Gear Cutting Tools

The indexable carbide inserts
must completely cover the cutting
edges of the cutter tooth. The necessary
number of indexable inserts
and their arrangement depend
on the dimensions of the
inserts and on the size of the gear.
To render the pre-cutting of the
gear optimal for skive hobbing or
grinding, the carbide hobs with indexable
inserts can be made so
that they produce both a root
clearance cut (protuberance) and a
chamfer on the gear (see fig. below).
In the range from module 5 to
module 10 each cutter tooth only
holds one insert, which covers the
entire flank length.

From module 11 onwards, each
flank is fitted with an indexable insert
offset to the opposite flank. In
special cases, versions with a
single insert covering each flank
are also possible with these module
sizes.
