How Dual-Servo Round Bending Machines Enhance Tube Processing Quality

In the field of tube processing, the roundness control and surface quality of thin-walled tube fittings have always been key industry concerns. Particularly for thin-walled tubes made of materials such as stainless steel and high-strength steel, issues such as excessive ovality, surface marks, and wrinkling are highly prone to occur during the rolling process, severely affecting the performance and appearance of downstream products.

Addressing this industry pain point, the XS Series dual-servo round bending machine, launched by Zhangjiagang Xuesong Precision Technology Co., Ltd., offers a new solution for high-quality thin-walled tube bending with its innovative dual-servo drive system and precision mold design.

Dual-Servo Drive: Ensuring Both Precision and Efficiency
Traditional round bending equipment often uses hydraulic drives, which come with drawbacks such as slow response, difficult precision control, and high energy consumption. The XS Series adopts a dual-servo motor independent drive design, where the feeding servo and the diameter-adjusting servo work in coordination to achieve precise control of the bending process.

Precision Structural Design: Ensuring Long-Term Stable Operation
In the design of core components, the XS Series also strives for excellence. The spindle diameter increases with the model (40mm/55mm/80mm), and the mold diameter ranges from 136mm to 228mm, ensuring rigid support for processing large-diameter tubes. The minimum straight section length is 70mm, providing sufficient space for tube end processing.

The machine operates on 3-phase 380V 50Hz industrial power. The XS-80CNC model weighs up to 3,500 kg, and its stable frame structure effectively suppresses processing vibrations, ensuring long-term precision stability.

Application Case: From Automotive Components to Industrial Pipe Fittings
In a practical application at an automotive parts company, the XS-60CNC was used for the round bending of liquid cooling tubes for new energy vehicle battery packs. The customer reported that the equipment operates stably, tube roundness error is controlled within 0.2mm, the surface shows no obvious marks, and production efficiency increased by over 40% compared to the original equipment.

In the future, Zhangjiagang Xuesong Precision Technology Co., Ltd. will continue to optimize its dual-servo round bending technology, providing higher-quality tube processing equipment to customers across various industries.
