Renishaw A-5000-7808 Cmm Ball Stylus 1mm Ruby M2

Product Description

The RENISHAW A-5000-7808 is a CMM ball stylus designed for use with coordinate measuring machines in precision metrology applications. It features a 1.00 mm ruby ball tip mounted on a solid carbide stem and threads into M2-compatible CMM probe systems. The overall length is 20.00 mm with an effective working length of 7.00 mm and a stem diameter of 0.71 mm. Ruby is selected for its hardness and resistance to wear, making it well suited for high-cycle inspection routines. Carbide provides stiffness and minimizes stylus deflection during probing. Metrology technicians and quality control professionals install this stylus in production and inspection environments.

This stylus is used in dimensional inspection workflows on coordinate measuring machines requiring M2 thread styli. It fits applications where a small ball diameter is needed to reach tight features, bores, or recessed surfaces. Typical environments include machine shops, quality labs, and manufacturing facilities running automated or manual CMM inspection programs. The 1.00 mm ball diameter makes it appropriate for probing fine detail features that larger styli cannot access reliably.

Key Features

• 1.00 mm ruby ball tip for wear resistance and consistent probing accuracy
• Solid carbide stem minimizes deflection and maximizes stiffness
• M2 thread for compatibility with standard CMM probe bodies
• 20.00 mm overall length with 7.00 mm effective working length
• 0.71 mm stem diameter suited for probing narrow or recessed features

Compatibility

Designed as an OEM-style replacement or standard M2 thread ball stylus for coordinate measuring machines accepting M2-threaded styli.

Installation Notes

CMM styli should be installed and changed by qualified metrology technicians following the CMM manufacturer's qualification and recalibration procedures. Power down or pause any active CMM program before changing styli to avoid probe damage. Handle the ruby ball carefully during installation, as chips or contamination on the ball surface will affect measurement accuracy. After installation, run the appropriate stylus qualification routine before taking production measurements.
