CNC Five-axis Machined Aluminum Parts For Semiconductors
Semiconductor-grade aluminum alloys (such as 6061 and 5052) are soft and prone to tool sticking. Sharp cutting tools with a large rake angle are essential to avoid built-up edge. Oil-based cutting fluids should be used, not water-based, to prevent oxidation.
Description
Core Features of Five-Axis Machining
1. Multiple Degrees of Freedom (DOF) for Efficient Machining of Complex Surfaces
Traditional three-axis machine tools are limited to linear motion in X/Y/Z. Five-axis machines add two rotational axes (A/B/C, for example, A+B, B+C, etc.), enabling multi-angle positioning of the tool or workpiece.
2. Reduced Clamping Times and Improved Precision
Five-axis machine tools achieve "one-clamping, multi-surface machining" by rotating the worktable or tool head angle, eliminating the cumulative errors caused by repeated positioning.
3. Optimizing Tool Cutting Angles for Improved Surface Quality
By adjusting tool tilt angles (e.g., swarf cutting and tool tip avoidance), the optimal cutting contact point is consistently maintained, preventing the problem of zero centerline speed in ball-end cutters.

Characteristics of Semiconductor Aluminum Parts
1. High Purity and Special Alloy Requirements
Material Purity: Semiconductor-grade aluminum alloys (such as 6061 and 5052) typically require high purity (≥99.5%) to minimize impurity contamination in semiconductor processing.
2. High Precision and Tight Tolerances
Dimensional Accuracy: Critical dimensional tolerances typically require ±0.01mm, with flatness ≤0.02mm/100mm.
Surface Roughness: Non-contact surfaces require Ra ≤1.6μm, while contact surfaces (such as vacuum seals) require Ra ≤0.4μm, or even mirror polish.
