Carvera Air Titanium Milling Test

Here's a demonstration of a Titanium milling test using the Carvera Air, employing appropriate milling bits and a relatively slow feed speed (you can see the settings in the video). This approach proves that you can indeed produce small high-quality mechanical parts from such tough materials. Additionally, we've conducted tests on carbon steel and stainless steel, finding they also work with similar parameters, will share them in the near future.
The Carvera will be launched on Kickstarter today.
Don't miss out on the excitement:

Interested in mild steel and stainless steel performance.

[@ZennySilverhand]

Super cool. What grade of titanium is this ? Can hard materials like these be cut reliably over time?

[@Makera]

grade 5, but we don't recommend full-time processing of hard metals like titanium.

[@YsgdSojdd]

Absolutely impressive that it can handle carbon steel. This CNC machine is truly captivating.

[@arkhauss11111111111]

wow :)
cant wait

[@Asnovich]

Ofcourse small steps and low feed is okay for Air vs titanium. But it does great job , very rigid. Thank you!

[@fatassbattlecat]

Dont think you could work with such a long end mill if there was significant force on it. Therefore, this test does not demonstrate rigidity

[@Asnovich]

@@fatassbattlecat yes, they definitely should try endmills length to maximum shortness and probably then they can do deeper step or faster feed. I thought they did this because that was maximu for z axis. If that's problem. Then they just need high claws.

[@CrudelyMade]

does that mean the original carvera can do this too? or was something changed where this machine is more rigid?

[@Makera]

Sure, the capabilities are very similar, Carvera just have more features.

[@CrudelyMade]

@@Makera good to know, will be waiting for the settings for steel,etc. what bit did you use for the titanium?

[@DoRC]

Very nice! Obviously you have to go pretty slowly but being able to cut hard metals at this price point is amazing. Can't wait to get mine

[@Energetic_Ballistic_Solutions]

I understand the 4th axis is not rated to cut heavy metals, but it would be cool to see.

[@clausziegler5720]

But can it be used with cutting Aluminium???

[@GDFindexieYT]

@@clausziegler5720 yes it can, they posted a video showing

[@Energetic_Ballistic_Solutions]

@@clausziegler5720 yes

[@Makera]

Yes, 4th axis works well on cutting aluminium or copper.

[@ironedge0]

What is the 4th axis' limitation? Why can't heavier metals be cut on it? And is upgrading it a planned idea? I'd love to cut titanium rings on my carvera air

[@Gazza_Roo_Too]

what sort of wear rate is titanium on bits ?

[@Makera]

Compared to aluminum, quite high, especially when using single flute bits. But with proper bits and slower feeds and speeds, as well as use of ramping and chip evacuation through air-assist, wear is acceptable and manageable as with most materials.

[@TheVFXAssault]

Next time i highly recommend, keep the tool stickout much lower than this. The results would be even beter.

[@Makera]

Thanks for the tip!

[@skatedoc9567]

Any chance of a 5-axis expansion?

[@ReactiveWork]

There is a 4th axis module available as an add-on in the Kickstarter.
5-axis machine would typically be in a very different form factor.

[@destaaf11]

Impressive! Is the air cooling included in the machine?

[@Makera]

Not included, but you have a port at the back to plug in a external air assist.

[@CraigTrader]

The internal air cooling port IS included, but the external pump to provide pressurized air is NOT included. (That's the same as the original Carvera.)

[@alexeyshalin8496]

Try increase DOC and feed

[@23lkjdfjsdlfj]

WD-40 isn't a lubricant. I don't understand why you would use WD-40. Any suggestions for an actual lubricant? Or, is the person in the video not really lubricating? I'm new at CNC.

[@DoRC]

WD-40 actually is a lubricant. It's not a very good lubricant for a lot of applications but it probably works pretty well here.

[@dimsum5567]

Swipe across the table with the dial indicator, I am sure potential buyers would like to see the geometry of the machine, with the die cast frame and no adjustments whatsoever it’s a biggest concern.

[@creepinonthebabes]

will be nice when they start making these enclosed units that use coolant like maybe hold 2 gallons of coolant. designed for metal not geared toward wood engraving. maybe look into a KOOL MIST for coolant on that.
