Renishaw To Demonstrate Products At Westec 2010

At Westec 2010, Renishaw will display products that increase machine-tool automation and process control, as well as a wireless device for assessing the performance of machines before metal cutting. The company will introduce new touch-probe systems that use its frequency-hopping spread spectrum (FHSS) probe signal radio-transmission technology to allow automated job set-up and in-process measurement on all sizes of CNC machine tools.

The ultra-compact RMP40 touch probe is suited to multi-axis and mill-turn applications, while its variant, the RLP40 touch probe, is designed for more hostile turning environments. Also on show at Westec will be the successor to Renishaw's QC10 ballbar system, which has been adopted worldwide for the assessment of machine-tool positioning and servo-control performance.

The QC20-W ballbar is a new design featuring a Renishaw-developed linear sensor and Bluetooth wireless technology, which also allows testing in three orthogonal planes through a single reference point. A single, simple hardware set-up means quicker testing and the ability to produce a representative volumetric measurement of positioning accuracy.

Renishaw's Resolute absolute optical-encoder system gives a resolution of just 1nm at 100m per second for linear encoder and angle-encoder applications, yet still offers excellent dirt immunity. Absolute position is acquired immediately at system switch-on, so the exact orientation of axis and motor commutation angle are known without the need for a reference (datum) return. Large set-up tolerances enable easy installation and reliability, while low jitter and SDE (sub-divisional error) meet the demands of high precision stages.

Visitors to Westec will also be able to see additions to the Toniic range of incremental optical linear and rotary encoders, including 1 and 2nm resolutions, a dual-output encoder interface and compatibility with Renishaw's Dual Signal Interface (DSi) for high accuracy angle encoding.
