    Limitations of using a 10 tool umbrella style tool changer

    Do you do your own programming? I've always tried to program using the least amount of cutters I could get away with. What material are you cutting? If it's aluminum you can get away with using endmills to machine holes by spiraling in with a center cutting end mill. You save using a center...

    Having Trouble with Drilling, stabbing Stainless 420

    I'd go as big as you can get away with with your pilot hole. Then take it easy on the carbide drill or whatever it is. I like two flute straight flute drills when drilling with carbide. The helical carbide drills break much easier. I'd definitely peck everything except maybe the center...

    Haas Mini Mill spindle/tool holder/tool balance issue?

    Do you get the same vibration/chatter on a straight cut? If not, the problem could be in your G code.

    I'll bet I could cut that cycle time in half.

    Suggest a facemill for Brother Speedio (BBT30)

    Yea Lott, I use them in a commercial setting. We have lots of butchers in our shop and I'm not one of them.

    Suggest a facemill for Brother Speedio (BBT30)

    OK boys, I think this is about all I can do to rest my case. You've seen it with your own eyes now so further comments from the deniers should be real interesting. The finish isn't exactly a mirror finish but it's probably good enough for the girls we go out with. Enjoy.

    That's why you wear safety glasses :)

    Suggest a facemill for Brother Speedio (BBT30)

    Yea me. I'll make a little movie file tomorrow and show you what I'm talking about. Fly cutters don't necessarily need to be too imbalanced such as the one I described above. I've also attached a crappy photo of one I made and use.

    Suggest a facemill for Brother Speedio (BBT30)

    Granted you can't argue with the math but he's talking about taking fine finishing cuts on aluminum. That means going balls to the wall. I'm not sure how fast you want to go, but if you fly-cut a 6" long bar at 10,000 RPM with a chip load of .003 per revolution, that cut takes about 20 seconds...

    No it's not a joke. Please explain why you think it would be a joke. Please be specific.

    Suggest a facemill for Brother Speedio (BBT30)

    For aluminum a rigid single flute fly cutter should work well. Use a HSS or cobalt cutter with a relatively large end radius (.03 - .05) and a relatively large relief angle. Hone the edge with a fine diamond pad and you should be good to go. Won't last for steel though. I don't particularly...

    Advice needed on buying a new or used Tormach CNC Mill

    Congrats on your purchase. You'll be totally glad you got the real thing. I'm about a year ahead of you. While working full time, I set up my Haas Mini mill one step at a time. I enjoyed it all. One thing I can tell you that kinda caught me off guard was the compressor noise. You will...

    Advice needed on buying a new or used Tormach CNC Mill

    Bob had the perfect response to your question. We've even bought boards and parts on Ebay to get our machines at work up and running. The Haas Service technicians are slow to respond with wait times well over a month and expensive once they do the repairs. So I wouldn't worry about buying an...
