Achieving a breakthrough in outer diameter super-finish polishing, especially in the recessed areas of a workpiece, has been made possible with the innovative W cross-guide method, which offers three-dimensional movement!

We’re thrilled to introduce our cutting-edge super finisher, the “DOUBLE CROSS HEAD”. This device not only maintains the benefits of conventional film-type superfinishing but also incorporates a three-dimensional film feed mechanism and a unique head structure. These enhancements enable the polishing of the outer diameter of deep inner surfaces of cylindrical workpieces—a task that was challenging with traditional film-type superfinishing.

Moreover, the adoption of a film guide system marks a significant advancement. Additionally, the overpass method, which is distinctive to the film-type super-finishing approach, simplifies the setting of the film path. This innovation not only stabilizes the film tension but also prevents deviations, ensuring a consistent and high-quality finish across various applications.
