Abstract: In order to solve the problems of changing curve and pressure acquisition in mechanical loading system for grinding and polishing, the main factors such as pressure influencing the effect of polishing and various pressure loading research methods were researched. Research on two aspects of mechanical structure and control of hardware and software, and the pressure loading control system based on motion controller PCI1240U and USB bus technology was used.And the labview software is used to design a good interface of users and computer.So,changing curves of loading force and pressure acquisition were tested by pressure loading test platform.The results indicate that the system call realtimely monitor the pressure parameters of the loading system, realize the function of the curves of different pressure loading,and it has fast response and high reliability．Therefore, it can improve the machining efficiency of flat grinding based on the quality of the workpiece.

Key words: plane grinding and polishing; changing curve; efficiency
