| Cutting Method | Typical Applications | Precision & Tolerances | Cost & Efficiency |
|---|---|---|---|
| CNC Saw Cutting | Investment casting cutoff, structural alloy bar sizing, industrial parts cutting, near-net-shape billet preparation, and high-volume raw material sectioning. | Tight tolerances cutting typically holding ±0.1 mm to ±0.3 mm; repeatable accuracy with controlled perpendicularity and low kerf loss. | Excellent throughput; minimal thermal impact on hard-to-machine alloys; low cost-per-cut for low to high volume production. |
| CNC Grinding | Removal of stubborn residual gate witness on casting profiles, surface flattening, and ultra-precise dimensional finish work on hard alloys. | Achieves sub-millimeter dimensional precision and exceptional surface finish quality, often down to Ra 0.4 μm or better. | Lower material removal rates; higher consumables cost; best utilized as a secondary finishing step rather than bulk cutting. |
| Sinker EDM & Wire EDM | Intricate tool and die manufacturing, complex internal geometries, thin-walled aerospace components, and parting of ultra-hard exotic metals. | Extreme precision reaching tolerances of ±0.005 mm; completely burr-free cuts regardless of material hardness. | Very low processing speeds; high machine-hour costs; limited to specialized low-volume or prototype applications. |
When to Choose Precision Production Cutting
