Renishaw will showcase Renscan5 at TCT
Renishaw will demonstrate its Renscan5 5-axis coordinate measuring machine (CMM) measurement technology, which includes the award-winning REVO measuring head, at the TCT exhibition.
PC-based probing software use extended
Enhanced PC-based probing software is now available to thousands more machine tool users, said Renishaw, which has upgraded its Productivity+ Active Editor Pro software.
Highest accuracy The RESR, a one-piece stainless steel ring with axial graduations marked directly onto the periphery, is read by Renishaw's RGH20 readhead.
The system utilises filtering optics, which provide a high tolerance to dirt, scratches and greasy fingerprints that can cause other encoder systems to miscount.
The RESR boasts impressive performance with resolution to 0.01 arc second, suiting the most demanding precision applications.

Laser calibration offers precision, portability
Renishaw's lean-design XL-80 laser calibration system measures at 4m/s, raises environmentally-corrected accuracy to +/-0.5 ppm, warms up faster, weighs less and transports easier.
Wide range Available in a wide range of sizes (52 mm - 413 mm), all of which feature an internal diameter approximately 20 mm less than the outer diameter; the rings have an ultra low section and a large internal diameter.
Consequently, the low profile RESR is easy to design into most installations, but more importantly its low mass and low inertia design, will not compromise system accuracy or performance.
Moreover, the patented taper mount can accommodate most installation tolerances - including those of the parent mounting surfaces - and can correct run-out or ovality by easy and robust fine adjustments.
Analogue or digital outputs Offering high speed, non-contact optical performance, the RESR can be combined with Renishaw's RGH20, RGH34 or RGH40 readheads to offer industry standard analogue or digital outputs.
A repeatable reference mark is available to provide a home (datum) position, while the RGH40 readhead with filtering optics offers dual limit sensors.
Versatility Many applications rely on precision rotary motion; rotary format computer-to-plate (CTP) printing systems, pick and place, form measurement, rotary tables, machine tool A, B and C axes, wafer handling and goniometers, all use some form of rotary encoder.
Every application is different, yet they all benefit from a number of essential features offered by the RESR; high accuracy, high resolution, repeatability, low mass, easy installation, and reliability In 1965 the Company instituted the Achievement Award to recognise outstanding contributions to the British scientific instrument industry.
