CNC Ballscrew FFA series operating principle
Converts rotary motion into linear motion, based on the interaction of balls and threads
Heat Treatment Hardness
| Part name | Heat treatment | Hardness (HRC) |
| Screw | Induction heating, quenching | 58-62 |
| Nut | Carburizing, quenching, tempering | 60-62 |
| Ball | / | 62-65 |
Routine examination
1. Check the amount of runout of the shaft head
2. Check the amount of movement of the screw support and the mounting platform
3. Check the relative amount of movement between the working platform and the nut seat
4. Check the relative amount of movement between the nut seat and the nut flange
Advanced processing technology
Quenching
The heated FFA series ballscrew is quickly immersed in a quenching medium (such as oil or water) to cool it quickly.
Straightening
Based on the measurement results, adjust the support points or fixed points of the ballscrew to gradually correct its straightness.
Finished product inspection
Check the roundness of the ballscrew to ensure that it does not produce significant deviations when rotating.
