A CMM stylus is the part of a coordinate measuring machine probe that touches the workpiece, and the ball at its tip decides how accurately features can be reached and measured. Ruby balls are common because ruby is very hard and wears slowly. Styli are used in quality labs, inspection rooms and tool rooms for checking holes, slots, faces and contours on machined parts.

Choose the ball diameter and stylus length for the feature: use the largest ball that fits the feature and the shortest stylus that reaches it, because a long, thin stylus bends more and lowers accuracy. Small balls, down to 0.5 mm, reach small holes and fine detail, while larger balls average out surface finish. Match the stylus thread to your probe or extension before ordering, and use the part number to find the right one. After changing a stylus, qualify it on the reference sphere before measuring, and handle the ball with care to avoid chips.

Questions

How do I choose the right CMM stylus?

Match the thread to your probe, then choose the ball size and length for the feature. Use the part number to find the exact stylus.

Why use a ruby ball stylus?

Ruby is very hard and wears slowly, so the ball keeps its shape over many measurements.

Does a longer stylus reduce accuracy?

A longer stylus can bend more during contact. Use the shortest stylus that reaches the feature.

Do prices include GST?

Yes. Prices include GST and every order gets a GST invoice.
