Why Choose 6CNC for CNC Machined Frames
CNC Machined Frames from solid billet offer superior strength, vibration damping, and dimensional stability compared to welded or sheet metal frames. We excel at producing large-format precision frames with:
- Large machining envelopes for oversized frames
- Excellent flatness and parallelism across wide surfaces
- Precise hole patterns, slots, and mounting features
- Integrated ribs, bosses, and weight-reduction pockets
- Multi-setup or 5-axis machining for complex geometries
Technical Advantages:
- 5-Axis and large-travel CNC milling for complex frame structures
- Precision surface grinding for superior flatness (up to 0.01 mm/m)
- Stress-relief processes to maintain long-term stability
- Threaded holes, dowel pin holes, and alignment features with high accuracy
- Professional DFM feedback to optimize strength-to-weight ratio
