在生产防锈纸过程中要把生产出来的防锈纸在实验室进行甄别试验,通常用50×25×3～4毫米各种金属试片,每次试验前要把旧试片磨光涂除锈。磨光试片是件很麻烦费力的工作,每人每天最多磨20片,而且手指都磨红、磨痛。我们仿人指压在水砂纸上磨片方式,试制了一台磨片机,节约了不少人力和时间。磨片机是利用运动的相对性,试片不动,砂纸来回运动。砂纸放在滑块上由电动机带动作来 Antirust paper produced in the production of rust-proof paper should be produced in the laboratory screening test, usually with 50 × 25 × 3 ~ 4 mm of various metal test strips, each test before the old test piece should be polished Rust Polished test piece is a very troublesome work, grinding up to 20 per person per day, and fingers are red, grind. We imitate human finger pressure on the water sandpaper grinding method, a trial of a grinding machine, saving a lot of manpower and time. Grinding machine is the use of the relative movement, specimen does not move, sandpaper back and forth movement. Sandpaper on the slider driven by the motor
