Traditional forms of hydraulic clamping system are applied in automatic machining systems of machine tool in the past,however its defects are obviously such as relatively complex speed control circuit ,large loss of pressure keeping and so on.A frequency control technology program was put forward for hydraulic clamping system.The principle,application method and the design of general speed control circuit were analyzed.The calculating and choosing method of the motor speed for the pressure keeping process was proposed.Practical application shows that the automatic clamping system with frequency control technology can simplify the circuit,make the speed control more convenience,and have positive effects on energy saving,noise reducing and cooling in the process of processing and holding pressure.
