    A coax is by far the easiest tool to use for this job, but it must be held very concentrically in the spindle because it doesn't self correct for runout the way a test indicator does. That's the...

    Probably both.

    Step 1: learn machining

    Step 2: learn lights out machining

    Step 3: go golfing while machine runs lights out

    332225

    Look at the skinny triangle first. 19mm and 73.5mm dimensions are known.

    (1) Solve for the hypotenuse: C^2 = 19^2 + 73.5^2

    Google: sqrt(19^2+73.5^2) = 75.916

    (2) Solve for the...

    We have two Chicago QRS compressors. They're reliable but on the noisy side. Our QRS15 is made in Italy.

    Kaesers are top of the line but aren't without their own faults. Our SK15 has a foam...

    Aluminum machining from the sounds of it, and carbon fiber trimming.

    You'll need a hollow subspindle drawtube (nonstandard, but available), and ideally a rear discharge conveyor to clear the right side.

    You'll also need to find a way to eject the part. LNS makes...

    Many variables. Topping the list is supply chain reliability, i.e. the extruder. A bad supplier can erase all your gains.

    Is this 6061?

    Quantity and frequency of customer POs on this part?

    By his logic, an inch machine can't cut inch threads either.

    Inch threads = fractional pitches, and any fraction with a prime denominator has infinite decimal places and thus can't be...

    One way is to have them do it. Have them measure a handful of parts using calipers, mikes, and gage pins and see how they do.

    The value of such a test is debatable. Possibly more important if you...

    You won't need tool life management for 6061. Replace tooling on a scheduled basis rather than on a timer. Use PCD where applicable. Err on the side of caution and run your coolant rich, but not too...

    There's no easily solution, so you'll have to get creative.

    Consider filling gaps, counterbores, etc in your fixture with silicone RTV wherever possible. The stuff is a pain to remove, so keep...

    The ability to plunge endmills has gotten better over the years, but it's still an inherently unstable process where the only failure mode is flute packing and instant breakage. No warnings through...

    How big's your machine?

    Our 22" vise with machinable soft jaws and Mitee Bite Versagrips will make quick work of that. One vise with wide jaws or two vises with normal jaws.

    Consider a 275 or 330 gallon IBC tote instead. Even a small drinking water RO system will fill that up in a single weekend.

    55 gallons is barely big enough for top-off when you have four machines,...

    I'd plan on pouring dedicated foundations for both those machines. Small price to pay to ensure highest level of volumetric accuracy.

    If you're on board with that, take that into consideration...

    Maybe the pace of the course is too slow. How much time are they spending coding basic 2D shapes into G1/G2/G3 toolpaths?

    In the real world, it's not about being able to write toolpaths by hand....

    No, but Desktop Metal and Markforged's Metal X both use technology similar to MIM.

    So users of those systems would probably run into the same issues as the OP.

    A cordless drill will do the job but it's not fool proof. Clutches can get bumped and aren't that accurate to begin with. Torque also doesn't stay consistent as the battery drains.

    It could hypothetically trigger the probe but I've never seen it happen. We use air blast on most probing cycles.

    Nice looking clamps!

    We chose anodized aluminum for the supplied clamps in order to bias wear towards the clamps rather than the T-slot table.

    Our Kaeser dryer died after 3-1/2 years of service. Kaeser's techs said it would cost more to repair it than buy a new one.

    We now have three of those Schulz units. They're made in Italy,...
