ABSTRACT Since many factories and enterprises in the grinder was so long ago, its work has been far from modern production requirements. Therefore it is necessary to the old conventional motor control system transformation, in order to replace the conventional programmable logic controller PLC relay, thus reducing intermediate relay, so that lines are simplified to improve reliability, achieve the purpose of grinding machine automation . Firstly the old cylindrical grinder electrical system was a brief introduction, points out its shortcomings and then propose a better rehabilitation programs. The program will improve the control system hardware and software design to describe two aspects. The hardware design section details the selection of programmable logic controller PLC, I / O allocation table and the PLCs external wiring diagram of the painting; and software design from the general steps PLC program design start, and then the PLC program Design ideas and programs, some of the procedures and the ladder section of the draw. After transformation, the grinding work of safe and reliable, the system performed well, higher precision grinding; grinding operation using PLC control to achieve a grinding machine to start, stop, failure to stop, emergency stop function, and has set two process control and automation control, so you can switch the grinder according to operational requirements and flexible control mode, enabling the grinding operation of automatic control.  Electrical control system associated with the development and the development of control devices, mainly as follows: from the control, from manual to automatic control development; in control, from sin
