b) to be secured to a workpiece (P). The device is applicable to double-sided clamping of workpieces (P) with a view to treating them or to working on them.
The invention relates to a machining head (1) for a multi‑axis machining centre, the head comprising a cradle (3) that can be rotated about an axis (B) with respect to a workpiece, and a tool‑holding arbour (4) mounted on the cradle and designed to turn a tool about an axis of rotation (R) of the tool, the machining head being characterized in that the arbour is mounted with the ability to effect a translational movement with respect to the cradle along the axis of rotation of the tool. The invention also relates to a machining centre for working along at least one axis, and preferably along several axes, the machining centre comprising: • a machining head (1) as described hereinabove, mounted to be able to rotate (axis B) with respect to the support (8), • a means (2, 7) for rotating (axis C) the support (8) with respect to a supporting structure, • a bed on which to hold a workpiece in position, and • a means (2) for driving the motion • a means for driving said bed in motion with respect to the supporting structure. Application to the five‑axis polishing of hard materials such as granite, marble, concrete, notably in the field of headstones, decoration, building, etc.
