Efficient coolant delivery plays a key role in internal grooving of heat-resistant super alloys, where proper cooling significantly affects both tool life and process stability. In this case, we focused on internal grooving of a Ti6Al4V forging<\/strong>, a component of an aircraft engine.<\/p>\n\n\n\n

The customer used a SL70-SRDCR-50-12<\/strong> tool with an RCMT 1204M0 \u2013 MK<\/strong> insert, with grooving performed using a trochoidal strategy. The goal was to minimize any process modifications and not to interfere with the approved technology.<\/p>\n\n\n\n

Solution: Innovative flank-face cooling<\/h2>\n\n\n\n

We designed a modification of the flank section of the tool holder<\/strong> to provide more efficient coolant delivery along the entire active cutting edge. Based on the original design, we produced a new tool body<\/strong> that is fully compatible<\/strong> with the original tool, except for the newly integrated flank element for coolant supply<\/strong>.<\/p>\n\n\n\n

The flank element was produced by 3D printing from tool steel<\/strong> and attached to the tool body with a screw. Thanks to additive manufacturing<\/strong>, it was possible to optimize the orientation of the nozzles<\/strong>, which precisely deliver coolant along the entire active length of the circular cutting edge.<\/p>\n\n\n\n

Results<\/h2>\n\n\n\n

\u2705 3.5\u00d7 longer tool life<\/strong>
\u2705 More consistent and predictable wear<\/strong>
\u2705 Enhanced process reliability through efficient cooling<\/strong><\/p>\n\n\n\n

The flank coolant supply usually brings significant benefits when machining titanium alloys, which was also confirmed in this application. With only minimal modification to the tool body, a more stable process, reduced tooling costs, and higher production efficiency<\/strong> were achieved.<\/p>\n\n\n\n
