Automated tool production on show

Informative technical presentations on Walter and Ewag tool grinding, erosion and laser processes – available in the UK from Walter Ewag UK – were among the array of technology treats displayed and discussed at the United Grinding Group’s three-day Grinding Symposium 2019 in Thun, Switzerland, where more than 1500 visitors attended.

While Ewag focused on the use of lasers in online tool manufacturing, Walter highlighted both ‘high-end’ and PCD tool production. The potential benefits of Ewag’s Laser Line Ultra machine in the production of ultra-hard tools (solid carbide and PCD) for one customer were revealed as part of a novel Internet-based demonstration. After witnessing Ewag’s prototype demonstration at GrindTec 2018, when 200 tools were produced by the Laser Line Ultra, the customer established a cell around the machine where eight pallets accommodate a total of 1800 tools. Orders and production run autonomously with no operator involvement, round the clock if required.
The production of fir-tree milling cutters (HSS/carbide) for aerospace blade machining was outlined by Walter, using a cutter of 25 mm diameter and 40 mm long – and demanding a profile tolerance of ±2 µm – as an example. This demonstration showed the process integrity of the combined attributes of a Helitronic Power 400 tool grinding machine and a Helicheck 3D measuring machine, used for scanning a tool to create a 3D master model.
Walter also presented the effectiveness of integrating its ‘two-in-one’ Helicheck Power Diamond 400 grinding and erosion machine with the automated Helicheck Plus inspection machine for the production of PCD-tipped solid-carbide tools.
