Cast Iron Coordinate Lineation Surface Plates

  • Introduction
Jinggong Cast Iron Coordinate Lineation Surface Plates serves as the datum plane for precise measurement and all kinds of inspection/lineation tasks. Some coordinate lines on the working surface are convenience for measurement at any time. 
The raw material of the plates is the high-strength cast iron GG20-GG30 (HT200-300). After two times annealing treatment, the plates have the features of steady precision and abrasion resistance.
The size range is from 100mm*100mm to 3000mm*8000mm. Larger one can be made according to the drawing.
