CMM Styli - Probe Tips

Straight Styli is the simplest form of stylus,highly spherical industrial ruby balls and a choice of stem material.

Ruby is an extremely hard material and high anti-wear,light weight,keeping tip mass to a minimum, which avoids unwanted probe triggers caused by machine motion or vibration.

Ruby ball is mounted on stems made from a range of materials - stainless steel, tungsten carbide, ceramic, and a specialized carbon fiber material, which is suitable for most inspection applications.

The size of the ball and the EWL of the stylus chosen are dictated by the size of the feature to be inspected. However, keeping the stylus ball as large as possible and the stem as short as possible will ensure maximum ball/stem clearance, whilst providing a greater yet still rigid EWL. Using larger ruby balls also reduces the effect of the surface finish of the component being inspected.

Ruby Ball Material

Synthetic ruby is 99% pure aluminium oxide which is grown into crystals,at 2000 ?∞C using the Verneuil process,one of the hardest material ever known,have great compressive strength and a high resistance to mechanical corrosion.However there are only two applications where ruby balls  are not recommended. The first is for heavy duty scanning applications on aluminium. Because the materials attract, a phenomenon known as ??òadhesive wear can occur,A better ball material for such applications is silicon nitride. The second is in heavy duty scanning applications on cast iron. For such applications, Zirconia balls are recommended.

Stainless Steel  and tungsten Stem Material

Stainless steel stem are used widely for styli with ball/tip diameters of 2 mm or greater and with lengths up to 30 mm. Within this range, one-piece steel stems offer the optimum stiffness to weight ratio, giving adequate ball/stem clearance without compromising stiffness with a joint between the stem and threaded body. We also offer tungsten stem for your special requirement.


To determine your thread size,measure the diameter of your current Styli thread or check your probe model number.
