Manufacturers producing high-value components often face challenges when creating internal threads in difficult materials. In industries such as aerospace, where components often carry significant value, a tool failure during threading can result in costly scrap and production delays. To help manufacturers improve reliability in these operations, Sandvik Coromant (Mebane, NC) has launched CoroThread Mill 500, its next-generation solid carbide orbital thread mill for internal threading of blind and through holes.
CoroThread Mill 500 is designed for reliable machining in applications involving deep threads, long overhangs, difficult materials and unstable setups. The product family succeeds the company’s CoroMill® Plura R217 and combines high process security with the flexibility to machine a range of thread forms, sizes and materials using a single tooling concept.
Manufacturers in aerospace, general engineering, automotive, medical and electronics face pressure to increase productivity while reducing tooling costs, scrap and production interruptions. Versatile tooling can help deliver consistent performance, simplify tool inventories and reduce cost per component.
