A method for producing a hydraulic block of a slip-controlled hydraulic non-muscular-energy vehicle brake system. For the milling operation, the hydraulic block is clamped in two setups and a pump bore, into which the hydraulic block is clamped in the second setup, is produced in the hydraulic block in the first setup, thereby making it possible to machine five sides of the hydraulic block in the second setup free of clamping arrangement. Also described is a related hydraulic block.
