Woodworking inyanzvi inoda kunyatsojeka uye mhizha, uye pamwoyo wemhizha chinhu chinokosha - chibooreso chehuni. Kunyangwe iwe uri muvezi ane ruzivo kana DIY anofarira, kuziva nzira yekusarudza nekushandisa iyo chaiyo drill bit kwakakosha kune inobudirira basa rekugadzira huni.

Mugwaro rino rakazara, tichaongorora maomesero ezvibooreso zvehuni, tichiongorora marudzi akasiyana-siyana, saizi, zvishandiswa, uye machira anobatsira mukushanda kwawo.

Ngatitangei kuongorora maturusi ekutanga anoumba matanda makuru.

Kusuma yeWood Drill Bit

Material

Zvishandiso zvakawanda zvakasiyana-siyana zvinoshandiswa kana pazviboorero, zvichienderana nekushandiswa kunodiwa.

Tungsten Carbide: Tungsten carbide uye mamwe macarbides akaomarara uye anogona kudhiraivha zvinenge zvese, asi akabata mupendero wakareba kupfuura mamwe mabhiti. Izvo zvinhu zvinodhura uye zvakanyanya brittle kupfuura simbi; nokudaro anonyanya kushandiswa pakubooresa-bhiti matipi, zvidimbu zvidiki zvezvinhu zvakaomarara zvakagadzikwa kana kuti brazed pamuromo wechidimbu chakagadzirwa nesimbi isina kuomarara.

Nekudaro, zvave kuita zvakajairika muzvitoro zvebasa kushandisa yakasimba carbide bits. Muhukuru hudiki kwazvo zvakaoma kuenderana necarbide matipi; mune mamwe maindasitiri, kunyanya akadhindwa redunhu bhodhi kugadzira, zvinoda maburi akawanda ane diameter isingasviki 1 mm, yakasimba carbide bits inoshandiswa.

PCD:Polycrystalline diamond (PCD) iri pakati pezvakaomesesa pane ese maturusi maturusi uye nekudaro inoshingirira kupfeka. Iyo ine chidimbu chezvidimbu zvedhaimondi, kazhinji zvingangoita 0.5 mm (0.020 mukati) gobvu, yakasungirirwa seredhi resimbi kune tungsten-carbide rutsigiro.

Mabhiti anogadzirwa achishandisa chinhu ichi nekukwenya zvidimbu zvidiki kumucheto wechishandiso kugadzira mipendero yekucheka kana nekupinza PCD mutsinga mune tungsten-carbide "nib". Iyo nib inogona gare gare yakashongedzwa kune carbide shaft; inogona kubva yadzika kune yakaoma geometries izvo zvingakonzeresa kutadza kwebraze mu "zvikamu" zvidiki.

PCD bits anowanzo shandiswa mumotokari, aerospace, uye mamwe maindasitiri kudhiza abrasive aluminum alloys, carbon-fiber reinforced mapurasitiki, uye zvimwe zvinokurisa, uye mumashandisirwo apo muchina nguva yekutsiva kana kurodza mabhiti akasakara inodhura zvakanyanya. PCD haishandiswe pamasimbi ane ferrous nekuda kwekunyanya kupfeka kunokonzerwa nekuita pakati pekabhoni muPCD uye simbi musimbi.

Simbi

Zvimedu zvesimbi zvakapfavahazvidhure, asi hazvibate mupendero zvakanaka uye zvinoda kugara uchirodza. Zvinoshandiswa chete pakuchera huni; kunyange kushanda nematanda akaoma pane softwoods kunogona kuonekwa kupfupisa hupenyu hwavo.

Bits yakagadzirwa kubvahigh-carbon steelakasimba kupfuurapasi-carbon steel bitsnekuda kwezvivakwa zvinopihwa nekuomesa nekudzikamisa zvinhu. Kana vakapisa zvakanyanya (semuenzaniso, nekudziya kwekupokana vachiboora) vanotadza kushatirwa, zvichikonzera kucheka kwakapfava. Aya mabheti anogona kushandiswa pamatanda kana simbi.

Simbi yepamusoro-soro (HSS) imhando yesimbi yekushandisa; HSS bits dzakaoma uye zvakanyanya kushingirira kupisa kupfuura high-carbon steel. Zvinogona kushandiswa kuchera simbi, matanda akaomarara, uye zvimwe zvinhu zvakawanda nekumhanya kukuru kwekucheka pane kabhoni-simbi mabits, uye zvakanyanya kutsiva kabhoni simbi.

Cobalt simbi alloysmisiyano pane yakakwirira-kumhanya simbi ine yakawanda cobalt. Vanobata kuoma kwavo patembiricha yakakwira zvakanyanya uye vanoshandiswa kuchera simbi isina tsvina nezvimwe zvinhu zvakaomarara. Iko kusakosha kukuru kwesimbi yecobalt ndeyekuti yakanyanya brittle kupfuura yakajairwa HSS.

Coating

Black oxide

Black oxide ijira risingadhure dema. A black oxide coating inopa kupisa kwekudzivirira uye lubricity, pamwe nekudzivirira kupisa. Iyo yekuputira inowedzera hupenyu hwepamusoro-kumhanya mabhiti esimbi

Titanium nitride

Titanium nitride (TiN) isimbi yakaoma kwazvo inogona kushandiswa kupfekedza simbi inomhanya-mhanya (kazhinji twist bit), ichiwedzera hupenyu hwekucheka katatu kana kupfuura. Kunyangwe mushure mekurodza, iyo inotungamira mupendero wejasi ichiri kupa yakagadziridzwa kucheka uye hupenyu hwese.

Hunhu

point angle

Kona yepoinzi, kana kona yakaumbwa kumucheto kwebhiti, inotariswa nechinhu icho bhiti richange richishanda mariri. Zvinhu zvakaomarara zvinoda kona yepoinzi hombe, uye zvinhu zvakapfava zvinoda kona yakapinza. Iyo chaiyo point angle yekuoma kwezvinhu zvinopesvedzera kudzungaira, chatter, hole shape, uye chiyero chekupfeka.

urefu

Hurefu hwekushanda kwechidimbu hunotarisa kuti gomba rakadzika sei rinogona kudhindwa, uye rinotarisawo kuoma kwebhiti uye kurongeka kwegomba rinoguma. Nepo mabhiti akareba achigona kuchera makomba akadzika, anochinja-chinja zvichireva kuti maburi avanoboora anogona kunge aine nzvimbo isina kurongeka kana kudzungaira kubva paakisi yainoda. Twist drill bits anowanikwa mukureba kwakajairwa, kunonzi Stub-length kana Screw-Machine-length (pfupi), iyo yakajairika Jobber-urefu (pakati), uye Taper-urefu kana Long-Series (yakareba).

Mabheti mazhinji ekushandisa kwevatengi ane shanks dzakatwasuka. Pakuchera basa rinorema muindasitiri, mabhiti ane tapered shanks dzimwe nguva anoshandiswa. Mamwe marudzi e shank anoshandiswa anosanganisira hex-shaped, uye akasiyana siyana evaridzi anokurumidza kuburitsa masisitimu.

Huyero hwedhayamita-kusvika-urefu hwechibhorani chinowanzova pakati pe1:1 ne1:10. Mareshiyo akakwirira zvikuru anogoneka (semuenzaniso, “ndege-kureba” mabhiti ekumonyorora, mabhiti ekubooresa oiri-akamanikidzwa, zvichingodaro), asi kana reshiyo yakakwira, dambudziko rehunyanzvi rekugadzira basa rakanaka rinokura.

Mhando dzeDrill Bits:

Saw blade Kana ikasashandiswa nekukasika, inofanira kunge yakati sandara kana kushandisa gomba kuti iturike, kana zvimwe zvinhu hazvigone kurongedzerwa pamasaha etsoka dzakatsetseka, uye mwando nekudzivirira ngura zvinofanirwa kutariswa.

Brad point bit (Dowel Drill Bit):

Iyo brad point drill bit (inozivikanwawo sekuti lip uye spur drill bit, uye dowel drill bit) musiyano we twist drill bit inogadziridzwa pakuchera muhuni.

Shandisa chibooreso chehuni chakati sandara kana kuti chibooreso chinotenderera, chakakodzera mabasa apo mabhaudhi kana nzungu zvinoda kuvanzwa.

Brad point drill bits anowanzo kuwanikwa mumadhayamita kubva 3–16 mm (0.12–0.63 mukati).

Kuburikidza nemakomba Drill Bit

A through gole igomba rinopinda nepaburi rebasa rese.

Shandisa spiral drill bit kuti upinde nekukurumidza, yakakodzera kune general basa rekuchera.

Hinge sinker bit

Iyo hinge sinker bit muenzaniso weyakajairwa dhizaini dhizaini kune chaiyo application.
Hinge yehunyanzvi yakagadzirwa iyo inoshandisa madziro e35 mm (1.4 in) dhayamita gomba, yakafinhwa muchikamu chebhodhi, kutsigira.

Forstner zvishoma

Forstner bits, yakatumidzwa zita remugadziri wayo, yakabereka maburi akanyatsodzika muhuni, mune chero maitiro ane chekuita nehuni tsanga. Vanogona kutema pamupendero wedanda rehuni, uye vanogona kucheka makomba akaturikidzana; maapplication akadaro anowanzo shandiswa mumichina yekudhirowa kana lathes kwete mumagetsi anobatwa nemaoko.

Mazano Madiki eKushandisa Wood Drill Bits

Kugadzirira

Ita shuwa kuti nzvimbo yebasa yakarongeka, kubvisa zvipingamupinyi zvinogona kutadzisa kuchera.
Sarudza midziyo yekuchengetedza yakakodzera, kusanganisira magirazi ekuchengetedza uye earmuffs.

Speed:Sarudza kumhanya kwakaringana zvichienderana nekuoma kwehuni uye bit type.
Kazhinji, kumhanya kunononoka kwakakodzera matanda akaomarara, nepo kukurumidza kumhanya kunogona kushandiswa

Mhedziso

Kubva pakunzwisisa manuances ekusarudza mhando chaiyo, saizi, uye zvinhu kusvika pakushandisa hunyanzvi hwepamberi sekugadzira mapofu uye kuburikidza nemakomba, zvese zvinokonzeresa kuhunyanzvi hwekugadzira huni.

Ichi chinyorwa chinotanga nenhanganyaya yemhando dzakakosha uye zvinhu zvezviboorero. Batsira kuvandudza ruzivo rwako rwehuni.

Koocut Zvishandiso zvinopa nyanzvi dzekubooresa mabhiti kwauri.

Kana uchichida, ndapota usazeza kutibata.
