Mashandisiro Aungaita Drill?

Nhasi, ini ndichagovera maitiro ekusarudza kudhiraira zvishoma kuburikidza nemamiriro matatu ekutanga eDrill Bit, ndedzipi: zvinhu, kuunganidza uye geometric hunhu.

Maitiro ekusarudza zvinyorwa zvekurohwa

Zvigadzirwa zvinogona kukonzerwa nemhando nhatu: yakakwira-yekumhanyisa simbi, cobalt-ine yakakwira-yekumhanyisa simbi uye yakasimba carbide.

Yakakwira Speed ​​Steel (HSS):

Yakakwira-yekumhanyisa simbi parizvino inonyanya kushandiswa uye yakachipa yekucheka zvinhu zvekushandisa. Kudhirowa kwesimbi yakakwirira-yekumhanyisa kunogona kushandiswa kwete chete pamagetsi magetsi ekurira, asiwo munzvimbo dzakasimba kwazvo senge michina yekudhara. Chimwe chikonzero chengozi hurefu hwesimbi yakakwirira-yekumhanyisa inogona kunge iri iyo chishandiso chakagadzirwa neyakaomerwa simbi inogona kuve yakadzokororwa. Nekuda kwemutengo wayo wakaderera, haina kungoshandiswa chete pakukuya kuita mabhegi ekurova, asi zvakare inoshandiswa zvakanyanya mukutendeuka.

Cobalt Yakakwira Speed ​​Steel (HSSCO):

Cobalt-ine simbi yekumhanya yakakwira ine kuomesa uye kuomarara kwetsvuku pane simba rakakwira, uye kuwedzera kwakawanda kunovandudza kupfeka kwaro, asi panguva imwe chete zvibayiro zvekuomesesa. Izvo zvakafanana neyekumhanya-kumhanya simbi: Ivo vanogona kushandiswa kugadzirisa huwandu hwenguva nekukuya.

 

Barbide (carbide):

Carmed carbide is simbi yakavakirwa simbi zvinyorwa. Pakati pavo, tungsten carbide inoshandiswa sematrix, uye zvimwe zvigadzirwa zvezvimwe zvinhu zvinoshandiswa sekusungwa kuti chibatwe nenhevedzo yeakateedzana yakadai seinopisa nzvimbo yekumanikidza. Kuenzaniswa neyekumhanya-simbi Carbide ine zvimwe zvakanakira kupfuura zvakapfuura zvishandiso zvekushandisa maererano nezvishandiso zvehupenyu uye kugadzirira kumhanya. Mukukudzwa kwakadzokororwa kwezvishandiso, nyanzvi yekugaya zvishandiso zvinodiwa.

Maitiro ekusarudza kudhiraivha kuunganidza

Mabhonzo anogona kuve akaiswa mumhando dzinotevera shanu zvinoenderana neyekushandisa.

Haina:

Mapundu asina kubhururuka ndiye anodhura uye anowanzoshandiswa kumuchina zvigadzirwa zvakaita sealuminium alloys uye nyoro nyoro.

Dema cofi coating:

Oxidized Coatings inogona kupa zviri nani lubricity kupfuura isina kusarudzika zvishandiso, uye zvakare zviri nani maererano ne oxidation uye kupisa kupokana, uye kunogona kuwedzera hupenyu hwebasa neanopfuura 50%.

Titanium Nitride Coating:

Titanium Nitride ndiyo yakajairika yekubatanidza zvinhu uye haina kukodzera kugadzirisa zvinhu zvine hupfu hwakanyanya uye hwakanyanya hwekuita tembiricha.

Titanium Carbonitride Coating:

Titanium Carbonitride inovandudzwa kubva kuTitanium nitride uye ine yakakwira tembiricha uye kupfeka kuramba, kazhinji yepepuru kana yebhuruu kana yebhuruu. Yaimboita muchina ikakamisa simbi inoshanda mumusangano weHaas.

Aluminium Nitride Titanium Coating:

Aluminium titanium nitride inodzivirira kupisa kwakanyanya kupfuura zvese zvataurwa pamusoro, saka zvinogona kushandiswa munzvimbo dzakakwirira dzekucheka. Semuenzaniso, kugadzirisa ma supacloys. Izvo zvakare zvakakodzera kugadziriswa kwesimbi uye simbi isina simba, asi nekuda kwezvinhu zvine aluminium, maitiro emakemikari zvichaitika kana kugadziriswa aluminium, saka dzivirira kugadzirisa aluminium-ine zvinhu.

Drill Bit Geometry

Geometric maitiro anogona kukamurwa mune inotevera zvikamu zvitatu:

Kureba

Iyo chiyero chekureba kune diameter inodaidzwa kuti DIAMETER DIAMETER, uye zvidiki zvakapetwa kaviri, zviri nani kuomarara. Kusarudza kudhiraivha nehurefu hwepamhepo kungobvisa chipavira uye ipfupi yakanyanyisa kuderera kunogona kuvandudza kuomesa panguva yekuchina, nekudaro kuenderera mberi nehupenyu hwebasa. Isina kukwana blade urefu ingangove ichikuvadza iyo yekukwevera.

Drill Tip Angle

A Drill Tip Angle of 118 ° ingangoita zvakanyanya mumachinji uye inowanzoshandiswa simbi nyoro dzakadai sesimbi nyoro uye aluminium. Kugadzirwa kweiyi kona kazhinji hakuwanzo kuzvishandisa, zvinoreva kuti hazvigoneke kuchina muchina gomba rekutanga. Iyo 135 ° Drill tip kona kazhinji inowanzova neyako-yekuzvifunga basa. Sezvo pasina chikonzero chekushayamira gomba rakatanga, izvi zvichaita kuti zvive zvisina basa kugeza gomba repasi rose zvakasiyana, nokudaro vachiponesa nguva yakawanda.

Helix angle

A helix angle ye30 ° isarudzo yakanaka yezvinhu zvakawanda. Asi zvenzvimbo dzinotsvaga zvirinani chip zvekuputira uye chivharo chakasimba chekucheka, kudhiraivha uine diki helix angle inogona kusarudzwa. Zvekunetseka-kune-machina zvigadzirwa senge simbi isina tsvina, dhizaini ine helix yakakura inogona kusarudzwa kuendesa torque.
