    This is why you make sure everything is documented, even verbal conversations, back them up with an email. Part and rev numbers on the prints and POs to cover your ass, and ONLY make parts to print....

    It is called "sales pitch", it really means they hope there are no problems. Hope it all works out, I am currently installing my spindle for the second time, motor and coupling for the third trying...

    OH, you might be surprised to find out they do matter.

    Simple part in P20 doesn't make sense to me, unless millions of shots are expected.

    Proper installation is critical to spindle longevity. I am rather amazed that rebuilders don't require it. How long are the warranties from the rebuilders you have talked to? Another good question...

    If possible you want to insert the cavities. It is more work up front but makes repairs or changes easier. If you don't insert up front at least make sure you can do it later if need be. If it is...

    What kind of mold? There are all kinds from plastic injection to hand injected bait, with far different issues to be aware of.

    What do you expect? It's a used machine. You think it doesn't have problems? I am sure it wasn't put in storage because it was working fine and they just didn't need it. I would think spindle...

    Does your PC show a Ready To Receive signal from your controls?

    I will add to the DNC4U is a great program, the first one I ever paid for. On top of everything else is it displays every signal to...

    While I have no problems with my USB converter I also have a serial port plugged into the serial port header on my motherboard. Many motherboards still have the header so it's worth checking to see...

    If shrink fit is not an option then my vote would be SK with precision collets. But I doubt you will gain much over good ER, maybe .0002" or so?

    Sure is a lot of whining that you don't get all the bells and whistles for free! If you're going to drop free Fusion over this what else is there for cad/cam that works as well, or even close, for...

    And you can know how much pressure you are applying to the face of your 4th. My 150mm Tsudakoma specs 360 lbs max. With a manual tailstock I am sure I would be overdoing it at times.

    That would be new. The time you can change to up to a year is how long to locally store a file, so you don't need the internet to open it.
  14. I never swap parts while the spindle is stopped,...

    I never swap parts while the spindle is stopped, only fixtures. 20 seconds per fixture/ 8 parts swap, hard to beat that. No 4th so that kills this idea.
  15. You won't. The time savings of increased...

    You won't. The time savings of increased efficiency should cover the extra time to drill the parts, the loading time savings alone should more than cover the time to drill the holes. PLUS there is...

    You don't need an internet connection for Fusion to work. It only needs to log in once every 2 weeks.
  17. If you don't mold it then I would set it up on...

    If you don't mold it then I would set it up on the 4th axis in a multi-station vise so I could hold more parts and finish them in 2 ops. The vise shown would hold 16 parts but I think 8 would be the...

    My shop is on a 70 amp breaker, then 60 to the 10hp PP. I too bucked the single-phase voltage down with a Dongan from PP. I run a 10hp VMC, 4hp compressor, heat, and everything else needed in the...

    I think they are the older versions of 10. I left mold making in 97 so it's been awhile.
  20. Don't talk to mold makers as they don't know how...

    Don't talk to mold makers as they don't know how to run a mold, talk to the people running them. I worked for a sailboard components company that bought their own press to do it in house so I got to...

    We only had a 1992 200 ton press and it worked fine. We only had boost and hold to play with, nothing at all fancy that computer controls brought.

    How much does a finished part weigh?
  22. Having both made and run, for years, molds made...

    Having both made and run, for years, molds made of both materials aluminum is hands down the best material to make molds from. It will draw heat from the part much faster for faster cycle times, and...

    First thing to figure out is shot size. The biggest question here is can you core the part out so it has consistent wall thicknesses. If not the shot size will go way up, and the cost of the...
  24. If you can't core it out then chemical foaming...

    If you can't core it out then chemical foaming agent will be needed. The foaming agent is REALY interesting if you have never used it. You get a solid wall along the cavity with a foamed center. You...

    IF you penciled it out I am pretty sure molding would look pretty damn rosy. You would probably pay close to the same for finished parts as you do the extruded plate, if you don't count the cost of...
