ABSTRACT:
A method of displacing or feeding the honing tool of a honing machine dur long stroke honing when machining workpiece bores. Rapid displacement feeding or and subsequent machining displacement or stock removal feeding are effected with only a single motor employed in common for different operation, which is controlled in such a way that during rapid feeding or displacement it operates at high speed and low limiting angular momentum or torque limit. Due to the low angular momentum or torque limit during rapid displacement, the speed is rapidly reduced when the honing stones come to rest agianst the bore wall. The control mechanism thereupon reverses the single motor, returns the honing stones by a small amount, and changes over to the machining or stock removal feeding process, which is accomplished at low motor speed and high limiting angular momentum. When a pretermined finished size has been achieved, a displacement control mechanism returns the honing tool to its starting position. The invention covers a method for automatic displacement control of a honing machine, as well as an apparatus for carrying out this method.
