Shenzhen Alu Rapid Prototype Precision Co., Ltd.

Design Creation

Process: A 3D model of the part is created using CAD software (e.g., SolidWorks, AutoCAD). The design specifies dimensions, tolerances, and features.

File Format: The CAD file is typically exported as a STEP, IGES, or DXF file for CNC programming.

 Shenzhen Alu Rapid’s engineers assist with design optimization for CNC compatibility, ensuring manufacturability.

Programming (CAM)

Process: The CAD model is imported into Computer-Aided Manufacturing (CAM) software, which generates toolpaths for the CNC machine. This includes instructions for tool selection, cutting paths, speeds, and feeds.

Output: The CAM software produces a G-code or M-code file, which the CNC machine reads to execute precise movements.

Shenzhen Alu Rapid uses advanced CAM tools to program complex toolpaths for high-precision parts.

Material Selection

Materials: CNC machining works with metals (e.g., aluminum, stainless steel, titanium), plastics (e.g., ABS, POM), and composites, chosen based on part requirements like strength or weight.

Form: The workpiece is typically a solid block, sheet, or billet. Shenzhen Alu Rapid offers a wide range of materials for CNC machining, complementing their AM capabilities.

Machine Setup

Process: The workpiece is secured to the CNC machine (e.g., mill, lathe, or router) using fixtures like vises or clamps. Tools (e.g., drills, end mills) are loaded into the machine’s tool changer.

Calibration: The machine is calibrated to ensure accuracy, setting the zero point and tool offsets.

Shenzhen Alu Rapid’s state-of-the-art CNC machines ensure precise setup for industries like aerospace and medical.

Machining Process

The CNC machine follows the G-code to perform operations, removing material to shape the part. Common operations include:

Milling: Rotating tools cut material from the workpiece (e.g., slots, pockets, or contours).

Turning: The workpiece rotates while a stationary tool cuts it (e.g., for cylindrical parts like shafts).

Drilling: Creates precise holes.

Grinding or EDM: Used for ultra-precise or hard materials.

The process is highly automated, with the machine controlling tool movements in multiple axes (3-axis, 4-axis, or 5-axis for complex geometries).

Shenzhen Alu Rapid uses 5-axis CNC machines for intricate parts, such as aerospace components or medical tools.

Post-Processing

Finishing: Parts may undergo deburring, polishing, anodizing, or coating to achieve desired surface quality or aesthetics.

Inspection: Dimensional accuracy is verified using tools like Coordinate Measuring Machines (CMM) or calipers to meet tolerances.

Shenzhen Alu Rapid integrates CNC machining with surface finishing and quality checks, ensuring production-ready parts.

Testing and Application

The finished part is tested for fit, function, or performance (e.g., stress testing for automotive components).

If needed, the design is refined, and the process repeats.

Parts are used for prototyping, production, or integration into assemblies.
