Latest encoders and probes to feature in
Stockholm

Renishaw is highlighting its new range of encoder solutions at Scanautomatic, Sweden's only industrial automation and process automation exhibition, in Stockholm from 18th to 21st October 2005.

Renishaw is highlighting its new range of encoder solutions at Scanautomatic, Sweden's only industrial automation and process automation exhibition, being held in Stockholm from 18th to 21st October 2005 Renishaw will be on stand C21:40

Also actively demonstrated on a Fanuc Robodrill machine tool will be a range of Renishaw's touch probe systems for part setup and laser tool setters for fast noncontact tool setting and broken tool detection.

The latest probe systems for co-ordinate measuring machines (CMMs) will also be shown, plus Renishaw's QC10 ballbar system for machine tool performance analysis and new QuickView motion analysis software demonstrated in conjunction with Renishaw's ML10 laser measurement system.

The focus for position feedback systems will be a new range of high-performance linear and ultra-high-vacuum encoders, an ultrastable Invar scale, high resolution laser interferometer encoders, plus demonstrations of evolutionary improvements in speed, resolution and reliability to Renishaw's standard optical encoder lines of industrialised RG2 and RG4 linear encoders.

The technology extensions further consolidate Renishaw's position as a global leader in micron, nanometre and picometer position feedback systems for everything from lab and medical instruments and semiconductor manufacturing equipment, to machine tools, metrology systems, and massive aerospace assembly machines.

At Scanautomatic, Renishaw will exhibit three different advanced technologies for precision positioning - optical, magnetic and laser interferometer - each providing special solutions to difficult applications.

All feature exceptional compactness and installation ease, providing tremendous design flexibility and application range.

Proven in thousands of installations across the spectrum of precision machines and instruments, Renishaw's optical encoders were created to bring high precision, speed and reliability to demanding environments and tough industrial applications.

Innovative metal scales avoid the fragility of glass encoders, and unique noncontact readheads and filtering optics avoid the bulkiness, hysteresis and wear of traditional industrial encoders.

A new Signum family of rotary and linear encoders applies that same formula of ruggedness and precision to deliver levels of performance previously possible only from fine-pitch systems too delicate for many industrial roles.

Meeting demand for reliable, low-cost, high-speed rotary encoders, Renishaw's miniature magnetic rotary encoders provide class-leading performance along with "tough-guy" ruggedness and durability.

Available in component, modular and packaged shaft-style models, RM family magnetic encoders offer up to 4096-count positioning resolution, accuracy to 0.4um, and operating speeds to over 9000rev/min.

noncontact magnetic design eliminates seals, bearings and moving parts for lifetime reliability.

Standard models provide excellent shock and vibration resistance, while optional sealed models allow application in harsh environments and even immersion.

Low cost, compact size and design simplicity enable use in a wide range of industries.

Unique RL fibre-optic laser interferometer encoders deliver interferometer-based nanometre positioning accuracy from a remote laser source - even to two axes.

New detector head choices (six in all) allow careful matching to a wide range of application requirements, including capability for picometre-level resolutions.

fibre-optic beam delivery greatly reduces optical path complexity, saves space on miniature machines, and keeps heat of the laser from affecting measurement axes.

Simple "bolt-down/dial-in" laser alignment enables ease of installation comparable to traditional tape- or glass-based encoders.

Applications include x-y stages, fibre-optic alignment machines, glass grinding machines, photomask machines, and other precision motion systems.

An optional real-time compensation system enables positional accuracy of 1ppm (1um/m) in a wide range of environmental conditions.

Scanautomatic is being held at the Swedish Exhibition Centre, and runs alongside the Scandinavian Technical Fair (with storage and transportation).

The organiser is claiming that this will therefore be Scandinavia's largest ever industrial exhibition. Request free introductory details about products from Renishaw ...
