摘要
职业学校钳工实习教学的钻孔是钳工专业一项重要基本操作技能,要求进行系统的技能和技巧训练,掌握加工要求较高的孔及位置精度的方法。但由于钻孔中的累积误差很难完全消除,钻孔的位置精度也就很难保证,因此如何消除或减少钻孔的误差是钳工实习教学中的难点和终点。文章从钻孔误差产生的原因和防止方法两个角度出发,探索了钳工实习教学中,如何消除或减少钻孔误差的教育教学生产实践。
The vocational schools fitters teaching the drilling fitter professional is an important basic skills, system skills and skills training, to master the method of processing require a higher hole position accuracy. Difficult to complete- ly eliminate the accumulated error in the drilling, the drilling position accuracy will be difficult to ensure, so how to elim- inate or reduce the error of drilling is the Fitters teaching difficulties and the end. Article from the borehole error causes and prevention of two angles, and explore the Fitters teaching, and how to eliminate or reduce drilling error teaching pro- duction practices.
