At present, the use of small and medium-sized enterprises are traditional relay - contact control horizontal boring. Due to the complexity of the control circuit relay contact, slow, poor reliability, fault

4、diagnosis and eliminate disadvantages such as difficult, which makes the enterprise production efficiency and benefits. In view of this situation, adopting PLC for horizontal boring. The design of the machine by two electric drive systems composed 3-phase induction motor. The motor is a two-speed motor to drive into the machine and to exercise. Using the MCGS software simulation, and Control commissions MCGS (so, general System) is a set of monitoring System for fast and generating computer mo
