A deep boring machine is described which has a spindle unit (2) with a horizontal spindle shaft (40) for receiving a boring tool (50). The spindle unit is horizontally displaceable on a machine bed (1) and is driven by a spindle drive mechanism (2). The boring head (6) is guided, upon initial boring of the workpiece (11), in a jig bushing (7) which is disposed in a jig bushing holder (13). The jig bushing holder (13) is displaceable on a guide (25, 26) in the direction of the spindle shaft (40). The guide (25, 26) is disposed above and offset parallel (h1, h2) from the spindle shaft (40) and extends at least partly beyond the machine bed (1). A workpiece clamping table (19) is disposed adjoining the machine bed (1) and is adjustable independently thereof. |
