Thermal-Break Aluminum Profile Machining Checklist
Mark the insulating strip, aluminum walls and restricted areas on the approved profile section. Overlay holes and pockets from the finished drawing. Have the profile system supplier confirm the approved process where a feature approaches the thermal break.
What needs checking before the first cut?
Mark the insulating strip, aluminum walls and restricted areas on the approved profile section. Overlay holes and pockets from the finished drawing. Have the profile system supplier confirm the approved process where a feature approaches the thermal break.
How to accept a sample
Use the actual finish and check that clamps neither shift the part nor leave unacceptable marks. Measure pocket depth, location and remaining material against the drawing, then fit the specified hardware. Check both hands when production uses mirrored parts. Record the drawing revision, fixture and program used so the trial can be repeated.

What to prepare
Mark the thermal break and every restricted area on a section drawing. Verify the cutter path against the aluminum walls and the approved profile system requirements.
What to check during the trial
Check fixture contact on both sides of the section. For thin or asymmetric members, trial clamping on scrap and inspect for movement or marking before using finished stock.
How to record the decision
Inspect slots and holes after deburring and confirm that hardware clears the insulating strip. Refer uncertain features to the profile system supplier for approval before production.
For thermal break aluminum window profile machining, inspect the isolation strip after deburring as well as immediately after cutting. Use the system drawing to identify surfaces that must be left intact.
