焊接教学技能训练,常需开坡口进行操作。其中,30°坡口应用广泛,本文作者根据当前许多学校坡口加工方法,结合多年一线校企实践经历,成功试验出一种安全、高效、稳定、优质的30°角坡口加工工艺方法——数控锯床加工。该方法一次成型加工30°坡口钢板,实用性强,可操作性高,特别在中高职焊接专业中具有极大的推广应用价值。 Welding teaching skills training, often need to open the groove to operate. Among them, the 30 ° bevel is widely used. According to the current many school beveling methods, combined with years of first-line school-enterprise experience, the author successfully tested a safe, efficient, stable and high-quality 30 ° bevel processing method - - CNC sawing machine processing. The method forms a 30 ° bevel steel plate at a time, has strong practicability and operability, and has great promotion and application value especially in the welding profession of the middle and high vocational schools.
