Structure Design of Automatic Metallographic Pregrinding Table
In view of the problems such as manual pregrinding metallographic sample takes a long time,it is difficult to control the strength and grinding time,mechanical pregrinding is not fully automated,it still needs to grab the pattern by hand,and the need to manually change the sandpaper,a workbench that can directly clip the metallographic sample and automatically grind it is designed.The workbench mainly includes a test bench,automatic grinding module,automatic sandpaper module and metallographic sample scratch observation module,which can realize the automation of the whole process of metallographic sample from grasping to grinding completion,and can observe the specific condition of the sample surface after each type of sandpaper grinding,and feedback to the operator.The table can not only realize the automatic grinding of the whole metallographic sample,but also solve the problems of low efficiency of manual grinding of metallographic sample and unstable preparation quality.
