Rotating part, spindle
; Switch on cross drilling attachment.
; Set main spindle to 0° immediately,
the program will advance to the next block straight
away.
; Switch on the drill while the spindle is taking up
position.
; Wait for the main spindle to reach its position.
; Feedrate in mm/min (G96 is suitable only for the
multi-edge turning tool and synchronous spindle, but
not for power tools on the cross slide.)
; The spindle is positioned through 90° with read halt
in a positive direction.
; The spindle is positioned at 180° relative to the
spindle zero point.
; The spindle turns in a positive direction through 90°
from the absolute 180° position, ending up in the
absolute 270° position.
