KERVIVAR technology is committed to serving the school to develop comprehensive and practical integrated teaching equipment, and has long been committed to the development and manufacturing of NC training equipment. It has a deeper understanding of the problems existing in NC teaching, and has a more in-depth research on the teaching, training and curriculum reform of electromechanical NC majors. In order to support the state's proposal to vigorously promote the reform and innovation of secondary and higher vocational education, comprehensively improve the school running quality, and meet the urgent needs of the NC technology vocational education market, the company has developed a new concept of "NC machine tool theory practice integration classroom". This scheme is a teaching and training environment for NC machining vocational education in various engineering colleges, They are helping colleges and universities to cultivate senior skilled vocational and technical talents who meet the needs of modern manufacturing industry. "CNC machine tool theory practice integration classroom" uses network technology to help the school establish a theory practice integration teaching environment, solve the theoretical teaching of the two core courses of NC turning programming and operation and NC Milling Programming and operation, integrate theoretical learning and practical learning, and strengthen the sense of experience and interaction in the teaching process, Build the framework of quality and skill training in the whole process, so as to realize the integration of theory and practice, teaching, learning and doing; Integration of time, place, content and teachers; Theory and practice are closely combined, support and promote each other, which provides a guarantee for the optimization of teaching process.

2 construction scheme of NC machine tool theory practice integration classroom 2.1 construction of innovative teaching environment integrating theory and Practice The standard configuration of NC machine tool physics and practice integration classroom includes 20 multi-system student computers (cnc-9500n), 1 multi-system teacher computer (cnc-9450n), 1 multi-mode small desktop NC lathe (cnc-210s), 1 multi-mode small desktop NC milling machine (cnc-150a), intelligent control center (multimedia teaching software, multimedia podium, central controller and monitoring computer), Interactive demonstration system (projector, electronic whiteboard), visual processing core (network HD camera, Gigabit Ethernet switch, network hard disk video recorder), auditory processing core (power amplifier, wireless microphone, speaker), other supporting facilities (network switch, single-phase high-precision voltage regulator), etc. The whole classroom is connected into a whole through the network to realize the functions of data transmission and remote control, so that the theoretical knowledge and practical teaching are integrated and seamlessly connected with each other.
