I like how you did the Honda plugs, real neat install. Can't ever get all the chips out can you...

Looking real good, be in production soon I'd bet.

Looks pretty smooth, very nice. With all that work you did to get the turret servo on there, I was hoping to see the turret index. Anyway where did you get the pulleys and belts for the axis drives? Also what Mesa cards are you using on this one?

Hey rob


How much different is the chnc from the hnc other than the enclosure ?

Your machine is very impressive, love the coolant. and is it set up for constant surface speed?

this is one thing i do keep meaning to make a video off
but as CHNC is used for 2nd opp work 99% of the time, i never realy have a good video to make of turret index's as we allways gang up 2 or more tools on the square turret you see.

but turret is working perfect, it does realy want a new gear in there tho. to make it truly zero backlash on the worm and 3 gears..
we are so bussy tho we dont realy have time or urgent need for it. only thing we need to fix is the collet coloser as that thing just eats air now. looking to put a new hydrolic unit on.

hi

the main difference is the 16C collets over the 5C collets..
a HNC is grate machine for 2nd opps and small parts.. the CHNC is also but for us not very offten we find we need the 16C size range.. as 5C would cover 80% of work gets put on it.

travels are the same on X and Y, some dont have the top parting slide with them but they both take same unit, its just Air over hydrolic tho so it eats air and can be a pain if not used for awhile, we very rarly use outs beacsue of that.

yes
constant surface speed, Rigid tapping, etc etc
anything EMC can do it can do and more.
