Drawing-based graphite CNC machining for high-temperature, electrical discharge, furnace, sealing, and wear applications.
Complete RFQs are easier to review within 1-2 business days when drawings, graphite grade, quantity, and destination are included.
| Option | Best Fit | Watchouts |
|---|---|---|
| Fine-grain isostatic graphite | Tighter details, thin walls, seal faces, threaded features, and parts that need consistent machining response. | Confirm minimum wall thickness, corner radii, and inspection datum before quoting fragile geometry. |
| Molded or extruded graphite | Larger thermal parts, furnace supports, spacers, and cost-sensitive shapes where the drawing allows wider tolerance. | Check grain direction, load path, and thermal shock exposure before copying a legacy drawing. |
| High-purity or treated graphite | Semiconductor, crystal growth, vacuum furnace, and contamination-sensitive programs. | Specify purity target, cleaning, packing, certificate expectations, and destination compliance needs at RFQ stage. |
Check geometry, tolerance intent, operating temperature, atmosphere, purity needs, and export document requirements.
Match graphite grade to function, then flag fragile features, thread risks, sharp corners, and unsupported spans.
Machine with graphite-specific dust control, edge protection, and handling rules for brittle features.
Inspect drawing-critical dimensions, clean handling surfaces as specified, and pack edges, slots, and labels for export shipment.
| Metric | Typical Range | Why It Matters |
|---|---|---|
| Typical tolerance | Application-specific, drawing controlled | Graphite is brittle and porous, so tolerances must match function and inspection method. |
| Material purity | Industrial to high-purity graphite | Semiconductor, furnace, and crystal growth projects often need low-ash material control. |
| Feature risk class | Thin wall, slot, bore, thread, seal face, or exposed edge | Feature class decides grade choice, cutter strategy, inspection focus, and packing protection. |
Yes. Send 2D drawings, STEP files, material grade, tolerance notes, and quantity. We can review manufacturability before quotation.
We can prepare order documentation and coordinate a compliance check by HS code, material specification, destination, and end use. Final shipment depends on the applicable rules at the time of export.
Start with the operating temperature, atmosphere, purity requirement, mechanical load, wear condition, and electrical or thermal function. Those inputs are enough for an initial grade recommendation and RFQ review.
