    Mcam Solidwork vs draftsight

    Select all Transform/Scale At the bottom of the window that pops up you will see 2 rulers and a calculator. Select the ruler on the right to scale it from metric to inches. This will make it smaller by a ratio of 25.4:1

    2.375in hole in 17-4

    I had to do this same thing on our Genos M560, but in 4150pht. Used our 1-3/8 DS20 drill initially. Then used the Sandvik RA210 HFM with a 6" long extended shell mill arbor holder. https://www.sandvik.coromant.com/en-us/product-details?c=RA210-051R19-09M&m=5739907 Maybe with these inserts...

    Help chatter while machining a shaft (CNC lathe).

    EN24T is just 4340 here in the U.S. Nothing special just a little harder to machine. Run it about 70% as fast as you would a mild steel and you should be golden. Go to a smaller corner radius on your insert to help with the chatter and adjust your depth of cut and feed rate accordingly...

    Advice on annular cutter for 3" hole please

    Do you think a bridgeport will have the balls to cut with that cutter? That's awful large.

    Inspection station and mic. Set for non machinist operators??

    Also those little 8" square granites with an indicator are very handy for comparing sizes. Not too pricey either. Gage with a jo-block before measuring each part. Easy Peasy.

    One and done, vs 2 ops

    Quantity would most likely be the deciding factor. How many are you making now vs how many would be done in a production run? If you end up doing thousands, then something like a Speedio pallet changer would be a money maker. If it's just a hundred here, a hundred there, then 2 vises or maybe...

    Inspection station and mic. Set for non machinist operators??

    For runout and checking between centers, I recommend getting a bench center similar to this one. If you can find one on Ebay or an auction that would be best because they aren't cheap...

    Sandvik Cartridge CA tooling

    I honestly can't remember. But I milled pockets so that it was a "no shake" fit and also have screws holding it in place.

    Sandvik Cartridge CA tooling

    I made a 9" cutter 4 inserts for finish face milling some large 7075 plates on our Okuma M560. The plates were larger than our travel with a 4" cutter so I made a cutter that would cover the entire part in Y. I think we used PCD inserts but I can't remember offhand. Used a 1-1/2" side lock end...

    Why do they want thousands for a heat shrink tool machine?

    I don't need to prove you wrong. I simply don't care.

    Why do they want thousands for a heat shrink tool machine?

    Well I could say that you get the best holder life by shoving it up a squirrel's ass before you heat it up but I've yet to see anyone prove me wrong.

    Why do they want thousands for a heat shrink tool machine?

    We know it's not. But the "expensive" machines add quality of life that you can't get from a torch. Quicker swapout, quicker cooldown, which means you get back to making chips quicker. And they heat up in like 5 seconds virtually removing the need for gloves because the end mill hasn't had a...

    Making a shaft from D2 - What to look out for ?

    D2 shouldn't move but only a couple of tenths, but I haven't cut that stuff in years so I could be wrong. Is 8620 carb & harden 58/62Rc an option? You'd have to finish the diameters and lengths after heat treat though, just leave .01"-.02" on diameter. But you can have them leave threads soft...
