Fixture Materials & Advanced Manufacturing
High-Grade Fixture Materials
Our fixtures are CNC machined from certified materials to ensure maximum performance and longevity:
- 4140/4340 Alloy Steel: Heat-treated to 28–32 HRC for maximum rigidity and wear resistance
- 7075-T6 Aluminum: Lightweight alternative for high-speed applications (density 2.7 g/cm³)
- Stainless 420: Corrosion-resistant option for wet machining environments
All materials are surface ground to 0.002 mm flatness with optional hard chrome plating or DLC coating for extended life in high-volume production.

Why Brass Planetary Roller Screws
Brass (C36000/CuZn39Pb3) offers unique properties that make it ideal for precision motion control applications:
– Thermal conductivity: 109 W/m·K (3x higher than steel)
– Hardness: 80–100 HB (moderate for wear resistance)
– Tensile strength: 345 MPa
– Elongation: 35% (good formability)
– Corrosion resistance: Excellent in most environments
Our fixtures are optimized to maintain perfect concentricity and axial alignment during turning and milling, preventing thermal distortion that can affect pitch accuracy.

End-to-End Manufacturing Process
Our comprehensive process ensures every fixture meets your exact specifications:
- Customer drawing review & 3D fixture design (SolidWorks)
- 5-axis CNC machining of fixture body (Haas & DMG Mori equipment)
- Precision grinding & wire EDM for locating pins
- Fixture validation on customer machine model
- Brass screw production: high-feed turning + thread milling
- 100% inspection with CMM and functional testing
Production Capacity: Up to 50 fixtures per month with lead times 10–18 days
