摘要：
In a process and device for calibrating throttle bores, in particular in injection valves for internal combustion engines, by means of hydroerosive machining of the throttle bore with a suspension, the actual through flow is compared to a predetermined reference through flow. When the actual—and reference through flows coincide, the hydroerosive machining is brought to an end. On the outflow side of the throttle bore, a counterpressure is built up, which prevents the cavitation of the fluid.
