Features: 100% brand new high quality Made of high-quality materials for durability CMM styli for CMM machines CMM styli for CNC machines Straight styli are designed to inspect simple features that make direct, unobstructed contact with the surface being measured. Stainless steel stems provide excellent rigidity, especially for ball and stem diameter styli. Ceramic ball tips are considered the industry standard for stylus tips. It is one 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 stainless steel bars are very light yet very strong and offer built-in crash protection. Non-magnetic and non-conductive properties for fine and silicon carbide surfaces and electrical discharge machining (EDM) processes. The probe has good corrosion resistance, wear resistance and light transmission. 25mm diameter ceramic balls mounted on steel posts. The threaded post has an M10 thread for mounting on a cmm table. Product parameters: Ceramic ball diameter: 25mm Thread: M10 Length:157mm Package list: 1 * CMM stylus Note: 1.The real color of the item may be slightly different from the pictures shown on website caused by many factors such as brightness of your monitor and light brightness. 2.Please allow slight manual measurement deviation for the data.
