Deep-qhov drilling thiab tho txawv cav yog ib hom cuab yeej nrog tig thiab txiav peev xwm kawg. Nws yog feem ntau yog ua los ntawm steel hlau SK, los yog kub ceev SKH2, SKH3 thiab lwm yam ntaub ntawv tom qab milling los yog rolling, quenching, tempering thiab kev kho cua kub. Nws yog siv los siv rau hauv cov hlau los yog lwm cov ntaub ntawv. Nws muaj ntau hom kev siv thiab yuav siv tau hauv drilling tshuab, tshuab dhos, milling tshuab, tes fais fab thiab lwm yam cuab yeej cov cav tov. Drilling kuj yog ib qho ntawm txoj haujlwm machining.
Deep-qhov drilling thiab tho txawv cav yog txheej txheem ntawm kev pub mis txias nrog cov roj kev tso tawm thiab tso chips sab hauv. Nws tuaj yeem xyaum qhov sib sib zog nqus ntawm cov khoom siv xws li carbon steel thiab hlau alloy, thiab qhov piv ntawm qhov ntev mus rau kab yuav mus txog 1: 100.
