Cylinder Ruby

The term "cylinder ruby" primarily refers to high-precision industrial components used in metrology (CMM probes) and laser technology, rather than decorative gemstones.

Core Product Insights

The most common application for "cylinder ruby" is as a styli or probe tip for Coordinate Measuring Machines (CMM). These are typically synthetic rubies ($Al_2O_3$) grown via the flame fusion process to ensure maximum hardness (Mohs 9) and thermal stability Itpstyli.

• CMM Styli: Designed with cylindrical or spherical-cylinder tips to measure thin workpieces like sheet metal where a ball probe might fail to maintain contact HelmelZeiss.
• Laser Rods: Industrial synthetic ruby rods (often $8 \times 165$mm or similar) serve as gain media in laser machines for welding or medical applications Alibaba.
• Jewelry Rough: Cylindrical synthetic corundum is also used as a raw material for faceting into jewelry Alibaba.
