1. Part Design Complexity Design Difficulty: Precision Hardware Machining Complex designs usually require more advanced processing technology and more processing steps, such as parts with special shapes, complex internal structures or high precision requirements, which will increase processing costs. Machining Steps: Complex designs may lead to an increase in processing steps, which in turn prolongs processing time and increases costs. 2. Material Selection Material Characteristics: Precision Hardware Machining Different hardware materials have different characteristics such as hardness, strength, corrosion resistance, etc., and their processing difficulty and cost are also different. For example, machining high-strength alloy steel requires stronger tools and higher cutting parameters than machining ordinary carbon steel, which will increase processing costs. Material price: Some special materials such as titanium alloy, superalloy, etc., due to their scarcity and processing difficulty, the price is usually higher, which in turn pushes up the processing cost. 3. Machining accuracy requires high-precision equipment: High-precision parts require more precision processing equipment and stricter quality control. The purchase, maintenance and operation costs of these equipment are higher. Quality control: High-precision processing usually requires longer processing time and higher technical level to ensure the dimensional accuracy and surface quality of the parts, thereby increasing the cost. 4. Order quantity scale effect: Mass production can reduce the processing cost of unit parts through scale effect. In large-scale production, the preparation cost of tooling fixtures can be allocated to more parts, and the production efficiency can also be improved at the same time. Small batch production: In contrast, small batch production because the economy of scale cannot be fully realized, the processing cost per unit part is usually higher. 5. Precision hardware machining process Special process: such as EDM, wire cutting processing, laser processing and other special processes, compared with traditional turning, milling and other processes, often require higher equipment investment and technical requirements, so that the processing price rises. Process selection: Different precision hardware machining processes have different cost characteristics. Enterprises need to choose the appropriate processing technology according to the specific requirements of parts and cost budget. 6. Other factors Labor cost: including the salary and benefits of precision hardware processing personnel, and the cost of personnel such as quality inspectors. Equipment cost: including the purchase or lease of processing equipment, as well as the cost of equipment maintenance and repair. Transportation and logistics costs: These costs are more pronounced when parts are transported and stored, especially when the processing location is far from the raw material or customer location. Market supply and demand: Processing prices may increase in areas or periods of high demand; in areas of intense competition, prices may be relatively low.
