Graphite Milling Tool

High-Performance PCD Tools for Precision Graphite Machining

Conquer the extreme abrasiveness of graphite and unlock significant productivity gains with ZYsuperhard’s specialized PCD Graphite Machining Tools. While graphite is invaluable in Mold & Die (EDM electrodes) and Semiconductor manufacturing, its abrasive nature rapidly destroys conventional carbide tools. Our PCD tools, including precision end mills and potentially specialized drills, are the definitive solution, engineered for extended tool life, high-speed capability, and superior precision in graphite milling and drilling operations.

Why PCD Excels in Graphite Machining:

• Unmatched Abrasion Resistance: Polycrystalline Diamond’s hardness provides incredible resistance to graphite dust abrasion, resulting in tool life potentially 50 to 100 times longer (or more) than uncoated carbide tools, minimizing costly downtime.
• Superior Sharp Edge Retention: Maintaining a sharp edge is crucial for cleanly shearing graphite, minimizing chipping/breakout. PCD excels at this, producing superior surface finishes and enabling the creation of fine details and sharp corners, especially vital for EDM electrodes and ensuring clean hole walls when drilling.
• High Thermal Conductivity: Allows for significantly higher cutting speeds and feed rates compared to carbide (often far exceeding a 50% increase), boosting productivity without risking tool damage.
• Reduced Dust Issues: The clean shearing action generates more manageable chips/dust compared to the fine powder from rapidly wearing carbide, potentially simplifying extraction.

Key Design Features for Graphite Machining Tools:

• Optimized PCD Grades: Utilizes premium PCD grades selected for the optimal balance of wear resistance and toughness demanded by graphite machining.
• Ultra-Sharp, Precision-Ground Edges: Manufactured with exceptionally keen cutting edges and precise geometries essential for clean milling cuts and precise drilling. Polished flutes often incorporated to aid dust/chip evacuation.
• Application-Specific Geometries: Available as End Mills (Flat, Ball Nose, Corner Radius options; 1-flute to multi-flute designs) optimized for various milling tasks. Drills (if offered) feature specific point geometries for efficient hole creation. All tools designed with appropriate back angles (typically ≥ 10°).
• Solid Carbide Body: Provides the high rigidity and stability necessary for vibration-free, high-precision milling and drilling.

Core Applications:

Our PCD tools are the industry standard for high-performance milling and drilling of various graphite grades:

• EDM Electrode Manufacturing: Primarily milling complex 3D shapes, sharp corners, thin ribs, fine details, and achieving the ultra-smooth surface finishes essential for optimal EDM performance and mold accuracy.
• Graphite Molds & Crucibles: Accurately milling graphite molds for glass forming, casting, or semiconductor processes; drilling precise locating or mounting holes.
• Graphite Fixtures & Components: Contour milling, pocketing, slotting, facing, and drilling features in graphite fixtures, jigs, bearings, seals, and other functional parts.
• Graphite Plate Processing: Efficiently face milling, milling slots, drilling holes, and creating smooth, burr-free chamfered edges.
