Hi Kent; That's no problem, shoot me a message and i'll forward you some pictures of this conversion. It's a drop in replacement for the original motor assembly. In other words; bolts directly onto the standard Z axis part with the dovetail-slider in it. It's meant for an 80mm diameter spindle.
Hi Anthony. Most offtopic, but you look very, very much like an older version of a Cousin of mine, based by looking at your picture. The spindle used is the 'standard' 2.2kw chinese version. It came with a big fat .13mm runout, (the precision should be
Air is the most important ingrediënt to avoid chips from being cut over and over again. Chip evacuation is mandatory when cutting aluminium, it uses a minimal amount of lubrication (Koolmist 77) Ido like this way of lubricating a lot, relative clean too.

@@DiscoverRajivVlogs Correct, it's a combination of the tool being able to release the chip. Quality of aluminium is also a factor. A polishished surface of fine-grain carbide helps a lot. There are coatings that contain a certain amount of aluminium (oxide) that will help to melt the chips to the tool.. (last thing you want) a coating like DLC seems to be good for aluminium though, but uncoated is fine too, if you take care of your chip-evacuation and use proper quality aluminium.
No, bearings are stock. This model was using 3 bearings. Most of the current models use 4 bearings. When using a spindle like this, make sure to heat the bearings up first. Typically it's somewhere along these lines; 2 minutes of 12000 rpm, 1 minute 16000rpm, 1 minute 20000 rpm, 1 minute 24000 rpm. I'm using a macro for that. Pausing gcode can be done with G4 Pxxx (where xx represents either msec, or sec, depending on the controller, i thought most controllers interpret it as msec).
@@berendlucasvanderweide alrite, i got whit 4 bearings, what program do you use? mach3 ?, have you tried doing steel or other material harder than aluminium?. i am upgrading a 6040z 4axis chinese cnc, have not tested it yet but the main goal is to mill hardsteel and later on upgrade to 5axis.
@@carvajalm.a36 I'm using edingcnc, it's a combination of hard- and software, there is a postprocessor in Fusion360 for this controller. I did machine some stainless steel on it and some cast iron, but you don't need a high RPM for these materials. For hard steel, you need some structural strength to get a bite from the material. Carbide is pretty resistant, the machine might deflect before the tool does. I don't know what 6040 you own, but you need a relative stable machine for hard steel. Don't know what hard steel you meen, hss and up? or steel that is meant to be hardened after machining? (the latter is most common, hardening C45 for example is fair simple with readily available tools). If the machine is relative weak, I would invest time in exploring what steel is soft to machine and easy to harden.
@@berendlucasvanderweide I am researching what this spindles can mill whitout destroying it, this is the first proper video i have found wich it shows milling more than just some lines. i want to mill HSS on a future project and add a 5th axis. i understand the feed and rpm calculations, just finished my theorical cnc studies, will begin practical next week. the cnc 6040 is really stable, but need some upgrades on Z axis rods and X axis wich i will mill on school to avoid wobling. I am also familiar whit fusion360 postprocessor and cam.
Hey Berend, first of all thanks for subscribing ;) and second: on the right side of the pocket you hear why a second mister might be a good addition to your machine. I did it on our cnc a while back and its really usefull: ruclips.net/video/gJ1X-MzoN-0/видео.html ...also I used some very thick (1mm?) hypodermic needle that I bent 90 degrees on the tip to blow air and mist down into cavitis right beside the endmill. it "wraps arround" the collet like a normal fogbuster couln´t do. The end of this needles fits on the brass fogbuster rod quite well when you heat it up a bit...
You have some nice vids! and a nice machine as well! i'm awaiting delivery of a 1500x3000mm machine and was looking for ISO30 holders and found your vid about the holder. :) I normally aim the air-stream at the concave of the mill, so the endmill is 'pushing' against the air (with a CW turning tool i aim off-centre at the tool). And the +45 degree angle makes the chips fly away pretty good. No re-cutting. (or minimal). I'll look into your method. I saw your video about the 2nd nozzle. My setup came as a 2 nozzle fogbuster, with the transparant container.
wow! 1,5x3 is very nice! ours is "only" 1,25x2,5 but plent big for what we do most of the time. still - bigger is always better :) ...had jobs where I had to mill one part and then move the sheet to complete the cut. ...the vacuum table is very nice to process sheets. here is a short clip of the needle thing I was talking about. ruclips.net/video/kJPeMF9fqOM/видео.html What ISO30 spindle are you getting? HSD?
...also: I can send you the files of the ISO30 Rack I built if you like. ...but its not the most efficient or clever one I think. Dimensions are mostly based on what offcut pieces I had left from a job. ...I have to make some more holders soon and this time I think I´ll to aluminium sheetmetal instead. just bent and bolted to a board or directly on the wall.
Thanks! I'll do a search for these needles, seems like a neat solution for small mills. Indeed, an HSD spindle. Hoping it runs as smooth as yours! Tried sending you a message through YT, but it seems to be disabled for some odd reason. Machine will use 850W yaskawa servo's, it's a pretty beefy setup. Z axis worries me in terms of stability though, but that's something which should be fair easy to upgrade. Yeh, the aluminium sheets for the toolholders sound like a solid plan. Or some Dibond would be nice too. Still have some sheets of that stuf.
sorry for the late reply - was a bit sick the last days. I got the needles from a friend who is a veterinarian. dibond is a great idea. I have some dibond cutters to mill creases / folding patterns. thanks for reminding me :) our HSD is in repair right now. Had a fairly big endmill (20mm about 170mm stickout 2 flute) spinning too fast, "explode" and damage the front bearing. spindle worked fine still to finish the job but didn´t sound happy. hope we get it back soon. apparently HSD is not very quick service-wise. or they want you to buy a spare spindle for situations like that :/ edit: I added a download link to the toolrack video description. In case you want to have a look at the files.. feel free to copy the design but I would recomend to make something simpler/faster to build then I did :D

It looks like you replaced the original BF20 head with one with a high speed spindle. I'd love to see more about your design.

PM25MV just showed up. Have a Chinese spindle looking to use on it or old Taig, Would love to see some pics of your conversion.

It's cutting aluminum like butter😁😁😁😂😂. That chip removal air system is quite good, I like it.
