Nikko Tools MicroNega technology integrates with micro double-sided negative inserts usable as an alternative to positive inserts for external and internal turning operations, from finishing to medium machining.<\/p>\n<p>The range of MicroNega inserts comprises two types of chipbreakers especially designed for small boring operations while delivering the best performances:<\/p>\n<ul>\n<li><strong>directly pressed (GM),<\/strong>\u00a0 for <strong>general machining<\/strong> operations, suitable from light to medium cutting with perfect chip control.<\/li>\n<li><strong>precision ground (SS), <\/strong>for <strong>precision machining.<\/strong> This chipbreaker generates very low cutting force and delivers higher accuracy. It is the best choice for stainless steels and free cutting steels.<\/li>\n<\/ul>\n<p>MicroNega system features:<\/p>\n<ul>\n<li><strong>Double-sided<\/strong> negative inserts <strong>working like a single-sided positive insert <\/strong>with cost-performance advantages.<\/li>\n<li>The use of <strong>indexable style<\/strong> in small-size boring, instead of solid boring tips, offers more <strong>technical choices<\/strong> and <strong>cost-performance advantages<\/strong> than conventional boring tools.<\/li>\n<li>An <strong>optimized bar shape<\/strong> made with a special alloyed steel with optimized distribution of material over the section ensures the best <strong>rigidity <\/strong>and <strong>stiffness <\/strong>to the tool holder avoiding chattering and vibrations during operation.<\/li>\n<li>The specific <strong>chip evacuation pocket design<\/strong> offers multiple chip evacuation routes, <strong>improving the chip evacuation<\/strong> and helping preserve the <strong>hole wall surface quality.<\/strong><\/li>\n<li>The <strong>special chip breaker<\/strong> is tailored for small boring operation: it reduces the cutting force, improves cutting precision, enables stable and smooth cutting, improves chip flow and evacuation.<\/li>\n<\/ul>\n<p>MicroNega technology is available in a <strong>special kit<\/strong> that includes the most frequently used sizes of boring bars, a box of inserts, and necessary accessories packed in a practical and robust toolbox.
