Boberry

CNC Milling Machined Parts

  • High Geometric Accuracy: Outstanding symmetry, straightness, verticality, and flatness for accurate assembly.
  • Functional Feature Machining: Able to produce key grooves, T-type grooves, dovetail grooves and other slot forms.
  • Toothed Component Production: Processes slip-tooth parts such as gears, spline shafts and sprocket wheels.
  • Spiral Surface Processing: Capable of threads and thread grooves, including special spiral profiles.
  • Multi-Operation Efficiency: Milling, lead plugging and boring operations can be combined to reduce cycle time.
