Another very nice vid of that fantastic machine in action!
I really, really love that enclosure and the amazing torrent of coolant you've got running through it!
Very impressive.
Both the machining and the amount of coolant!
What was your DOC etc?

Hi,
Depth of cut in that smaller cavity roughing was 9mm, widht of cut
was just 1mm, feed was around 1050 mm/ min.
In bigger cavity, roughing operation depth of cut was 4.25mm, widht
of cut was 2mm. Feed rate 3000mm/ min, 5300 RPM.
Tool life seems to be much longer when there's plenty of coolant.
HSS roughing cutter from Guhring has been very good for
for these kind of aluminium jobs. I like to make these kind of fast aluminium runs. Would be nice to own something like Robodrill, Brother or Haas super minimill and really do some fast machining!
Or should I design and build bigger DIY mill with something like
4kW spindle motor? Some really badass machine with 300*300*10 mm steel column, Tormach BT30 spindle, 8000 RPM?
Very impressive!

I'd love to see the build log if you do, but surely there are better designs than the basic canterlevered head on a column mill if you're going that large?

Traditional C- frame design which these small mills and vertical machining centers have, is pretty easy and simple to build accurately. Just few big parts to make and adjust to get accurate machine. Maybe something like gantry frame is too complex for DIY builder?
I'm mainly just thinking about different alternatives now. I would be interested to buy some bigger industrial level machine at the future when I have spare enough money, but the problem is that then also bigger 1st floor work shop is needed. Even small production workshop places have pretty very high rent where I live. My current hobby work shop is at the third floor, and freight elevator size and 1600kg weight restriction limit what I can bring here.
Chinese seem to make machines like there's no tomorrow:

That Syil X7 frame looks good. If they add automatic tool changer to that in the future I will buy it!
But steppers needs to go, if it has steppers I have to put servos instead.
There's also interesting machine:

that second link is the same machine as the syil x7. im curious what pricing would be. the regular syil is $10k, so id imagine the tool change, spindle, servo, contral and housing upgrades add at least $10-$15kk more. gets out of hobby land i think, but probably still alot less than a hass with similar features. if the quality was there, it might be a viable option.
opti also has this thing for about $25k.:

Yeah, those starts to be so big amount of
money that you rather like to think something
like Haas tool room mill or minimill.
There's interesting Fryer tool room mill, ATC is
optional:
[url]http://www.fryermachine.com/toolroom/mb_r_series1.html[/url]
Price $32,980.00, I don't know if ATC is included in that price or how much extra it does cost.
Seems to be much more rigid than haas tm1. Costs about same.
Where do you have seen that Opti F 100 for
$25k?
I have only seen prices like 44-52kEUR, that is around
$76k ...
[url]http://www.optimum-maschinen.de/produkte/fraesmaschinen-cnc/f100tc-cnc/index.html[/url]
I think it would be possible to put that into freight elevator if some sheet metal etc. is removed, but if the real price is 52 keur, then I think it is overpriced machine. With 52keur you can get something like Mori Seiki Dura vertical, Haas VF3 of Fadal 3016 FX. Hmm...If I would have extra 52 kEUR, do I buy Mori Seiki VMC or Opti F 100...

huh. i could have sworn i saw and ad saying 25k. maybe it was for something esle.
for $40,000 you can get a haas tapping centre, so id bypass the opti altogether.
I guess your weight limit is going to be the biggest problem if you are looking to buy a 'real' VMC. There are some amazing bargins in 2nd hand machines on professional machine-tool auction sites at the moment - I just wish I had the space and the 3-phase power for one!

one thing i regret now that have the funds and space is not snatching up a new complete "rolling chassis" vmc for $5000. was a compact travelling column machine with 30x16" travel and basically just needed motors and electrical and control.
ah well :)

Yes, freight elevator weight limit is the biggest problem.
Haas minimill might be possible to get into this small workshop. Have to ask few questions from minimill owners or from reseller in the future.
Here is a new machining video from the weekend:
"http://www.youtube.com/watch?v=RyFK235W-h0"]YouTube- IOM_RudderMould.wmv
Some hard rock background music of course :)
JMI80
I love your machine, particularly the fact that you use EMC2 :)
Couple new videos:
[nomedia="http://www.youtube.com/watch?v=PgpWrl35I4Y"]YouTube- EyeboltMachining.wmv[/nomedia]
[nomedia="http://www.youtube.com/watch?v=LytH7eCuvDk"]YouTube- MastPartner.wmv[/nomedia]
What do you guys think:
Should there be background music at the machining video or not?
Is heavy metal/ hard rock the only right music scheme for machining, or is techno/ techno rock a good choice?
I really would much rather listen to the beautiful sounds of the cutter tearing through the workpiece and hear just how the motor is handling the load. Both techno and heavy metal (esp. death metal) more lend themselves to backround music, to enjoy while I'm violating motor vehicle laws at excessive rates of speed.
Seriously, it is always a pleasure to see your machine in action, if I ever get around to converting my BF20 I think I will just swap the head out altogether also. Great job!!

This time no backround music during machining operations!

I think that death metal is very good backround music during evening shift
when big horizontal machining center's and big VMC's cut metal like there's
no tomorrow!
Drive safely :nono: :)
I always enjoy watching your machine and your videos. Very cool work and you are obviuosly a master of that machine.
Couple of questions,
Were the thumbwheels also Stainless?
Also, what is the clicking noises in the video?
That is an impressive machine! Nice work.

Hi,
Thumbwheels are just from aluminium. I don't do much stainless or steel machining with this machine. Lack of spindle horse power soon comes obvious if there would be much material to rough away. Aluminium, brass, plastic and wood goes just fine with this machine and can be milled with pretty good feedrates.
I also like to do aluminium machining because pretty cheap HSS cutters work
just fine and they last forever in aluminium machining. During the years I have spend something like 2000-3000 euros (around 2700-4000 USD) to solid carbide cutters to be able do steel machining effectively...This is pretty expensive hobby...
Clicking noises are from camera autofocus... It's Pentax optio W60 camera.
It's a waterproof camera made for tough use. Pretty nice camera to use for these kind videos, but those clicking sounds are definitely bit supid. I could
try someday if it's possible to shoot sharp videos without autofocus.
