Graphite 4 Flutes Carbide End Mill Roghing Ballnose Solid Endmill
Introduction:
Features:
Material: Ultra-fine grain carbide – Resists abrasive wear from graphite.
Coating: Specialized graphite coating (e.g., diamond-like carbon/DLC or uncoated) to reduce edge buildup and friction.
Geometry:
Roughing-specific serrations (variable pitch) for reduced vibration and chip breaking.
Ballnose tip (radius = 1/2 of tool diameter) for smooth finishing passes after roughing.
Flutes: 4 flutes – Optimized for graphite’s brittleness (fewer flutes than metal-cutting endmills).
Helix Angle: Lower helix (10°–20°) to prevent graphite chipping.
Typical Applications:
Primary Use: Roughing and semi-finishing of graphite electrodes, carbon fiber, and brittle composites.
Industries: Mold/die-making (EDM electrodes), aerospace (composites), and electronics.
Machines: High-speed CNC mills, graphite-dedicated machining centers.
✔ Abrasion Resistance: Carbide substrate outlasts HSS in graphite.
✔ Chip Control: Serrated edges break graphite dust into manageable particles.
✔ Heat Management: Graphite-specific coatings reduce heat buildup.
✔ Ballnose Versatility: Combines roughing and 3D profiling in one tool.
Diameter: Common sizes: 3mm–20mm (e.g., 6mm ballnose).
Shank: 6mm (for a 6mm cutter) or straight shank.
Cutting Length: ~2–4× diameter (e.g., 12mm for a 6mm tool).
Overall Length: ~50–100mm.
Speed/Feed (Graphite):
RPM: 10,000–30,000 (depends on machine rigidity).
Feed Rate: 1,000–3,000 mm/min (varies with depth of cut).
