Pain point:
Post-turning drilling → 25% scrap rate + tap breakage
Solution:
B-axis mill-turn single setup:
Turning (OD/ID/grooves) → B-axis indexing → 24-hole milling+tapping
Result:
0% scrap｜Cycle 41→18min｜6k PO same-day
Industry myth:
"Ra 0.3 requires broaching/grinding after heat-treat."
Breakthrough:
• Post-HT in-situ machining
• 5-axis + Ø3mm lollipop cutter
• 18k rpm + 0.03mm step-over
Data:
120-teeth spline Ra 0.27-0.31｜100% FAIR pass
Bottleneck:
3-axis VMC → 30+ setups → 9 weeks
Process redesign:
1. 5-axis rough milling (simultaneous)
2. Mill-turn finish turning (1 transfer)
Outcome:
Lead time 9w→13 days｜0% helium leak
Failure mode:
Hex milling → transfer → threading → 100% dinged hex
Cure:
Swiss mill-turn full process:
Guide bushing → hex milling → threading → zero handling
Win:
Cost 6.80→4.10｜0% damage｜100% gauge pass
Mission Impossible:
6-week launch + 200pcs + turning/5-axis → suppliers quit
Execution:
Dedicated capacity:
• 3 mill-turn cells priority allocation
• 40+ material grades in stock
Record:
Mon AM drawing → Next Tue 200pcs 2507 duplex valves shipped → Client secured Series A
