Macheka ozizira amagwiritsa ntchito mpeni wozungulira podula zitsulo. Zinali ndi dzina lake chifukwa chakuti machekawo amatengera kutentha m’tsambalo m’malo molowa m’chinthu chimene akudulidwacho, motero amasiya chinthu chodulidwacho chizizira mosiyana ndi macheka onyezimira, amene amatenthetsa tsambalo ndi chinthu chodulidwacho.

Nthawi zambiri zitsulo zothamanga kwambiri (HSS) kapena masamba ozungulira ozungulira a tungsten carbide amagwiritsidwa ntchito pamachekawa. Ili ndi mota yamagetsi ndi gawo lochepetsera zida kuti liwongolere kuthamanga kwa liwiro la macheka ndikusunga torque yosalekeza, zomwe zimawonjezera mphamvu zake. Macheka ozizira amatulutsa phokoso lochepa ndipo palibe zopsereza, fumbi kapena kusinthika. Zida zomwe zimayenera kudulidwa zimamangidwa mwamakina kuti zitsimikizike kuti zadulidwa bwino komanso kupewa kusuntha. Macheka ozizira amagwiritsidwa ntchito ndi makina oziziritsira madzi osefukira omwe amasunga mano a tsamba la macheka azizirira komanso opaka mafuta.

Kusankha tsamba loyenera lozizira ndikofunikira kwambiri kuti mudulidwe bwino. Pali macheka apadera odula nkhuni kapena zitsulo mapepala ndi mapaipi. Nawa malangizo omwe muyenera kukumbukira pogula macheka ozizira.

Blade Material:Pali mitundu itatu yaozizira macheka tsambamakamaka kuphatikizapo carbon steel, high speed steel (HSS) ndi tungsten carbide nsonga. Zomera za kaboni zimatengedwa kuti ndizochuma kwambiri kuposa zonse ndipo zimakondedwa pantchito zambiri zodula. Komabe masamba a HSS ndi olimba komanso otalika kuposa chitsulo cha kaboni pomwe masamba a Tungsten carbide ali ndi liwiro lothamanga kwambiri komanso nthawi yamoyo yamitundu itatuyi.

Makulidwe:Kukhuthala kwa macheka ozizira kumayenderana ndi kukula kwa gudumu lokwera la macheka. Kwa gudumu laling'ono la mainchesi 6, mungafunike tsamba la mainchesi 0.014. Thinner tsamba kwambiri adzakhala moyo wa tsamba. Onetsetsani kuti mwapeza kukula koyenera kwa tsambalo kuchokera m'mabuku ogwiritsira ntchito kapena funsani wopereka katundu wanu kuti mudziwe zambiri zofunikazi.

Kapangidwe ka Mano:Ndikwabwino kusankha mapangidwe amtundu wanthawi zonse azinthu zosalimba komanso kudula kwanthawi zonse. Ma skip-tooth blade amagwiritsidwa ntchito podula bwino komanso mwachangu pazinthu zazikulu. Magawo a mbedza amagwiritsidwa ntchito podula zitsulo zopyapyala ngati aluminiyamu.

Muyezo:Amayezedwa mu unit of teeth pa inchi (TPI). TPI yabwino kwambiri ili pakati pa 6 mpaka 12, kutengera zomwe zimagwiritsidwa ntchito. Ngakhale zida zofewa ngati aluminiyamu zimafunikira masamba abwino okhala ndi TPI yotalikirapo, zida zokhuthala zimafuna masamba olimba okhala ndi mawu otsika.

Mapangidwe a Mano:Masamba okhazikika amakhala ndi mano amodzi osinthasintha mbali zonse za tsamba. Masambawa amatsimikizira kudulidwa kofanana kwambiri ndipo ndi koyenera kudula ma curve ndi ma contours. Mitundu ya wavy yokhala ndi mano ambiri oyandikana imayikidwa mbali imodzi ya tsamba, yomwe imapanga mawonekedwe a mafunde ndi gulu lotsatira la mano omwe ali mbali ina ndi yotalika. Mitundu ya wavy imagwiritsidwa ntchito kwambiri pazinthu zosalimba.
