A EMG Precision 50mm M4 Stylus | 3mm Ceramics Stem | 4mm Ruby Ball Needle | Precision Ruby Ball | EWL 33.5 mm

A stylus for use on coordinate measuring machines (CMM) or systems like machine tool probes. Perfect for use with CNC Touch Probes on machine shop machine centres, lathes and inspection & digitising machines.Straight styli are used to detect easily reachable features on the measured surface. Ruby, as the hardest of all stylus tip materials, is the perfect choice for most applications. Stainless steel is the primary material of choice for high-strength precision styli and extensions If weight can be disregarded. Because of the adhesive material build up, the scanning of aluminium surfaces with ruby tips is not recommended.
