Txoj Cai Ua Haujlwm ntawm Miniature Pob Screws

Cov pob me me ua tiav siab -txoj kab ncaj nraim los ntawm kev siv lub voj voog dov ntawm cov khoom nruab nrab ntawm cov ntsia hlau thiab cov txiv ntoo. Cov khoom tseem ceeb muaj xws li cov ntsia hlau ncej, txiv ntseej, pob, thiab rov qab ua haujlwm. Nws hloov cov kev sib hloov mus rau hauv cov lus tsa suab los ntawm kev dov ntawm cov khoom nyob rau hauv cov threaded grooves, ua tiav kev sib txhuam coefficient tsawg li 0.001-0.003 thiab kev sib kis tau zoo tshaj 90%. Cov txheej txheem tseem ceeb suav nrog: cov qauv ua ntej txhawm rau tshem tawm cov backlash, kev sib tsoo kom paub tseeb qhov tseeb ntawm ± 5μm / m, kev siv chromium{11}}molybdenum alloy steel nrog hardness ntawm HRC58-62, thiab cov hlau lead ntau ntawm 0.5-5mm. Qhov kev tsim no tshwj xeeb yog tsim rau cov khoom siv precision uas xav tau micron-theem qhov tseeb, xws li kev tsim khoom semiconductor thiab cov cuab yeej kho mob.
