Ever since the production of our first centering machine in 1958, we have planned a line of products we refer to as the Gifu Sekigahara Double-Ends Processing Machine. Since then, delivery of more than 2,000 units has made us a top manufacturer. |
A rich variety of types and options are available, which means that we can work to any specification.
|
We have delivered machines that can complete processing of a single item in twelve seconds.
