FORTiS™ downloads

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.

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.

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.

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.

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.

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.
