Both of these rotary table machines are travelling column types featuring a horizontal wheel axis. The travelling column, in line with all of the other machine axes, moves on pre-loaded hydrostatic bearings to enhance accuracy and eliminate overhang error. The spindle drive is capable of carrying grinding wheels measuring 400 mm diameter by 50 mm wide, with a 127 mm bore diameter.
The Delta Rotax 7 and 9 Compact Plus machines offer maximum grinding diameters of 700 and 900 mm, along with maximum grind heights with a new wheel of 330 mm and 530 mm. The vertical axis speed of both machines is 1.5 m/min.
