It is particularly suitable for high-precision milling scenarios of heavy-cutting and complex-contour iron molds. Combined with actual application cases, compared with traditional vertical/gantry machine tools, it reveals why it has become the preferred choice for high-end mold manufacturing, and shares the key points of daily maintenance to help users achieve long-term stable operation and productivity improvement.

Application Cases and Performance Optimization of Bridge-type Double-column Structure in the Manufacturing of Large Cast Iron Molds

In the manufacturing of iron molds, the stability of the machine tool directly determines the machining accuracy and efficiency. This article delves into how the bridge-type double-column structure enhances the overall rigidity of the machine through the design of a fixed crossbeam and workbench, effectively suppressing vibration transmission. It is particularly suitable for high-precision milling scenarios of heavy-cutting and complex-contour iron molds.

Common Problems in Iron Mold Machining

Iron mold machining often encounters issues such as accuracy deviation caused by vibration. Vibration during the machining process can lead to surface roughness of the mold increasing by up to 1μm, significantly affecting the quality and performance of the final product. Traditional vertical or gantry machine tools may not effectively address these vibration problems, resulting in limited machining accuracy and efficiency.

Principle and Advantages of Bridge-type Double-column Structure

The bridge-type double-column structure features a fixed crossbeam and workbench, which greatly reduces vibration compared to traditional structures. By fixing the crossbeam, the structure enhances the overall rigidity of the machine tool, effectively suppressing the transmission of vibration generated during the machining process. In practical applications, the surface roughness of the machined mold can be reduced by 0.5μm compared to traditional machine tools, and the machining accuracy can be improved by 30%.

Typical Application Scenarios and Performance Improvement Data

This structure is widely used in typical application scenarios such as the milling of large cast iron parts and inserts. In the machining of large cast iron parts, the bridge-type double-column structure can increase the machining efficiency by 40% compared to traditional machine tools. For complex contour inserts, it can improve the machining accuracy by 45%, ensuring the quality and precision of the final product.

Maintenance Points for Long-term Reliability

To ensure the long-term stable operation of the machine tool, regular maintenance is essential. Key maintenance points include lubricating the guide rails, controlling the thermal balance, and performing regular calibrations. By following these maintenance steps, the service life of the machine tool can be extended by up to 5 years, reducing the overall cost of ownership for users.

From an engineer's perspective, the bridge-type double-column structure represents a significant technological advancement in the field of mold manufacturing. It not only provides users with high-precision and high-efficiency machining solutions but also helps users achieve long-term stable operation and increased production capacity.

In conclusion, the bridge-type double-column structure has become the preferred choice for high-end mold manufacturing due to its outstanding performance and reliability. When you choose DC1113, you are choosing a trustworthy and high-quality machine tool. It combines advanced technology with user value, providing you with an unparalleled machining experience.
