PM727M Bearing Pocket Test

PM-727M CNC Conversion Series
In this video I mill a couple bearing pockets to check for symmetry and accuracy. I machine these pockets with Backlash compensation turned off , I'm very pleased with the results very tight tolerances.
I will leave backlash comp turned off.
I have tried to be as detailed as possible to the point of being informative but not boring. I will try to keep the videos around the 15 minute mark. Please comment and let me know if the content is spot on or you would like more information and details. I will do a complete overview video to conclude the wiring in which I will go thru how the system operates. Thanks for watching , please subscribe, thumbs up if you like the video, and most importantly , Be Safe!

Nice! Your attention to detail payed off.

Nice . Some tool runout probably took care of the backlash you mention. Great job.

[svsoulmate]

Nice Sam! A lot faster then the mini mill huh.

Nice, I knew it worked out😀Happy 2017!

great work on your tolerances but I think you could use better tool pathing strategies, I highly recommend fusion 360 as you'll be able to take a roughing cut then a finishing pass and be able to use more or your tool instead of just the tip which will give you better tool life. but all in all very impressive.

How do you protect the stepper motors from the coolant?

[Ndjjohnson]

what do the pockets measure out at? Are you over or under? Like plus 1 thou?
