Tormach microARC 4th axis machining a Christmas ornament

[@chriscourtney9099]

Nice use of probing with 4th Axis. I've been using your wireless interface with a Tormach probe for a couple of months now and I have to say it is fantastic. Combined with your modified Pathpilot postprocessor it works superbly, thanks for a great addition to the workshop. Happy Christmas. Chris

Glad to hear you're getting good use out of the wireless probe. The integration with Fusion is something I just love, it makes things so simple. A shame then that Autodesk insist on charging you to use it, especially since they can't provide a complete implementation themselves. I guess we should be thankful that Fusion 360 exists at all.

Awesome David! Hoping to get my Tormach Micro-Arc this quarter. Can't wait to try out some of your probing routines using it. Thanks for all you do for our community! Welcome to 2022!

Badass. Thanks for sharing and Merry Christmas.

man you are very professional, very nice mill and very complicate cam part, Great! Merry Christmas!

Many thanks for the kind comments. The 440 may be small, but it's much more capable than many people think.

I see the Xin Dian vise, how did you mount it to the micro arc?

Очень круто!

Thanks for sharing all the videos about the 440. I`m very new to milling, do you know if the 440 is capable enough for machining 2-2.5cm deep ti6al4v blocks? do you think the TTS spindle is beefy enough for that or a BT30 will be better?

[@daleksw]

I've never machined Ti myself, but others have done it with TTS machines. On a 440, you'd want a 6mm cutter spinning at 2krpm or less. I'd guess you'd need multiple cuts at around 10mm DoC. With larger diameter tools you'd need to drop the rpm even further and then you'll start to be limited by torque. The 440 really is at its best when it can spin at 5000 - 10000. If you have the chance to get one of the BT30 machines, go for it. They're more rigid than TTS which helps with everything and a lot easier to set up a tool changer because the taper makes the positioning a lot less critical.

@@daleksw Thanks a lot for your two cents on this David. I will try to get a BT30 instead💪
