3-Jaw Large Through Hole High Speed Power Chuck

1. A power chuck is suitable for installation on a lathe machine, milling machine, or special machine to clamp workpieces.
2. A chuck with an open center through-hole allows the workpiece to be inserted into the through-hole
3. By enlarging the through-hole, larger workpieces can be inserted.
4. A 3-jaw chuck is suitable for clamping round bar workpieces, while 2-jaw and 4-jaw chucks are suitable for clamping irregular workpieces.
5. The power chuck needs to be actuated by a hydraulic rotary cylinder and a draw-bar to achieve the clamping action.
