Beschreibung
Zusammenfassung:	A headstock centre 6 and a tailstock centre 7 support a workpiece 8. A tool head 3 and a head 4 with deforming rollers 5 spaced equidistantly apart along a circumference are consecutively arranged in a housing 2 fitted on the carriage 1 of a machine tool. A length of the tailstock centre 7 contiguous in operation end-to-end with the workpiece 8 serves as a guide for the rollers 5, being given a diameter substantially equal to the diameter to which the rollers 5 are set, and its end next to the workpiece has a chamfer or groove to accommodate the point of the tool 9 in a position preparatory to machining. The centre 7 may have a centreing cone 32 engaging a smaller diameter end part of the workpiece 8. The axial holding pressure is produced by a hydraulic cylinder 47. The headstock and tailstock may have flexible portions in their centres to allow lateral workpiece movement for high precision machinery.
