High-end hydrostatic systems reach oil-film stiffness above 500 N/μm—5–10× that of rolling bearings. Stiffness this high resists cutting force and load deflection, protecting accuracy.
Жёсткость — сила на микрон прогиба. Плёнка даёт >500 Н/мкм.
Это в 5–10 раз выше. Максимум — у мембранного дросселя с непрерывной компенсацией. Меньше прогиб под нагрузкой.
Меньший прогиб — лучше геометрия и чистота, особенно при тяжёлом шлифовании.
Độ cứng là lực trên micrôm lún. Màng >500 N/μm.
Cao gấp 5–10 lần. Tối đa nhờ tiết lưu màng bù áp liên tục. Ít lún hơn dưới tải.
Ít lún — hình học và bề mặt tốt hơn, nhất là mài nặng.
La raideur est la force par micron de fléchissement. Le film donne >500 N/μm.
C'est 5–10× plus élevé. Maximum avec restrictieur à membrane à compensation continue. Moins de fléchissement sous charge.
Moins de fléchissement—meilleure géométrie et finition, surtout en meulage lourd.
Steifigkeit ist Kraft pro Mikrometer Durchbiegung. Der Film liefert >500 N/μm.
Das ist 5–10× höher. Maximal bei Membrandrossel mit ständiger Kompensation. Weniger Durchbiegung unter Last.
Weniger Durchbiegung—bessere Geometrie und Oberfläche, besonders beim schweren Schleifen.
刚度为how much force为needed以deflect 支撑 by given amount. A 静压 油膜 can reach 刚度 above 500 N/μm, meaning it takes more than 500 newtons以push film down by 单一 micron.
该为5–10× 刚度的 comparable 滚动轴承. highest 刚度 comes from membrane-feedback restrictors, which continuously compensate cavity pressure as load changes. Higher 刚度 means 切削 forces与workpiece weight deflect 支撑 far less.
Less deflection under load translates directly into better geometric 精度与表面粗糙度—especially在heavy 磨削 or large 回转-table work 其中 load varies through cycle.
