Cylindrical and internal grinding need exceptional shaft stability in a slender form. Hydrostatic spindles provide the stiffness and damping required for tight roundness and bore accuracy.
Шпиндели круглого/внутреннего шлифования длинные и гнутся. Гидростатика поднимает жёсткость без контакта.
Демпфирование гасит дробь, биение субмикрон держит отверстие правильным. Износа нет.
Серия MRDY закрывает круглое и внутреннее шлифование в одном корпусе.
Trục mài tròn/trong dài và dễ võng. Thủy tĩnh nâng độ cứng không tiếp xúc.
Giảm chấn triệt rung, biên submicrom giữ lỗ chuẩn. Không mòn.
MRDY gồm mài tròn và trong trong một khối.
Les broches de rectification sont longues et fléchissent. L'hydrostatique porte sans contact.
L'amortissement coupe le bruit, le défaut submicron garde l'alésage juste. Pas d'usure.
La série MRDY couvre rectification cylindrique et intérieure en un bloc.
Rundschleifspindeln sind lang und biegeschlaff. Hydrostatik hebt die Steifigkeit ohne Kontakt.
Filmdämpfung unterdrückt Rattern, submikroner Rundlauf hält die Bohrung wahr. Kein Verschleiß.
Die MRDY-Serie deckt Rundschleifen und Innenschleifen kompakt ab.
Cylindrical and internal grinding spindles are often long and slender, making them prone to deflection and vibration that ruin roundness and bore geometry. Hydrostatic support makes the shaft float on an oil film, dramatically raising effective stiffness without contact.
Oil-film damping suppresses the chatter that plagues internal grinding, while sub-micron runout keeps the bore true. The non-contact film means no wear changes the geometry over the spindle's life.
Marusaku MRDY hydrostatic spindles cover cylindrical and internal grinding duties, integrating the bearing and direct-drive motor for a compact, rigid package.
