钳工在机械制造及机械维修中有着特殊的、不可取代的作用。钳工的劳动强度大,生产效率低,对工人技术水平要求较高,锉削、锯割又是钳工专业中重要的操作技能,也是学生训练的重点和难点,往往需要花大量的时间去练习而又不易掌握。可以改进锉刀握柄的方法,计算锉削余量(进给量)的次数,锯削时改变锯弓的握法,提高练习效果,使学生训练中事半功倍。 Fitter in the machinery manufacturing and machinery maintenance has a special, irreplaceable role. Fitter’s labor-intensive, low productivity, higher requirements on the technical level of workers, filing, sawing is fitter in the important operating skills, but also the focus and difficulty of student training, often takes a lot of time to practice Not easy to grasp. You can improve the method of the file handle, calculate the number of filing margin (feed), change the grip of the saw bow when sawing to improve the practice effect, so that students work more efficiently.
