Como as pastilhas CBN funcionam em condições de corte interrompidas ou ao usinar materiais com diferentes níveis de dureza?
Condições de corte interrompidas: In interrupted cutting, such as machining grooves, keyways, or interrupted surfaces, Pastilhas CBN demonstrate excellent resistance to chipping and fracturing compared to other cutting tool materials like carbide. The high hardness and toughness of CBN allow it to withstand the impact and shock loads encountered during interrupted cutting operations. Additionally, Pastilhas CBN can maintain sharp cutting edges for longer periods, resulting in improved productivity and reduced tool changeovers.
Materiais de usinagem com dureza variável: Pastilhas CBN excel in machining materials with varying hardness levels, including hardened steels, cast iron, and heat-resistant alloys. The exceptional hardness of CBN enables it to effectively cut through hardened materials without undergoing rapid wear or deterioration. Moreover, Pastilhas CBN exhibit stable performance across a wide range of hardness levels, providing consistent cutting performance and dimensional accuracy. This versatility makes Pastilhas CBN suitable for machining applications where multiple materials or workpieces with varying hardness levels are encountered.
Resistência ao calor: Pastilhas CBN offer superior thermal conductivity compared to other cutting tool materials like ceramics, which allows them to dissipate heat more efficiently during machining. This enhanced heat resistance helps prevent thermal deformation and tool wear, particularly when machining materials with varying hardness levels that may generate higher temperatures during cutting.
Acabamento de superfície e precisão dimensional: When machining materials with varying hardness levels or in interrupted cutting conditions, achieving a high-quality surface finish and dimensional accuracy is crucial. Pastilhas CBN are capable of producing fine surface finishes and maintaining tight tolerances even under challenging machining conditions. Their consistent cutting performance and resistance to wear ensure consistent part quality throughout the machining process.
Geral Pastilhas CBN são altamente eficazes em condições de corte interrompidas e na usinagem de materiais com diferentes níveis de dureza devido à sua excepcional dureza, tenacidade, estabilidade térmica e capacidade de manter arestas de corte afiadas. Essas características contribuem para melhorar a eficiência da usinagem, prolongar a vida útil da ferramenta e componentes usinados de alta qualidade.
