1, Kev tsim qauv zoo, suav nrog cov ntaub ntawv ncaj ncees, xim thiab gloss;
2, Kev sib raug zoo ntawm tag nrho qhov ntev thiab txoj hauj lwm tshwj xeeb ntawm kev sib raug zoo, uas yog lub zuag qhia tag nrho qhov tseeb thiab qhov tshwj xeeb txoj hauj lwm precision;
3, Cov khoom siv lub cev, cov khoom siv tshuaj lom neeg, cov khoom siv thermal, thiab lwm yam sib xws rau kev siv lub ntsiab, uas yog, versatility. Yog li ntawd, yog tias tag nrho cov kev sib txuas tseem ceeb hauv peb qhov no feem ntau nyuaj, nws yuav ua rau kev tsim thiab nthuav dav ntawm qhov tsis xws luag ntawm cov yas pwm handicrafts.
Qhov zoo ntawm cov pwm yas yog nyob ntawm tsis tsuas yog ntawm pwm nws tus kheej, tab sis kuj nyob ntawm seb cov khoom ua tiav nrog cov pwm no yuav dhau qhov kev xeem.
Thawj qhov pom ntawm pwm nws tus kheej yog cov khoom siv ntawm pwm. Ntau tus neeg siv khoom paub tias ua ntej muab qhov kev txiav txim rau pwm, lawv yuav tsum qhia meej cov khoom siv pwm nrog cov chaw tsim khoom. Kev xaiv cov khoom siv pwm yog qhov kev xaiv ntawm cov hlau. Kev xaiv steel yog qhov kev xaiv ntawm steel hardness thiab toughness. Rau cov pwm, qhov siab dua qhov hardness ntawm cov hlau xaiv, qhov nyuaj dua nws yog hnav thaum lub sijhawm tsim khoom, thiab lub neej ua haujlwm ntev dua. Qhov kev pab cuam lub neej ntev dua, cov khoom pwm tuaj yeem tsim tau ntau dua, uas yog kev txuag rau cov chaw tsim khoom yas. Qhov thib ob, nws yog ib qho tsim nyog los saib seb cov pwm yas puas yooj yim tawg raws li kev tsim khoom, kev tsim khoom thiab kev saib xyuas, thiab feem ntau yuav tsum tau kho. Txhua tus paub tias tej yam uas yooj yim tawg yog qhov phem tiag tiag. Tsis tas li ntawd, saib seb cov khoom tsim muaj flash, burr thiab du nto. Yog hais tias muaj flash, burr thiab unsmooth, nws yeej tsis zoo. Cov chaw tsim tshuaj molding tseem yuav tsum npaj cov neeg kom tshem tawm cov burr flash, uas yog qhov nkim sijhawm thiab cov neeg ua haujlwm thiab cov khoom siv.
