DESIGNING
One of the major accuracy for any tool is to get it designed
with appropriate parameters to check the profile
accordingly as it provides fast, accurate simulation of all the
tools produced. In all stages of manufacture, each tool is
rigorously inspected for its every element with design and
accuracy specifications.
The tooth profile of Gear Hobs, Shaper Cutters, Milling
Cutters, Slitting Cutters or any non-standard tools are
computer aided design which allows rapid assessment of
individual cutting requirements and ideal optimization of all
variables for maximum cutter effectiveness.
