ITP Straight Styli Type A with a silicon nitride ball delivers precise, rigid probing in tight metrology tasks. Designed for CMM operators and quality labs, it offers dependable contact and minimal deflection for accurate measurements.
- Thread: M5 thread for secure attachment to CMM probes and holders.
- Overall length: 25 mm to provide a compact, low-profile probing solution.
- Ball material: Silicon nitride ball, chosen for hardness and wear resistance on challenging surfaces.
- Stem material: Carbon fiber stem delivering high rigidity with very low weight, ideal for long-reach styli.
- Performance: Low weight and extreme rigidity reduce deflection and improve measurement stability during scanning.
- Additional options: Other dimensions can be requested via the configurator or by e-mail.
This combination is particularly well-suited for scanning untreated aluminum workpieces, where surface characteristics can affect contact and data quality. The carbon fiber stem minimizes inertia for smoother, more repeatable measurements, while the silicon nitride ball provides durable, consistent contact across multiple passes. Ideal for professional metrology setups, QC labs, and precision machining environments that demand reliable, repeatable results from a compact stylus.
