Tig yog ib qho ntawm cov txheej txheem machining feem ntau; yooj yim muab, nws koom nrog kev sib hloov ntawm lub workpiece thiab txav ntawm cov cuab yeej txiav kom tshem tawm cov khoom siv ntau dhau thiab ua kom zoo li ib feem. Nws yog feem ntau ua rau ntawm lub tshuab dhos thiab yog tsim rau machining ntau qhov chaw ntawm kiv puag ncig, xws li shafts, discs, thiab tes tsho.
Raws li lawv cov kev npaj siv thiab kev tsim qauv, tshuab dhos feem ntau yog categorized rau hauv kab rov tav lathes (xws li hauv pem teb-hom tshuab dhos), ntsug tshuab dhos, turret lathes, ib leeg- spindle automatic lathes, multi- spindle automatic thiab semi- tshuab dhos tshuab, tshuab dhos tshuab tshuab dhos, thiab ntau yam tshwj xeeb tshuab dhos-xws li cov uas tsim los rau camshafts, crankshafts, railway log, thiab relieving ua hauj lwm. Ntawm cov no, kab rov tav tshuab dhos yog siv dav tshaj plaws. Kab rov tav lathes tuaj yeem ua tiav qhov ntev ntev xws li IT8 txog IT7 thiab nto roughness (Ra) qhov tseem ceeb tsawg li 1.6 μm.
Kev siv tshuab computer dav dav hauv kev lag luam tshuab cuab yeej tau ua rau muaj qhov tshwm sim ntawm cov khoom mechatronic xws li CNC lathes thiab cov chaw xa khoom. Kab rov tav CNC tshuab dhos, tshwj xeeb, tuaj yeem muab faib ntxiv los ntawm kev ua haujlwm hauv kev lag luam - qauv CNC lathes, txheem CNC tshuab dhos, thiab cov chaw xa khoom. Surface profile raug.
