SMEC SL 4500 / 1250 (SL 4500A) CNC LATHE

Technical Description

This is a mid-sized 2-axis CNC lathe engineered for precision turning operations with substantial workpiece capacity. The machine features a 30.5-inch swing over bed, enabling machining of parts up to 26.77 inches in turning diameter, supported by an 18-inch chuck for secure workholding and a 4.65-inch bar capacity for automated stock feeding. The dual-axis configuration (X and Z) provides efficient control over tool positioning, with the X-axis regulating radial cuts and the Z-axis controlling longitudinal movement along the workpiece. An integrated automatic tailstock offers support for extended workpieces, enhancing machining stability and precision for longer components. The machine is controlled by a Fanuc Oi-TF CNC control system, delivering reliable automation and repeatability essential for production runs. At 22,046 pounds, the lathe provides substantial mass and rigidity to minimize vibration during cutting operations, supporting consistent tolerance maintenance. This configuration is well-suited for producing symmetrical and moderately complex turned parts in automotive, aerospace, and general manufacturing applications. The combination of swing capacity, spindle bore, and automatic tailstock makes this lathe versatile for both small-batch custom work and higher-volume production, capable of achieving the precision levels typical of modern CNC equipment while maintaining operational efficiency and ease of setup.
