Cast Iron Surface Platesodern industrial gauges. It is suitable for a variety of inspection, precision measurement of the reference plane. Used for mechanical testing benchmarks of machine tools, dimensional accuracy or shaped inspect parts for deviation, and as close crossed, is an indispensable basic tool in the machinery manufacturing.

Cast Iron Surface Plates is widely used in machining, tool shop, machine (the seizure) repair workshop, large equipment base, measuring rooms and precision machining of the inspection, measurement and grinding, and can accurately measure, test workpiece flatness, straightness and tolerance of the angle.

The flatness of top surface varied from DIN876/0, DIN876/I, DIN876/II to DIN876/III. The raw material is high-strength cast iron GG20-GG30 (HT200-HT300), and the hardness is HB170-240.
