Cast Iron Surface Plate

Similar to the Granite surface plate, cast iron surface plate is also used as a flat datum base to carry out precise quality checks. However, a cast iron surface plate also allows the user to mount magnetic v-block that might be useful for measuring various dimensions or inspection of a work piece.

  • Made generally as per IS: 2285
  • Manufactured from good quality close grained high density alloyed cast iron castings conforming to Grade FG-220 of IS:210
  • Stress Relieved and hand scraped surface.
  • Provided with lifting handles and rexine cover.
