The boring head VHU by means of an automatic slide feed makes possible facing, back-facing and taper machining. The slide fee is adjustable in three or four grades and is stopped on adjustable dog by the pin clutch. The feed is derived from the rotary motion of the head, if one of the feed is adjusted, the pin of the clutch is put in and the brake ring is held by means of the stop bar.
