Blue laser technology: setting the standard in on-machine tool measurement

5 March 2020

Global engineering technologies company, Renishaw, will demonstrate its latest non-contact tool setting solution at MACH 2020, from 20th - 24th April, following its debut launch at EMO Hannover 2019. The new NC4+ Blue system will be one of many smart factory process control solutions demonstrated by Renishaw, which are proven to help machine shops across many industries transform their production capabilities.

Building on the success of the enhanced NC4 range of tool setters launched at EMO Hannover 2017, the NC4+ Blue is Renishaw's latest evolution of the non-contact tool setter, delivering a step-change in tool measurement accuracy, with tool-to-tool performance proven to industry standards.

Improved component accuracy with reduced cycle time

Featuring industry-first, blue laser technology (patent pending) and improved optics, Renishaw's NC4+ Blue systems deliver significant improvements in tool measurement accuracy, ensuring components can be machined more accurately and efficiently.

Compared to red laser sources found in conventional non-contact tool setters, blue laser technology has a shorter wavelength, resulting in improved diffraction effects and optimised laser beam geometry. This enables the measurement of very small tools, whilst minimising tool-to-tool measurement errors – a critical consideration when machining with a wide range of cutting tools.

NC4+ Blue systems also use Renishaw's latest non-contact tool setting software packages, which include a new dual measurement mode with auto optimisation technology. Combined, these features ensure fast and reliable tool measurement, even in wet conditions – saving users time and money.

Simplified programming and reporting – Industry 4.0 ready

NC4+ Blue support is now embedded into Renishaw's extensive range of graphical user interfaces, including on-machine and mobile apps such as Renishaw Set and Inspect and GoProbe. These consistent, easy-to-use programming platforms are perfect for users who are new to probing or have little machine code knowledge, whilst still offering operational benefits to more experienced users.

Renishaw technologies provide the data that enables intelligent decision-making for Industry 4.0. On-machine tool measurement allows manufacturers to automate and optimise their processes and minimise quality problems and CNC machine stoppages. With the latest version of Renishaw's on-machine Reporter app, users can now view historical tool data captured by the NC4+ Blue and export the results for use in their chosen software and control systems.
