Precision Surface Grinder ESG-820A
  • The constructions of working table, saddle, column and wheelhead are made of high grade cast iron to ensure grinding stability and extend machine life.
  • All slideways are precisely handscraped and laminated with Turcite B allowing a low friction and stable movement to retain high accuracy.
  • The spindle is incorporated with several pieces of preloaded class 7(P4) super precision angular contact ball bearings in a constant temperature controled room.
  • Auto downfeed for "A" models are executed by stepping motor with surface,plunge,spark out and zero return grinding performances.(ESG-820/1224/1632)
