PSK - 4-Jaw Scroll Chuck

4-Jaw Design: This manual chuck has four jaws that allow for both radial and axial adjustment. Unlike 3-jaw chucks, which are more common, a 4-jaw chuck provides better precision and can hold irregularly shaped workpieces. Each jaw can be adjusted independently, providing more flexibility in securing the workpiece.
Powerful Type: this 4-Jaw chuck is designed for heavy-duty applications, capable of withstanding high clamping forces, making it suitable for larger, tougher workpieces and more demanding operations.
Scroll Mechanism: The scroll mechanism refers to the internal helical gear that simultaneously moves all four jaws when the chuck is turned. This mechanism ensures that the jaws close or open uniformly and smoothly, reducing the effort required to clamp the workpiece.
Precision and Stability: The PSK 4-jaw chuck is often chosen for its precision, especially in turning operations where part concentricity is critical.
