When assessing a CNC Lathe, you must prioritize the Swing Over Bed and Maximum Machining Length to ensure your workpieces fit. Check the Spindle Speed (RPM) and Spindle Bore Diameter, as these dictate the material types and bar sizes you can process. For precision, verify the Positioning Accuracy and Repeatability (typically within ±0.005mm for high-end models). Additionally, ensure the Control System (e.g., Fanuc, Siemens, or GSK) is compatible with your team's programming skills and existing CAD/CAM software.
