Cost Optimization for a 1980 mm Aluminum Linear Base
Customer Challenge
Customer needed a 1980mm long aluminum linear base with extremely tight straightness and flatness requirements. Full CNC machining from solid billet was prohibitively expensive due to material waste and long machining time.
BestField Solution
BestField proposed a hybrid approach combining aluminum extrusion for the basic profile with secondary CNC machining for critical features. This significantly reduced material costs and machining time while maintaining required tolerances.
Technical Details
- Length: 1980mm
- Material: Aluminum 6061-T6
- Critical straightness: 0.01mm over full length
- Critical flatness: 0.01mm on bonding surfaces
- Critical hole tolerance: ±0.01mm
- Bonding surface roughness: Ra 1.6
- Finish: Clear anodizing after machining
Result
Cost reduced by approximately 45% compared to full CNC machining approach. First article inspection completed successfully and customer validation passed. Production lead time reduced from 4 weeks to 2 weeks.
Precision Medical Instrument Components
Customer Challenge
Medical device manufacturer required small, complex stainless steel components for surgical instruments with tight tolerances and biocompatible surface finish. Parts needed to withstand repeated sterilization cycles.
BestField Solution
BestField utilized precision CNC machining with Stainless Steel 316L, followed by electropolishing and passivation to achieve the required surface finish and corrosion resistance. Full traceability documentation provided.
Technical Details
- Material: Stainless Steel 316L
- Tolerance: ±0.01mm on critical features
- Surface finish: Ra 0.4 after electropolishing
- Passivation per ASTM A967
- Lot traceability maintained
- Clean room packaging
Result
Components passed all biocompatibility tests and sterilization validation. Customer achieved FDA clearance for their medical device. Consistent quality across production batches with zero rejections.
Aerospace Bracket Weight Reduction
Customer Challenge
Aerospace customer needed to reduce weight of existing aluminum bracket while maintaining structural integrity. Original design was over-engineered with excess material.
BestField Solution
BestField engineering team performed topology optimization and redesigned the bracket with strategic material removal. Utilized 5-axis CNC machining to create complex lightweight geometry with internal pockets and thin walls.
Technical Details
- Material: Aluminum 7075-T6
- Weight reduction: 35%
- Maintained load capacity
- 5-axis CNC for complex geometry
- Hard anodizing for wear resistance
- FAI per AS9102 standard
Result
Achieved 35% weight reduction while maintaining all structural requirements. Part passed fatigue testing and received customer approval for flight hardware use. Design became template for similar components.
