How to Choose a Double-Head Saw for Aluminum Windows
Compare usable cutting length and section size at the required angles. A double head cutting saw for aluminum profiles can size both ends in one setup when the member fits its working range.

How to prove the saw fits the job
For mitres, state whether length is measured at the long point or the short point. Ask for minimum cut length at each angle with the actual supports and clamps. Cut rails and stiles from production stock, then check frame diagonals, visible marks and corner gaps after dry assembly. If each cut member also needs holes or slots, compare the standalone saw workflow with combined cutting and milling on the same batch.

What to prepare
Build a trial cut list from your orders. Include the shortest bead or frame member, a long rail, and both handed mitres if they occur in production.
What to check during the trial
Check usable cross-section and minimum length at each required angle. Measure from the correct long or short point of the mitre, then assemble a sample frame to reveal cumulative length and angle errors.
How to record the decision
Separate cutting time from loading, support adjustment and unloading. If a third head is being considered, identify which recurring cut sequence would actually use it.
