Lead precision Manufacturing precision Generally speaking, the precision indicated defines the lead precision that complies with ISO standards, e.g. G3, G5, etc. (⮑ table 1). Parameters other than lead precision correspond in standard to class 5 of ISO 3408–3:2006. If the application requires special tolerances, ISO class 3 or ISO class 1, please specify these requirements in the inquiry. Lead precision Ewellix offers a variety of high precision solutions to meet the requirements of a growing market. Using equipment at the cutting edge of today’s machining capability allows for the precise...
