Mubvunzo:

1: Tarisa michina nemidziyo, tarisa nzvimbo yekuisa yesaha blade, nezvimwe. 

2: Matambudziko nebadza resaha pacharo, kupfeka, mazino akatsemuka, mazino akatsemurwa 

Yetatu: Mamiriro ekushanda emuchina jekiseni remafuta 

China: Iyo blade yesaha inoshandiswa kuchekwa kwakaoma, kukweshera nezvinhu, uye hapana kupisa kupisa uye mhedzisiro yekuzora, zvichikonzera kukuvadzwa kune blade yesaha uye burrs pane yakachekwa pamusoro peiyo workpiece. 

Solution:

1. Kana blade yesaha isina kupinza kana kuchekwa, geda nenguva 

2. Iyo mafuta jekiseni system yemuchina inofanirwa kugadziriswa kudzivirira kuomeswa kwekucheka kwesaha blade. Inokurudzirwa kushandisa nyanzvi yekucheka mvura kana mafuta ekucheka.
