Product Description
Renishaw M4 2 mm Zirconia Ball Stylus - Stainless Steel Stem (L 19 mm EWL 9.2 mm)
Straight Styli
The simplest form of stylus, incorporating highly spherical industrial ruby balls and a choice of stem material.
Ruby is an extremely hard material and hence stylus wear is minimized. It is also of low density, keeping tip mass to a minimum, which avoids unwanted probe triggers caused by machine motion or vibration.
Mounted on stems made from a range of materials - stainless steel, tungsten carbide, ceramic, and a specialized carbon fiber material, "Renishaw GF" - these simple ruby ball styli are 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.
Zirconia Ball Material
Zirconia is a particularly tough ceramic material with hardness and wear characteristics approaching those of ruby. Its surface properties make it an ideal material for aggressive scanning applications on cast iron components.Stainless Steel Stem Material
Stylus stems manufactured from stainless steel 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.
