In gear hobbing, the hob and workpiece must rotate with extreme steadiness. Hydrostatic support gives both axes non-contact, high-stiffness, vibration-damped rotation—protecting flank accuracy and surface finish batch after batch.
Точность фланга и чистота определяются устойчивостью вращения фрезы и заготовки.
Обе оси плавают без контакта — нет биения и износа. Жёсткость >500 Н/μm и демпфирование гасят дробь.
Повторяемая точность класса 6, стабильная в сериях, так как плёнки не изнашиваются.
Độ chính xác flan và bề mặt do độ vững xoay dao và phôi.
Hai trục nổi không tiếp xúc — không biên, không mòn. Cứng >500 N/μm và giảm chấn triệt rung.
Cắt răng chính xác lặp lại class 6, ổn định lô dài vì màng không mòn.
La précision du flanc et la finition dépendent de la stabilité de rotation de la fraise et de la pièce.
Les deux axes flottent sans contact—pas de défaut ni d'usure. Raideur >500 N/μm et amortissement coupent le bruit.
Taillage précis et répétable classe 6, stable en série, car les films ne s'usent pas.
Flankenqualität und Oberfläche hängen von der Stetigkeit von Fräser und Werkstück ab.
Beide Achsen schweben kontaktfrei—kein Rundlauf, kein Verschleiß. Steifigkeit >500 N/μm und Dämpfung unterdrücken Rattern.
Wiederholbare Klasse-6-Genauigkeit, stabil in Serien, da die Filme nicht verschleißen.
A gear's flank accuracy and surface finish are decided by how steadily the hob and workpiece rotate during the cut. Any runout, vibration, or drift transfers directly onto the tooth form.
Because both the hob spindle and the workpiece table float on non-contact oil films, there is no bearing runout or wear to corrupt the geometry. Oil-film stiffness above 500 N/μm resists cutting-force deflection, and oil-film damping suppresses the chatter that would mark tooth surfaces.
The result is repeatable, high-accuracy gear cutting—class 6 per GB/T 10095—with consistency maintained across long production batches, since the supporting films do not wear. For precision gear manufacturing, hydrostatic support is not optional refinement; it is the foundation of the accuracy.
