Three Steps to Select The Right Stylus
1.Based on workpiece material:
▪ Hard workpieces (steel/titanium) → Stainless steel or tungsten steel probe.
▪ Aluminum/cast iron → Silicon nitride/zirconia ball head, avoid ruby.
2.Based on accuracy requirements:
▪ The shorter the probe, the better; the larger the ball, the better; the fewer components, the better, to reduce bending and connection point errors.
3.Based on machine tool vibration:
▪ High vibration → Carbon fiber probe (excellent vibration damping).
Avoid using ceramic probes in high-vibration applications.
▪ Hard workpieces (steel/titanium) → Stainless steel or tungsten steel probe.
▪ Aluminum/cast iron → Silicon nitride/zirconia ball head, avoid ruby.

A Guide to Stylus Materials Science
The correct combination of the ball head and shaft can reduce the impact of measurement uncertainty to less than 10%.
Measuring ball material
Rubi
Extremely hard, with a smooth surface. ⚠️ Avoid using on aluminum parts (adhesion).
Silicon nitride
Wear-resistant, non-alumina compatible, suitable for aluminum alloy measurements.
Zirconia
Extremely high fracture toughness, suitable for cast iron and rough surfaces.
Ceramics
Lightweight and insulating, used in applications with special insulation requirements.
Probe material
Tungsten carbide
Deformation resistant, suitable for small diameter/standard probes.
Cerâmica
Lightweight and thermally stable, suitable for long probes and production environments.
Carbon fiber
Weighing only 20% of tungsten steel, it is used for ultra-long probes and high-vibration machine tools.
Titanium alloy
Good rigidity, suitable for applications requiring weight reduction.
