 oz/in 3.5A 1/4” Dual Shaft Stepper Motor (KL23H2100-35-4BM)
I wonder what kind of steel I just turned. Tried to google some but found hardly any information about modifying these cutters. SinceI have almost zero experience turning, it had to be some trial n error. Tried many different feeds and speeds but did not achieve any good chips. Feel free to comment on how I can make better chips turning this for me unknown steel.
Usually changing depth of cut is the key to chip breaking if feeds and speeds dont help, but that needs a rigid setup and a lot more horsepower, havent had to modify them much, but usually havent had any large issues, they arent usually too hard.
Thx for the tips man! I plan to modify some more of these cheap cutters. So I will try and experiment some more with the depth. I also was recomended by another viewer to buy another type of inserts. In this video I made one deeper cut. Result was very long ~1m / 3f rope like very blue chips. That was not what I expected. But perhaps it is kind of lika a threeshold. That if one will take an even deeper cut it will get better.
I had one of those couplers split on me before. They suck
Yes, I bet many experienced this issue. Should have upgraded long time ago. But as always, I am a bit short of time. But now I have no other choice than to mount a new one made of stainless. Actually already made one this summer, but I never mounted it. Thx for commenting man!
Ouch! Losing $50 on an insert hurts!
Two inserts + shipping cost me a totalt of 20 bucks. So not the end of the world. Worse is that it will take me a month to recive new ones. There is always a risk when pushing the limits. I have now ordered new pcd inserts. Will make a new stainless motor coupler for my Y axis. Then it will be time for round two. :) thx for commenting
Probably it’s some tool steel i guess, even the cheaper tools are made from pretty good steel. Better try to figure out what kind off inserts you have ( talking bout those DCMT’s) because the chip breaker is designed for specific material, and no matter how hard you try to break chips in tool steel you ain t gonna do it with an chip breaker designed for stainless for ex .
Try to make yourself a nice CNMG tool holder for roughing mate and get some inserts , using a dcmt for roughing and general aplications is just cruel haha.
Anyways, love the lathe and the rebuilt router, wish i had stuff like that 👍🏼 keep it coming
Thx for for the info man! What you say about the inserts makes a lot of sense. I will get the inserts you recomend. To bad the motor coupler broke on the router, but there is always a risk involved when pushing the limits. I was aware of it and was willing to take the risk to make a good youtube video. Inserts + shipping did cost me a total of 20 bucks so pretty expensive, but my youtube Chanel will generate ~100usd this month, so it is not the end of the world. I actually already ordered new pcd inserts and some extra cutters aswell in case this one got bent. I will replace the broken motor coupler with a stainless one. Then it will be time for round two. :)
@@thechipwelder1253 forgot about those pcd inserts, now i saw your reply and remembered i used a lot of pcd and cbn inserts but mostly for hardened tool steel and they work amazing, never was too preocupied about that mirror finish in aluminium to be honest, using small CCMT inserts and the leave a close to mirror finish and that is good enough for me plus the cost for them is much lower than pcd
Where are you? 👀
sucks your inserts broke, that surface finish was nice! Have you checked how flat it is on a surface plate?
Thx for commenting man! Yeah, especially since I was about to upgrade that motor coupler next week when I will dissasmble the router to have it mounted on my new cast iron stand. I was aware of the risk that it would brake but decided to take the risk. Wanted to make a cool youtube video. So I only got myself to blame. Price for the inserts + shipping was 20 bucks. My youtube Chanel generated ~ 100bucks so it is not the end of the world. Worse is that it will take me a month before I will recive the new ones. Thx for commenting. I will be back with pcd cutting round two.
I faced off booth sides of the aluminium plate and planned to check it on my granit surface plate. But when motor coupler broke just at the finish line I decided to go home instead. 😁
6:02 Your micrometer is broken, no way that diameter is 1 micron :P
16mm milling cutter with 1 micron stepped shank :D thx for commenting man!
