The material of the maintenance inspection platform from North Heavy Industries is generally divided into cast iron and granite. The cast iron material is high-strength gray cast iron HT200-300, while the granite material is premium "Jinan Black" natural stone, with precision that can reach grade 00.
The maintenance inspection plate, also known as the cast iron inspection platform or marble inspection plate, is used for various inspection tasks, serving as a reference plane for precision measurements; it is used as a measurement reference for machine tool mechanical inspections, checking the dimensional accuracy or geometric deviations of parts, and for precise marking. It is an essential tool for bench workers in maintenance tasks and is also an indispensable basic tool in mechanical manufacturing.

It is known as a laboratory-grade inspection workbench.
The manufacturing process of the maintenance inspection platform generally involves scraping and grinding processes.
The maintenance inspection platform is typically packaged in wooden cases.
Maintenance methods for cast iron inspection plates: 1. The plate must be placed horizontally. Use a level to measure and adjust its horizontal accuracy in mutually perpendicular 90° directions to prevent loss of flatness due to gravity; 2. During hoisting, protective measures should be taken where the wire rope contacts the plate; 3. During use, handle workpieces gently to avoid damaging the plate surface, and ensure that no burrs on the workpieces scratch the plate; 4. After use, spread an oil-soaked felt cloth over the plate surface to prevent external impacts and rust; 5. Use a wooden cover made of plywood (three-ply or five-ply) to cover the plate and felt cloth when not in use.
The maintenance inspection cast iron plate is a new material plate developed only in recent decades. Its mechanical properties are similar to those of medium-carbon steel. Due to its excellent casting performance, ductile cast iron is increasingly widely used.
