KTB Series Multi-tasking Turning Center
Product Highlights
The KTB Series Multi-Tasking Turning Center is designed with enhanced rigidity and precision for complex machining applications. Featuring a single power turret with 12 standard tool stations and a linear Y-axis, it supports advanced milling functions. For increased versatility, customers can opt for a 16-tool turret and a sub-spindle, enabling more intricate operations while improving floor space efficiency and reducing labor costs. The machine’s 90-degree slant bed structure enhances chip disposal, improves accessibility, and lowers the center of gravity for superior stability. Additionally, the symmetrical saddle design ensures the X, Y, and Z axes remain perpendicular, with servo compensation optimizing positioning accuracy for high-precision machining.
