FAQs of Dorries 2100 mm Swing Ram-type CNC VTL Machine:
Q: How is the Dorries 2100 mm Swing Ram-type CNC VTL machine installed and what are the foundation requirements?
A: The Dorries 2100 mm CNC VTL requires installation on a reinforced concrete foundation to support its approximate weight of 28,000 kg and ensure stability during heavy-duty operations. This reinforced base minimizes vibrations and inaccuracies, contributing to long-term machine performance. Professional installation is recommended for optimal setup and calibration.
Q: What types of workpieces and industries benefit most from this VTL machine?
A: This CNC VTL is ideal for heavy industries that process large, round componentssuch as energy, shipbuilding, machinery manufacturing, and aerospace sectors. Its capacity to handle workpieces up to 10,000 kg and 2100 mm swing diameter makes it particularly suitable for producing industrial parts, flanges, rings, and pressure vessel components.
Q: When should the ram and spindle settings be adjusted, and how is this managed?
A: Ram and spindle settingssuch as speed and strokeshould be adjusted based on the material, workpiece size, and required surface finish. Adjustments are made directly from the CNC touchscreen interface, where operators can program spindle speeds up to 250 RPM and set ram strokes, ensuring optimal machining performance for each job.
Q: Where does the machine handle cooling, lubrication, and safety operations during turning processes?
A: Integrated within the machine structure, the 400-liter coolant tank and automatic centralized lubrication system manage both cooling and lubrication, supporting consistent cutting and tool longevity. Comprehensive safety is ensured via emergency stop buttons, door interlocks, overload, and short circuit protection circuits throughout the operational area.
Q: What is the typical process for changing tools and how does the tool magazine contribute to productivity?
A: Tool changes are performed automatically through the machines tool magazine, which accommodates up to 10 tools. Operators can pre-program tool changes via the control panel, minimizing downtime and increasing throughput during multi-step machining operations. This feature is pivotal for complex or batch production runs.
Q: How does using a CNC VTL of this type improve operational efficiency and product quality compared to manual lathes?
A: The Dorries 2100 mm Ram-type CNC VTL offers precision automation, consistent repeatability (0.01 mm), and programmable control that manual lathes simply cannot match. This results in faster cycle times, minimal setup errors, efficient handling of large components, and higher quality, uniform output over extended production periods.
