Cast Iron Surface Plate:
1.The cast iron platform is referred to as the platform, which is also called the cast iron plate.
2.That is the basic plane reference measuring tool for workpiece inspection, scribing, debugging equipment, assembly, welding and riveting
3.Cast iron platforms are classified into 0, 1, 2, 3 or fine machining according to accuracy levels.
4.Generally, Class 0, Class 1, and Class 2 plates are used as flat plates for inspection platforms. Platforms for Class 3 are used for scribing, assembly, welding, and riveting.
5.Accessories are available according to your requirement, like V, T, straight-shaped slots and tapped holes, long holes, grid lines, etc

The platform adopts scraping technology, precision grinding, hand scraping, and the accuracy is controllable.
The raw material of the cast iron surface table is the high-strength cast iron HT200-300 whose surface hardness is of HB170-240. After the two manual handling such as 600ºC to 700ºC artificial annealing as well as 2 to 3 years of natural aging, the T slot base plate perfectly resists abrasion and has stable precision.




Widely applied in the manufacturing and processing of machines, machining equipments, railway and tracks, automobiles, motorcycles, ships, pressurized containers, sheet metals, classis and cabinets, testing and measurement instruments and steel constructions.
