Case studies and application notes

Xtreme CNC milling machine (RM Technologies)
Ronchini Milling Technologies chooses Renishaw metrology products to enhance cutting-edge milling machines
RM Technologies has significantly improved the precision, reduced the set-up times, and enhanced the reliability of its milling machines by integrating Renishaw's advanced products. The products include the FORTiS™ enclosed position encoder, ADTa-100 diagnostic tool, RCS P-series probing system, and the QC20 ballbar.
RAM Service - retrofitted Studer S30
R.A.M. Service retrofits a classic grinding machine with FORTiS™ linear encoder scales
R.A.M. Service, a specialist in retrofits and technical services, successfully upgraded an old Studer S30 grinding machine for Euro Tecno Tool by installing Renishaw's FORTiS linear encoder scales. These provide micron-level precision and easy installation, significantly improving the Studer machine's accuracy and ability to grind complex shapes.
Ballscrew in machine tool
The effect of heat on ballscrew accuracy in a CNC machine tool
This application note discusses the impact of heat build-up in ballscrews on the accuracy of CNC machine tools. It uses test data to explain that while linear axis control with a semi-closed servo loop (using rotary encoders and ballscrews) can achieve high accuracy, thermal expansion of the ballscrew can cause significant error. Linear scales offer a crucial advantage in environments where heat build-up is a concern.
Roll-up banner for Anderson case study
Enhancing micro-milling precision with FORTiS-N™ enclosed encoders
Anderson Europe chose FORTiS-N enclosed encoders to build state-of-the-art precision micro-milling machines. These linear encoders provide high accuracy, robustness, sealing against contamination and vibration resistance — ensuring outstanding performance in micro-milling applications.
Car chassis
FORTiS-S™ sealed linear encoders with lengths up to 4240 mm
Combining high-accuracy position measurement with robustness and reliability, the FORTiS™ encoder series is designed to provide a solid foundation for CNC machining processes, with even longer measuring lengths, helping to bring these advantages to larger machines such as giga presses, vertical turning lathes and outsized CNC machine tools.
Mr Ranganatha, Director of Tool Grinding Technologies Inc.
FORTiS™ enclosed encoder enhances grinding precision and performance
After testing and evaluation, TGT selected Renishaw’s FORTiS™ enclosed encoders for its latest series of tool grinding machines. The ease of installation and other leading-edge features of the FORTiS encoder system enable TGT to optimise its machines’ performance.
Gary Pearson
Renishaw’s enclosed encoders used in new hybrid additive and subtractive machine tool
To help Effective CNC design and build an 'all-in-one' machine that can perform both additive and subtractive machining operations in tandem, Renishaw provided support with its technical teams specialising in optical position encoders, tool setters and machine tool probes.
FORTiS enclosed encoders air purge
Reducing air purge usage with FORTiS™ encoders, achieving energy saving up to 91%
Machine users adopting a smart approach to air purge with FORTiS absolute enclosed encoders can significantly reduce their attributable CO2e emissions, and lower electricity costs. FORTiS' unique DuraSeal™ lip seals allow many users to employ a “low flow” air purge philosophy to provide all the reliability benefits of air purge but with reduced compressed air consumption.

Vibration on FORTiS™ enclosed encoders
Tuned mass dampers help FORTiS™ encoders achieve class-leading vibration resistance
FORTiS encoders are the only enclosed encoder on the market to feature integrated tuned mass dampers (TMDs) that deliver outstanding vibration resistance. The FORTiS encoder TMDs improve positional stability, especially at the encoder's resonant frequency, and enable continuous operation in high vibration environments.
