Features: new high quality Made of high-quality materials for durability CMM stylus CMM stylus for CMM machines CNC machines Straight styli are designed to inspect simple features that can make direct, unobstructed contact with the surface being measured. Tungsten carbide stems provide excellent rigidity, especially for ball and stem diameter styli. Considered the industry standard for stylus nibs. It is of the toughest materials and is suitable for most applications. Long service life and no surface wear due to abrasive materials. The ball head is light-weight, wear-resistant and stable with temperature changes. The ceramic rod is very light yet very strong and offers built-in crash protection. Non-magnetic and non-conductive properties for fine and silicon carbide surfaces, as well as electrical discharge machining (EDM) processes. The probe has good corrosion resistance, wear resistance and light transmission.
