Kodi mungasankhe bwanji chobowolera?

Lero, ndigawana momwe ndingasankhire chobowolera pogwiritsa ntchito zinthu zitatu zofunika kwambirichobowolera, zomwe ndi: zinthu, zokutira ndi mawonekedwe a geometric.

Momwe mungasankhire zinthu zogwiritsira ntchito kubowola

Zipangizo zitha kugawidwa m'magulu atatu: chitsulo chothamanga kwambiri, chitsulo chothamanga kwambiri chokhala ndi cobalt ndi carbide yolimba.

Chitsulo Chothamanga Kwambiri (HSS):

Chitsulo chothamanga kwambiri ndi chida chodulira chomwe chimagwiritsidwa ntchito kwambiri komanso chotsika mtengo kwambiri pakadali pano. Chitsulo chodulira chachitsulo chothamanga kwambiri chingagwiritsidwe ntchito osati pa ma drill amagetsi okha, komanso m'malo okhala ndi kukhazikika bwino monga makina obowola. Chifukwa china chomwe chimapangitsa kuti chitsulo chothamanga kwambiri chikhale cholimba ndichakuti chida chopangidwa ndi chitsulo chothamanga kwambiri chikhoza kuphwanyidwa mobwerezabwereza. Chifukwa cha mtengo wake wotsika, sichimagwiritsidwa ntchito pongopera ma drill, komanso chimagwiritsidwa ntchito kwambiri potembenuza zida.

Cobalt High Speed ​​​​Steel (HSSCO):

Chitsulo chothamanga kwambiri chokhala ndi Cobalt chili ndi kuuma bwino komanso kufiira kuposa chitsulo chothamanga kwambiri, ndipo kuuma kwake kumawonjezeranso kukana kwake kuwonongeka, koma nthawi yomweyo kumataya gawo la kulimba kwake. Mofanana ndi chitsulo chothamanga kwambiri: zingagwiritsidwe ntchito kukweza kuchuluka kwa nthawi popera.

 

Carbide (CARBIDE):

Carbide yopangidwa ndi simenti ndi chinthu chopangidwa ndi chitsulo. Pakati pawo, tungsten carbide imagwiritsidwa ntchito ngati matrix, ndipo zipangizo zina zimagwiritsidwa ntchito ngati chomangira chomwe chimasungunuka ndi njira zingapo zovuta monga kukanikiza kwa isostatic kotentha. Poyerekeza ndi chitsulo chothamanga kwambiri pankhani ya kuuma, kuuma kofiira, kukana kutopa, ndi zina zotero, pali kusintha kwakukulu, koma mtengo wa zida za simenti za carbide ndi wokwera mtengo kwambiri kuposa chitsulo chothamanga kwambiri. Carbide ili ndi ubwino wambiri kuposa zida zakale pankhani ya moyo wa chida ndi liwiro lokonza. Pakupukutira mobwerezabwereza zida, zida zaukadaulo zopukutira zimafunika.

Momwe mungasankhire chophimba cha kubowola

Zophimba zitha kugawidwa m'magulu asanu otsatirawa malinga ndi momwe zimagwiritsidwira ntchito.

Wosaphimbidwa:

Mipeni yopanda utoto ndiyo yotsika mtengo kwambiri ndipo nthawi zambiri imagwiritsidwa ntchito popanga zinthu zofewa monga aluminiyamu ndi chitsulo chofewa.

Chophimba chakuda cha okusayidi:

Zophimba zopangidwa ndi okosijeni zimatha kupereka mafuta abwino kuposa zida zosaphimbidwa, komanso zimakhala bwino pankhani ya okosijeni ndi kukana kutentha, ndipo zimatha kuwonjezera moyo wautumiki ndi zoposa 50%.

Chophimba cha titaniyamu nitride:

Titanium nitride ndiye chinthu chofala kwambiri chophikira ndipo sichiyenera kugwiritsidwa ntchito pazinthu zolimba kwambiri komanso kutentha kwambiri.

Chophimba cha titaniyamu ya carbonitride:

Titanium carbonitride imapangidwa kuchokera ku titanium nitride ndipo imakhala ndi kutentha kwambiri komanso kusawonongeka, nthawi zambiri imakhala yofiirira kapena yabuluu. Imagwiritsidwa ntchito popanga zida zopangira chitsulo ku Haas workshop.

Chophimba cha Aluminium Nitride Titanium:

Aluminium titanium nitride imapirira kutentha kwambiri kuposa zokutira zonse zomwe zatchulidwa pamwambapa, kotero ingagwiritsidwe ntchito m'malo odulira kwambiri. Mwachitsanzo, kukonza ma superalloys. Ndi yoyeneranso kukonza chitsulo ndi chitsulo chosapanga dzimbiri, koma chifukwa cha zinthu zomwe zili ndi aluminiyamu, zotsatira za mankhwala zimachitika pokonza aluminiyamu, choncho pewani kukonza zinthu zomwe zili ndi aluminiyamu.

Jiometri ya kubowola

Mawonekedwe a geometric akhoza kugawidwa m'magawo atatu otsatirawa:

Utali

Chiŵerengero cha kutalika ndi m'mimba mwake chimatchedwa double diameter, ndipo double diameter ikakhala yaying'ono, kulimba kwake kumakhala bwino. Kusankha drill yokhala ndi m'mphepete mwake kuti ichotse chip ndi kutalika kwake kochepa kungathandize kuti chidacho chikhale cholimba panthawi yokonza, motero kuwonjezera nthawi yogwira ntchito ya chidacho. Kutalika kosakwanira kwa tsamba kungawononge drill.

Ngodya ya nsonga ya kubowola

Ngodya yobowola ya 118° mwina ndiyo yodziwika kwambiri pamakina ndipo nthawi zambiri imagwiritsidwa ntchito pazitsulo zofewa monga chitsulo chofewa ndi aluminiyamu. Kapangidwe ka ngodya iyi nthawi zambiri sikodziyimira payokha, zomwe zikutanthauza kuti n'kosapeweka kuyika kaye dzenje lozungulira. Ngodya yobowola ya 135° nthawi zambiri imakhala ndi ntchito yodziyimira payokha. Popeza palibe chifukwa choyika dzenje lozungulira, izi zimapangitsa kuti kubowola dzenje lozungulira kukhale kosafunikira padera, zomwe zimapangitsa kuti musunge nthawi yambiri.

Ngodya ya Helix

Ngodya ya helix ya 30° ndi chisankho chabwino pazinthu zambiri. Koma m'malo omwe amafunika kuchotsedwa bwino kwa chip komanso m'mphepete mwamphamvu, chobowola chokhala ndi ngodya yaying'ono ya helix chingasankhidwe. Pazinthu zovuta kugwiritsa ntchito monga chitsulo chosapanga dzimbiri, kapangidwe kamene kali ndi ngodya yayikulu ya helix kamasankhidwa kuti katumize mphamvu.
