Description
The ITP Straight Stylus with Ruby Ball is a precision probing accessory designed for metrology setups that clamp star styli. It delivers a reliable Z-direction probing option with a height-matched profile for consistent measurements.
- Thread: M3 XXT thread with an extended shank to align with the height of the star stylus
- Overall length: 20 mm
- Probing elements: Ruby ball (with silicon nitride as an alternative option) available for the probing tip
- Body design: Durable metal construction built for secure clamping and repeatable positioning
- Z-direction probing: Adds a dedicated probing option in the Z axis for enhanced measurement coverage
Using this straight stylus simplifies star-stylus workflows by providing a stable, repeatable contact point at the correct height. The extended thread ensures proper alignment with the star stylus, reducing setup time and minimizing positional errors during probing. Its compact form and robust build make it a practical addition to any CMM or automated probing rig, offering flexibility with either ruby ball or silicon nitride probing elements for diverse material and feature types.
