Renishaw’s proven HS20 laser encoder system has been upgraded and is now able to achieve a new maximum speed of 2 m/s for large machine tool applications. Previously the system, which can deliver an accuracy of ±1 µm/m for axis lengths up to 60 m, was limited to 1 m/s but through improvements to the electronic design it has been possible to double the speed performance.
The improved speed allows for the HS20 laser head to be designed into higher velocity applications which are becoming more common in today’s manufacturing industries. The aerospace industry is a key market for large machine tools which require long range but highly accurate encoder systems. With throughput being a key consideration in any machine tool purchase, the improved speed of the HS20 ensures that it will continue to be the preferred long range laser encoder of choice.
The HS20 long range laser system combines the ultimate accuracy of a laser interferometer with the robustness needed for machine tool applications. It offers real-time position feedback with sub-micron resolution through both analogue and digital quadrature.
Renishaw is pleased to unveil the machine that it is developing specifically for production manufacturing. Provisionally named EVO Project, it is the first additive manufacturing system designed and engineered in-house at Renishaw and reflects the company’s 40 years of experience in supplying high quality equipment to demanding global manufacturing businesses.
The new machine, which has a strong emphasis on automation, monitoring technologies and reduced operator interaction, is designed for single material industrial production. Powder handling is almost entirely hands off, whilst powder recirculation, recycling and recovery are all carried out within the inert atmosphere of the system, protecting both the user and the integrity of the material.
Available from Summer 2015
The EVO Project machine incorporates a high power 500 W laser which will aid productivity whilst still maintaining precision and surface finish. It also boasts a class leading high capacity filtration system, a large 19” HMI user interface and intelligent workflow to further reduce the need for operator interaction. The new machine, which is planned to be available in the second-half of 2015, is designed to complement and not replace the current Renishaw AM250 system which is better suited for flexible manufacturing and research applications where changes between materials are a requirement. The AM250 has an interchangeable hopper system which allows various materials to be used on the same machine.
