Lubrication of Ball Screw
| Lubrication method | Check Interval | Inspection items | Refill or Replacement Interval |
| Automatic intermittent oil supply | Weekly | Oil volume, oil pollution, etc. | Supplement at each inspection |
| Grease | Initial use 2-3 months | Contamination, foreign matter, etc. | Usually replenished once a year |
| Oil bath | Before starting work every day | Oil surface | Replenish during daily inspection |
Cold Rolling VS Grinding
- Cold rolling: A milling process that uses extrusion (plastic deformation) between two rollers to roll the thread into a thread shape in one go. It has high processing efficiency, fast delivery and low price. Generally, it can process screws with c7 and c10 precision. It is used for general precision equipment.
- Grinding: The ball screw is ground by a high-precision thread grinder. Generally, it can process c5, c3, c0 precision screws. It is suitable for precision CNC equipment. Such as CNC milling machines, CNC lathes, machining centers, etc.
