- **Caution**: 

### Q: What materials are best for a carriage body/frame in heavy-duty applications?
**A**: For heavy-duty machinery, cast iron or steel alloy carriage bodies provide superior strength and vibration damping. Aluminum alloy is ideal for applications requiring reduced weight while maintaining structural integrity.

### Q: How does the carriage body/frame affect cutting tool precision?
**A**: The carriage body serves as the structural foundation, ensuring stable mounting surfaces and guide rail alignment. Proper reinforcement ribs and drive mechanism interfaces minimize deflection, maintaining precise tool positioning during operation.

### Q: Can carriage bodies/frames be customized for specific machinery?
**A**: Yes, carriage bodies can be engineered with custom mounting surfaces, guide rail points, and drive interfaces to integrate seamlessly with existing machinery systems, optimizing performance and compatibility.
