/ TOOLS T he new hole enlarging tool has been designed for use on a wide range of materials. It is ideal for milling and turning processes. It has been designed for working ADVANCED TECHNOLOGY FOR ENLARGING HOLES: SYNTHESIS OF PROCESSES, COST REDUCTION in all segments of the industry, including aerospace, wind, hydraulic, railway, automotive, moulds and die-casting, mechanical engineering, among others. Also ideal for machining large pieces. • Tool with internal cooling • Vc 80-150 m for stainless steel and steels treated with 1,200 Nn resistance. • Vc 40-60 m for inconel. JUNCAL DÍAZ, EUSKRON The technology of the new drill bit (ref. NS3992.91) developed by Euskron guarantees increased productivity thanks to synthesising several processes into one. It is a tool capable of removing all excess material in a single run, without generating vibrations. 60 / • Vc 60-82 m for titanium. • Vc 150-250 m for other materials (F114, ST52, C45) • Fn feedrate: 0.18 - 0.30 mm. • Depth of ae cut: 20-25 mm / Special up to 60 mm Among the advantages of this new tool, it is worth highlighting the reduction of working time thanks to it performing the roughing in a single run, which allows for reducing the machining time in comparison to the interpolation technique. Also, it guarantees higher chips removal speed: The technique developed in this tool allows for removing a larger amount of chips per minute, reducing the machining time by 5 to 10 times. It also guarantees an optimal surface quality and high process safety: The tool moves in circular and linear movements, without the need to move the large pieces to be machined, making this safer than tradi- tional procedures involved in chips removal via inter- Technical specifications polation. Lastly, it guarantees a longer useful life for the tool thanks to its technology leading to the machine suffering less wear. • Plate recommendation • For blind hole: CCMT 09/12 • For through hole: SCMT 09/12. /
