    Re: Chinese 2.2kw spindle burned out?

    Yes, the Deckel had a 3/4 Hp 3 phase 3,000 rpm motor on it which makes it less saleable to the gen unwashed etc.

    For another A$100 for the VFD it immediately put the Deckel into the must have...

    Re: Chinese 2.2kw spindle burned out?

    Tank you..…...just bought one of "those" drives to go with a Deckel D bit grinder that I sold on Gumtree to make it more saleable for running on single phase......2.2Kw 3Hp etc, A$80 on Amazon.

    Re: Chinese 2.2kw spindle burned out?

    In that link it states that an analogue meter can read the VFD voltage because it doesn't move quick enough to dip when the voltage goes low during the ramp up to full voltage etc, so for the test...

    Re: Chinese 2.2kw spindle burned out?

    My 2 pennoth worth if applicable...…….to test it, could you wire the apparent faulty VFD in question to a common 50/60 Hz 3 phase motor and see if it will run and speed up and down?…..just asking.

    Re: CNC router build

    Hi, what are you using for the vacuum part? …...I just "found" a vacuum cleaner, sans the suction hose, on a nature strip and it still runs.

  6. Poll: Re: Machinist or Machine Operator? You decide..

    Hmmmmm, good thing too, I wouldn't really want a "thing" that anticipates my needs making decisions I might not like afterwards.

    I would, however, like to see AI adapted to a 'phone answering...

  8. Poll: Re: Machinist or Machine Operator? You decide..

    I would say that a device that is controlled by AI has an autonomous freedom to decide about an outcome irrespective of the directive given, the only constraint is that it will be switched off if the...

    Yep....when I bought some CBN wheels for my Cuttermaster I found them on a Ukrain seller's listing.

    In that case the choice is yours...…..a driverless Uber taxi once killed a woman …..I think this was a few months back.

  11. Re: Limitations of cheap 4th axis components off eBay?

    LOL, well Rog, never mind the quality, feel the width.

    Maybe the term "harmonic" generated a thought that due to the noisy gearbox it was a harmonic drive.....it's all in the interpretation.

  12. Poll: Re: Machinist or Machine Operator? You decide..

    Well, I would go back to the origins of automation, possibly in France if my knowledge is correct, and put the Jaquard loom control as the absolute forerunner of the automation industry.

    Re: Tips for straighter bores

    As the actress said to the Bishop, there are many ways to do it.....reaming with a rigid tool is just one way, and the required quality of the end product dictates how you get there.....also, and...

    I wouldn't go predicting anything regarding the future these days....as soon as something is state of the art and selling like crazy it gets superseded by a cheaper model and the whole shebang goes...
  15. Poll: Re: Machinist or Machine Operator? You decide..

    Well, as I understand it the more practical approach is to make pattern parts, not the actual metal whatever item, that can then be converted to metal.

    I think this is a bold move that has...

    Re: Tips for straighter bores

    If you aren't into reamers for hole sizing then you have missed the plot completely......even odd size holes will profit from a reground reamer if the volume is great enough.

    As I said, a reamer...

    What you say is very true Bob, the big defining difference is when you have no tangible competition you will ultimately fail mainly due to complacency and losing the need to diversify.
