Graphite End Mill Helix Angle Design: Optimizing Cutting Performance in CNC Graphite Machining
During a high-precision graphite electrode machining project, a customer ran into a recurring issue. The process ran smoothly for the first few hours using standard graphite end mills. However, as cutting depth increased, slight edge chipping appeared, dust generation spiked, and tool life dropped sharply. The team initially adjusted spindle speed, feed rate, and depth […]
