- Precision optical alignment stages
- CNC coordinate measuring machines
- Lithography equipment linear stages
Installation guidance:
Use 0.02mm/m grade reference surface. Torque mounting screws to 3.5N·m in
crisscross pattern. Perform parallel alignment within 0.03mm/m using dial indicator.
Relubricate every 100km travel or 6 months.
