KEM Series includes a manually-operated expanding mandrel actuator incorporating a precision-ground 38mm diameter spigot for mounting in collet or jaw chucks. These models utilise the same precision mandrels, expanding sleeves and locators as our CNC Expanding Mandrels. They are side-actuated with an included square-drive key so that they can accommodate parts with blind bores as well as those with thru-holes. Precision-ground for high accuracy in squarenesss and concentricity, If higher accuracy is needed the mandrel can be clocked-in once the unit is gripped in a chuck.
