SCHIESS 3 K350 Heavy-Duty CNC Machining Machine

Description

This heavy-duty SCHIESS 3 K350 machine represents a large-scale industrial machining system designed for demanding production and heavy-component machining applications. The machine was originally built in 1984 and subsequently underwent a significant modernization and conversion by ROTTLER in 2008, incorporating a Siemens S840 control system. The combination of the original SCHIESS machine structure and later Rottler modernization provides a robust platform intended for industrial machining operations where high machine rigidity, large working dimensions, and reliable performance are important. The machine features a substantial gantry-style construction with two large vertical columns supporting a heavy crossbeam and machining assembly. Its rigid construction is designed to accommodate large and heavy workpieces while maintaining the structural stability required for industrial machining. The large enclosed working area is protected by a dedicated yellow safety guarding system, providing a controlled machining environment around the main working zone. According to the information displayed on the machine identification board, the machine provides approximately 4,000 mm × 1,600 mm of travel, offering a large working envelope for machining sizable components. The machine is also equipped with an 80 kW drive, indicating a substantial power capacity appropriate for heavy industrial machining requirements. The stated maximum workpiece weight is up to 60 tonnes, making the machine suitable for applications involving exceptionally large and heavy industrial components. The machine has been configured for turning operations (Drehbearbeitung) and is described on the equipment information sheet as being capable of turning work with sufficient accuracy for industrial requirements. The available information also indicates its use for industrial production orders in a one-shift operation. This makes the machine particularly relevant for heavy engineering environments where large components require controlled machining and turning processes. The ROTTLER modernization carried out in 2008 is an important part of the machine's configuration. The modernization incorporated a Siemens S840 CNC control system, providing the machine with an updated control platform compared with its original configuration. The visible control console includes the operator interface, display, control buttons, selector switches, and emergency-stop functions required for operating and monitoring the machine. The machine's physical construction demonstrates its suitability for heavy-duty industrial environments. The large vertical columns, reinforced crossbeam, extensive machining area, protective guarding, and dedicated control station are characteristic of equipment intended for machining components that exceed the size and weight capabilities of conventional machine tools. Its configuration allows operators to work with large components while maintaining a protected and organized machining area. The surrounding safety enclosure consists of heavy-duty yellow steel framing with mesh panels and access protection around the machine. Transparent protective panels are also positioned around portions of the machining area, providing visibility of the working zone while maintaining operator protection. The overall installation reflects a production-oriented industrial machine setup rather than a compact workshop machine. With its 4,000 × 1,600 mm stated travel, 80 kW drive, and maximum stated workpiece weight of 60 tonnes, the SCHIESS 3 K350 occupies a category of machinery intended for large-scale industrial machining. Its historical SCHIESS construction, combined with the 2008 Rottler conversion and Siemens S840 CNC control, makes it a substantial piece of equipment for heavy engineering and large-component machining applications. The machine can be considered for applications where large workpieces require industrial turning and machining operations, particularly in sectors involving heavy engineering, large fabricated components, energy-related equipment, transportation equipment, and other applications where component dimensions and weight demand a large-capacity machine tool. Actual suitability for a specific application should be confirmed against the complete machine specifications, tooling configuration, current condition, and required machining tolerances. Overall, this SCHIESS 3 K350, originally manufactured in 1984 and modernized by Rottler in 2008, presents a heavy-duty industrial machining solution with a large working envelope, high-power drive, substantial workpiece capacity, and Siemens CNC control. The machine's robust construction and large machining capacity make it suitable for organizations looking for equipment capable of handling demanding large-scale industrial machining requirements.
