Understanding CNC Hard Material Machining

Processing hard materials like titanium, hardened steel, or Inconel requires specialized CNC machining techniques. At AOOM, we employ advanced tooling strategies and rigid machine setups to maintain precision while minimizing tool wear. The key challenges include heat generation, excessive tool pressure, and achieving desired surface finishes.

Critical Techniques for Hard Material CNC Machining

1. Tool selection: We use carbide or CBN tools with specialized coatings (TiAlN, diamond-like carbon) that withstand high temperatures.
2. Optimized cutting parameters: Reduced feed rates with higher spindle speeds prevent work hardening.
3. Rigid fixturing: Our 5-axis machines feature vibration-dampening systems for stability during heavy cuts.
4. Coolant management: Through-tool coolant delivery prevents thermal deformation of workpieces.
