EDM Graphite
Fine Detail. Smooth Surfaces. Consistent EDM.
Isostatic EDM Graphite
What We Machine
Electrodes that fit your job
From large-cavity roughers to thin-wall finishers, we machine one-piece or segmented electrodes, customize the fit to your equipment, and label our electrodes.
- Fins, slots, and thin-section finishing electrodes (tight detail, smooth surfaces)
- Block/segment roughers for fast material removal
- Multi-electrode sets (rough, semi-finish, and finish)
- Electrode fit to your equipment or fixturing tooling
- Serial numbering, engraving, and kit labeling for clean hand-offs
How We Machine
Consistent geometry, clean edges, less bench work
Graphite is machined differently. We use tooling built specifically for EDM graphite to maintain edge integrity, control corner radii, and hold square in tall sections, reducing touch-up work before EDM.
- High-speed milling strategies to protect edges and corners
- Practical tolerances on length, square, and parallelism for accuracy
- Controlled surface finish to reduce bench work before final EDM
- Graphite-specific machining and packaging that protects critical faces in transit
Grades We Work With
Match the grade to your operation
We select from a globally recognized family of EDM graphite grades—including an ultra-fine 5 µm grade for detail finishing—so you can balance detail, wear, and throughput across roughing and finishing passes.
- Detail finishing: ultra-fine grain (≈5 µm) for thin cross-sections and smooth surfaces
- General finishing: fine grain for stable detail and good wear
- Roughing: tougher grades sized for high removal rates and durability.
- Ask us about grade availability and stock, or explore raw material details on our Specialty Graphite page.
Operational Gains from Precision Graphite Machining
Purpose-built electrodes and clean hand-offs shorten setup time, reduce bench work, and make EDM runs more predictable, shift after shift.
- Faster setups with kit-assembled electrodes for your system
- Smoother surfaces and crisp detail on fine features
- Predictable wear from roughing through finishing
- Interchangeable spares backed by repeatable tolerances
Quality, Documentation, and Support
Every order goes through a preventive quality program. Shipments include clear IDs and lot traceability with the respective grade; upon request we provide first-article checks and measurement reports for electrode length, square/parallelism, and controlled surface finish. We serialize and assemble by operation to your equipment standard, include Certificates of Conformance when required, and use graphite-specific packaging that protects edges and surfaces.
Share your equipment standard, desired finish, and rough/semi-finish/finish sequence. We will recommend a grade and machine an electrode to your tolerances.
