Renishaw A-5003-7306 Cmm Ball Stylus 6mm M4 Ruby

Product Description

The RENISHAW A-5003-7306 is a CMM ball stylus designed for use with coordinate measuring machines in dimensional inspection and quality control applications. The stylus features a 6 mm ruby ball tip mounted on a carbon fiber stem, with an overall length of 50 mm and an M4 thread for secure attachment to probe heads and extensions. Ruby is the preferred ball material for CMM styli due to its hardness and dimensional stability, making this stylus well suited for high-repeatability contact measurement tasks. Licensed metrologists, quality technicians, and CMM operators are the primary installers and users of this component.

This stylus is used in coordinate measuring machine setups found in manufacturing inspection environments, tool rooms, and quality assurance labs. It is appropriate for both production floor and laboratory CMM installations where precise dimensional verification of machined or fabricated parts is required. The M4 thread is a common interface for Renishaw-compatible probe systems, making this stylus a practical replacement or additional probe configuration for existing CMM setups.

Key Features

• 6 mm ruby ball tip for high hardness and dimensional consistency
• Carbon fiber stem reduces mass and minimizes thermal expansion effects
• 50 mm overall length suits a range of part geometries and probe reach requirements
• M4 thread interface for compatibility with standard CMM probe heads and extensions
• Single-piece construction typical of Renishaw OEM styli for reliable, repeatable contact

Compatibility

Designed as an OEM-style replacement stylus for CMM probe systems using M4 threaded connections. No specific compatible model numbers were provided in the product data.

Installation Notes

CMM styli should be installed and replaced by qualified metrology technicians or CMM operators following the CMM manufacturer's probe qualification procedures. Power down or place the CMM in a safe park position before changing styli to avoid probe crashes. Use the recommended torque driver if specified by the probe head manufacturer - do not overtighten, as ruby balls are brittle and stems can be damaged. After installation, always re-qualify the stylus using the CMM's built-in calibration routine before taking measurement data.
