- Optical inspection device positioning
- Desktop CNC micro-machining tools
 Installation recommendation: 
            Apply 0.02-0.05mm pre-tension during rail mounting to compensate for thermal expansion. 
            Use torque-controlled tightening (0.8-1.2Nm for M4 screws) to prevent rail deformation.
