Turning benefits from high stiffness and low vibration at the cutting point. Hydrostatic turning spindles give 5–10× rolling-bearing stiffness with oil-film damping for better surface and roundness.
При токарке дробь и овальность идут от податливого шпинделя. Гидростатика в 5–10 раз жёстче, сопротивляясь прогибу.
Плёнка гасит вибрацию, биение ≤0,1 мкм, без ползучести. MRDY — с трёхкулачковым или вакуумным патроном.
Лучшая круглость, чистота и повторяемость без износа.
Tiện bị rung và oval do trục mềm. Thủy tĩnh cứng gấp 5–10 lần, chống võng.
Màng giảm chấn, biên ≤0,1 μm, không bò. MRDY dùng mâm 3 chấu hoặc chân không.
Tròn hơn, nhẵn hơn, lặp lại tốt không mòn.
Au tournage, le bruit et l'ovalisation viennent d'un palier souple. L'hydrostatique est 5–10× plus rigide.
Le film amortit, défaut ≤0,1 μm, sans rampement. MRDY avec mandrin 3 mors ou à vide.
Meilleure rondeur, finition, répétabilité sans usure.
Beim Drehen führen Ratter und Ovalität oft auf ein nachgiebiges Lager. Hydrostatik ist 5–10× steifer und widersteht der Durchbiegung.
Der Film dämpft, Rundlauf ≤0,1 μm, kein Kriechen. MRDY mit Drei-Backen- oder Vakuumspannfutter.
Bessere Rundheit, feinere Oberfläche, gleichbleibend ohne Verschleiß.
In turning, chatter and poor roundness often trace back to a compliant spindle. A hydrostatic turning spindle provides 5–10× the stiffness of a rolling-bearing design, resisting deflection under cutting force.
The oil film damps vibration at the source and keeps the shaft non-contact, so radial runout stays at or below 0.1 μm and low-speed operation is crawl-free. MRDY hydrostatic turning spindles can be paired with a three-jaw chuck or vacuum chuck depending on the workpiece.
Better roundness, finer surface finish, and consistent results from the first part to the last—without bearing wear changing the process mid-life.
