Description
The ITP Straight Styli Type A with Ruby Ball offers a precision probing solution built for metrology professionals who need both lightness and rigidity in tight spaces. With a 50 mm overall length and M3 XXT threading, this ruby-ball stylus (model TCM305005050) is designed for stable, repeatable measurements in CMM and automated inspection setups.
- Tip: High-quality ruby ball tip, available in diameters from Ø3.0 mm to Ø12.0 mm, providing wear resistance and accurate contact in every probe pass.
- Stem material: Carbon fibre core delivering exceptional rigidity while keeping weight low for minimal deflection during movement.
- Weight and rigidity: Optimized balance of light mass and stiff construction to enhance dynamic performance and measurement stability.
- Thread: M3 XXT thread for secure, standard-compatible mounting in probe heads and adapters.
- Length: 50 mm overall length tailored for probing tasks in constrained environments.
- Customization: Other dimensions can be requested via the configurator or by email to suit specific measurement needs.
The combination of a carbon fibre stem and a ruby ball tip delivers dependable, repeatable contact with reduced probe load and minimal geometric deviation across scans. The robust ruby ball resists wear, helping extend stylus life in demanding inspection workflows. This stylus is ideal for precision work in metrology labs, electronics manufacturing, and automated inspection lines where consistency and accuracy matter, and it accommodates a range of task-specific tip sizes through straightforward configurability.
