    As others have said I think there are niche areas where 3D printing in metal is going to replace all other techniques, but there is no way it's going to displace all machining unless there is a...

    This is something I've been looking into for a while, as I hate having my shop being so loud that I have to wear ear plugs... My goal is to get the shop to the point where it's under 70db all the...

    Gotcha! Well I'm honestly not sure what the service interval or process should be for a bearing set like that, most spindle noses will have a labyrinth seal (a non-contact rotating seal) that should...

    You don't just 'pack grease' into a precision spindle bearing set... The exact amount of grease has to be controlled very carefully, otherwise it will cause overheating and shorten the bearing life...

    Honestly I have looked into building small machines like this many times. The conclusion I keep coming to is that building my own can never be competitive with buying a VMC used... If you have the...

    Drilling it with a standard carbide drill will be pretty straightforward, especially given the thin case. I have used AITiN coated carbide drills from Maritool to drill many many 1/8" diameter holes...

    I have never really seen a 'one stop' resource unfortunately, because there are a *lot* of different approaches for all the different parts and which one is right really depends on what sort of...

    If you have a VMC15 in good condition locally for a decent price, jump on it!

    The VMC15 was the 'little brother' in the lineup, but that does not mean it wasn't a capable machine. Mine runs 8-10...

    Really glad you got it sorted out mate! I actually had to replace the CRT monitor in my Fadal this morning, and I thought about your issues before I got the new screen in! I had my fingers crossed it...

    Gotcha, makes sense. The anti scale I mentioned (ATP641) is not borax based and is fine to use in an electric furnace. ATP641 from Brownells has worked well for me many times in an electric furnace...

    Any temperature over 400ºF will start growing an oxide layer on the part. Any temperature over about 900ºF will start causing decarburization/scale (albeit slowly at first). Best thing is to protect...

    Yes it does, a lot! Oil quenching A2 will leave you with a piece so hard that it will be difficult to temper it back to something reasonable, the part will also have very low toughness and may crack...

    You'll have to go through his posts as he has quite a few about milling different parts from carbide. You might want to reach out to him for advice, in my experience he's been very helpful whenever...

    OP did not tell us carbide grade, so there's no need to jump down my throat. Adam seems to have good luck machining what I imagine is a variety of Carbide grades, mainly as inserts for dies. I was...

    Yes machining dry and HSM go hand in hand. You can slot mill dry, but it's definitely going to leave more heat in the part than trochoidal milling the same feature. Proper coating on the tools is...

    Look up 'adam the machinist' on instagram. He routinely CNC mills carbide on his Mori or HAAS using tooling from Union. Pretty cool process and seems like it might be a good fit in this application. ...

    By the way: after cold start the machine asks you if you want to move to the home position, if you say NO it actually wipes the home position I believe, so always say yes lol!

    This may be a dumb question, but given that you're only machining steels is there a reason to use coolant at all? Cutting dry with AITiN coated carbide tools works very well for me machining both...

    Sounds like the other guys have you sorted out!

    One thing worth remembering is not to move the 'home' ('SETH') position around if you have fixture offsets saved. The fixture offsets are all stored...

    One thing worth noting from this: the reason the blasted part is so much rougher is because it was blasted with high pressure. Low pressure bead blast will produce dramatically different results.

    They look great! I guess the etch really smooths out the appearance of the tumbled part!
