The cast iron coordinate lineation surface plate serves as the datum plane for precise measurement and all kinds of inspection/lineation tasks. It can inspect the precision and accuracy deviation of the machinery parts size. There has some coordinate line on the working surface, it will convenience for measurement at any time. Currently, this kind of plate has become one of the indispensable tools in the machinery manufacturing industry.

The raw material of cast iron coordinate lineation surface plate is the high-strength cast iron HT200-300 whose surface hardness is of HB170-240. After two times annealing treatment, the cast iron surface plate has the features of steady precision and abrasion resistance.

The size range is from 100mm*100mm to 3000mm*8000mm. For the larger one, it can be used by the splicing method. In our factory, we also can make the special sized product according to your requirement.
