BIG Kaiser, a ‘global leader’ in premium high-precision tooling systems and solutions for the metal-working industries, has introduced the latest version of its EWA fine-boring tool.

Available in the UK from Tamworth-based Industrial Tooling Corporation Ltd (www.itc-ltd.co.uk), the new ‘intelligent and fully automatic’ fine-boring tool does not require manual intervention.

It achieves fast, accurate boring and the process does not need to be stopped to make measurements or manual adjustments to the tool — not only saving time and instilling confidence in the operator but also minimising scrap that can result from manual adjustment errors.

The new EWA features a sealed motor, while the clamping system provides high levels of stability and repeatability — even at cutting speeds above 200m/min.

The EWA can be used with BIG Kaiser’s extensive range of standard accessories; and to maximise operational flexibility, it offers an adjustment range of 22mm.

Furthermore, the system has an integrated accelerometer that measures vibration during the cutting process; in the event of excessive vibrations, the EWA alerts the machine tool to automatically adjust its cutting parameters.

The new EWA will initially come in two versions.

The EWA Peripheric will cover diameters from 68 to 90mm, while the EWA Centric will incorporate a central boring bar (with internal coolant) for smaller diameters.

Other models for different adjustment ranges are currently in the design phase and will be introduced in the near future.

A recent demonstration undertaken on a Fanuc CNC machine saw the entire boring cycle performed automatically.

This included the initial bore machining, subsequent automatic measuring and then the automatic adjustment process to complete the final precision bore.
