I think they would wear away far to quickly to be practicle for a cutting CNC machine, laser or plotters yes but not spindle cutting machines.

Extrusion is soft stuff to start with so would wear away quickly if used with Aluminium wheels and delrin I think would wear very quickly unless rails kept spotlessly clean even then leaving slop after a short while.?

Too many grey areas for my liking.!!

Yes you are correct in that this type of extrusion is far more suited to a laser cutter/plotter or something like a plasma cutter which does not exert a huge amount of force. The extrusion would ideally be steel if it were for a router/mill. That said, as I will be getting a tool made it is possible to look at the strengthening the profile. Does anyone have some data or a formula to work out what forces a mill or router could exert against the rail. Assuming the rail would be far far cheaper than anything else on the market it could even be possible to run two sets of v-track on either side.

I work for a company that sells a lot of extrusions in the flooring industry. I managed to twist the bosses arm into making dies for a 45*45. 45*90,90*90 extrusions. We also had a rail support made for round bar that slots into the T slot, but needs to be screwed in from the opposite side. My latest arm twist is a tslot table but it is only134mm wide.You can use the Sbo 16 uu/20/25 round linear bearing. Works quite well and is fairly cheap compared to square rail. Hope this helps
