Automatic Boring Available from ITC

BIG KAISER, a global leader in premium high-precision tooling systems and solutions for the metalworking industries, has now introduced the latest version of its EWA fine boring tool. Available in the UK from Industrial Tooling Corporation (ITC), the new intelligent and fully automatic fine boring tool received its exhibition premiere at the EMO 2019 show in Hannover.

Being a fully automatic fine boring tool, the EWA does not require human intervention. It achieves fast, accurate boring and this is because the process does not need to be stopped to make measurements or manual adjustments to the fine boring tool. As well as saving time, this instils confidence in the operator, and it minimises costly scrap that can result from manual adjustment errors.

The new EWA features a powerful motor for robust and reliability operation and it is sealed against dirt and water in accordance with IP69 regulation. The clamping system provides additional stability and repeatability to deliver consistently high levels of reliability and precision at cutting speeds above 200m/min.

The exciting new EWA from ITC, can be used with BIG KAISER’s extensive standard range of accessories, making it easy to add to an existing system. To maximize flexibility, it offers an adjustment range of 22mm, which is substantially larger than similar solutions available in the market. Furthermore, the system has an integrated accelerometer that measures vibration during the cutting process and in the event of excessive vibrations, the EWA alerts the machine tool to automatically adjust its cutting parameters.

Jose Fenollosa, Head of Research & Development at BIG KAISER, said: “The EWA is far ahead of the rest in its level of automation and sophistication, and this gives our customers real benefits in terms of time and money saved. It also makes it ideal for Industry 4.0 applications. We are talking to potential customers now, including some of the leading machine tool manufacturers. The final EWA product will be available in 2020.”

The new EWA will initially come in two versions. The EWA peripheric will cover diameters from 68mm to 90mm and the EWA centric, which 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 destined to be introduced in the near future. The demonstration at the EMO exhibition was undertaken on a FANUC CNC machine whereby the entire boring cycle was performed automatically. This included the initial bore machining, subsequent measuring and then the adjustment process to complete the final precision bore. The EWA features wireless connectivity to BIG KAISER’s user-friendly smartphone and tablet app for easier tool monitoring and configuration. It can also automatically communicate with a pre-setter, so diameter measurements can be transferred without operator intervention.
