Custom Milling
 

A good friend of mine owns a machine shop and over the years I have picked up on a few things.
It took a while but I learned to run his CNC mill and together we made lots of coll stuff.

He told me that for the price of a nice truck, I could get my own CNC mill and along with all
the work I needed done I got one.

This thing is so strong and fast all the parts I needed made are done, I also did some paying jobs.

I had so much fun programing and running parts I am looking for more work.

So. If you want something like a new bulk head for turbine plane, I can build it.

The problem with all this is.... getting what you want into a drawing.
If you have autocad or Solidworks,drawing allready, Its a 1 hour job to make a part.

If you can make the part from wood, and send it to me, its a 2 hour job.

Also... I can do 3D parts IF you have a 3D drawing file. I can do intakes molds from
just a few drawings.

Prices will be Around $100 for simple stuff like flex plates... $100 for the first on.. ~$20 for extras

This is for a few months only, because any longer it will be a job.

That's a nice machine Eddie. very, very cool.

RE: Custom Milling
 

Wow!

That milled dog next to the plug parts looks so realistic!!!
;)

What material are you using for the plugs? MDF? Thats what we use in our small hobby mill.

Will keep your offer in mind.

RE: Custom Milling
 

how long it tooks you to machine the last parts?
my cnc has a positionning speed of 4.2m/min and cutting of 1.5m/min but to get such result, it would take years anyway...

RE: Custom Milling
 

That was not done on my machine... It was done on one very simular, just larger.

That plug was roughed out with a 2 inch (50.8mm) cutter running 0.400" (10.16mm) depth of cut at 100 inch/min (2.45 m/min).
Then it was finished with a 1" ball endmill where the highest ridge was around 0.005" (0.127mm) witch sanded right out.

Each board of MDF wsa 9 layer thick and took about 2-4 hours. where the max length of the boards were 38".
There were about 8 boards total.

Lots of pic and a movie here

So.. If you have a 3D drawing and need a plug made, I think I can do it.

RE: Custom Milling
 

really nice machine you have!


sure you can do nice job!

RE: Custom Milling
 

How much to make a plug?

nothing too big, say 68-72in. long?

RE: Custom Milling
 

Yeah, MDF sure is nice!


Here's some pic's of my work...

1) The machine.
2) Milling.
3) The resulting mold.

RE: Custom Milling
 

Making a small 68" plug from a nice 3D drawing can be done for $4000 to $7000.

If I have to make the 3D drawing from scans or .dwg or .dfx files the price could double.

RE: Custom Milling
 

And from another project:

Here the layers of MDF were cut individualy and then put together. This allowed us to mill boh sides with great accuracy.

RE: Custom Milling
 

Look what i did with mine a couples of days ago.

They are the same size as the robart 630 series, but stronger. Made with 1/8 thickness instead of 3/16 and will have a trunion made with 7000 serie aluminium instead of 6000.

I want to hit the market after Xmas. 125$ to 150$ for a set of 3. It's the first proto, the finish is not good but they will be anodized anyway.

Programmed directly in G codes. I'm using CatiaV5 for more complex design. Done on a Republic Lagun 4 axis mill.

RE: Custom Milling
 

pas mal le resultat...

pour mon f22 je suis en train de voir si je vais pas me faire un ptit retract custom pour une rentree des trains principaux plus scale...

envoies ton email par pm que je puisse le garder au chaud pour quand j en aurai besoin.

si j envoie des pieces sous catia V5 tu peux les usiner pour un prix correct?

ma cnc 3 axes est pas mal pour la decoupe des profiles mais pour des profiles comme ca, il manque un axe!

RE: Custom Milling
 

I spend all weekend trying to make 350 of these parts... They are 1/8" by 1/8" with a notch cut in them.. +- 0.002

Man.. I want round and round... .. can make 25 of them at once... but time after time 25 were not
within tolerance... I must have made a few hudrend before I found out that the 1.5" aluminum plate
that my vise was bolted to was somehow moving durring the cutting. ????

I removed the jig plate.... bolted the vise directly to the table and that fixed everything.
Now I can hold +- 0.0005" and I still dont know what I am doing.. hhaah

RE: Custom Milling
 

Hehe!

At that size, very little vibration can do some damage! ;)

I'm testing home anodization by now..Not quiet a success....

RE: Custom Milling
 

Here is my 2th try in home anodization. This time it works!! I only did 1/2 pf the part but the color was ok. Now i'm working on finishig process. The better the surface look the better the anodization look ;)

RE: Custom Milling
 

Lookin' good!!! What did you do to get your anodizing success???---Turn up the current??? Are you making complete retracts w/cylinders or are you just making replacement side frames and trunions? Did you get my PM on your retracts? Keep us posted!!!

RE: Custom Milling
 

Look what I did some months ago with my MCBH milling machine for a BobCat of a friend of mine.

Aluminium 7075 T-6 150HB

Air cylinders underwater tested a 110 p.s.i. ANY BUBLES ;)

RE: Custom Milling
 

Just got some new software and I am now able to do 3D mold or plug work.. no problem..

Just as a test I made a mini Megabar..

If anyone needs a plug or small Aluminum mold,
my price for any work is now much lower now..

RE: Custom Milling
 

Hello Eddie,

Looking good!

When Microbar is available??

BR,
Jussi

RE: Custom Milling
 

Which software are u using?

RE: Custom Milling
 

I use Solidworks and SolidCam. The new Solidworks 2006 Solidworks can do some crazy things..

RE: Custom Milling
 

i use SWorks 2005 and indeed it's a great program. what the heck is that a picture of? Some railway assembly??

RE: Custom Milling
 

My machine has been off for a few days.. No work.. Anyone need something done... (Last time I ask)

btw... 3D work even without 3D drawings is much easier now and cheaper

Here are some jobs I got here on RCU. Thanks.

Eddie,

Is that a turbine balancer I see in your first picture?
