Metal CNC Machining Parts
For industries demanding the highest levels of accuracy and repeatability in complex components, Metal Precision CNC Machining is the definitive solution. Our advanced CNC systems produce high-performance cnc machining parts from a wide array of raw materials, engineered to meet stringent specifications. A cornerstone of our service is Aluminum CNC Machining, leveraging the material's excellent strength-to-weight ratio and machinability for parts in aerospace, automotive, and robotics. Whether you require prototypes or full-scale production runs, our expertise in CNC Machining Aluminum and other metals ensures every component is fabricated with meticulous attention to detail, surface finish, and dimensional integrity.
The manufacturing of Metal CNC Machining Parts is a sophisticated process governed by precise parameters that define the final product's quality, functionality, and fit. Understanding these specifications is crucial for engineers and procurement specialists. Below are the key material and machining parameters we meticulously control.
Common Material Grades & Properties
- Aluminum 6061-T6: Excellent weldability, corrosion resistance, and medium strength. Ideal for structural frames and automotive parts.
- Aluminum 7075-T6: High strength, comparable to many steels. Used in aerospace and high-stress applications.
- Stainless Steel 304: Superior corrosion resistance and formability. Common in food processing and marine hardware.
- Stainless Steel 316: Enhanced corrosion resistance, especially to chlorides. Suited for chemical and medical applications.
- Carbon Steel 1018: Good balance of strength, ductility, and machinability. Widely used for pins, shafts, and fixtures.
- Carbon Steel 1045: Higher strength and wear resistance. Excellent for gears and structural components.
- Brass C360: Outstanding machinability and good corrosion resistance. Perfect for decorative and electrical components.
Standard Machining Tolerances
| Feature Type | Standard Tolerance | High Precision Tolerance |
|---|---|---|
| Linear Dimensions | ±0.005" (0.127 mm) | ±0.001" (0.025 mm) |
| Hole Diameters | ±0.002" (0.051 mm) | ±0.0005" (0.013 mm) |
| True Position (GD&T) | Ø 0.010" (0.254 mm) | Ø 0.002" (0.051 mm) |
| Surface Finish (Ra) | 63 μin (1.6 μm) | 32 μin (0.8 μm) or better |
Key Process Parameters
- Maximum Part Size: Up to 60" x 30" x 24" (1524 mm x 762 mm x 610 mm) on our large-format CNC mills.
- Axis Capability: 3-axis, 4-axis, and 5-axis simultaneous milling for complex geometries.
- Tooling: Utilization of carbide and diamond-coated end mills for optimal material removal and finish.
- Coolant Systems: High-pressure through-spindle coolant for efficient chip evacuation and thermal management.
- Inspection: First-article and in-process inspection using CMM (Coordinate Measuring Machine) and laser scanners.
