A device for machining a workpiece comprises two or more jacks fastened on a plate carrying tool holders arranged around and centered on a mandrel spindle carrying the workpiece, the tool holders bearing on packing inserts interposed between adjacent tool holders and secured to the plate. The position of the tools in the tool holders is controlled by abutment of the tool holders on the packing inserts, the thickness of which determines the machined diameter of the workpiece. |
