Universal Dividing Heads

A S N Industries offers a Universal Dividing Head, ASN UDH-100. It is a precision accessory for milling machine facilitating variety of tool room work. It is used along with various machines like milling, drilling, grinding and inspection. It is compact in design, rigid in construction and made out of close-grained heavy-duty cast iron. It has provision for holding components, between centres or with three jaws chuck as well as on the mandrels. The spindle nose is threaded for mounting back plate to receive the chuck. The threads are protected by knurled cap while operating without chuck. The spindle is mounted on precision ball bearings and is locked in position after each indexing operation before machining (except when performing helical flute milling) which reduces the machining loads on worm pair. The spindle axis can be titled 10 degree below and horizontal 100 degree above horizontal plane. Direct indexing: a jig bored index plate with 24 holes facilitates dividing of 2, 3, 4, 6, 8 12 and 24 stations. During direct indexing the worm and the worm wheel remain disengaged. Indirect indexing: indirect indexing is through worm and worm wheel (transmission ratio 1:40) by using index plate (4 per set). Division of all integers from 1 to 400 except prime number can be obtained. Differential indexing: by connecting the change gears between spindle (horizontal proposition only) and differential gear shaft at the bottom, the divisions up to 400 can be obtained. Helical flute milling: connecting the UDH on the machine table to the lead screw of the milling machine by suitable change gears mills helical flutes. It has a wide range of applications in tool manufacture, gears, splines, polygonal components, drills, milling cutters, hobbing cutters, end mills, reamers, jigs, and fixtures etc.
