Daishin Seiki Corporation 50th anniversary.

Mr. Omachi: Our goal was to reach the limit of simultaneous 5-axis milling. We wanted our work to serve as a challenge to the pioneers of 5-axis.
Our reasons for choosing a helmet were both practical and artistic. First, we considered the work size. The project had to be less than 400mm since that was the maximum stroke of the machine tool. Secondly, we wanted to choose a subject that would be familiar to anyone at a glance.
I imagined a simple and free model within the 400mm sphere and I hit on the idea of a helmet. A typical motorcycle helmet was too simple to suit our needs. An off-road/motocross helmet gave us more flexibility in design. Our final design reflects the skills and experiences we have developed over our last 50 years as a manufacturing company.
