Gear cutting machine use a rotating, multiple-tooth cutting tool called a hob for generating teeth on spur gears,worm gears, helical gears, splines, and sprockets. More gears are cut by hobbing than by other methods because the hobbing cutters cuts continuously and produces accurate gears at high production rates.
Hobbing is a machining process for making gears, splines, and sprockets on ahobbing machine,
which is a special type of milling machine. The teeth or splines are progressively cut into the
workpiece by a series of cuts made by a cutting tool called a hob. Compared to other gear forming
processes it is relatively inexpensive but still quite accurate, thus it is used for a broad range of parts
and quantities.
Features
* By continuous indexing, it is suitable to cut cylindrical spur, helical geras and sprockets under
axis feeding.
* It can also cut worm wheels by a worm-wheel hub under radial feeding.
* Machine feeding by manual.
* It is suitable for mine, oil, ship, engineering mechanism industries for making large gears.
* Tangential hob head is also available for special order to cut worm wheels under tangential
feeding mode.
