How should ATC tool-to-tool change time be defined and verified in a purchase contract to avoid acceptance disputes?
• Contract must define T-T as adjacent pocket exchange, excluding spindle orientation and clamp/unclamp time.
• Verify with laser timer or high-speed camera, average 10 consecutive cycles.
• Disc magazine 24 pockets typical T-T ≤1.5s; chain magazine ≤3s.
• Repeat under load with maximum tool weight (e.g. ≤8kg).
