There are three questions to answer to aid the correct choice of power chuck:
1. Type and model of CNC lathe.
2. Length of workpiece?
3. Outer diameter of workpiece?
4. Processing requirement?
Size Parameters
| Model/Spec | A | B | C | D | E | F | G | H |
| JHS-40" | 144 | 95 | 38 | 100 | 96 | 73 | 115.3 | 11 |
| JHS-70" | 188 | 135 | 69 | 155 | 94 | 73 | 146.4 | 11 |
| JHS-90" | 260 | 135 | 87 | 170 | 95 | 73 | 169.7 | 13 |
It is recommended to grease chucks at least twice a day in order to maximize longevity
