ABSTRACT:
A drilling machine comprises a ram movable up and down on a carriage slidably mounted on a horizontal crossrail. A toolhead is mounted on the bottom end of the ram for pivotal movement about a horizontal axis at right angles with the crossrail and is pivoted to a desired angular position by a first drive shaft within the ram via bevel gearing. Rotatably mounted in the toolhead for rotation about an axis lying in a vertical plane is a toolholder which rigidly supports a drill and which is driven from a second drive shaft within the ram via bevel gearings. Preferably, the machine further comprises a rack-and-pinion mechanism driven from the second drive shaft for securely but releasably locking a turning tool at the bottom end of the ram, so that the machine can be used also for turning operation as a workpiece is rotated on a turntable. This turntable is of course held stationary during drilling operation.
