Abstract：With the gradual maturation of the "internet plus education" mode， blended teaching is gradually recognized by the CNC professional teachers in technical colleges and universities. Teachers are beginning to explore the online + offline teaching mode to enhance the operation ability of students numerical control equipment. Teachers majoring in NC lathe work in technical colleges should design a hybrid teaching scheme in combination with students' comprehensive quality， focus on the operation skills of NC equipment， use micro courses to explain the programming and operation difficulties of NC machine tools， milling machines and boring machines， use rain classroom to carry out online teaching， guide students to carry out online simulation operation， optimize the traditional NC lathe work training methods， systematically explain the post skills of NC lathe workers for students， and improve the employment competitiveness of NC majors in technical colleges.

Key words：technical colleges， CNC lathe workers， hybrid teaching， application strategy
