The SB316 is fixed rail bridge machine designed for heavy cutting applications. This machine features roller guides, a hydraulic counterbalance system on the headstock, and a powerful spindle. These features allow for highly precise and accurate cuts without sacrificing speed.
The SB316YM model has extended Y-axis travel with 5-face machining capabilities to allow for the machining of complex workpieces. This machine features automatic tool changes in the vertical and horizontal orientations and offers automatic clamping of the headstock. Headstock options include 30 degree, 90 degree, extension, and manual universal.
