I don't get why some people say Tormach is underpowered or less rigid like it's the end of the world. It runs on a dryer circuit and does stuff WAY cooler than drying clothes. I mean, a DMG DMC1850V is probably gonna need 480 3-phase. Good luck hooking that up on a residential account. A budget CNC coupled with a creative designer can really make effective use of the tool.
Very nice video. For low HP machines like the Tormach and typical entry level home shop and small shop machines, it's hard to beat the Tormach SuperFly for facing operations. Using only one insert ensures that there can be no insert misalignment so the surface finish is gorgeous, and if the tool is crashed, there is only one insert to replace (haven't crashed the SuperFly yet). I still need to get a second SuperFly, just because I'm so lazy that I don't want to change inserts when switching from aluminum to steel. Yeah, that's pretty lazy. The SuperFly is one tool that requires a good tramming of the spindle to avoid cutting a dished surface. It'll look smooth and it'll be smooth, but it won't be completely flat unless the mill is properly trammed.
Can you do one showing the math of all the Face mill cutting techniques? Or even the method of how to calculate the feed rate of a face mill and the how to find the chip load per tooth?
I'm doing a face milling job on 6" wide x 1" thick HR flat bar. Using a 2"shell style cutter, the issue I'm having is steps, .005-.006 deeper or shallower with every pass. I'm only taking a small bite, .010 -.015 dept. What could be my problem? Thanks
Since there could be all sorts of variables, you could ask that question on the Tormach Forums forums.tormach.com or possibly by opening a Support Ticket with one of our Tormach Tech Support staff tormach.com/how-to-submit-a-support-ticket
Is it safe to use a large face mill on a small piece of stock without running the risk of it flying out of the vise? For example if you had a rectangular piece of aluminum stock that is 1/2 inch x 1/2 inch by 2 inch with the square side sitting on parallels and 0.02 inch clamped in the vise and you did a 0.50 inch face mill pass with a 3 inch face mill, could you expect that to cut just fine or would the stock likely just fly out of the vise?
The scenario you described would not cause any problems as long as the material is properly clamped in the vice. The important aspect to any machining operations is the part being securely mounted to the machine.
Burs come from the material more than the inserts themselves. A little trick I use to minimize these is to climb cut into the edge of the material. This will create a clean edge. If you are only taking a single pass this doesn't work but if you need to take multiple passes you can program it to come from both directions and minimize your burr.
Hello Ramazan, yes we used an MQL system for this video. Our machines are compatible with the Fogbuster systems they are available on our website here: tormach.com/catalogsearch/result/?q=fogbuster
Not sure what level of excellence you expect for the price. They have a niche - hobby, education, prototyping, and limited production. If you can point me to something better/cheaper, I'm all ears. But I suspect you can't, or at least by a significant margin.
I still love the look of trochoidal marks no matter what people say

Thanks for these great comments! Tormach's goal is to make CNC machining accessible to everyone. Single phase machines accomplish that.

not lazy, replacing insert take time, which could be use running the machine

thank you very much for the knowledge sharing!

@@tormachinc Makes sense! Thank you!
What would you recommend face milling a pocket in cast acrylic?
What's your recommendation for depth of cut and feed for facemill BDMT on stainless steel 316?
Is it possible to face milling a cylindrical work piece?
I have a bohlerit shell mill but it sadly still leaves burs is this the varying height thing?
I suspect the fly cutter is the better option?
Burs come from the material more than the inserts themselves. A little trick I use to minimize these is to climb cut into the edge of the material. This will create a clean edge. If you are only taking a single pass this doesn't work but if you need to take multiple passes you can program it to come from both directions and minimize your burr.
Excellent explanation
this was so helpful thank you
very informative thank you!
this beard is a hazard on the mill
We highly recommend the use of beard guards for anyone with longer beards.
Is it MQL that used in this video as a coolant?

Kinda sad to hear how under-powered Tormach machines really is.

OK, thank you
That's... Not a shell mill. That's a 90 degree face mill. A shell mill doesn't have a 90 degree cut
