Installation & Setup
Proper installation is essential for accurate performance. Surface plates must be positioned on level, firm surfaces without vibration. Installation involves placing pad iron supports, removing packaging materials, and precise leveling adjustment using appropriate tools and safety measures.
Usage Guidelines
- Distribute workpiece placement evenly across the surface to prevent localized wear
- Maintain cleanliness by preventing contamination from metal chips and abrasive particles
- Place workpieces gently to avoid impact damage to the precision surface
- Immediately repair any impact marks or raised areas to maintain accuracy
- Avoid hammering or percussive work directly on the plate surface
- Clean after each use and apply anti-rust oil for long-term storage protection
