High Precision CMM Styli | Ruby Ball Probe Styli M2–M5 Custom

High Precision Styli for CMM Measurement Systems

Our premium styli are essential components in coordinate measuring systems, designed to deliver accurate and repeatable measurement results. These styli make direct contact with the workpiece, transmitting precise signals through the probe system to ensure reliable data acquisition.

Superior Material & Precision Manufacturing

All styli are manufactured under strict CNC machining standards to guarantee exceptional rigidity and dimensional accuracy. The probe balls are produced with high sphericity and consistency, ensuring optimal performance in demanding inspection environments.

Ball Materials Available:

• Ruby
• Silicon Nitride
• Zirconia

Ball Grades:

• G3 / G5 / G10

Shaft Materials:

• Aluminum
• Carbide
• Carbon Fiber
• Ceramic

Designed for Accuracy & Stability

The rigidity of the styli and the roundness of the probe ball are critical factors in measurement performance. Poor-quality styli may lead to deformation, positioning errors, or inaccurate data collection.

Our styli are optimized to:

• Minimize deflection during measurement
• Ensure stable and repeatable probing
• Maintain high accuracy even in complex geometries

Wide Compatibility & Customization

We offer a full range of styli from M2 to M5 threads, compatible with various probe systems. Custom designs are available to meet specific measurement requirements, including length, ball diameter, and material combinations.
