Abstract: With the continuous evolution of industrial demand under the background of new engineering, modern education faces the challenge of cultivating engineering and scientific and technological talents with more innovative ability and practical ability. The research is committed to building and applying the comprehensive practical teaching platform of“Three integrations to promote education”to meet the needs of mechanical professional talent training under the background of new engineering. Through the deep integration of industry-education, creative education and competition teaching modes, students'comprehensive ability is improved. This will not only provide a reference for the transformation and development of application-oriented undergraduate universities, but also provide strong support for the talent training of the machinery industry.
