Why are customized CNC machined parts so expensive?
I. High Equipment and Technical Costs
Advanced Equipment: CNC machining requires the use of specialized CNC lathes, which integrate high-precision mechanical components, advanced control systems, and complex sensors, making them expensive.
Technical Expertise: CNC machining involves complex programming techniques that require professional technicians for design and operation. These technicians must possess extensive programming experience, a deep understanding of the machine tools, and the ability to resolve issues that may arise during the machining process.
II. High-Precision Machining Requirements
Micrometer-Level Precision: CNC machining can achieve micrometer or even nanometer-level precision, which is unmatched by other traditional machining methods. To ensure such precision, high-quality raw materials, precise machine tools, and strict quality control and inspection processes are required.
High-Quality Materials: To achieve high-precision machining, CNC machining typically uses high-quality raw materials, which also have a relatively high cost.
III. Complex Machining Processes
Multi-Axis Synchronization: Some parts have complex designs that require multi-axis synchronization and multi-layer machining. This places high demands on the CNC lathes and increases the difficulty and cost of machining.
Extended Machining Time: Complex parts often require longer machining times and consume more resources. This not only increases direct production costs but may also affect the utilization rate of the machine tools and overall production efficiency.
IV. Other Cost Factors
Customized Part Machining: Non-standard parts, special hole positions, and specific clamping tools require additional fees.
Surface Treatment: Many products require special process treatments such as manual polishing, electroplating, oxidation, laser engraving, powder coating, and silkscreen printing after machining, which increase costs.
Other Risk Costs: Thin-walled parts, elongated workpieces, and others that have risks of scrap or deformation, as well as workpieces that require special machining tools for more precise machining or have cumbersome machining steps and require reduced machining speeds, will all affect the final price.
