jainex aamcol Marine Lines, Mumbai, Maharashtra

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.

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.

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.

Fixed position hob for generating teeth on ratchet wheel. This hob unlike a conventional hob can cut without forming a fillet.

These milling cutters are made out of high alloy super high speed steel; with precision ground or unground forms; with straight or helical flutes for shear cutting; continuous or intermittent (staggered) cutting teeth; with or without chip breakers; radial, positive or negative rake tooth faces; with radial, axial or undercutting clearances; individual, gang or solid sections. As cutter teeth are cam relieved, only rake faces need to be sharpened with changing the tooth form through their full life. Cutter accuracy is maintained as long as they are accurately resharpened. This simplifies tool maintenance and provides more consistent quality. These cutters provide high degree of accuracy and efficient cutting geometry and hence ordinary cutters can be comparable in no way with these Jainex Aamcol special cutters.

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.

Spline gauge is an inspection tool used to quickly ascertain the acceptability of Internal/External splines or serration dimensions. It check cumulative effect of various dimensions and permissable errors to confirm suitability for assembly of component(s). Thus, it helps in mass production to achieve perfection to micro level eliminates need for skilled hands.

Special multistart hobs for components having block teeth like indexing splines.

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.

jainex aamcol offers precision form relieved ground or unground profile cutters ranging from standard single angle, double andgle, convex/conclave cutters to most complex intricate profile cutters like end mill type gear cutters, spline milling cutters, turbine blade profile milling cutters, etc. these milling cutters are made out of high alloy super high speed steel; with precision ground or unground forms; with straight or helical flutes for shear cutting; continuous or intermittent (staggered) cutting teeth; with or without chip breakers; radial, positive or negative rake tooth faces; with radial, axial or undercutting clearances; individual, gang or solid sections. as cutter teeth are cam relieved, only rake faces need to be sharpened with changing the tooth form through their full life. cutter accuracy is maintained as long as they are accurately resharpened. this simplifies tool maintenance and provides more consistent quality. these cutters provide high degree of accuracy and efficient cutting geometry and hence ordinary cutters can be comparable in no way with these jainex aamcol special cutters. some important applications of these cutters are highlighted below: * spur gear teeth milling for specific number of teeth or in sets of 8 and 15 cutters of is or bs standards. * sprocket teeth milling cutters, precision ground or unground profile * rack teeth milling of highest accuracy, single or multistrand, precision ground or unground profiles * worm thread milling, roughing or finishing, ground or unground form * spline milling on universal or hurth type machines * special serration milling on m/c chuck-jaws, automobile con-rod jaws, etc. * special narrow & deep groove milling on automobile con-rods

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.
