Spi Z3010 Cmm Ball Stylus 1mm Ruby Point M2 Thread

Product Description

The SPI Z3010 is a coordinate measuring machine (CMM) ball stylus designed for high-precision dimensional inspection. It features a 1 mm ruby ball tip mounted on an M2 threaded shank with an overall length of 20 mm (approximately 0.787 inches). The ruby point provides excellent hardness and wear resistance, making it well-suited for repeated contact measurements on tight-tolerance features. This stylus is installed by metrologists, quality technicians, and CMM operators working in manufacturing, tool and die, aerospace, and general metrology environments. Its compact ball diameter makes it appropriate for small-bore and fine-feature probing applications.

The Z3010 is suited for use in inspection cells and metrology labs where tight-tolerance surface and feature measurements are required. The M2 thread interface is a widely used standard in CMM stylus systems, allowing integration into multi-stylus configurations and extension assemblies. It is commonly deployed on CNC CMMs and manual CMMs in production and quality control settings where repeatable contact measurement of small geometric features is necessary.

Key Features

• 1 mm ruby ball tip for precise, wear-resistant contact measurement
• M2 stylus and probe thread for broad compatibility with standard CMM systems
• 20 mm overall length suitable for shallow-feature and general-purpose probing
• Ruby point material provides high hardness and low surface adhesion for consistent results
• Compact ball diameter enables access to small bores and fine geometric features

Compatibility

Designed as a standard M2-threaded CMM ball stylus compatible with CMM probe heads and stylus extension systems that accept M2 thread connections.

Installation Notes

CMM ball styli should be installed and changed by qualified metrology technicians or CMM operators. Before changing a stylus, power down or pause CMM motion and follow the machine manufacturer's stylus-change procedure to avoid probe damage. Use a calibrated qualification routine after any stylus change to requalify the ruby ball center position within the CMM software. Avoid applying excessive torque when threading the stylus into the probe head, as overtightening can damage the M2 thread or dislodge the ball.
