PREMIER LTD PTB 105 CNC LATHE

Technical Description

The Rownd CNC Lathe is a precision horizontal turning center engineered for versatile production work with a notable 62.87-inch swing over bed capacity. This machine accommodates workpieces up to 5.25 inches in diameter and features an 11.27-inch maximum workpiece length, making it suitable for mid-range component manufacturing. The lathe utilizes a three-jaw chuck with an 80mm diameter and provides 110mm swing clearance over the cross-slide, enabling efficient chip evacuation and tool accessibility. Equipped with variable spindle speed ranging from 0-3000 RPM, the machine delivers maximum rapid traverse rates of 1000 mm/min in both X and Z axes, ensuring efficient cycle times. The CNC control system provides exceptional positioning accuracy of 0.0008 inches (0.02mm) with comparable repeatability, while the tool touch probe achieves 0.0002-inch accuracy for precise offset establishment. The machine incorporates an MT1 tailstock taper with 190mm travel capacity and features an ER11 tool interface supporting a four-position automatic tool changer. The robust aluminum and stainless steel construction provides dimensional stability, with overall footprint of 770x470x470mm and net weight of 55kg. Power delivery includes a 750W spindle motor, 400W fourth-axis spindle for rotational machining operations, and an integrated 8W laser engraver module. Operating on 100-240VAC single-phase or 220V three-phase input, the system draws maximum 1200-1400W depending on voltage configuration, making it suitable for standard industrial environments.
