    Thin AL Plate Machining required USA Based Companies ONLY

    if that is one part, and not a weldment of a bunch of strips, and if you need +/-10 millionths like your decimals suggest, that part will cost you approximately one million dollars

    Stable Aluminum by supplier.

    Try making it out of plate instead of extruded bar. Extruded bar has a lot of internal stresses from cooling outside in. The other thing is to not take too much off of only one side. Take a little off one side, flip it, deck it off, flip it back etc. Also dont grip it too tight in the vise, use...

    What grease do yall use on your ballscrews?

    These double ball nuts have zerk fittings on them, I intend to just use that. It is just a M6 threaded hole, Im planning on running some 4mm tubing to it with a banjo fitting so i can grease it somewhat frequently without tearing everything apart. The Y axis ballscrew is especially buried on...

    What grease do yall use on your ballscrews?

    I seen that, but I didnt understand what the deal was with that accordion shaped tube. Does it work in a normal grease gun?

    Advice needed on buying a new or used Tormach CNC Mill

    What I did when I got started was to find a local tool rep that can get you tooling within a day or so. Then just buy the tools you need to do each job as they come. Just roll the cost into each job and it hurts less. You also then only have exactly what you need.

    Advice needed on buying a new or used Tormach CNC Mill

    I am an automation engineer as my day job. Mechanical engineering degree. I CNC converted a PM-30MV with Teknic servos, ballscrews, centroid acorn, a SMW fixture plate, etc. It cost me around $12K all in all. It has the same travels, speed, and power as the 1100MX. Actually uses bigger teknic...

    Advice needed on buying a new or used Tormach CNC Mill

    Have you seen a SMW shop tour? Saunders makes a lot of money making his fixture plates, mod vises, etc. Not a single tormach is used by even him in production. His Tormachs are all exclusively for his classes. Abom79 just did a shop tour of SMW / NYC CNC, go watch it

    A dodgy slitting job.

    I dont have much experience with slitters, but i have much better luck with shallower step-overs and more passes. like a 20 thou step-over (0.5mm) Also I usually run them conventional instead of climb milling. Think more like a table saw or chop saw. Could be totally wrong here, but it works...

    How bad is it to use TiALN coating on aluminum parts?

    Update: I let'er buck because i had to get the parts done. After ~10 hr of running the flutes just developed an aluminum looking coating. Cant tell if just stuck on or what, didn't try very hard at all to get it off. Didn't seem to affect dimensions on the parts. I was just using WD-40 mist and...

    How bad is it to use TiALN coating on aluminum parts?

    Ive got some TiALN coated carbide ball endmills I would like to use for some 6061 parts for a rush job. Rush as in they want them tomorrow so it will run all night. I understand TiALN created an aluminum oxide coating when used, and is not recommended for machining aluminum. How bad is it for...

    I have a question about facemills

    if you go with a 4 blade, and your machine cant handle 4, then you can take two inserts out. Then you can run it like a 2 blade cutter and still be balanced. 4 blade lets you go 33% faster than 3 blade with the same feed per tooth. But it needs 33% more power. I would go with 4 blade

    Haas Auger causes surface finish issues, anyone else?
