All the are to know about milling! - Page 2

mwolfman · 09-23-2004, 03:22 PM

Ok, I get the point.
So do anyone of you guys have a small (at least 3 axes) CNC-mill for about 300-350$ ink shipping to Sweden?
That is working and is close to plug and play?
The speed is irrelevant, as long as it dose is job!

mwolfman · 09-27-2004, 01:42 PM

That’s I’m going CNC in this week, making CPU-blocks (3) and 3 GPU blocks...

6500 rpm (that’s the machine speed)
25 mm/min
2 mm bit
Doing 0, 8333 mm/down
And high presure coolning...

Are these figures OK, or is there anything that I should change?

JFettig · 09-27-2004, 07:56 PM

It depends on how ridgid the machine is, but at that spindle speed, I would be you can more than quadrouple the feed rate. with a 1/16" EM and half that spindle speed I typically run 2-3ipm

make sure to plunge slowly, like 25mm/min if Im correct, thats like 1ipm, so Im sureyou can do 4ipm cross feed.

oh, it also depends on if its carbide or hss, these numbers are for carbide. If its a really big machine, it can probably double that even and go around 8 or so inches per minute.

This machine is BIG and almost NEW (done about 20 h in total!), and the precission is 0.001mm and 0.002 degres, the problem is that I dont know the quality on the rodd, I think is a HSS :-(

The cutting edges on carbide will be less acute, if meant for the same duty as the HSS. Just a clue.

JFettig · 09-28-2004, 07:01 AM

Kobuchi, what do you mean?

mwolfman: are you saying this thing has rotary axises? Who is it thats running the machine? they will probably know better what it can handle.

Has 4 axes (xyz and can rotate the board (the place where you mount the block))
but it can also move the tool by (down to) .002 degrees steps..
I told you that is big... (can handel 40 tools)

The problem with the machine is that they dont know what they are doing!
(Thats why the lett me play with it)

JFettig · 09-28-2004, 07:49 AM

whoa, that sounds like a really sweet machine, whats the make?

Who is it that owns it? you should get msn messenger and Ill help you out a little bit on the setup and all if you need. wow thats some crazy stuff.

I mean if you compare a HSS tool to its carbide brother, you'll note the angles of the former's cutting edges are sharper. Carbide is more brittle so cannot be ground/sharpened at such an aggressive angle or it will shatter in use. I doubt mwolfman needs this info for regrinding a bit, but it is one clue to visually distinguishing carbide vs. HSS.

Its own by LTH (Lund Institute of Technology), they should use more than they do but the ones who did know how it works has jobs elsewhere.

My BIG BIG problem is that when I handed the ProE files to the guy who’s job it is to make the mill work, didn’t know how to make it to suitable G-code. And he refused to make it as I designed it due to the complexity.

I have the part in Solid works and ProE (exported from Solid works).
Anyone how knows what to do with it? (I’ll only need 3 axes).

JFettig · 09-28-2004, 08:03 PM

I think he would appreciate an autocad drawing

is it basic 2d and depth work? by this I mean no 3d contours, wich most blocks are(2d) it shouldnt be too difficult with an autocad drawing or even a very good pencil and paper drawing. It also depends on what software he uses or if he programs it by hand.

Its 2D with depth work (I have a block that’s 3D but that have to wait until I get a 5-axis mill).
He has the same software as me, and ProE can make CNC code, but I haven’t done that course ...

yet...

mwolfman · 09-29-2004, 05:37 AM

He is making a derlin block as I'm typing!

And he is making it in this machine (minus 1 magasin, only 40 tools

)

I'm geting my Nikon Coolpix 5200 any day now... then I'll upload loads of picts!

mwolfman · 09-29-2004, 07:28 AM

The prototype had the CPU-center misplaced 2mm in x...

Making a new model (have to write the code by hand!

)

I’ll upload a picture off the prototype when I get the camera.

davidzo · 09-29-2004, 08:00 AM

wow, thats an incredible machine, really nice. Must be real fun to make coolers with this machine

looking forward to see a picture of the prototype, get yourself a cam

mwolfman · 10-03-2004, 02:52 AM

Have a bit of a backlash; the mill is going to be used this week! (first time ever in 5 years or so)

In the meantime I’m getting a CNC-software (CAM) to get the VR-models to G-code and hopefully I’m back on track after next week. (any software suggestions?)

My camera is on its way, if the postal service only could work on weekends (I know were its 30 km from me, and has been there for 3 days!)

PS the accuracy on the mill is better than 0.001mm and I’m only using 10% of the power @5000rpm!!! DS

mwolfman · 10-06-2004, 03:57 AM

"This is the prototype; the orange is just to mark where it milled, and the mill…"
but the images where to large, dont have time to reduce them.

here they are and the mill...

mwolfman · 10-28-2004, 07:33 AM

OK, finally the G-code is away!
Hade some exams that took loads of time...

My plans were that I should have the blocks ready before the weekend and install the kit in the new chassi... My mother wants me to help her before the winter comes :-(

mwolfman · 11-11-2004, 01:59 AM

Ok, the prototype in delrin is done.

If the prototype is ok this time the guy how handles the machine has my clearing to make 3 blocks in copper.

I might release the code on the forum, haven’t decided yet.

Jag · 04-22-2005, 04:39 PM

Just saw a thread in xtremesystrems forum, of a delrin Whitewater top made by JFettig, and that's a good machining.
Here's the LINK

C'mon...let's see that G-code. I'm eager to run the simulation...

Moto7451 · 04-24-2005, 10:53 PM

I use a Flex Shaft drill.
Motor: 110-130VAC .5A Brushed motor
RPM: Variable; up to 14,000 RPM
Built in the early 1970s. Still kicking it to this day. Awesome tool. It works better than any Dremel I've used. Its normally used in making jewelry.

Susquehannock · 04-25-2005, 12:58 AM

Anyone here still use a Bridgeport mill?

Hi
Im doing a paper on my watercooling system during this sommer, I might release the code after that (if it's to expencive to manufacture on a large scale)...
