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.
