Vertical Lathe
Confirmed operational. Vertical turning capability for large-diameter castings — flanges, housings, ring forms.
Why CNC EDM in a Casting Foundry Is Rare and Valuable
Most Vietnam casting factories outsource mold repair and complex cavity work to specialist EDM shops — introducing additional lead time, split accountability, and subcontractor quality risk. Dai Minh Phat's in-house EDM brings three advantages:
In-House Mold Repair
EDM precision-repairs worn or damaged mold cavities without full mold replacement. Faster engineering changes and lower tooling maintenance cost vs. outsourced mold repair.
Electrode Geometry Control
EDM burns require precisely machined graphite or copper electrodes. In-house electrode machining means the factory controls electrode geometry accuracy — directly affecting cavity surface quality and dimension.
Complex Post-Cast Features
Narrow keyways, deep slots, and complex internal profiles that exceed casting tolerance can be EDM-finished in-house — one roof, no split accountability.
CNC EDM vs Conventional EDM vs CNC Milling — For Casting Mold & Post-Machining Work
| Factor | CNC EDM | Conventional EDM | CNC Milling |
|---|---|---|---|
| Repeatability across orders | ✓ Programmed — exact repeat | Operator-dependent | ✓ CNC programmed |
| Hardened steel capability (60+ HRC) | ✓ Excellent | ✓ Yes | Limited by cutter wear |
| Complex 3D cavity profiles | ✓ Full 3D CNC path | Limited to 2D+ | ✓ 5-axis possible |
| Zero cutting force on workpiece | ✓ Thermal erosion only | ✓ Yes | Cutting force present |
| Mold cavity repair precision | ✓ Ideal | Good (limited geometry) | Limited by hardness |
| Dolphin Audit Pillar 2 signal | ✓ Strongest signal | Medium signal | Strong signal |
Vertical Lathe + CNC Horizontal Lathe — Full Post-Cast Machining Coverage
Dai Minh Phat's dual-lathe setup covers the complete spectrum of post-cast machining requirements — from large-diameter flanges on the vertical lathe to precision cylindrical turning on the CNC horizontal lathe.
| Factor | Vertical Lathe | CNC Horizontal Lathe |
|---|---|---|
| Best part geometry | Large-diameter discs, flanges, ring housings, pump casings | Cylindrical shafts, bushings, connectors, coupling elements |
| Heavy casting handling | Gravity self-centers heavy parts | Limited by horizontal chuck |
| Sealing face / flat face turning | ✓ Natural geometry advantage | Possible but less rigid |
| Precision ID/OD tolerances | ±0.02–0.05mm | ±0.01–0.02mm |
| Cast flange / valve body machining | ✓ Primary tool | Secondary (smaller parts) |
| Dolphin Audit buyer impact | Covers large cast parts — flanges, housings | Covers precision turning — shafts, sleeves |
