method to cut 'clear PETG tubing'
(OP)
I am looking for a simple method to cut 'clear PETG tubing'. The manufacturer only supplies in standard length and will not custom-cut for us. Wall thickness is only 0.5mm. We will cut about 300 per week.
I have tried manually cutting with a sharp knife, small hacksaw and a hot blade. The cut has to be burr-free. The hacksaw produces burr while the hotknife produces excessive melting.
Any ideas?
What is the standard method in the industry?
Cheers!

These type units are set-up to deal with continuous length production.
300 parts per week is a couple of hours work the way I described in my first post. Length tolerances are not good, however. I can hold about +/-.06" A little creative fixturing should solve that though....
Alternatively, there are simple air powered guillotine fixtures used by some manufacturers. I can't seem to find them right now. I know I've seen them marketed in Medical Product Manufacturing News. Or perhaps a local extrusion house would be willing to cut your tubes to length for a fee?
Would you mind sharing the tube OD and length requirements with us?

Drive in scapel blade that cuts upward about 4 o'clock . (Tool for this.)
Apply water drip, or if dry, air-jet, & aim directly at the incision point to keep incision cool.
Clean cut no burrs.
