Product Description
- Annular structure dimensional tolerance of IT3 grade (error <0.005mm)
- Thickness uniformity within ±0.003mm
- Optimized load force distribution with ±2% variance in multi-plate parallel configurations (2-8 discs)
- Consistent load multiplication ratios (3.2-4.5x at 0.5mm displacement)
- 50CrVA (1.05Cr-0.8V-0.25Mo): Quenched at 860°C and tempered at 420°C to achieve HRC 45-50 hardness and 1800MPa tensile strength
- SUS304 (18Cr-8Ni): Solution annealing at 1050°C for enhanced corrosion resistance
- Dynamic stiffness testing (150-300N/mm)
- 10⁶ cycle fatigue testing (preload decay <5%)
- Dimensional metrology via CMM
- Reduces spindle runout to ≤2μm
- Improves machining accuracy to ±0.001mm for aluminum alloys
- Enhances thermal stability during prolonged cutting operations
- Operates reliably within -40°C to 120°C temperature range
- Grooved design: 4 equally spaced lubrication channels (width 0.8mm, depth 0.5mm) to minimize friction heating at high RPM
- Grooveless version: Shot-peened surfaces (Almen intensity 0.2A) for extended fatigue life
