Sheet Metal Parts CNC Machined Parts Milled Parts is a kind of sheet metal processing product that combines sheet metal technology with CNC milling technology, mainly used for manufacturing metal structural components with complex shapes and precision requirements. The following is a detailed overview:
1. Definition and Process Characteristics
Definition
Sheet Metal Parts CNC Machined Parts Milled Parts refer to metal parts with uniform thickness formed by milling metal sheets (usually with a thickness of ≤6mm) through computer numerical control (CNC) technology, combined with sheet metal processes (such as shearing, punching, bending, welding, etc.).
Process characteristics
High precision and efficiency: CNC milling can achieve a high tolerance of ±0.0005 inches. Combined with sheet metal processing, it can mass-produce complex structural components such as chassis and shells.
Material diversity: Supports processing of various metals such as aluminum, stainless steel, copper, and steel, as well as engineering plastics.
Automation and flexibility: By programming to control tool movement, the processing path can be quickly adjusted to meet the requirements of complex geometers.
2. Application fields
Equipment enclosures and structural components: such as computer cases, electrical cabinet enclosures, car bodies, etc.
Non-standard customized parts: Meeting special functional requirements, such as precision mechanical components, industrial equipment brackets, etc.
3. Technological advantages
Cost-effectiveness: Compared with traditional processes, CNC milling can reduce labor costs while enhancing production efficiency through program optimization.
Quality stability: High-precision control ensures the consistency of part dimensions, reducing deformation and errors.
4. Processing flow
Design stage: Create a CAD model and convert it into a CNC program 5.
Material preparation: Fix the thin metal sheet on the workbench and install the milling cutter.
Automatic processing: The CNC system controls the milling cutter to remove material along the preset trajectory to form the desired shape.
Post-treatment: Surface treatments such as anodizing and electroplating can be carried out.
