Spi Z3000 Cmm Ball Stylus 1mm Ruby M2 Thread

Product Description

The SPI Z3000 is a coordinate measuring machine (CMM) ball stylus designed for high-precision dimensional inspection. It features a 1 mm ruby ball tip mounted on a stylus with an overall length of 10 mm and M2 thread connections on both the stylus and probe ends. Ruby is the preferred point material in CMM applications due to its hardness, low friction coefficient, and resistance to wear, making it well-suited for repeated contact measurement cycles. This stylus is installed and used by metrologists, quality control technicians, and manufacturing engineers performing tight-tolerance inspection work.

This stylus is suited for use in precision metrology environments including quality labs, production floor inspection stations, and tool and die shops. The compact 1 mm ball diameter allows access to small bores, narrow grooves, and fine surface features that larger styli cannot reach. The M2 thread is a common standard in CMM tooling and allows this stylus to interface with a wide range of CMM probe bodies and stylus extension systems.

Key Features

• 1 mm ruby ball tip for fine-feature and small-bore inspection
• 10 mm overall length for compact, low-deflection measurement reach
• M2 stylus and probe thread — standard CMM tooling interface
• Ruby point material offers high hardness and long wear life
• Single-piece package suitable for individual replacement or kit expansion

Compatibility

Designed as an OEM-style replacement or supplemental stylus for CMM probe systems using M2 thread interfaces. Verify thread engagement and stylus reach requirements against your specific CMM probe body before installation.

Installation Notes

CMM styli are installed by metrology technicians or CMM programmers. Power down or pause the CMM and retract the probe before changing styli to avoid damage to the probe head. Use proper stylus torque tools or finger-tighten only as specified by the CMM manufacturer — overtightening M2 threads can damage the stylus or probe body. Recalibrate the probe after any stylus change to ensure measurement accuracy.
