Mitutoyo 12AAC732 Cmm Needle Stylus 45 Mm Zirconia

Product Description

The MITUTOYO 12AAC732 is a needle-type coordinate measuring machine (CMM) stylus designed for high-precision touch-probe measurement applications. The stylus features a zirconia point bonded to a slim aluminum stem with a 0.60 mm stem diameter, delivering the rigidity and low mass needed for accurate probing cycles. At 45 mm overall length with an effective working length of 37.70 mm, this stylus suits applications where reach into tight features is required without sacrificing repeatability. Installation is straightforward for CMM technicians familiar with standard stylus change systems.

This needle stylus is intended for use in coordinate measuring machine setups where a fine-tipped probe is required to access narrow bores, slots, or recessed geometry. The horizontal mounting orientation makes it appropriate for side-probing applications on CMM systems equipped with compatible stylus mounting interfaces. It is suited for both production inspection and quality lab environments. The 37.70 mm effective working length provides adequate reach for most shallow-to-medium-depth feature inspection tasks encountered in precision metrology work.

Key Features

• Zirconia probe point for wear resistance and dimensional stability during repeated contact cycles
• Slim 0.60 mm aluminum stem minimizes deflection while keeping stylus mass low
• 45 mm overall length with 37.70 mm effective working length for reach into tight features
• Horizontal mounting orientation suited for side-probing configurations
• Lightweight construction at 0.05 pounds supports accurate low-force probing

Compatibility

Designed as an OEM-style replacement needle stylus for CMM systems accepting standard stylus mounting interfaces. Verify thread type and mounting interface compatibility with your specific CMM head or extension configuration before ordering.

Installation Notes

CMM stylus replacement should be performed by a qualified metrologist or CMM technician. Power down or place the CMM in a safe parked position before handling the probe head to avoid accidental collision damage. Handle the zirconia tip with care during installation, as point chipping can affect measurement accuracy. After installation, run a full qualification routine on the reference sphere to re-establish stylus offset data.
