Superalloy Cotter-Pin Hole Drilling

Workpiece

  • GH4169 Superalloy
  • HV560

Challenges

  • Low machining efficiency with bench drill
  • Severe burrs with size up to 1.206mm
  • Manual deburring necessary

Benefits

  • Hole wall quality improved
  • Burrs reduced by 91.6%, from 1.206mm to 0.101mm
  • Cost saving from replacing manual operation with CNC machining

Workpiece

Benefits
