  1. MACOR GLASS CERAMIC advice needed - VMC

    I've been asked to quote this. We would run these in the Haas VF-2ss which has 12,000 RPM and thru coolant. I have never dealt with this material before, but there is quite a bit of information...

    I ended up buying a Prusa. It's smaller than I would like at 250 x 210 x 210mm build volume, but I was more attracted to the apparent overall quality of the printer itself, and mainly the software...

    I should have been more clear. I need 300x300mm build plate minimum, and wouldn't mind 400x400 if the bed doesn't take 3 hours to heat up.

    Drill press. I almost never wear safety gear, but I...
  4. Long shot: Suggest a 3D printer

    I bought a $300 Monoprice Maker Select (basically a toy) to prototype a product and thinking I might play around with it a little bit. I'll be damned if I'm not using the thing every other day to...

    Thanks Street, the waterjet issues you talk about are exactly what I was afraid of.

    Ox ended up sending me contact info for a small molder, and I just cut a PO yesterday for 10 prototypes. $300...
  6. Water Jet / Die Cutting or...? 1/4" thick natural rubber 'tires', Ø2.15" OD

    Open to suggestions on how to make these. I worry about waterjet and the typical 'tit' left at the start / stop location on the OD. I can tolerate maybe a .020" high tit, but that's just a...

    Believe it or not, these two are actually worth putting time in to. Both have real drive to do a good job, but need a lot of help getting there. One is starting from scratch, and one was taught...

    Thanks for all the replies fellas. Unfortunately it seems that I'm on my own for visuals. I suck at teaching because I just "see" this stuff in my head and have a hard time explaining it, and I...

    New Hire Training - Mill Offsets

    I've got two new guys that are both struggling with mill tool and work offsets. Youtube has a seemingly endless supply of videos about how to SET offsets, but I need help teaching these guys how to...

    Probably 50% of what we machine is plastics. Ultem, Acetal, FR-4, Polycarb, Semitron, Torlon, you get the idea. Going on 13 years now and have never, ever had an issue with coolant due to plastics....

    1) I pay $124.40 per set (Deltronic +/-.0012" sets) in your size ranges from Western Tool.
    2) Tight tolerances are expensive. Your customer should be the one paying for something like this, not...
  15. The worst part about small lots is the coolant. ...

    The worst part about small lots is the coolant. It's spendy getting the coolant ready with additives or even changing a sump out completely.

    We never had an issue with porosity, and all the mag...

    My experience is with AZ31, which is a cast plate. Not sure about other alloys, but this alloy is only available in plate as far as I remember... this was 8 years ago I think. I bought a type D...

    Yes they are a little pricey, but tenth increment pins give you so much confidence in what you're doing, you'll forget about the price in short order.

    Also, air gaging only goes down to .040" to...

    You guys have seen a Haas do a tool change after running thru coolant? Everything, (tool shank, spindle taper, ball grippers and everything else) is dripping wet with coolant. I'm thinking that...

    Huh, I guess I missed something good. What finally got him the banned? Please tell me Boris was resurrected and got him with Mr. Slammy.

    No CAM on the premises?

    Damn. If this is true, then I feel like an idiot for sticking up for them. Sounds like just another dumb shit after all. Sigh. People suck.

    Thanks for the update.

    In my experience you are right on. Flat billers, Bro Dozers, and the type that thinks it's funny to blow their fucking train horn when passing pedestrians. In general, giant dooshers.
