3 Qhov laj thawj tseem ceeb rau Wood Warping
Thaum siv cov saw saw hniav los txiav cov cav, ntoo warping tuaj yeem tshwm sim rau ntau yam, tshwj xeeb tshaj yog tias cov cav ntoo loj dua. Hauv tsab xov xwm no, peb yuav tham txog dab tsi yuav ua rau sawn lumber rau warp thiab peb yuav tsum ua li cas txog nws.
Ua ntej, yog hais tias ntoo yog warping vim lub band saw: peb yuav tsum tau xyuas cov nram qab no ob feem ntawm lub band pom: lub tensioner thiab saw log.
Yog tias lub tshuab tensioning tsis ua haujlwm zoo thiab lub teeb dhau, nws yuav ua rau cov ntoo buckle. Yog tias qhov no tshwm sim, ntxiv qhov hnyav thiab kho qhov tensioner tuaj yeem daws qhov teeb meem.
Yog tias tsis muaj teeb meem nrog cov cuab yeej tensioning, ces peb yuav tsum tau mus rau cov kauj ruam tom ntej thiab xyuas qhov hnav ntawm cov saw log rim nto ntawm band saw tshuab. Yog hais tias lub saw log txoj kab uas hla tsis sib xws vim hnav, ntoo kuj yuav warp. Txoj kev kho no yooj yim heev, tsuas yog zom cov saw log rim nto. cov
Yog tias peb txheeb xyuas lub tshuab tensioner thiab pom lub log thiab pom tsis muaj teeb meem, ces peb yuav tsum xav txog seb lub saw sawb puas ua rau cov ntoo ua kom tawv.
Thaum xav txog kev khoov ntawm cov ntoo tshwm sim los ntawm cov sawb, koj tuaj yeem tshawb xyuas los ntawm ob lub ntsiab lus hauv qab no:
Ua ntej, cov hniav zoo nkauj ntawm cov saw hniav tsis raug lossis cov hniav chamber me dhau lawm, thiab cov hniav saws yog nqaim thiab tsis ncaj, uas yuav ua rau cov ntoo khoov. Nyob rau hauv rooj plaub no, nws yog ib qho tsim nyog yuav tsum tau hloov kho cov hniav ntawm cov saw hniav, ua kom cov hniav sib tsoo, los yog hloov cov saw hniav nrog ib txoj kab uas hla loj dua. cov
Qhov thib ob yog tias band saw hniav nro tsis sib npaug. Lub sawb yuav xoob thaum lub sijhawm ua haujlwm, uas tuaj yeem ua rau cov ntoo saws khoov. Nyob rau hauv rooj plaub no, tsuas yog kho cov saw hniav nro mus rau qhov tsim nyog.
Tom qab teeb meem nrog lub tshuab thiab pom cov hniav tau raug txiav tawm, warping ntawm cov ntoo vim kev ua haujlwm yuav tsum tau txiav txim siab.
Ua ntej, yog tias qhov pub ceev nrawm dhau thiab tsis sib xws thaum lub sijhawm ua haujlwm, nws tseem yuav ua rau cov ntoo saws tawm. Yog li ntawd, thaum sawing ntoo, pub yuav tsum nyob ruaj khov thiab pub yuav tsum qeeb thaum ntsib cov pob. cov
Qhov thib ob, yog tias cov saw log thiab cov hniav yog stained nrog resin sawdust, ua rau cov hlua saw hniav rau lub sijhawm ua haujlwm, ntoo kuj tuaj yeem khoov. Yog hais tias lub saw log thiab saw hniav yog stained nrog txawv teb chaws, lawv yuav tsum tau muab tshem tawm tam sim ntawd. cov
Thaum kawg, cov saw saw hniav nrog cov hniav dull lossis cov hniav tsis zoo tuaj yeem ua rau cov ntoo raug txiav mus rau warp. Yog hais tias cov saw hniav yog npub, lawv yuav tsum tau muab sharpened nyob rau hauv lub sij hawm, thiab lub sij hawm ua hauj lwm ntawm lub band sawb yuav tsum tau teem kom tsim nyog raws li lub hardness ntawm ntoo kom tsis txhob siv nws ntev heev; tib lub sijhawm, tsis txhob siv cov saw hlau tsis zoo rau kev txiav.
Yog tias koj xav tau cov hniav zoo nkauj bandsaw, koj tuaj yeem tiv tauj peb txhua lub sijhawm. Seb nws yog alloy saw hniav, Stellite saw hniav, bimetal saw hniav los yog hardened saw hniav, peb muaj peev xwm muab tau zoo thiab txhawb customization.
