Uma kuqhathaniswa nekhanda elivamile eliyisicefe, uhlobo olusha lunezinzuzo ezilandelayo:
1, Umhlahlandlela nge-roller, ngokusekelwa kwamaphuzu amaningi kanye nokusebenza komhlahlandlela okuzinzile.
I-2,Ukuxhumana kwephuzu phakathi kwerola nodonga lwangaphakathi lwe-workpiece kunciphisa ukungqubuzana futhi kunwebe impilo yokusebenzisa;okubaluleke kakhulu, igwema inkinga yokushintsha njalo iphedi yomhlahlandlela.
3, Ukukhiqiza kungandiswa ngokuphindwe kabili.
4, Usayizi ungalungiswa ku-5 mm, awudingi ukushintshwa noma yiziphi izingxenye, ngakho-ke ukusebenza kulula kakhulu futhi kusindisa isikhathi.
I-roller ithatha indinganiso kazwelonke, kulula kakhulu ukuyithola ngentengo efanelekile emakethe, izindleko zokusebenzisa ziphansi.
Uhlobo olusha lwekhanda eliyisicefe lihlolwa ngokuphindaphindiwe, linokusebenza okuzinzile futhi lizuza idumela elihle kumsebenzisi.
