Renishaw at EMO

Renishaw will highlight process control solutions to support lean manufacturing, a range of additive manufacturing technologies, and encoder systems. For visitors sourcing off-line measurement systems, Equator is a radical new alternative to traditional dedicated gauging. Its patented low-cost design is capable of high-speed comparative gauging for inspection of high-volume manufactured parts. Hall 5, Stand D54It has been developed and proven on the shop-floor, working closely with automotive, aerospace and medical gauging users. The result is a lightweight, fast and highly repeatable gauge that operators can use with ‘push-button’ simplicity. Equator can switch between parts in seconds, perfect for flexible manufacturing processes or accepting parts from multiple machines.

Following its purchase of MTT Technologies, Renishaw will use EMO to highlight its new range of additive manufacturing technologies. On show will be the SLM250 Selective Laser Melting (SLM) machine, which uses a pioneering, additive manufacturing process capable of producing fully dense metal parts direct from 3D CAD, using a high-powered fiber laser. Parts are built from a range of fine metal powders that are fully melted in a tightly controlled atmosphere, in layer thicknesses ranging from 20 to 100µm.

In addition to the conveniences of wireless operation, the QC20-W telescoping ballbar is the first calibration tool to allow 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. Meanwhile AxiSet Check-Up extends Renishaw’s range of machine tool testing and calibration systems, with a cost-effective solution for checking the alignment and positioning performance of rotary axes. In just a few minutes, users of 5-axis machining centres and multi-tasking mill-turn machines can now identify and report on poor machine alignments and geometry that can cause extended process setting times, as well as non-conforming parts.

Visitors looking to improve measurement speeds on CMMs will see demonstrations of the PH20 5-axis touch-trigger system, which increases touch-trigger CMM throughput up to three times, using fast, infinite, rotary positioning and ‘head touch’ capability for high-speed point capture with minimal CMM movement. The PH20 uses two-axes of head motion to minimise CMM movement and associated dynamic errors at higher measurement speeds. Its innovative ‘inferred calibration’ feature determines head orientation and probe position in a single operation, eliminating the need for calibration at each orientation.

The company will also present details of its certified CMM retrofits which upgrade existing machines to state-of-the-art capabilities - including REVO 5-axis ultra-high-speed scanning. The comprehensive retrofit program applies to all brands of machines. And for visitors considering inspecting parts on their machine tools, the new OMV Pro software includes more advanced CMM-type capabilities with an extended range of geometric dimensioning and tolerancing (GD) functionality, plus the ability to work with multiple alignments in a single program, an advantage in working with multi-axis machine tools. The software includes simulation capability, an intuitive graphical interface and crystal-clear reporting format that make it accessible to shop-floor staff.

Renishaw will also highlight its latest encoder products, including RESOLUTE, the world's first true absolute encoder which is capable of 27 bit resolution at 36,000revs/min. The fine-pitch system offers excellent dirt immunity, while delivering market-leading resolution of just 1 nanometer at up to 100m/s, for both linear and angle encoding applications. TONiC incremental optical encoders provide the accuracy of fragile fine-pitch encoders, but in a rugged, simple-to-install package. Advanced optical design and innovative electronics are featured in a compact readhead for design/application flexibility and installation even on micro-manufacturing systems. New additions to the TONiC range of linear and rotary encoders include 1nm and 2nm resolutions, a dual output encoder interface, and compatibility with Renishaw’s Dual Signal Interface (DSi) for high accuracy angle encoding.
