实习心得2(国外英文资料) Internship experience The purpose of an internship Through in heavy electric appliance co., LTD. Xinxiang east by practice, we can make contact in practice some of the actual work associated with this professional training and exercise we learned the integrated use of the basic theory, basic skills and professional knowledge to analyze and solve practical problems independently, combine the theory and practice, improve our actual beginning ability, for the future we lay a certain foundation to be going to work after graduation. Second, the content of the internship 1 gauges are used in machine processing for the percentage of the meter and micrometers Before using, check the flexibility of measuring rod activity. Gently push the measuring rod, the movement of the measuring rod inside the sleeve to be flexible, no rolling card phenomenon, and every time to relax, Pointers can return to the original scale. When measuring, do not make the measuring stick more than its measuring range; Dont make the measuring head bump into the parts; Dont make the dial indicator and dial gauge by severe vibration and impact, also dont push the parts force into the measuring head, lest damage the dial indicator and part of the dial indicator and loss of accuracy. Therefore, it is wrong to measure rough or marked parts with a percentage table. When using a percentage form to correct or measure parts, the measuring rod shall have a certain initial measuring force. In measuring head when in contact with the workpiece surface, the measuring rod should be 0.3 ~ 1 mm compression (dial gauge can be a little bit small, with a 0.1 mm), turn around the half circle pointer, and then turn table, make the dial zero moment I aligned pointer. Gently pull the round head of the measuring rod, pull up and relax a few times and check for any change in the zero position indicated by the pointer. When the null stability of the pointer is stabilized, the work of measuring or correcting the p
