Turning Inserts – Heavy Duty (HDT)
Cuatro ranuras para virutas de alta resistencia (TCH, HD2, HD5, HD8), además de una ranura de desbaste 909+ y una gama específica para titanio.
La gama HDT de Galtona amplía el programa de torneado de tamaño negativo para trabajos pesados y exigentes, desde desbaste medio hasta corte interrumpido completo.
Cuatro ranuras de viruta específicas se adaptan a la profundidad de corte: TCH (2.5–10 mm), HD2 (1.5–12 mm, nueva geometría positiva afilada para aceros de alta resistencia), HD5 (2–12 mm) y HD8 (2.5–12 mm, apta para cortes uniformes, uniformes y interrumpidos).
La ranura 909+ ofrece cobertura para desbaste medio y grueso en perfiles CNMG, SNMG y TNMG, además de plaquitas redondas RCMT, en grados GTCP125, GTCP135 y GTCK120, específico para hierro fundido.
También incluye una gama dedicada de titanio para torneado ("S15") con geometría rompevirutas IPE+ en formas de insertos CNMG, DNMG, SNMG, TNMG, VNMG y WNMG.
