I mean that chinese aluminium is 15$ cheaper per kg than aluminium imported to china. I asked from one chinese cnc manufacturer about their aluminium quality and he didn't know the difference between...

Hardness is one I guess? Cheap Chinese Aluminium is little softer?

Same question for steels too.

I got more information about the full lenght thread:

I was told that first they would make 17mm long thread with standard tool and the remaining 3mm would be made with special threading tool that would need to be machined for this purpose. So it is...

I didn't find any charts, but one site says that 1/2-13 internal thread major diameter is 0.500 inches. So it's same as the listed diameter of 1/2-13 screw. The screws are always a little bit smaller...

Yeah I wasn't familiar what that english term meant, but now I understand. Thanks.

One more question about threads. How do I know what the internal diameter of female thread is? I mean the total...

Thanks for the reply. 4mm is too much in this case. 1-2mm is doable. I'm not familiar with the undercuts. The problems is not as important in male thread, but more important in female thread. Could...

I have 20mm deep hole that I need to tap with 1/2-13 thread. Will the thread go to the bottom of the hole or will there be short part that will be unthreaded at the end? I'm ordering these pieces...

Machnists wants to know what anodizing method I want. I'm after bead blasted matte black and grey finish. What are the options and what should I choose?

How about laser printing? What is plusses and minuses with laser and silk printing for aluminium (if only white print color is needed)?

0.010" would work on outside diameter (at least I think so), but the surface needs to look good after bead blasting and anodizing. So if bead blasting and anodizing won't hide those big scratches,...

Yes I was thinking to build something made for that purpose since it's the only shape I need.

I need to use aluminium that anodize well. What would you suggest?

I mean that the person who operates the machine knows the process well. For beginners I would guess one or two with * up tolerances :p

Yes I know the setup takes the most time and once you have...

If my parts are under 100x100x5mm rectangles that have few holes/threads each side and some other easy shapes. How many parts is realistic to manufacture with BF20 in a (8 hour) day? I have no...

Here's better image of the surface I'm after (the grey part, mine will be black): http://homepage.mac.com/xeonitedog/Kimber04.JPG

I've been reading mixed opinions about the bead blasting. Some people say sand blasting for aluminium is bad if you anodize it and that glass blasting is better. The nsome people say that glass...

Here's another pic that shows the black matte look I'm after: http://www.rankinarms.com/guns/files/unique-002.jpg

Ok. Does the silk printing wear off in rain for example (just trying to figure out how easy it comes off, I guess it lasts better than spray paint at least :p)?

I looked up some images from google...

I need to bend rectangle aluminium bar around 5x40mm like this:

http://ecx.images-amazon.com/images/I/41%2Bfm5yIdUL._SL500_AA300_.jpg

to have 45 degree turns like this:
...

I would need something that doesn't wear off the second it's moved against another aluminium plate. It will not give very professional impression if the text goes off too easily. So maybe silk screen...

Thanks for the reply!

Does the silk screened print wear off easily?

I'm looking to get this kind of finish, so I guess bead blasting before anoziding is the way to go:
...

My new price limit is 4000€ (machine and CNC conversion with ballscrews). Any suggestions besides X5 CNC and BF 20L?

X5 CNC:

X = 400mm
Y = 160mm
Z = 380mm
1KW
70Kg
Table = 500mm x 160mm

I see lot of aluminium products being anozided black and then there's some text like brand or product name on white text. How do you archieve that? First anozide black and then print the text/other...

Ok, after that I contaced them and said the X3 would be too pricey for me and I was looking to get either X2 or X5, since even X2 works well with aluminium (as you can see on these forums), at least...

Is there any X5 (BF20) users here? What do you think about the machine?

Link: http://www.syil.co.uk/product_x5.htm

I sent email to Syil about the X5. I got an email back from a Finnish company (Syil dealer I guess) that they have been told that I'm interested in CNC milling machines. They asked what model I was...

Ok, thanks for the info! Is it possible to install hand wheels for X2 CNC?

What are the difference between these two conversion kits (the one installed in X5 and the BF20)? Does the original BF20 conversion kit perform better, is it more accurate or do they both do the job...

Options as for now:

X2 CNC = 2600€ (ballscrews, but no hand wheels)
X5 CNC = 3000€ (ballscrews + hand wheels)
SPG 2217-20v 900€ + Optimum CNC kit 2000€ = 2900€ (hand wheels. but NO ballscrews)...

Ok. The X5 seems to be BF16 CNC'd.
