Product Description

Graphite 4 Flutes Carbide End Mill Roughing Ballnose Solid Endmill

Introduction

A Graphite-Specific Roughing Ballnose Endmill is a solid carbide tool designed for aggressive material removal in graphite electrodes, EDM applications, and composite machining. The 4-flute design balances chip evacuation and cutting stability, while the ballnose tip enables 3D contouring and detailed milling.

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.

Advantages

✔ 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.

Technical Specifications (Example)

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).
