Nzira yekusarudza drill?

Nhasi, ini ndichagovera nzira yekusarudza drill bit kuburikidza nematatu ekutanga mamiriro eiyodrill bit, izvo zviri: zvinhu, kupfeka uye geometric maitiro.

Nzira yekusarudza zvinhu zve drill

Zvishandiso zvinogona kukamurwa kuita mhando nhatu: simbi inomhanya-mhanya, cobalt-ine high-speed simbi uye yakasimba carbide.

High Speed ​​​​Simbi (HSS):

HSS yekupedzisira chigayo

High-speed simbi parizvino ndiyo inonyanya kushandiswa uye yakachipa yekucheka maturusi emidziyo.Iyo drill bit of high-speed simbi inogona kushandiswa kwete chete pamaoko emagetsi drills, asiwo munzvimbo dzine kugadzikana kuri nani semichina yekuchera.Chimwe chikonzero chekugara kwenguva refu kwesimbi yepamusoro-soro inogona kunge iri iyo yakagadzirwa nesimbi yepamusoro inogona kudzokororwa pasi.Nekuda kwemutengo wakaderera, haingoshandiswe chete kukuya kuita zviboorero, asi zvakare inoshandiswa zvakanyanya mukushandura maturusi.

Cobalt High Speed ​​​​Simbi (HSSCO):

Cobalt-ine high-speed simbi ine nani kuoma uye mutsvuku kuoma kupfuura high-speed simbi, uye kuwedzera kuoma kunowedzerawo kunonatsiridza kwayo kupfeka kuramba, asi panguva imwe chete zvibayiro chikamu kuoma kwayo.Zvakafanana nesimbi yepamusoro-soro: inogona kushandiswa kuvandudza nhamba yenguva nekukuya.

 

Carbide (CARBIDE):

Cemented carbide isimbi-based composite material.Pakati pazvo, tungsten carbide inoshandiswa sematrix, uye zvimwe zvinhu zvezvimwe zvinhu zvinoshandiswa sebhainda kuti rinyorwe nenhevedzano yemaitiro akaomarara akadai seanopisa isostatic kudzvanya.Kuenzaniswa nesimbi inomhanya-mhanya maererano nekuoma, kuomarara kwakatsvuka, kupfeka kusagadzikana, nezvimwewo, kune kuvandudzwa kukuru, asi mutengo wesimende zvishandiso zvecarbide zvakare unodhura zvakanyanya kupfuura simbi inomhanya.Carbide ine mabhenefiti akawanda kupfuura ekare maturusi emidziyo maererano nehupenyu hwematurusi uye kumhanya kwekugadzirisa.Mukudzokororwa kwezvishandiso, maturusi ekukuya anodiwa anodiwa.

Nzira yekusarudza chibooreso chekuputira

Coatings inogona kuverengerwa mumhando shanu dzinotevera zvichienderana nehukuru hwekushandisa.

Isina kuvharwa:

Mapanga asina kuvharwa ndiwo akachipa uye anowanzo shandiswa kugadzira zvinhu zvakapfava zvakaita sealuminium alloys nesimbi yakapfava.

Black oxide coating:

Oxidized coatings inogona kupa lubricity iri nani pane maturusi asina kuvharwa, uye zvakare iri nani maererano neoxidation uye kupisa kupisa, uye inogona kuwedzera hupenyu hwesevhisi neinopfuura 50%.

Titanium nitride coating:

Titanium nitride ndiyo yakajairika yekubatisa zvinhu uye haina kukodzera kugadzirisa zvinhu zvine hurema hwakanyanya uye yakanyanya kupisa tembiricha.

Titanium carbonitride coating:

Titanium carbonitride inogadzirwa kubva patitanium nitride uye ine tembiricha yakakwira uye inodzivirira kupfeka, kazhinji yepepuru kana yebhuruu.Inoshandiswa kugadzira masimbi ekukanda masimbi mumusangano weHaas.

Aluminium Nitride Titanium Coating:

Aluminium titanium nitride inonyanya kupikisa kupisa kwepamusoro kupfuura zvese zviri pamusoro apa, saka inogona kushandiswa munzvimbo dzepamusoro dzekucheka.Somuenzaniso, kugadzirisa superalloys.Inokodzerawo kugadzirwa kwesimbi uye simbi isina tsvina, asi nekuda kwezvinhu zvine aluminium, kemikari inogadziriswa ichaitika kana uchigadzira aluminium, saka dzivisa kugadzirisa aluminium-ine zvinhu.

Drill bit geometry

Zvimiro zveGeometric zvinogona kukamurwa kuita zvikamu zvitatu zvinotevera:

Urefu

END MILL2

Chiyero chehurefu kusvika kudhayamita chinonzi kaviri dhayamita, uye diki dhayamita kaviri, zviri nani kuomarara.Kusarudza chibooreso chine hurefu hwemupendero kungobvisa chip uye kureba kupfupi kwepamusoro kunogona kuvandudza kusimba panguva yekugadzira, nekudaro kuwedzera hupenyu hwesevhisi yechishandiso.Kusakwana kweblade kureba kungangokuvadza chibooreso.

Drill tip angle

kupera mill3

A drill tip angle ye 118° ingangove yakanyanya kuwanda mukugadzira uye inowanzo shandiswa simbi dzakapfava sesimbi yakapfava nealuminium.Dhizaini yekona iyi kazhinji haisi yekuzvimiririra, izvo zvinoreva kuti hazvidzivirirwe kutanga muchina buri repakati.Iyo 135 ° drill tip angle inowanzoita yekuzvimirira.Sezvo pasina chikonzero chekugadzira gomba repakati, izvi zvichaita kuti zvive zvisina kufanira kuchera gomba repakati zvakasiyana, nekudaro kuchengetedza nguva yakawanda.

Helix angle

kupera 5

Helix angle ye30 ° isarudzo yakanaka kune zvakawanda zvekushandisa.Asi kune nharaunda dzinoda zvirinani chip evacuation uye yakasimba yekucheka edge, drill ine diki helix angle inogona kusarudzwa.Kune zvakaoma-ku-muchina zvinhu zvakadai sesimbi isina tsvina, dhizaini ine hombe helix angle inogona kusarudzwa kutumira torque.
