Iiprofayili zokugquma ezibunjiweyo ze-SMC ziquka iinkcukacha ezininzi njengoko zincanyathiselwe, eziveliswa ngobuchwephesha bokubumba ubuchwephesha bobushushu.Imathiriyeli ekrwada yi-SMC eveliswe yi-D&F.
I-D&F ineqela lobuchwephesha lobuchwephesha kunye neworkshop ekhethekileyo yokwenziwa kwe-Precision machining ukuphuhlisa ukubumba kwezi profayili. Emva koko iworkshop yomatshini ye-CNC inokwenza iinxalenye zomatshini kwezi profayili.
