Re: [CAD_CAM_EDM_DRO] Re: Plasma cnc

Yeah, the Hypertherm Powermax 1250 is top of the line
for CNC plasma operations. It allready has the remote
torch on/off terminal installed for the G-Code to run
the torch. But at $3500 I say ouch. I am also drawing
up plans for a combo plasma/router cnc machine and am
looking at drive options. The ball screws for an
5'X10' table run in the thousands of dollars. I was
wondering if anyone here has ever seen,used,heard of
chain and sprockets instead of screws? My parents have
a picture framing shop and they use a CNC mat cutter.
I was looking at the gantry rails to see what kind of
drive system was there and it's all small chain and
sprockets. a littls smaller than a bicycle chain would
be. seems like if the chain was tight enough there
would be no backlash. Since I want to use dual drive
on the long axis, I am going to need 20 feet of ball
screws, this is way out of budget at this point.
