Key Takeaways:
Rotary table accuracy is graded by positioning and repeatability. Hydrostatic tables reach ±0.001 mm positioning—understand how that compares to mechanical grades and what it enables.
How 精度 Is Graded
回转 tables为graded by 回转定位精度 (how close以 commanded angle)与repeatability (consistency across cycles). Mechanical tables为limited by 轴承 径向跳动与thermal drift; 静压 tables remove 那些 limits.

静压 Grade
丸作精工 静压 直驱 回转 tables achieve 回转定位精度的≤ ±0.001 mm. 该 places them at top的 精度 grade, suitable用于five-轴 machining, optics,与metrology 其中 mechanical tables cannot follow.
What Grade Enables
A finer grade means tighter tolerances, better 表面粗糙度,与 ability以hold 精度 through long cycles与varying loads—directly translating以higher-value, lower-scrap production.
