A big layer board of double track way for numerically control grinder

The utility model relates to a lathe field, specific big layer board of double track way that relates to a numerically control grinder. This kind of a big layer board of double track way for numerically control grinder, big layer board passes through drive arrangement and installs on the numerically control grinder lathe bed its characterized in that: big layer board includes the layer board body, the both sides of this layer board body respectively be equipped with a guide rail and one of them strip for the level gauge, another is for hydrostatic guideway, big layer board is moved on the lathe bed along two tracks by drive control. Above -mentioned a big layer board of double track way for numerically control grinder especially is fit for driving medium -sized, heavy roll and rotates, and feeding and returning of saddle is removed along two hydrostatic guideway for it is higher that the static pressure of saddle floats the accuracy of measurement, adjust sensitiveer, operation more steady, thus improve the s
