ABSTRACT:
A multi-spindle drilling machine which can perform drilling and tapping using a number of spindles in such a way that by dividing the pitch circle of the holes to be worked into several divisions, all holes are machined by a number of strokes of the spindle head. The setting of the tool spindles is done within a short time by a simple arrangement with the aid of a conventional electronic calculator.
