PM-833T DRO REFINEMENTS

[RIMSPOKE]

I FINALLY FINISHED UP MY DRO INSTALLATION NOW THAT I HAVE A CHIP TRAY UNDER PM-833T MILL .
WHAT's NEW IS A LOWER COVER FOR THE Y SCALE AND A 1/4" ALUMINUM END CAP .

THE UPPER COVER HANGS OUT FARTHER THAN THE LOWER ONE SO ANY CHIPS THAT GET DOWN THERE WILL FALL ON THE OUTSIDE .
THERE IS A DRAG CHAIN INSIDE THAT HOUSES BOTH THE X & Y CABLES .
IT ANCHORS IN THE BACK AND TRACKS PERFECTLY THROUGH THE RANGE .

THE Z AXIS CABLE ALSO RUNS THROUGH A DRAG CHAIN THAT HOUSES THE POWER TO THE MOTOR AND THE LED WORK LIGHT
THAT MOUNTS AROUND THE SPINDLE . CHIPS NEVER GO THERE BUT I MAY TRY TO MAKE A COVER FOR THAT ONE TOO .

What size drag chain did you purchase and where did you get it from?

Thanks

What size drag chain did you purchase and where did you get it from?

THE X-Y CHAIN IS 10mm x 20mm ( INSIDE DIMENSIONS )
THE Z/ POWER CHAIN IS 10mm x 30mm . ( WIDER BECAUSE IT ALSO CARRIES THE LEAD FOR THE Z AXIS LIMIT SWITCH )

I BOUGHT THEM ON E-BAY , 10 x 20 CHAINS ARE SURPRISINGLY CHEAP !

Thanks for the response, and appreciate the links.

With the open type does it get chips in between the links or is it mounted far enough away to not be a problem?
Or if it does how do you deal with that?

David.

THE Z/POWER CHAIN IS UP ON THE SIDE OF THE MILL WHERE CHIPS DON'T NORMALLY GO .
IT IS OPEN BUT I HAVE YET TO SEE ANYTHING GET IN THERE .

THE X/Y CHAIN IS MOSTLY ENCLOSED WITH THE UPPER COVER HANGING OUT FARTHER THAN THE LOWER ONE .
I RUN PAST IT WITH A VACUUM ONCE A DAY .

THE ONE SHOT OILER MAKES PUDDLES ON THE OTHER SIDE SO I AM QUITE GLAD I DIDN'T
PUT IT ON THE SAME SIDE AS THE Z CHAIN !

Rimspoke, thanks for the quick reply and as I didn't say so before very nice work on the installation of your DRO.

Cheers,

David.
