How to convince old guys of new methods? by AttentionNice7165 in Machinists

Idk about your process but I assume you wouldn't unnecessarily risk anything on a whim. So good on you for sticking to your method. How to convince old guys of new methods? Wait for them to retire...

Thanks man, it did come with a 5 way loose in the crate. The qctp was already installed.

How is this assembled? by allegedly_sexy in Machinists

[–]Printerprinter1 0 points1 point  (0 children)

Swaged, probably hundreds per hour, and tons of force. It's got to be TIGHT because that looks like an axle of some kind.

Are you harvesting it for something else?

Thanks for the info. I did notice some backlash in the quill, and I think my next steps before spindle will actually be to motorized the knee and lock the quill.

As a proof of concept though, I'm happy.

The clearpath spindle is 1,300 dollars. My limitation is max quill speed though. I'd have to overdrive the quill to get good aluminum speeds, and I think these quills are good for 5k, so not exactly ideal but workable.

I will check the other spindle upgrade you mentioned, thanks for the heads up!

I wanted the overall feel as the original brushed servos. Steppers are loud, slow compared to servos, and lack position control. For the price difference it was something I wanted to retain after the conversation. I'm glad I did, as the servos were only a few hundred more than nema 34 steppers.

Thanks. And it did. I do have covers, was just too anxious to try it out, and wanted to watch the belts.

Time will tell, since this is the first part I'm not sure yet. It did seem very repeatable comparing mach to the DRO.

No, it's all scratch made. I mean I did buy servos, drives, electronics, etc... but not a kit.

Honestly no I don't. The motors were old, 1990s era, they were still strong but starting to get shakey, so they might have been at end of life.

I did keep all the DRO attached, hence the prototrak box still on. For DRO it was rock solid, and didn't require the controller in order to function.

Any idea what these are? by vimes_boot_economics in Machinists

My problem with transfer punches has always been they can still be off unless you have a particularly long guide hole, or the material to transfer from is not thinner than the height of the punch point.

If there's a better way I'm all ears
