Gear cutting tools are ready
for the future - LMT TOOLS
Tool development will continue to follow the sporting motto “higher, faster,
further” in the future. It signifies the striving for even higher performance, higher
cutting speeds and feeds and a longer tool life with the objective to reduce
manufacturing costs whilst meeting the required workpiece quality. There are
also new challenges for precision tools from future trends such as downsizing or
lightweight design. Components that are smaller, yet more efficient are made
from higher-strength materials. To reduce weight, composite materials are now
lso on the rise.
A
nd gear hobs, in particular, must meet additional
requirements. The desire to be mobile is growing
around the world. In Asian regions such as China
and India, in particular, the demand for passenger cars is
growing, requiring more and more gears. Another aspect is
the development of automatic transmissions with more (up
to 9) stages, which again increases the demand for smaller
gears significantly.

There are some concerns that electric mobility represents a
danger for gears as gearboxes might no longer be needed for
these. However, this fear needs to be put into perspective as
both hybrid drives and purely electric drives still need gear
boxes, albeit the latter with fewer gear stages.
To meet the different performance and quality requirements
for gear cutting, LMT Tools teamed up with engineering
experts at LMT Fette as well as machine manufacturers,
