NC4 non-contact tool setters provide high-precision, high-speed tool measurement and broken tool detection, allowing process control on all sizes and types of machine tools. During machining processes, dimensional accuracy is dependant upon several variables, including tool size deviation, tool run-out and tool breakage. Renishaw’s NC4 systems allow users to control these variables, enabling measurement of a wide variety of tools at production feeds and speeds, while minimising the risk of excessive tool wear or tool breakage – an important consideration for small and fragile tools. NC4+ Blue fixed systems Featuring industry-first blue laser technology and improved optics, Renishaw’s NC4+ Blue systems are available with an operating gap of up to 240 mm and deliver a step change in tool measurement accuracy, proven to industrial standards.
