Schaublin 125-CNC retrofit.

@ SMC.Collins - I like the Feral Engineers linuxcnc videos on youtube. That would be a good place to start.

Here is this weeks video...

Our #1 fan Nico shot down my first plan for this part...

Thanks for the new vid!

I bet those adapter holes were threaded from the factory and got wallowed out... subsequently replaced with screws & nuts by a ham-fisted owner or mechanic.

Tapping arm vs. light: mount the light with a longer stud and nut and have the anti-rotation bar internally threaded.  When you need it just thread it on to the exposed threads. Put a rubber cap over the exposed stud when you're not using the tapping head to keep the chips & snot off.  Feel free to lose the cap at the first opportunity.

Lathe threading overrun clearance: Insert mfgrs publish the dimensions of inserts (or you can approximate with calipers).  You'll need the tip center to insert edge, plus any angled lead-out, plus a bit for shoulder clearance.  On small threads with a shoulder I usually just pull straight out and skip the angled lead-out.  Assuming you've modeled the insert & holder properly, CAM tool path simulation is extremely helpful here. 

Cheers,
Ralph

Hi Andy,
If anyone reads this and missed what Andy is referring too:


Yeah, I was too lazy to check the insert and just guesstimated it. Duh!
I really , really want to install Lathe Macro's, but have the mismatch between my LCNC Version and your macros needing the latest. Rather than trying to work out how to install the beta version of the next LCNC, I was just waiting till it releases.

I think you are right. Mounting that heavy steel fan on threads cut in 6mm aluminium seemed like a poor design choice from the start. Bolting it with too large nuts was no better. The funny thing is that the final failure seems unrelated to the two bolts through the hub, or the nuts denting the radius.

To be honest, I would be better off making a new spindle light with 4000K LEDs, as the current one is way up past 6500K, and totally screws up my white balance. If I make it, I would epoxy in a few magnets to mount it, freeing up the screw hole.

If you'd use the Maho a bit more the dried coolant snot would yellow up the light nicely and save you the trouble.

LMAO!!! Brilliant.

Hi Andy,
That is the sort of overview I was hoping for when I first went to your Github. If I had that, I would have installed the correct version straight away.

Probably my lack of familiarity with Github, as I didn't know to look to "release" on the RH side. Thanks for the clarification.
Maybe I can get it installed this weekend.
