The company will feature the GTS-FX CNC turning center. As the flagship of the company's CNC turning series, the model employs a "back working" or "pick oft" spindle, a programmable vertical cut-off axis and a secondary tooling station. These additional components allow the machining of front and back operations on a single workpiece.
 Bar fed parts are machined on the first side (including any milling or cross drilling that may utilize the full C axis of the main spindle). Upon completion of the first side, the main spindle and the secondary spindle synchronize. The sub spindle collet or chuck close to grip the workpiece. With both the sub and main spindle gripping the part, the independent cutoff tool advances to part the half-completed component from the bar stock. With the sub spindle now in control of the workpicce, the secondary tool slide advances, and all backworking operations are completed.
