Guiding accuracy

以及滑軌和支承件的熱變形等。導向精度是指運動構件沿導軌導面運動時其運動軌跡的準確水平。影響導向精度的主要因素有導軌承導面的幾何精度導軌的結構類型導軌副的接觸精度外表粗糙度導軌和支承件的剛度導軌副的油膜厚度及油膜剛度。直線運動導軌的幾何精度一般包括：垂直平面和水平平面內的直線度；兩條導軌面間的平行度。導軌幾何精度可以用導軌全長上的誤差或單位長度上的誤差表示。

And the thermal deformation of the sliding rail and supporting components. Guidance accuracy refers to the accurate level of the motion trajectory of the moving component when it moves along the guide surface of the guide rail. The main factors affecting guidance accuracy include the geometric accuracy of the guide rail bearing surface, the structural type of the guide rail, the contact accuracy of the guide rail pair, the surface roughness of the guide rail and the stiffness of the support components, and the oil film thickness and stiffness of the guide rail pair. The geometric accuracy of linear motion guides generally includes: straightness in the vertical and horizontal planes; The parallelism between the two guide rail surfaces. The geometric accuracy of the guide rail can be expressed as the error in the total length of the guide rail or the error per unit length.

精度堅持性

Accuracy persistence

另外，精度堅持性是指滑軌工作過程中保持原有幾何精度的能力。導軌的精度堅持性主要取決于導軌的耐磨性及尺寸穩定性。耐磨性與導軌副的資料匹配受力加工精度潤滑方式和防護裝置的性能的因素有關。導軌及其支承件內的剩余應力也會影響導軌的精度堅持性。

In addition, accuracy persistence refers to the ability to maintain the original geometric accuracy during the operation of the sliding rail. The accuracy of the guide rail mainly depends on its wear resistance and dimensional stability. The wear resistance is related to factors such as the matching of the data of the guide rail pair, the precision of the force processing, the lubrication method, and the performance of the protective device. The residual stress inside the guide rail and its supporting components can also affect the accuracy of the guide rail.

運動平穩性

Motion stability

導軌運動平穩性是指導軌在低速運動或微量移動時不出現爬行現象的性能。平穩性與導軌的結構導軌副材料的匹配潤滑狀況潤滑劑（作用：能減少或避免摩擦磨損）性質及導軌運動之傳動系統的剛度等因素有關。

The smoothness of guide rail movement refers to the performance of the guide rail that does not exhibit crawling during low speed or slight movement. The smoothness is related to factors such as the matching lubrication condition of the structure and material of the guide rail, the properties of the lubricant (which can reduce or avoid friction and wear), and the stiffness of the transmission system of the guide rail movement.

運動靈敏度和定位精度

Motion sensitivity and positioning accuracy

直線模組運動靈敏度是指運動構件能實現的行程；定位精度是指運動構件能按要求停止在指定位置的能力。運動靈敏度和定位精度與導軌類型摩擦特性運動速度傳動剛度運動構件質量等因素有關。

Linear module motion sensitivity refers to the stroke that the moving component can achieve; Positioning accuracy refers to the ability of moving components to stop at designated positions as required. The motion sensitivity and positioning accuracy are related to factors such as the type of guide rail, friction characteristics, motion speed, transmission stiffness, and mass of motion components.

剛度

Stiffness

這對于精密機械與儀器尤為重要。直線導軌變形包括導軌本體變形導軌副接觸變形，導軌抵抗受力變形的能力。變形將影響構件之間的相對位置和導向精度。兩者均應考慮。

This is particularly important for precision machinery and instruments. Linear guide rail deformation includes deformation of the guide rail body, contact deformation of the guide rail pair, and the ability of the guide rail to resist force deformation. Deformation will affect the relative position and guidance accuracy between components. Both should be considered.

抗振性與穩定性

Vibration resistance and stability

而穩定（解釋:穩固安定；沒有變動)性是指在給定的運轉條件下不出現自激振動的性能。抗振性是指導軌副接受受迫振動和沖擊的能力。

And stability (explanation: stability and stability; no fluctuation) refers to the performance of not experiencing self-excited vibration under given operating conditions. Vibration resistance refers to the ability of the guide rail pair to withstand forced vibration and impact.
