GPM-ST300 Square Tube Beveling Machine: Automotive Parts Manufacturing Case Study

NODHA partner GIRET used the GPM-ST300 Square Tube Beveling Machine to provide professional processing services to Shandong Yuncheng Longxin Machinery Co., Ltd., performing beveling operations on automotive shafts and square tube components. The machine's efficient and precise operation successfully met the customer's needs.

I. Customer Background

Strict Precision Requirements: Automotive axles and square tube components must withstand complex loads. Beveling angles and flatness directly affect welding strength and assembly accuracy. Traditional manual beveling equipment is prone to angle deviations and burr residue, leading to insufficient weld pass rates and increased rework costs.

Low Efficiency: Manually grinding each square tube takes several minutes and is difficult to guarantee consistency, becoming a bottleneck in the production line.

Inconsistent Quality: Beveling angles and blunt edge dimensions vary greatly depending on the operator, directly affecting the quality and efficiency of subsequent welding.

Urgent Need for Multi-Specification Compatibility: The customer's production involves square tubes with specifications of 80/80~300/300mm and round tubes/shafts with diameters of φ80~300mm and wall thicknesses of 5-20mm, primarily made of high-strength carbon steel. Traditional equipment cannot efficiently handle multiple specification switching, requiring frequent and time-consuming adjustments.

II. Equipment Adaptation Scenarios

Multi-Specification Compatibility: The equipment supports square tubes 80/80~300/300mm and shafts... Machining ranges from φ80 to 300mm, with wall thicknesses covering 5-20mm, perfectly matching existing customer product specifications. Multiple component models can be processed without equipment replacement, significantly reducing equipment changeover and debugging time.

High-efficiency feed system: Equipped with a 0-1500mm/min steplessly adjustable feed speed, the machining rhythm can be flexibly adjusted according to component material and wall thickness, ensuring cutting stability for thick-walled components while improving machining efficiency for thin-walled components, adapting to different working conditions of automotive parts.

High-precision machining guarantee: Utilizing a CNC system to precisely control the cutting trajectory, the bevel angle error is controlled within ±0.5°, resulting in a smooth, burr-free forming surface, fully meeting the precision requirements of automotive parts welding and assembly, effectively improving the subsequent welding pass rate.

Stable and Reliable Operating Performance: The circulating water cooling system effectively controls cutting temperature, preventing thermal deformation of components; the rigid bed and precision transmission components ensure stability during long-term continuous operation, making it suitable for mass production scenarios of automotive parts.

III. On-site Applications of Automotive Parts

1. High-Efficiency Batch Processing, Improving Operational Efficiency

For customers' batch order needs, the GPM-ST300 demonstrates high-efficiency operation capabilities. Its adjustable feed rate allows for low-speed, stable cutting of thick-walled components to ensure machining quality; high-speed feed for thin-walled components further increases production capacity, achieving "dual excellence in quality and efficiency."

2. Precise Beveling, Ensuring Welding Quality

The cutting surface is smooth and free of burrs, cracks, and thermal deformation. The multi-jaw self-centering clamping system precisely positions components, preventing misalignment during processing and ensuring beveling symmetry and consistency, laying the foundation for subsequent automated welding and assembly.

3. Convenient Operation and Safety Assurance: The equipment's user-friendly design significantly reduces the operational threshold and safety risks. The CNC interface is intuitive and clear; workers only need to input parameters such as component specifications and bevel type to automatically generate a processing plan. New operators can operate independently after short training. The fully enclosed protective structure and safety interlock devices effectively prevent the splashing of cutting chips and the risk of misoperation, ensuring operator safety.

IV. Customer Feedback

The GPM-ST300's continuous and stable operation provides enterprises with production capacity to handle larger orders, reduces rework and scrap, and improves overall product quality and market competitiveness.
