The customization of mechanical parts must adhere to relevant national and international quality standards and safety regulations (such as ISO and DIN) to ensure product reliability and compatibility. The customization process typically involves stages such as requirements consultation, design, sample fabrication, testing and validation, and mass production. During the requirements consultation phase, the client must provide detailed information regarding application scenarios, performance requirements, and budget constraints. In the design phase, engineers develop multiple design options based on the client's needs. Following sample fabrication, rigorous testing and validation are conducted to ensure compliance with design specifications. Finally, the project proceeds to mass production, ensuring consistent product quality and adherence to delivery schedules.
Material Performance Standards
• Mechanical properties: Tensile strength (e.g., 45 steel ≥ 600 MPa), hardness (e.g., HRC 58–62)
• Special properties: High-temperature resistant alloys (e.g., Inconel 718, with an operating temperature of up to 700°C)
Surface Roughness Standards
• Classification: Ra 0.8–6.3 μm (precision machining), Ra 12.5–25 μm (rough machining)
• Special requirements: Surfaces of hydraulic components typically require a roughness of Ra < 0.4 μm.
Positional Accuracy Standards
• Common requirements:
• Coaxiality (e.g., coaxiality between motor shaft and bearing housing ≤ Φ0.01 mm)
• Parallelism (e.g., parallelism of gearbox shafting ≤ 0.02 mm)
• Perpendicularity (e.g., perpendicularity of flange mounting surface ≤ 0.05 mm)
