EDM
Blind cavities and hard metal feature machining.
Suitable Applications
Complex part geometries, custom metal/plastic prototypes, and low-to-high volume production runs matching exact drawing tolerances.
Required Files
3D CAD files (STEP/STP format) for geometry, and optional 2D drawings (PDF/DWG) detailing critical tolerances, threads, or surface finishes.
DFM Checkpoints
Design for manufacturability (DFM) verification, material grade check, raw stock availability, process route definition, and QC planning.
Typical Parts & Use Cases
Common structural and precision parts manufactured with this machining method.
Housings & Enclosures
Protective enclosures for gearboxes, electronic assemblies, and sensor modules with critical alignment surfaces.
Brackets & Support Mounts
Structural plates and support components engineered to carry mechanical loads in robotic assemblies.
Precision Shafts & Pins
Cylindrical rotating axles, drive shafts, and locator pins requiring strict dimensional and circular runout tolerance.
Ground Plates & Manifolds
Flat mounting beds, custom tooling manifolds, and vacuum chambers with multi-hole patterns and smooth seal finishes.

DFM & Sourcing Review Matrix
How our engineering team reviews your design requirements before launching fabrication.
| Review Area | Buyer Input | Engineering Check | Output |
|---|---|---|---|
| CAD Files | STEP (.step) or STP (.stp) model; optional PDF drawing | File readability, geometry integrity, surface intersection check | Confirmed 3D database model |
| Material Grade | Specified grade (e.g. Al 6061-T6, SS 316) | Machinability, thickness allowance, stock raw material match | Raw material supply confirmation |
| Critical Dimensions | Annotated drawing tolerances and threading specs | Process limit check, tolerance stack compatibility | QC dimension monitoring list |
| Surface Finish | Specified roughness (Ra) or post-treatment (anodizing, plating) | Coating compatibility, jig location marking, thickness impact | Finishing route instruction |

Process FAQ
What files should I send for review?
Send your 3D CAD files in STEP (.step) or STP (.stp) format. If your design has tight tolerances, thread requirements, or specific finishes, please also attach a 2D PDF drawing with clear annotations.
Can material and finish requirements be reviewed together?
Yes. Our engineers review material compatibility with requested surface finishes to prevent coating thickness or tolerance issues.
What factors affect the machining route selection?
Part geometry, material hardness, tolerance requirements and order quantity determine whether milling, turning, EDM, grinding or another route is recommended.
