Umatshini wokucheba ngumatshini osebenzisa incakuba enye ukwenza isindululo somgca esibuyisela ukusika ipleyiti xa ithelekiswa nenye incakuba.Ngokuhambisa i-blade ephezulu kunye ne-blade esezantsi eqingqiweyo, i-gap ye-blade efanelekileyo isetyenziselwa ukusebenzisa amandla okucheba kwiipleyiti zetsimbi ezinobunzima obuhlukeneyo ukuze baphule kwaye bahlule iipleyiti ngokobukhulu obufunekayo.Umatshini wokucheba ngomnye woomatshini bokubumba, umsebenzi wawo ophambili lishishini lokulungisa isinyithi.Iimveliso zisetyenziswa kakhulu kwimveliso yesinyithi, i-aviation, imboni yokukhanya, isinyithi, ishishini lemichiza, ukwakhiwa, ulwandle, iimoto, amandla ombane, izixhobo zombane, ukuhombisa kunye namanye amashishini ukubonelela ngoomatshini abakhethekileyo kunye neeseti ezipheleleyo zezixhobo.
