Product Made In Japan
Manufacture: Yamashina Seiki
Model: Hollow Facing Machine

The motor pump’s body (pipe) will undergo machining for its inner diameter, outer diameter, and end surface. To enable machining on both the left and right sides of the workpiece, the machining units are designed to be opposed. Moreover, due to the characteristics based on the workpiece standard, the setup allows for internal clamping with a collet by making the mandrel pass through, achieving a hollow design. This ensures stable machining. Additionally, each of the left and right units is equipped with an ATC (Automatic Tool Changer) to accommodate a variety of workpieces.
