I wanted to share with you some of the solutions I've found to be useful when it comes to changing tools in your R8 spindle milling machine, from the most basic to a push button powered drawbar!

For one who has been following home-built CNC projects for a long time, this is by far the most complete and easy-to-understand overview of tool changing on small machines that I have been able to find! Well done!! Thank you for sharing and for your excellent links!

Thanks for making this detailed series on your cnc journey

@hairyfro 5 лет назад

I got that same pin wrench. Painting it 2 different colors is genius!

@unclejo3 4 года назад

no idea what I am watching, but there was machining involved and new stuff to learn. Great video

@StripeyType Год назад

SUUUUUUPER psyched to build a similar system. I am just so over changing R8 collets. This also means I can have tool offsets in my DRO finally! wooo!

@crazybrutus1234 5 лет назад

That came out nice I'm glad to see more updates on the mill I just ordered a pm25mv and will be working on converting it as well I can't wait to see more updates keep up the hard work

@CraigLYoung 5 лет назад

You should put one of those aviation flags that says "Remove before Use " on the plug,,If you are like me, you'll be holding down the air button trying to fit a collect wounder why it won't go in.

@jqhartle 4 года назад

I feel like ive seen a little gemstone like that on other plugs... really cool idea for a diy power drawbar, anyone with a bridgeport, take note

looks awesome - thanks for sharing with us.

Very inspiring video! Thanks for sharing your project with us!

@kwk8363 5 лет назад

Very nice job, i was wondering, did i want classic ER style spindle or atc. Now i know - atc is the right way to go. Your video help me a lot, its easy to understand how it works, thanks Jeff

@warchild69ATtheZCR 4 года назад

Absolutely awesome, thank you very much! Totally makes sense and I have wondered for a long time how this system would work....

@CncObsession 4 года назад

Nicely done presentation. Very organized.

@kentvandervelden 5 лет назад

That's very cool Jeff! I saw you were working on it on Instagram, and it's fun to see all together. Next up, ATC! Best wishes, Kent

@PracticalRenaissance 5 лет назад

Thank you Kent! I love instagram for its ability to show little slices and progress of a project before the whole scope of it is revealed on RU-vid! I think my next step now is to play the Tool Library game and make sure to get all my offsets *perfect* 😀

@TMCmakes 5 лет назад

@@PracticalRenaissance before you go too far down that road, have you considered something like automatic tool offset (similar to tool break check)? i have a library defined and am now looking at going to something like this instead. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE--D6H9mpUu0I.html this video makes me want to put PDB on the list above tool setting though. any chance you'd share the model for the custom piece you machined for this project? i'd like to 3d print one and start making plans based on this video.

Well explained!

very good video..thanks for your time

@BellyUpFishGarage 5 лет назад

Your viewers must have cleaned ebay out of the cylinders! :)

@gangleweed 2 года назад

While it does work perfectly I prefer the electrical solution using a 24 volt linear thruster.....click on.....click off, no compressor needed......if you need more force just use a 4:1 offset lever advantage. I'm not a big fan of the Tormac system design of a power draw bar that applies a huge force to the collet to overcome the force of the Bellville washers mainly to hold the tool in the collet as my opinion is that the collet relaxes when the tool is gripped whereas you need more force not less to grip the tool shank.

@dieselmakesmehappy 4 года назад

Sweet! Once you go power drawbar you never go back.

@grntitan1 5 лет назад

I’m impressed. Nice work. How much tweaking did it take to get it working that smoothly?

@adamdebowski2037 3 года назад

I've gone ahead and ordered a 4in cylinder & have access to about 120 psi (~1500 lbs) - Been trolling youtube for all the PDB videos I can get my hands on, and some are saying you need north of 2200 lbs. I'm using the TTS quick change system on a PM30-MV and often run a 3/4" shear hog pretty hard. You ever use tools that big successfully with no tool holding/retaining issues? Or would you move up to some kind of higher force system? Awesome video, as always, thanks for sharing!

@aom8422 4 года назад

very good man thank you

@davidkal9083 Год назад

Hi there! Can you provide some info for the cylinder you used? or some another one pls

@michaelbrocato7535 2 года назад

Thanks for sharing this video it has help me understand the concept. I do have 1 question can you explain the air setup , other than the big green button ....is that a 2 position 3 way valve? I see a shutoff of course and the blue line must be the input supply right ? Can you in detail go over this section of the setup

@MrCrankyface 3 года назад

So if I understand this system correctly, the drawbar is always threaded into that special collet, and then you change what the collet is holding basically?

@PracticalRenaissance 3 года назад

Yep!

@billcodey1430 5 лет назад

You have been busy.

@toolanddie9789 3 года назад

Do you remember the thread pitch of the tophat you made?

@pauldevey8628 5 лет назад

Wow!

@toolanddie9789 3 года назад

Can only seem to find a 4" bore with 1" stroke on ebay.

@joels4208 3 года назад

Nice Job! Just curios... I am looking to buy a new vice and was wondering if you are using a 4" or 5" vice?

@calebburnett 5 лет назад

Very cool. I may have missed it but does that air cylinder use a standard 100ish psi or is it regulated down?

@PracticalRenaissance 5 лет назад

Great question! It's just 100psi shop air.

@davecox900 4 года назад

How would i go on, mine is a belt drive my belt runs round the top of the spindle

@stevemaynard7397 4 года назад

Hello where did you buy your prints to make all the main cnc conversion kit brackets from

@miguelcastaneda7236 5 лет назад

how much deflection does that give collum i know on a full size bridgeport i can lean and deflect .010

@boboconnor1403 4 года назад

Have you had to adjust it at all???

@kermitfrog1897 4 года назад

Can you post the specs for the air cylinder?

@toolanddie9789 3 года назад

What selonoid did you use?

@slap_my_hand 5 лет назад

A couple of years ago i would have called that a big mill, but after watching a lot of videos about huge industrial CNCs, that thing looks tiny.

@bikefarmtaiwan1800 3 года назад

Very good video! Id like to let you know. however , that the music really detracted from your presentation.Still gave it a thumbs up.

@nejm1000 4 года назад

software used for CAM ?

@yoyobob1 4 года назад

So how much have you spent on this so far?

@yerimyvelez859 4 года назад

How much for a kit?

@ikbendusan 4 года назад

have you had any issues with tool pull out?

@PracticalRenaissance 4 года назад

A couple times early on, yes! But that was part of getting the tension set on the drawbar to a good amount of pressure. After that, hasn’t been an issue!

@MajorCox777 3 года назад

Thanks for the inspiration and info. I just got my version of this done. You were a huge help during the process. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-_KK081V-iLQ.html I still have to cut a length of fine thread 1 inch rod to make the spacer. But I've got this block of aluminum to use for testing until then lol
