Kuchera maitiro

01
Hunhu hwekuchera
Chibooreso chinowanzova nemakona maviri makuru ekucheka, ayo anochekwa apo chibooreso chiri kutendeuka.Iyo rake Angle yebhiti yakakura uye yakakura kubva pakati peakisi kusvika kumucheto wekunze.Iyo inoswedera pedyo kune denderedzwa rekunze, iyo yakakwirira yekucheka kwebhiti iri.Iyo yekucheka kumhanya inoderera kusvika pakati, uye kucheka kwekucheka kweiyo rotary centre yebit ndeye zero.Muchinjiko wemuchinjiko wechibooreso uri padhuze neakisi yenzvimbo inotenderera, uye parutivi rake Angle yemuchinjiko mupendero yakakura, hapana nzvimbo yekushivirira chip, uye kumhanya kwekucheka kwakaderera, saka inoburitsa yakakura axial kuramba. .Kurwisana kwekucheka kunogona kuderedzwa uye kushanda kwekucheka kunogona kuvandudzwa zvakanyanya kana mucheto wecheto chepamusoro wakaputirwa mumhando A kana C muDIN1414 uye chidimbu chekucheka pedyo nechepakati axis A positive rake Angle.

Zvinoenderana nechimiro cheworkpiece, zvinhu, chimiro, basa, nezvimwewo, chibooreso chinogona kukamurwa kuva marudzi mazhinji, senge HSS drill (twist drill, group drill, flat drill), solid carbide drill, indexable shallow gole drill, gomba rakadzika. , nesting drill uye inogadziriswa musoro drill.

Kupwanya chip uye kubvisa chip
Kucheka kwebhiti kunoitwa mugomba rakamanikana, uye chip inofanira kuburitswa kuburikidza nemupendero groove yebhiti, saka iyo chip chimiro ine simba guru pakucheka kuita kwebhiti.Yakajairika chip chimiro chip, tubular chip, tsono chip, conical spiral chip, ribhoni chip, fan chip, poda chip uye zvichingodaro.
Kana iyo chip chimiro chisina kunaka, zvinotevera zvinetso zvichaitika:

① Fine chips block edge groove, anokanganisa kudhirowa, kuderedza hupenyu hwekuchera, uye kunyange kugadzira chibooreso chakatyoka (senge hupfu, fan chips, nezvimwewo);
② Machipisi marefu anoputira chibooreso, achitadzisa kuvhiyiwa, zvichikonzera kukuvadza kuchibhorani kana kuvhara mvura yekucheka mugomba (senge spiral chips, ribhoni machipisi, nezvimwewo).

Maitiro ekugadzirisa dambudziko reiyo isina kunaka chip chimiro:
① Inogona kushandiswa zvakaparadzana kana zvakabatana kuwedzera chikafu, chikafu chepakati, kugaya mupendero, chip breaker uye dzimwe nzira dzekuvandudza chip breaking uye kubvisa mhedzisiro, kubvisa matambudziko anokonzerwa nekucheka chip.
Iyo nyanzvi chip breaker drill inogona kushandiswa kuchera.Semuenzaniso, kuwedzera chip breaker blade kune groove yebit ichapwanya chip mumarara anobviswa nyore nyore.Debris inobviswa zvakanaka pamwe chete nemugero pasina kuvhara mumugero.Nekudaro, iyo nyowani chip breaker inogona kuwana yakapfava yekucheka mhedzisiro pane yechinyakare bits.

Panguva imwecheteyo, simbi yakapfupika yesimbi inoita kuti inotonhorera ienderere kune iyo drill tip zviri nyore, izvo zvinowedzera kunatsiridza kupisa kupisa mhedzisiro uye kucheka mashandiro mukuita machining.Uye nekuti iyo nyowani chip breaker inopinda nemugero rese reiyo bit, inochengeta chimiro uye basa rayo mushure mekudzokorora kugaya.Pamusoro pekuvandudzwa kwekushanda uku, zvakakosha kutaura kuti dhizaini inosimudzira kuomarara kwemuviri wekuchera uye zvakanyanya kuwedzera huwandu hwemakomba akacherwa pamberi peimwe trim.

Kunyatso chera
Iko kurongeka kwegomba kunonyanya kuumbwa neaperture saizi, kurongeka kwenzvimbo, coaxiality, kutenderera, kushata kwepamusoro uye orifice burr.
Zvinhu zvinokanganisa kurongeka kwemakomba akacherwa panguva yekuchera:

(1) Bit clamping kurongeka uye mamiriro ekucheka, senge cutter clip, kucheka kumhanya, feed, yekucheka fluid, nezvimwe;
② Bit size uye chimiro, senge kureba, mupendero chimiro, musimboti chimiro, nezvimwe;
(3) workpiece chimiro, senge orifice padivi chimiro, orifice chimiro, ukobvu, clamping mamiriro, nezvimwe.
