There is another green-metal that does not require Argon.

 

[REJ]

That could be interesting. Who makes it/what is it.

Hey REJ wanna trade my two Origin Machines for your 450i lol. Man I can't wait to get my hands on one. Have to wait until next year though. Maybe I'll take a trip to the Midwinter to take a peek at them.

 

[REJ]

Hey Tyler just stop on by we would welcome you to come on up and see what they can do.

About 10%

I wonder if anyone has thought about costs of milling "soft" vs. "hard" CoCr (I am thinking also of investment costs in larger vs. smaller milling units)

You could plan on an extended trip at midwinter, our lab is only 2.5 hours from Chicago if you left on tuesday or wednesday after you'd have a chance to come down and work with the 450i for real, not just a demo.

I had that discussion with Mr Stark and he and I felt it is similar to the open vs closed milling debate. If one saves a bit on hardware but loses on consumable cost it never makes sense. IMHO the reason I spend on hardware is to lower recurring costs and amortize out the cost on it for tax which I can't on high material costs. Assuming that green state material costs more than full chrome cobalt, why not invest the money in the mill rather than the special over or oven capacity. Also I always look at it as a cost per unit equation as we do really significant volumes of work with the machine cost factored in, with tools etc. I am really surprised by the tool life on the cocr in the 450i. It is as many units as our wieland mini gets for zirconia but the tools are less for the big 6mm shank than the little 3mm guys, something is off.

How many units are you milling with one set of tools ? How many tools you are using and what diameters are they ? What about speed ? Sorry for the amount of questions , but I am also milling CrCo and want to compare with mine . Thanks .

 

[REJ]

we have ours currently set for 80 units for roughing and second cut and more for detail. Currently using a 3, 2, 1, diameter. I didn't set speed, but think I saw it at 21k for 3mm, dry not with water or oil.

 

[Drizzt]

So you are getting 80 units dry milling? Nice number . I use 2 mm roughing, and get half of them , wet milling , but thinking of switching to a 3,2,1 strategy . You have 6 mm shaft right ? When I mentioned time I ment minutes per unit . I have an average of 20-21 minutes per unit . I am so curious about 450i because it was a machine I was considering when I was shopping .

If I end up going to the Midwinter show I will definitely leave a little earlier so I have enough time to see them in action. The 450i has me really intrigued and I can't wait until next year to hopefully be able to get my hands on one.

I have never seen 6mm shank diameter tools cheaper than 3mm.

It is much more machining to cut down a 6mm shank to cutter size.

You should shop around I think Ryan.

First milled emax on the little guy.

 

[NicelyMKV]

Ryan, are you accepting files for Emax CAD now? I would like to send you one of my designs to check it out off of the 240 if possible?

You guys are fricken hilarious, I'ts like milling porn!!popcorn

 

[REJ]

Could go full cast too Jason.

 

[REJ]

We could for you, I just will be out for DLOAC Thursday to Tuesday but Jim is back friday and can do it too. So if you send it tomorrow we are good.

Hey Ryan how long does the clean up take when milling wet to dry?

 

[REJ]

Dry to wet, about five, vacuum out the chips, attach the wet holder. Wet to dry take out the block holder, six screws wipe up the coolant which stays right below the bin so about 2 minutes, it always drains itself so not a lot of coolant to clean. and a magnetic shroud that we use one for dry one for wet that is covering the air puffer/coolant sprayers. That keeps the water in check. We have a ten tool holder so we have tools for both in all the time. I'll take a video of the one I mill for jason the chrome was dry milled so no change needed.
