A representative precision grinding case shows how a hydrostatic spindle's sub-micron runout, stiffness, and oil-film damping translate into consistent mirror finishes and stable accuracy over long batches.
Прецизионное шлифование требует отсутствия вибраций и стабильности. Обычные шпиндели вносят биение, ползучесть, нагрев и износ.
Гидростатический шпиндель плавает на плёнке 3–50 мкм с биением ≤0,1 мкм, жёсткостью >500 Н/мкм и демпфированием.
Зеркальная поверхность и допуски стабильны по всей партии, точность не падает со временем.
Mài chính xác cần không rung và ổn định. Trục thường gây biên, bò, nóng và mòn.
Trục thủy tĩnh nổi trên màng 3–50 μm, biên ≤0,1 μm, cứng >500 N/μm, giảm chấn.
Bề mặt gương và dung sai ổn định suốt lô, độ chính xác không giảm.
Le meulage de précision exige rotation sans vibration et stable. Les broches classiques apportent défaut, rampement, chaleur et usure.
Broche hydrostatique sur film 3–50 μm, défaut ≤0,1 μm, raideur >500 N/μm, amortissement.
Surfaces miroir et tolérances stables sur la série, précision constante.
Präzisionsschleifen verlangt schwingungsfreie Rotation und Stabilität. Normale Spindeln bringen Rundlauf, Kriechen, Wärme und Verschleiß.
Hydrostatische Spindel auf 3–50 μm Film, Rundlauf ≤0,1 μm, Steifigkeit >500 N/μm, Dämpfung.
Spiegelflächen und Toleranzen stabil über die Charge, Genauigkeit sinkt nicht.
Precision grinding of hard, tight-tolerance parts demands vibration-free rotation and thermal stability. Conventional spindles introduce runout, stick-slip, and heat that limit finish and geometric accuracy, and they wear—drifting the process over time.
A hydrostatic grinding spindle floats the shaft on a 3–50 μm oil film with radial runout at or below 0.1 μm, stiffness above 500 N/μm, and oil-film damping. The film carries heat away evenly and never wears.
Operators see consistent mirror finishes and held tolerances from the first part to the last in a long batch. Because accuracy does not degrade with use, first-article and in-process qualification stay valid, cutting scrap and rework.
