3JM Three-Jaw Heavy-Duty Power Chuck

The three-jaw heavy-duty power chuck can simultaneously clamp the workpiece radially and axially pull it back, ensuring the workpiece stays tightly against the reference surface without lifting.
the three-jaw power chuck can be used with leak detection to confirm axial positioning, making it ideal for machining that requires precise length.
the heavy-duty chuck used cylindrical sliding structure ensures high clamping precision and durability, suitable for heavy cutting applications.
