Ground VS. Rolled Ball Screw
| Comparison Items | Ground | Rolled |
| Manufacturing Process | The process involves machining using a screed, typically followed by finishing after heat treatment. This results in high machining accuracy and a smooth surface finish. | Another method utilizes cold rolling forming, where round bar material is extruded into threads using a rotating die. This eliminates the need for material cutting, leading to high processing efficiency. |
| Accuracy | Reaching C0-C5 level, with extremely small lead error, suitable for high-precision requirements. | C7 Grade |
| Operational Quality | Extremely smooth surface, low friction, and quiet operation. | Polished surface ensures smooth operation. |
| Mechanical Properties | The thread has high concentricity with the shaft, and the backlash is small or can be eliminated through preloading, making it suitable for high repeatability and positioning accuracy requirements. | The rolling process induces plastic deformation, resulting in higher thread surface hardness and strength, and superior fatigue resistance compared to grinding grades. |
| Delivery Time | Customized production results in longer delivery times. | Standardized production results in shorter delivery times. |
| Applicable Scenarios | High-precision CNC machine tools, semiconductor equipment, aerospace, medical devices, and other applications requiring high positioning accuracy and repeatability. | Industrial automation, logistics equipment, industrial machinery, etc. |
