Exhibition roadshow moves on to Cairo

Renishaw is continuing its hectic Autumn schedule of exhibitions with a visit to Egypt's Mactech exhibition being held at the Cairo Fair Ground from 17th to 20th November 2005.

Renishaw is continuing its hectic Autumn schedule of exhibitions with a visit to Egypt's Mactech exhibition being held at the Cairo Fair Ground from 17th to 20th November 2005 Described as the international exhibition for machine tools, industrial tools, welding and cutting equipment, Mactech is Egypt's leading event for the engineering industry

It is being targeted by Renishaw as an opportunity to introduce Egyptian companies to a wide range of products seen at the recent EMO Hanover exhibition.

Renishaw will exhibit in Hall 6, stand number A29.

The main focus at Mactech will be Renishaw's new products for CNC machine tools, including OMP60, a compact touch probe for machining centres and mill-turn machines and the new TRS1 tool recognition system for high-speed tool breakage detection.

Other products to be shown include Renishaw's QC10 ballbar system for the fast analysis of machine tool performance, the ML10 laser interferometer measurement system for machine calibration, and a new angle encoder for precision position feedback on rotary axes.

Renishaw's new OMP60 touch probe is the first of a new generation of optical transmission products designed for compatibility with all current Renishaw optical receivers and next generation optical systems.

It brings the benefits of probing to a wide range of machine tools, offering users set-up time reductions of up to 90%, reduced scrap, reduced fixture costs, and improved process control.

For visitors to Mactech sourcing a device for tool breakage detection, Renishaw's new TRS1 system projects a beam of laser light at a tool and monitors the scattered light that is reflected to determine if the tool has been broken.

This new tool recognition technology distinguishes between the tool and coolant or swarf, whilst it is also fast and reliable under real machining conditions.

More reliable than conventional noncontact systems, the TRS1 comprises a single unit containing the laser source and detection electronics, enabling it to be mounted outside of the working envelope, safe from collision and saving valuable space on the table.

Since its launch some 10 years ago, the Renishaw QC10 ballbar has established itself as an industry standard system for rapid machine tool performance analysis and diagnosis.

Mactech visitors will learn that the QC10 ballbar test typically takes about 15 minutes.

The ballbar attaches magnetically between the machining centre's spindle and table, and tracks machine movement to +/-0.5um.

A simple CNC circular program is run which allows the ballbar software to calculate machine circularity error, servo gain mismatch, vibration, stick-slip errors, backlash, repeatability and scale mismatch, as well as machine geometry.

Renishaw's ML10 laser interferometer measurement system is used by some of the largest OEMs and end users in industries such as metal cutting, semiconductor processing, flat panel display production and biotechnology.

The ML10's unique properties ensure that the system provides a linear position reading resolution of just 1.24nm, a range of up to 40m and accuracy better than 1ppm.

This combination of resolution, accuracy and range makes the laser interferometer an ideal tool for characterising the performance of motion systems, both large and small.

For visitors to Mactech requiring precision motion system analysis, QuickView is a new software package from Renishaw designed to make the ML10 laser an even more flexible and powerful analysis tool.

For years, electronic engineers have relied on oscilloscopes to study high-speed variations in voltage or current.

Now, QuickView software provides mechanical engineers with a similar capability, allowing them to study minute variations in linear or angular displacement, velocity or acceleration.

With a simple graphical interface QuickView allows very flexible operation, avoiding the need for predefined measurement targets and sequences - just point and measure, ideal for ad-hoc system investigations.

Offering high speed, noncontact performance, combined with advanced features including the In-Trac auto-phase optical reference mark, Renishaw's new Signum range of encoders, includes the high accuracy RESM optical angle encoder.

The RESM is a one-piece stainless steel ring with 20um graduations marked axially on the periphery, offering accuracy to +/-0.5arc-sec and resolution and repeatability to 0.02arc-sec.

It is highly suitable for visitors to Mactech involved with precision applications, including machine tool rotary axes.

The In-Trac reference mark is repeatable in both directions at speeds over 3600rev/min (52mm diameter) and up to 85C.

The Mactech exhibition includes a wide range of metalworking technology including machine tools with manual and automatic controls, precision cutting tools, measuring technology, machines and devices for plastic forming, EDM, CAD/CAM systems and coolants.
