Yɛrɛ faamuyali-Drilling Screw dɛsɛw: A sababuw, a kunbɛncogo, ani RPM ɲɛminɛcogo ɲuman
Yɛrɛ-kurunw dilannen don walasa ka jiriw sɔgɔ, ka u gosi, ka u siri baara kelen na. Nka, a sigicogo jugu bɛ se ka kɛ sababu ye ka foroko kuncɛ tiɲɛ joona ani ka a sirili tiɲɛ. Dɛsɛ suguya minnu kɔlɔsira foro kɔnɔ, u jujɔw, ani u kunbɛncogo, olu tilatilali bɛ duguma.
1. Flɛtiw Chipped
Ko min kɔlɔsira:
Tigɛminɛn minnu bɛ foroko yɔrɔ la, olu bɛ i n’a fɔ u karilen don walima u tigɛlen don sani u ka don kosɛbɛ.
A sababu fɔlɔw:
Aksidan fanga tɛmɛnen bolifɛn bolituma na
Aw bɛ kurukuruni waajibiya sani foroko yɔrɔ ka tigɛ daminɛ
Barika la, doni minnu bɛ bɔ bolifɛntigiw la minnu tɛ sabati
Ladilikanw minnu bɛ se ka bana kunbɛn:
Aw bɛ a to drill point ka tigɛ a yɛrɛ la sani aw ka dɔ fara degun kan
Baara kɛ ni fanga sabatilen ye, min bɛ kɔrɔsi sanni ka impact-style pushing kɛ
Aw bɛ aw jija ka sofa bitiki labɛn ka kɛɲɛ ni a sanfɛla ye
2. Dingɛ sɔgɔlen si ma dilan
Ko min kɔlɔsira:
Kuru bɛ girin k’a sɔrɔ a ma don nɛgɛdaga kɔnɔ.
A sababu fɔlɔw:
Base material hardness bɛ tɛmɛ drill point seko kan
Sotigi ye a bila ka kɔsegin a cogo la
Drill point blunt walima tiɲɛnen min bɛ sɔrɔ a minɛcogo walima a dilanni nafama fɛ
Ladilikanw minnu bɛ se ka bana kunbɛn:
Aw bɛ nɛgɛ janya ni a sɔgɔli fanga sɛgɛsɛgɛ sani a ka a sigi
Aw bɛ bolifɛntigi jiginni sira lajɛ sani aw ka bolifɛn boli
Aw bɛ foroko yɔrɔw lajɛ ni u tiɲɛna sani aw ka baara kɛ ni u ye
3. Flɛti min bɛ wuli
Ko min kɔlɔsira:
Drill flutes bɛ taamasiɲɛw jira minnu b’a jira ko u bɛ funteni kojugu ani ka u bɔgɔbɔ.
A sababu fɔlɔw:
RPM ka ca kojugu
Fɔli waati jan bɛ kɛ fɛn gɛlɛnw kan
Funteni bɛ caya ni puce (puce) ma bɔ ka ɲɛ
Ladilikanw minnu bɛ se ka bana kunbɛn:
Aw bɛ RPM dɔgɔya ni aw bɛ nɛgɛ gɛlɛn walima nɛgɛ gɛlɛnw sɔgɔ
Aw bɛ degun kɛ tuma bɛɛ walasa ka sɛgɛsɛgɛli waati surunya
Aw bɛ aw yɛrɛ tanga "hover drilling" ma min bɛ funteni lawuli k'a sɔrɔ a ma tigɛ
4. Furakɛyɔrɔ min bɛ wuli
Ko min kɔlɔsira:
A kun bɛ kɛ bulama ye walima ka jeni, o bɛ tigɛli seko tiɲɛ.
A sababu fɔlɔw:
Fanga tɛmɛnen min faralen don fɛn gɛlɛnw kan
Kɔrɔbɔliba min bɛ sɔrɔ RPM jugu fɛ
Funteni tiɲɛni jugumanba sɔgɔli waati
Ladilikanw minnu bɛ se ka bana kunbɛn:
Aw bɛ RPM ni nɛgɛ janya bɛn ɲɔgɔn ma
Aw bɛ aw yɛrɛ tanga fanga jiginni ma kojugu
A to drill geometry ka baara kɛ
5. Drill Bit Tilacogo
Ko min kɔlɔsira:
Drill point bɛ kari walima ka tila cɛmancɛ la.
A sababu fɔlɔw:
Fanga kojugu min bɛ kɛ bolifɛn bolituma na
Kɛlɛli barikama ni a bɛ kari nɛgɛmugu gɛlɛnw na
Sofɛrɛ ka torque spikes
Ladilikanw minnu bɛ se ka bana kunbɛn:
Aw bɛ degun sabatilen mara sɔgɔli bɛɛ kɔnɔ
Aw bɛ aw yɛrɛ tanga girinya wulibali barikamaw ma
Aw bɛ baara kɛ ni juruw ye minnu dilannen don nɛgɛ laɲininen janya kama
RPM bilasiralikan ladilikan minnu bɛ di yɛrɛ-Drilling Screws ma
RPM sugandili ɲuman nafa ka bon kosɛbɛ walasa ka funteni kojugu ni foro tiɲɛni bali. Nin danfara ninnu ye izini ka laadilikanw ye minnu bɛ tali kɛ ɲɔgɔn na:
| Nɛgɛw ka bonya | RPM min bɛ ladilikan di |
|---|---|
| A ka dɔgɔn walima a bɛ bɛn milimɛtɛrɛ 1,5 ma | 2500–3000 RPM ye |
| 1,6–3,0 mm | 1800–2500 RPM ye |
| 3,1–6,0 mm | 1200–1800 RPM ye |
| A ka bon walima a bɛ bɛn milimɛtɛrɛ 6,0 ma | 800–1200 RPM ye |
Kɔlɔsili jɔnjɔn:
RPM min ka bon, o kɔrɔ tɛ ko sɛgɛsɛgɛli teliya. Tuma caman na, teliya tɛmɛnen bɛ kɛ sababu ye ka funteni caya, ka fɛnw wuli, ka baarakɛminɛnw si hakɛ dɔgɔya.
Kuncɛli
Yɛrɛ-drilling screw dɛsɛ fanba yebaarakɛminɛn-min bɛ tali kɛ ɲɔgɔn na sanni ka kɛ fɛn dilannen-ko ye. Ni RPM kɔlɔsira, ka fanga ɲuman kɛ aksidan na, ani ka kuru dilancogo bɛn ni fɛnw gɛlɛya ye, a sigibagaw bɛ se ka dɔ bɔ kosɛbɛ drill point tiɲɛni na ani ka sirili kɛcogo ɲɛ.
Baarakɛlaw, feerekɛlaw ani izini baarakɛlaw fɛ, o dɛsɛcogo ninnu faamuyali bɛ dɛmɛ donka sigili musakaw dɔgɔya, ka dɔ bɔ baarakɛbaliya waati la, ani ka fastener baarakɛcogo janya. Sisan, a dɔnna ko sigicogo ɲumanw ye bi fɛnɲɛnamafagalanw dilanni yɔrɔ koloma ye.
