In known deep-hole drilling machines, the undesirable situation arises, in the case of large drilling depths, that the boring bar, which becomes increasingly softer with increasing drilling depth, sags and starts to vibrate, so that the boring bar must be supported. This should, however, be possible at suitable spacings in the simplest possible manner and without interrupting the working process. For this purpose, it is envisaged that at least one guide bush for supporting the boring bar in a workpiece bore is provided on the boring bar, the guide bush being associated in a coaxial arrangement with a clamping ring of a ringe thickness which makes self-jamming tilting on the boring bar possible, and which clamping ring is pivotally coupled at one peripheral point to the guide bush to permit a small radial movement and has an external diameter smaller than that of the guide bush, and that at least one disengageable stopping device for a guide bush is provided within the coolant feed device. |
