It features a 6 mm ruby ball mounted on an M2 threaded stem with an overall length of 10 mm. Ruby is the standard choice for CMM styli due to its hardness and low wear rate, which supports repeatable contact measurements over high cycle counts. This stylus is installed and qualified by metrology technicians and quality control professionals working in manufacturing, tooling, and inspection environments.\u003c\/p\u003e\n\u003cp\u003eThe Z3500 is suited for short-reach measurement tasks where a compact 10 mm overall length is appropriate. The M2 thread is a common interface size found on a wide range of CMM styli racks, extension bars, and probe modules. It is typically used in applications requiring tight tolerances and consistent stylus qualification on touch-trigger and scanning probes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e6 mm ruby ball for low wear and high repeatability in contact measurement\u003c\/li\u003e\n  \u003cli\u003eM2 thread on both stylus and probe ends for broad interface compatibility\u003c\/li\u003e\n  \u003cli\u003e10 mm overall length suits compact, short-reach CMM applications\u003c\/li\u003e\n  \u003cli\u003eRuby point material resists deformation across high measurement cycle counts\u003c\/li\u003e\n  \u003cli\u003eSingle-piece unit ready for immediate installation and qualification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard addition for CMM systems using M2 threaded stylus interfaces, compatible with touch-trigger and scanning probe configurations that accept M2 stylus stems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eCMM styli are installed by metrology technicians or quality engineers familiar with coordinate measuring machine qualification procedures. The stylus must be properly seated and torqued to the probe or stylus module before running a qualification routine to establish the effective ball diameter and center offset. Avoid touching the ruby ball with bare hands, as oils can affect surface contact during measurement. Always re-qualify the stylus after any removal or reinstallation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBall Diameter\u003c\/strong\u003e: 6 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 10 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStylus Thread Size\u003c\/strong\u003e: M2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProbe Thread Size\u003c\/strong\u003e: M2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStylus Type\u003c\/strong\u003e: Ball\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Material\u003c\/strong\u003e: Ruby\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.38 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: Z3500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51707534180658,"sku":"Z3500","price":89.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/78cedf264527d07633da186c569a5807.jpg?v=1788440832","url":"https:\/\/voomisupply.com\/products\/spi-z3500-cmm-ball-stylus-6mm-ruby-m2-thread","provider":"Voomi Supply","version":"1.0","type":"link"}
