We believe in using the resources available to produce the best tools
possible. With advancements in 3D-CAD technology, it became clear that
we should take advantage. Back in February of 2000, Hitachi installed 27
sets of state-of-the-art 3D-CAD systems and adopted a design simulation
technology in order to shorten the development time and bring tools to
market faster and more efficiently.
Previously, a tool
was designed in two-dimensions on paper, a sample was cast and thousands
of dollars were spent to bring a demo model to life. Only then, could
it be tested and stressed to learn of its weaknesses. Once any problem
areas were discovered, solutions were devised and the process happened
all over again until it was perfected. All of this took time and lots of
money to get a product that was ready for market.
In 2000, Hitachi decided to forge ahead with a revolutionary
system that would allow them to virtually design and build a tool in
three dimensions using 3D-CAD.
Virtual analysis is done on all tools in order to determine where
failures are most likely to occur. Strength is tested, vibration
simulated, the impact of dropping is studied, operating under severe
environment is enacted, dust and dirt preventive measures are examined,
safety features are gauged, all in a significantly short period of time
with maximum efficiency. Engineers are now able to build a tool, test
it, discover problem areas and make improvements before the tool ever
becomes a reality.
Hitachi engineers have developed a unique Cool Flow System using
design simulation and 3D-CAD. Air flow characteristics are charted using
a web design and temperature monitoring in order to ensure a steady
stream of air reaches a tools rare-earth magnet motor. This internal
cooling system allows a tool to run longer and harder by minimizing the
risk of burnout.
So much engineering and precision is built into each and every
Hitachi tool before it reaches a production line and eventually hits the
market. By utilizing state-of-the-art technology, Hitachi is able to
reduce time to market by several months usually and deliver the highest
quality tool possible.
