machining chuck / expandable / 4-jaw

Use: turning, milling, grinding, shaving and inspection operations
Expansibility 0.5 to 1 mm depending on the diameter of the sleeve
Possibility to clamp worpieces with diameters ranging from 5.5 to 79.7 mm
The slotted sleeve has a collar contained within a knurled ring. This collar acts as a workstop, positioning the workpiece axially on the mandrel
The workpiece is clamped by tightening the sleeve with the knurled ring. The movement of the sleeve up the tapered arbor expands the sleeve, ensuring that the workpiece is clamped tightly.
The movement of the sleeve in relation to the tapered arbor guarantees that the workpiece is positioned against the workstop.
