• Super coarse grain hard alloy virgin raw material , 100 % ialloy ngokucofa kunye ne sintering , ukwenzela ukuba ubulukhuni kunye nokuqina kwentwana yedrill yande ngama 30 % ngaxeshanye .
• Uyilo olulodwa, Ukugrumba kunye nesantya sokwemba nyusa ama-20%, ubomi bokwandisa ngama-30%.
• Uzinzo lweDimensional kwimo engqongileyo enobushushu obuphezulu kunye neemeko zoxinzelelo
• Ukugqiba kakuhle okwenza kube lula ukucoca
• Ukuxhathisa okukhulu kokunxiba, ukuxhathisa i-abrasion
• Iindleko ezisebenzayo ngenxa yobomi obude kunye neemfuno zolondolozo ezingahoywanga.
(1) phantsi kweemeko ezithile, ezinje ngobubanzi bombhobho, i-engile yokutofa kunye nomgama wokutshiza, okukhona uphezulu uxinzelelo lwejethi, kokukhona isiphumo sokuqhekeka kwamatye siya kuba ngcono;
(2) phantsi komqathango wokuba umbhobho wedayamitha, inaliti ye-engile kunye nesantya sokuhamba somlomo sihlala sihleli, umgama wokutshiza ungowona unyuka ngokunyuka koxinzelelo, ufikelela kumaxesha angama-32.5 edayamitha yombhobho kwi-200MPa;
(3) undoqo wesantya sombhobho oshukumayo kukubonakalisa ixesha lentshukumo yelitye lokhukuliseko lwejethi.Xa ingaphantsi kwe-2.9mm/s, inempembelelo encinci kwisiphumo sokhukuliseko lwamatye.
(4) xa uxinzelelo lungaphantsi kwe-150MPa, uxinzelelo lwejethi luyanda kwaye umthamo wokuqhekeka kwamatye kwiyunithi nganye amandla anyuka ngokukhawuleza;nangona kunjalo, xa uxinzelelo lukhula ngakumbi, umthamo wokuqhekeka kwamatye kwiyunithi nganye yehla kancinci, kwaye ukusebenza kakuhle kokuqhekeka kwamatye kuphezulu kwi-150MPa.
(5) i-nozzle ephezulu yoxinzelelo oluphezulu ihamba kwimowudi yangaphambili, kunye neyona mpembelelo intle yokuqhekeza ilitye kunye ne-Angle ye-injection engcono ye-12.50.
