1. Guiding accuracy

Guiding accuracy refers to the exact degree of trajectory when the component moves along the surface of slideway.
The main factors to effect the precision of guide are: geometry accuracy, the structure of guide, surface roughness degree, stiffness of rail and supporting parts, thermal deformation and so on.

2. Accuracy retention

Accuracy retention is mainly dependent on abrasion resistance of guide and stability of dimension

3. Motion sensitivity and static accuracy

Motion sensitivity and static accuracy is relative with type, friction characteristics, speed, component quality etc.

4. Motion stationarity

Stationarity is depending on the structure of slideway, lubrication status, and stiffness of drive system.

5. Vibration resistance

Have the performance of preventing self-sustained oscillation during rotation.

6. Stiffness

This is particularly important for precision machinery and instruments.

7. Technological structure

Try best to make manufacture and maintenance easier and save the cost.
