Progressive Die for Precision Terminal Stamping
A 24-station progressive die holds terminal features to ±0.01 mm at 400 SPM, with SKH51 punches running over 2 million strokes between regrinds.
PROJECT OVERVIEW
"A terminal stamping program required a high-speed progressive die holding tight feature tolerances across a long production run. Previous tooling suffered punch wear and burr growth, requiring frequent die stops for regrind."
PAIN POINTS
- Punch wear causing burr growth within 300,000 strokes
- Tight tolerance (±0.01 mm) drift on critical terminal features
- Die stops for regrind every few weeks
OUR SOLUTION
- 24-station progressive die with SKH51 punches and TiCN coating
- Precision ground die plates with ±0.002 mm guide alignment
- Die tryout on our own press with CMM-verified sample parts before delivery
MEASURED RESULTS
| Punch life | 2,000,000+ strokes between regrinds (SKH51 + TiCN) |
| Feature tolerance | Held at ±0.01 mm across the run |
| Stamping speed | 400 SPM sustained |
| Burr height | Within 5% of material thickness throughout |
