2. Nekuda kwekusava nechokwadi kwemutengo wepfuti yekuputika muchina, mushure memakore ekuvandudza, iyo yakajairwa bara kupfura michina yakagadzira mutengo wakabatana. Musiyano wenguva pakati pekutenga nekutenga kwevatengi hauna kukura, asi mhando yechigadzirwa inofanira kusimbiswa kutanga.
Kune isiri-yakajairwa yakagadzirirwa kupfura michina, pane zvinhu zvakawanda zvisina chokwadi senge huwandu hweanopfura mabhuru, kubvisa guruva mweya vhoriyamu, uye saizi yemukamuri, saka mutengo hauna kubatana.
3. Chigadzirwa chehunhu, kupfura blasting muchina chigadzirwa chemhando inonyanya kubata zvinotevera zvinhu: (1) mhando yezvinhu zvakagadzirwa, senge hukobvu hwesimbi simbi, (2) maitiro ekugadzira, (3) kupfura blasting yekuchenesa mashandiro, ayo anogona kuve inonzwisisika kwazvo mumunda kuti uone, kana vatengi vatenga, vanogona kutarisa yekuchenesa maitiro epfuti yekuputika muchina ipapo kuti vaone kutaridzika kwekucheneswa workpiece.
