Sarudzo yekusarudza

ChiiTwist Driing?

Twist Drill izwi rakasiyana-siyana remhando dzakasiyana siyana dzekutengeswa, senge simbi dzinodhara, madhiraivha epurasitiki, madhiragi ekufambisa, madhiri ezvematongerwo enyika. Zvese zvinodhaka twist zvine hunhu hwakajairika: iyo mahwendefa echihombe ayo anopa kudziya zita ravo. Madhiri akasarudzika ekutenderera anoshandiswa zvichienderana nekuomerwa kwezvinhu zvichisimudzwa.

NaHelix Angle

Type n

●Inokodzera zvinhu zvakajairika senge zvakakandwa simbi.
●Iyo mhando n yekucheka doro inosiyana nekuda kweiyo twist kona yeiyo approx. 30 °.
Iyo poindi angle yerudzi urwu ndeye 118 °.

Nyora h

●Yakanakira kuomarara uye brittle zvinhu zvakadai sendarira.
●Type H Helix angle iri kutenderera 15 °, iyo inoguma neiyo yakakura muchengeti nekona neisina kupinza asi yakagadzikana yekucheka.
●Type H Dries zvakare ine poindi angle ye118 °.

Type W

●Inoshandiswa kune zvinyoro nyoro senge aluminium.
●Iyo helix angle ye approx. 40 ° Mhedzisiro mune diki yedhi imwe kona yeiyo inopinza asi yakaenzana isina kugadzikana kucheka muganho.
●Iyo poindi angle ndeye 130 °.

Nezvinhu

Yakakwira Speed Steel (HSS)

Izvo zvinyorwa zvinogona kukamurwa kuita matatu marudzi: yakakwira-yekumhanyisa simbi, cobalt-ine yakakwira-yekumhanyisa simbi uye yakasimba carbide.

Kubva muna 1910, yakakwira-yekumhanyisa simbi yakashandiswa sechinhu chekucheka kweanopfuura makore zana. Parizvino parizvino inoshandiswa zvakanyanya uye yakachipa zvinhu zvekucheka zvishandiso. Yakakwira-yekumhanyisa simbi inodhira inogona kushandiswa mune ese ruoko ruoko kudhiraivha Chimwe chikonzero nei simbi yakakwirira-yekumhanyisa inogara kwenguva yakareba inogona kunge iri nekuti yakakwira-yekumhanyisa simbi yekucheka maturusi anogona kuve mumisangano. Nekuda kwemutengo wayo wakaderera, haingobatwi chete kushandiswa kudhiraivha, asiwo kushandiswa kwakawanda mukutendeuka.

Cobalt-ine yakakwira-yekumhanyisa simbi (HSSE)

Cobalt-ine yakakwira-yekumhanyisa simbi ine kuomarara kuri nani uye kuomarara kwetsvuku pane yakakwira-kumhanya simbi. Kuwedzera kwekusagadzikana kunovandudza kupfeka kwaro, asi panguva imwe chete zvibayiro zvekuomeserwa kwayo. Izvo zvakafanana neyekumhanya-simbi: Ivo vanogona kushandiswa kuwedzera huwandu hwenguva kuburikidza nekukuya.

Barbide (carbide)

Cementcarbide is simbi yakavakirwa simbi zvinyorwa. Pakati pavo, tungsten clabide inoshandiswa sematrix, uye zvimwe zvimwe zvinhu zvinoshandiswa seBinders kuti titadze nekupisa zvisikwa uye nhevedzano yematanho akaomarara. Kuenzaniswa neyakakwirira-yekumhanyisa simbi maererano nekuomerwa, kuomesa kutsvuka uye kupfeka kuramba, zvakavandudzwa zvikuru. Asi mutengo weCyment Carbide kucheka maturusi zvakare zvakare zvakanyanya kudhura kupfuura yakakwira-yekumhanyisa simbi. Carmed carbide ine zvimwe zvakanakira kupfuura zvakapfuura zvishandiso zvekushandisa maererano nehupenyu hwehupenyu uye yekugadzirisa kumhanya. Mukukudzwa kwakadzokororwa kwezvishandiso, nyanzvi yekugaya zvishandiso zvinodiwa.

Nekubatanidza

Haina

Coatings inogona kukamurwa mumhando dzinotevera shanu zvinoenderana neyekushandisa.

Zvishandiso zvisina kubhururuka ndizvo zvinodhura uye zvinowanzoshandiswa kugadzirisa zvimwe zvakapfava senge aluminium Alloy uye yakaderera carbon simbi.

Dema oxide coating

Coatings oxings inogona kupa zvirinani kupfuura zvishandiso zvisina kufanira, zviri nani zviri nani mune oxidation uye kupisa kupesana, uye kunogona kuwedzera hupenyu hwebasa neanopfuura 50%.

Titanium Nitride Coating

Titanium Nitride ndiyo inonyanya kuzivikanwa zvinyorwa, uye haina kukodzera kune zvigadzirwa zvine hutsinye hwakanyanya uye zvakakwirira zvekudzokorora.

Titanium carbonitride coating

Titanium Carbonitride inovandudzwa kubva kuTitanium nitride, ine yakakwira tembiricha yekudziya uye kupfeka kurwisa, kazhinji yepepuru kana yebhuruu kana yebhuruu. Inoshandiswa mumusangano weHaas kumuchina wokushanda zvakagadzirwa nesimbi.

Titanium aluminium nitride coating

Titanium aluminium nitride inonyanya kupokana nekudziya kwakanyanya kupfuura zvese zvataurwa pamusoro, saka zvinogona kushandiswa munzvimbo dzakakwirira dzekucheka. Semuenzaniso, kugadzirisa ma supacloys. Zvakakodzerawo kugadziriswa kwesimbi uye simbi isina simba, asi iyo ine aluminium zvinhu, maitiro emakemikari achaitika kana achigadzirisa aluminium, saka dzivirira kugadzirisa zvinhu zvine aluminium.

Chii chinonzi HSS madhiri?
HSS madhiraivha ari madhiraivha ebvezi ayo anoonekwa nemhedzisiro yavo yemamiriro ekunze. Kunyanya muzvikamu zvidiki uye zvepakati

Misiyano muHSS HSS
Yakakwira-yekumhanyisa simbi yakakamurwa kuita akasiyana mhando mazinga zvichienderana nekuomarara uye kuoma. Alloy zvikamu senge tungsten, Molybdenum naCobalt vane mutoro kune izvi zvivakwa. Kuwedzera zvinhu zvezvikamu zvinowedzera zvinowedzera kudzikisira, kupfeka kuramba uye kuita kwechishandiso, pamwe nemutengo wekutenga. Ndokusaka zvichikosha kufunga kuti vangani maburi anofanira kugadzirwa mune izvo zvinhu pakusarudza zvinhu zvekucheka. Kune vashoma vashoma maburi, iyo yakanyanya mutengo-yekucheka zvinyorwa zvehunhu HSS zvinokurudzirwa. Yakakwirira-mhando yekucheka zvinhu senge HSCO, M42 kana HSS-E-PM inofanirwa kusarudzwa kuti ive mutungamiri kugadzirwa.
