CA8480 Flexible High Performance Digital Display Roll Lathe

The CA8480 digital display roll lathe is primarily designed for the semi-finishing and finishing machining of cast iron, steel, and non-ferrous metal rolls. With the use of high-speed steel, carbide, or other materials for cutting tools, it is capable of performing turning and repair operations on the rolls' outer diameter, end faces, as well as various complex hole profiles and curved surfaces. Additionally, it can be used to process shaft components made of cast iron, steel, and non-ferrous metals within the same size and weight range as the rolls, offering both semi-finishing and finishing capabilities for the outer diameter, end faces, and complex curved surfaces.

The machine's longitudinal guide rail system is designed with an integrated four-rail structure. The longitudinal movement is driven by a worm and gear mechanism, while the transverse feed motion of the tool rest utilizes high-rigidity rectangular guide rails. The combination of the Italian frame-type tool rest technology and a fixed tool post enhances the machine's cutting rigidity and stability. This robust design, particularly the high-rigidity tool post, is ideal for machining workpieces over the spindle center. The spindle bearings feature high-precision, adjustable radial clearance double-row cylindrical roller bearings, providing spindle rigidity, smooth rotation, and high precision.

The machine’s structural design emphasizes high stability and rigidity, ensuring comprehensive machining accuracy and, consequently, achieving precision for the workpieces. The spindle box (headstock) is equipped with a 45 Kw AC frequency motor, utilizing hydraulic automatic shifting. The machine's longitudinal and transverse movements employ stepless variable speed, allowing users to select appropriate speeds and feed rates based on the material of the rolls, ensuring ease of operation.

The longitudinal movement is facilitated by a grating digital display, eliminating the need for roller alignment or marking when turning the rolls. A centralized lubrication system ensures that all moving guide pairs receive precise, automatic lubrication at fixed intervals, guaranteeing dynamic response characteristics and long-lasting lubrication performance. Both the longitudinal and transverse movements are fully protected by stainless steel enclosures, ensuring the long-term maintenance of motion accuracy.

The machine is composed of the bed, spindle box, tailstock, tool rest, hydraulic system, PLC electrical control cabinet, and wire rack (tank chain), providing a highly stable and efficient solution for roll and shaft machining.
