| Jainex Aamcol tools can meet the largest range of teeth cutting. Starting from finer pitch of 0.3 module to heavy-duty hobs up to 24 module are standard range. Hobs for different applications such as spur/helical gears, double helical herringbone gears, involute splines, key splines, serrations, ratchet wheels, chain sprocket wheels, HTD timer pulleys, worm gears, duplex type hobs, etc. are specialities of Jainex Aamcol. Hobs can be designed with special modifications like generating type, fixed position, short lead, entry roughing lead designs, blocked teeth, etc. depending on requirement of part. |

From
0.3 module to 24 module in accuracy class ‘C’ to ‘AA’
with finishing, pregrinding or roughing profiles with various profile
design modifications such as semi topping, protuberance, tip relief.
For generating parallel or angular splines; straight
or helical splines offered with profile modifications like semi
topping, undercutting, shoulder clearance, etc. Finishing or pregrinding
hobs are offered with precision unground or ground profile depending
on component accuracy requirements.
For
sprockets as per ANSI, BS, IS or any other standards or with non-standard
forms. For timer pulleys as per BS/HTD or any other standards or
non-standard profiles. These hobs are offered with ground or unground
profiles and topping or non-topping designs.
To achieve desired contact patterns – prime
requirement on hobbed worm gears, Jainex Aamcol have developed their
expertise through long extensive mathematical modelling, data simulation
and practical applications. Hobs can be hollow type or integral
shank type depending upon strength constraints. Tangential, radial,
topping or non-topping hobs and special reaming type finishing hobs
are also offered.
Fixed
position hob for generating teeth on ratchet wheel. This hob unlike
a conventional hob can cut without forming a fillet.
Special multistart hobs for components having block
teeth like indexing splines.
The
solution for efficient and economical hobbing of large size gears
of coarse pitch (5 module & above) requiring subsequent teeth
finishing operation. The special chip breakers provided on roughing
starts allow heavy feed rates to be applied without overloading
hob and hobbing machine. This reduces peak jerk loading on machine
and ensures accurate part quality.
Jainex Aamcol has developed special combination hobs
having roughing and finishing sections on one piece monoblock and
split two piece construction. Roughing section is provided with
special chip breakers allowing more efficient cutting even at higher
cutting speeds /feeds
