Motorized combination chucks, widely used on oil country lathes for high efficiency and reliable clampings. These chucks are used in pairs with the front chuck firmly clamping the workpieces and the rear chuck maintaining the workpiece stable rotation without swinging. Gear sets are equipped on back of the chucks to drive them with an independent motor mounted on the machine headstock's corner.
Ready models of these chucks for SMTCL made oil country lathes. For lathes under other brands, combination chucks can be custom made as long as the relevant features matching the chucks on the lathe headstock can be provided.
