Significant Features of Industrial Cast Iron Plates
As a cast iron inspection table supplier, we deliver IS standard cast iron surface plates, rust-resistant cast iron surface plates, and precision cast iron measuring plates. Our industrial cast iron plates meet the modern quality control requirements.
Flatness
Cast iron plates are available in multiple grades with flatness tolerances depending on size and standards.
Surface Finish
Top surfaces of cast iron plates are precision-machined to achieve high accuracy and repeatability.
Higher Capacity
They are perfect for heavy-duty applications such as tool setup, inspection, and layout marking.
Vibration Damping
They naturally absorb mechanical vibrations. So, they are suitable for CNC inspection and metrology tasks.
