Ubuyobozi buhebuje kuri Brad Point Imyitozo: Bisobanutse neza kubakozi bakora ibiti
Icyerekezo cyihariye: Anatomy ya Brad Point Bit
Bitandukanye nibisanzwe bigoretse bizerera kuri contact, brad point drill bits iranga impinduramatwara yibice bitatu byubaka:
- Hagati ya Spike: Urushinge rumeze nk'urushinge rutobora ingano y'ibiti kuri zeru-wander iratangira
- Spur Blade: Urwembe rukarishye rwo hanze rukata fibre yibiti mbere yo gucukura, bikuraho amarira
- Umunwa wibanze: Gukata impande zose zitambitse zikuraho ibikoresho neza
Iyi trifecta itanga umwobo wukuri kubagwa-ingenzi kubice bya dowel, gushiraho hinge, hamwe no gufatanya kugaragara.
Imbonerahamwe: Brad Point na Biti bisanzwe
| Ubwoko bwa Bit | Ingaruka zo kurira | Icyitonderwa | Koresha Urubanza |
|---|---|---|---|
| Ingingo ya Brad | Hasi cyane | Kwihanganira 0.1mm | Ibikoresho byiza, dowel |
| Twist Bit | Hejuru | Kwihanganira 1-2mm | Kubaka nabi |
| Spade Bit | Guciriritse | 3mm + kwihanganira | Kwihuta cyane |
| Forstner | Hasi (gusohoka kuruhande) | Kwihanganira 0.5mm | Umwobo wo hasi |
| Inkomoko: Amakuru yo gupima inganda 210 |
Ubwubatsi Bwiza: Ibisobanuro bya tekiniki
Premium brad point bits ihuza metallurgie yihariye hamwe no gusya neza:
- Ubumenyi bwibikoresho: Ibyuma byihuta (HSS) byiganjemo igice cya premium, hamwe na titanium-nitride yometseho ubuzima burambye. HSS igumana ubukana 5x kurenza ibyuma bya karubone munsi yubushyuhe.
- Groove Geometry: Imiyoboro ya Twin spiral ikuramo chip 40% byihuse kuruta ibishushanyo mbonera, birinda gufunga umwobo muremure.
- Udushya twa Shank: 6.35mm (1/4 ″) hex shanks ituma kunyerera bitanyerera kandi bigahinduka byihuse kubashoferi.

| Diameter (mm) | Uburebure bw'akazi (mm) | Ubwoko bwiza bwibiti | Max RPM |
|---|---|---|---|
| 2.0 | 24 | Balsa, Pine | 3000 |
| 4.0 | 43 | Igiti, Ikarita | 2500 |

Impamvu abakora ibiti barahira amanota ya Brad: Inyungu 5 zidashoboka
- Zeru-Kwiyunga Nukuri
Igicucu cyo hagati gikora nka CNC ikorera, igera kuri 0.5mm ndetse no hejuru yuhetamye 5. Bitandukanye na Forstner bits isaba umwobo windege, amanota yerekana. - Ikirahure-Cyoroshye Urukuta
Spur blade yerekana umuzenguruko mbere yo gucukura, bikavamo umwobo witeguye kurangiza udakeneye umusenyi-uhindura umukino kugirango uhuze. - Ikirenga Cyimbitse
Uburebure bwa 75mm + bwo gukora kuri 8mm bits (hamwe na 300mm yagura iraboneka) ituma gucukura binyuze mumbaho 4 × 4 mumurongo umwe. Gukuramo ibishishwa birinda guhambira. - Guhinduranya Ibikoresho
Hanze y'ibiti n'ibiti byoroshye, amanota meza ya HSS yerekana acrylics, PVC, ndetse n'amabati yoroheje ya aluminiyumu atabanje gukata. - Ubukungu bwubuzima
Nubwo 30-50% bifite agaciro kuruta kugoreka bits, kugarurwa kwabo kubagira ibikoresho byubuzima. Umwuga ukarishye usaba $ 2-5 / bit yo kugarura.
Kumenya Bit: Pro Technique na Pitfalls
Amabanga yihuta
- Ibiti bikomeye (oak, maple): 1.500-2000 RPM kuri bits munsi ya 10mm
- Ibiti byoroshye (pinusi, imyerezi): 2,500-3000 RPM yo kwinjira neza;
- Diameter> 25mm: Tera munsi ya 1,300 RPM kugirango wirinde gukata.
Gusohoka Kurinda
- Shira ikibaho cyibitambo munsi yakazi
- Mugabanye umuvuduko wibiryo mugihe inama igaragaye
- Koresha Forstner bits kumwobo urenga 80% ubunini bwibintu.
Imihango yo Kubungabunga
- Sukura resin kwiyubaka hamwe na acetone ako kanya nyuma yo kuyikoresha.
- Ubike mumaboko ya PVC kugirango wirinde inkingi.
- Intoki zikarisha intoki hamwe na dosiye y'urushinge rwa diyama - ntuzigere usya intebe.
