Abstract

Patente de Invenção: <B>"RODA DE CISALHAMENTO DE ALTA VELOCIDADE"<D>. Um método para obter desempenho de cisalhamento superabrasivo a partir de ferramentas que empregam grão mais económico, não-superabrasivo, convencional, envolve a operação da ferramenta abrasiva convencional a uma velocidade de contato tangencial ultra-elevada (isto é, pelo menos cerca de 125 m/s). Tais velocidades de operação ultra-elevadas podem ser obtidas com rodas de cisalhamento abrasivas segmentadas tendo segmentos formados de partículas vítreas ligadas por resina, de óxido de alumínio, óxido de silício, óxido de ferro, óxido de molibdênio, óxido de vanádio, carboneto de tungstênio, carboneto de silício e similares. Os segmentos abrasivos podem ser cimentados ao núcleo da ferramenta com um adesivo tal como cimento epóxi. Segmentos abrasivos podem ser feitos com uma profundidade significativamente maior do que os segmentos que contêm superabrasivos e, conseq³entemente, devem prover longa vida, assim como desempenho elevado. Adicionalmente, segmentos abrasivos convencionais são mais fáceis de retificar e desbastar e fazer em perfis intrincados para cisalhar peças de trabalho com formato complexo.
