Cast iron surface plate
The cast iron platform is referred to as the platform, which is also called the cast iron plate. That is the basic plane reference measuring tool for workpiece inspection, scribing, debugging equipment, assembly, welding and riveting. Cast iron platforms are classified into 0, 1, 2 and 3 according to accuracy levels. 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. They are widely used in machinery manufacturing, chemical engineering, hardware, aerospace, petroleum, automobile manufacturing, Instrumentation manufacturing and other industries.
Cast iron platform installation support accessories: platform brackets, adjustment horns, ground anchors, jacks, etc. When installing, it should be adjusted to the level and the load is distributed on each fulcrum. When the ambient temperature is used, vibration should be avoided.
