Description
Vhu – as a boring device - considerably increases possibilities of boring, drilling and milling machines. These heads are suitable for precision boring of cylindrical holes, and for machining of external cylindrical surfaces. The boring head Vhu by means of an automatic slide feed makes possible facing, backfacing and taper machining. The slide feed 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. |

Description 2
The screw (34) serves for quick adjusting of slide and, on the contary, the worm with the scale is used for fine adjusting of precision boring. (1 division = slide movement of 0,05 mm.) These heads are delivered with primary accessories in wooden boxes. The taper shank is wxchangeable and it is not a component of primary accessories. Therefore it is necessary to order taper shank as a special item. The boring heads Vhu 110/Vhu 160 are modifications of the basic Vhu 80 resp. Vhu 125 types; they have extended slides and screws. |
