Chii chinonzi milling cutter?

Kubva pakuona kwehunyanzvi, chigayo chekucheka chishandiso chinoshandiswa pakugaya. Inogona kutenderera uye ine rimwe kana kupfuura mazino ekucheka. Panguva yekugaya, zino rega rega rinocheka iyo workpiece mvumo nguva nenguva. Inonyanya kushandiswa mukugadzira ndege, nhanho, grooves, kuumba nzvimbo uye kucheka workpieces pamilling muchina. Nyika nhete inoumbwa padivi kuti iite kona yekuyamura, uye hupenyu hwayo hwakakwira nekuda kweiyo inonzwisisika yekucheka kona. Kuseri kwepitch milling cutter ine mafomu matatu: mutsara wakatwasuka, curve uye peta mutsara. Mitsara misana inowanzoshandiswa kune yakanaka-mazino ekupedzisa kucheka. Macurves uye creases ane simba remazino ari nani uye anogona kutsungirira mitoro inorema yekucheka, uye anowanzo shandiswa kune akacheka-mazino anocheka.

Ndeapi anowanzo cheka kugaya?

Cylindrical milling cutter: inoshandiswa kugadzira ndege pamichina yakachinjika yekugaya. Mazino akagoverwa padenderedzwa rekucheka kwekucheka uye akakamurwa kuita mazino akatwasuka uye mazino anotenderera zvichienderana nechimiro chezino. Maererano nenhamba yemazino, kune marudzi maviri emazino akakasharara nemazino matete. Spiral mazino akacheka-meno anocheka ane mazino mashoma, akakwirira mazino simba, hombe chip nzvimbo, yakakodzera rough machining; fine-tooth milling cutter yakakodzera kupedzisa;

Face milling cutter: inoshandiswa kumichina yekugaya yakatwasuka, muchina wekugaya kumeso kana magantry ekugaya. Ndege inopera zviso uye denderedzwa rine mazino uye mazino akakasharara nemazino akanaka. Chimiro chine marudzi matatu: akabatanidzwa mhando, isa mhando uye indexable mhando;

End mill: inoshandiswa muchina grooves uye nhanho nzvimbo. Mazino ari padenderedzwa uye kumagumo zviso. Havagone kudyiswa mune axial direction panguva yekushanda. Kana chigayo chekupedzisira chine zino rekupedzisira richipfuura nepakati, rinogona kudyiswa axially;

Three-sided edge milling cutter: inoshandiswa muchina akasiyana grooves uye nhanho zviso zvine mazino mativi ese uye denderedzwa;

Angle milling cutter: yaishandiswa kukuya groove nekona, ese ari single-angle uye maviri-angle milling cutters;

Saw blade milling cutter: inoshandiswa muchina yakadzika grooves uye kucheka maworkpiece ane mazino akawanda padenderedzwa. Kuti uderedze kona yekukwenya kweanocheka, pane 15'~1 ° kuderera kwechipiri pamativi ese. Pamusoro pezvo, kune keyway milling cutters, dovetail milling cutters, T-slot milling cutters uye akasiyana ekugadzira ekucheka.

Ndezvipi zvinodikanwa zvekugadzira zvinhu zvekucheka chikamu chemilling cutter?

Zvishandiso zvakajairika zvekugadzira zvigayo zvinocheka zvinosanganisira simbi dzakasimba, dzakaoma alloys senge tungsten-cobalt uye titanium-cobalt-based hard alloys. Ehe, kune mamwe masimbi akakosha anogona kushandiswa kugadzira milling cutters. Kazhinji, izvi simbi zvinhu Zvine zvinotevera zvinhu:

1) Kuita kwakanaka kwemaitiro: kugadzira, kugadzirisa uye kurodza zviri nyore;

2) Kuomarara kwepamusoro uye kushomeka kwekupfeka: Pakupisa kwakajairika, chikamu chekucheka chinofanira kunge chine kuomarara kwakakwana kucheka mukati mechishandiso; ine yakakwirira kupfeka kusagadzikana, chishandiso hachipfeki uye chinowedzera hupenyu hwebasa;

3) Kupisa kwakanaka kwekupisa: chigadziro chichaunza kupisa kwakawanda panguva yekucheka, kunyanya kana kukurumidza kwekucheka kwakakwirira, kutonhora kuchave kwakanyanya. Naizvozvo, mudziyo wekushandisa unofanirwa kuve wakanaka kupisa kupisa, kunyangwe pakupisa kwakanyanya. Inogona kuchengetedza kuoma kwepamusoro uye inokwanisa kuramba ichicheka. Idzi rudzi rwekuoma kwekushisa kwakanyanya kunonziwo thermosetting kana kuomarara kutsvuku.

4) Kusimba kwepamusoro uye kusimba kwakanaka: Panguva yekucheka, chishandiso chinofanirwa kutakura simba rakakura, saka mudziyo unofanirwa kuve nesimba rakawanda, zvikasadaro zvichave nyore kutyora uye kukanganisa. Sezvo chigayo chekucheka chiri pasi pekukatyamadzwa uye kudedera, iyo milling cutter zvinhuinofanirawo kuva nekuoma kwakanaka, kuitira kuti zvisave nyore chip uye chip.

Chii chinoitika mushure mekunge mucheki weguyo wamiswa?

1. Kubva pachimiro chemupendero webanga, mupendero webanga une muchena wakajeka;

2. Kubva pachimiro chechipsi, machipisi anova akaoma uye akafanana-flake, uye ruvara rwemachipisi rwepepuru uye utsi nekuda kwekukwira kwekushisa kwemachipisi;

3. Kugayo kunoburitsa kuzunguzika kwakanyanya uye ruzha rusina kujairika;

4. Kushata kwechiso chebasa rakashata zvikuru, uye pamusoro pebasa rekushanda rine mavara akajeka ane majeko ejeko kana ripples;

5. Paunenge uchikuya zvidimbu zvesimbi ne carbide milling cutters, mhute yakawanda yemoto inowanzobhururuka;

6. Masimbi ekugaya ane simbi anocheka-kumhanya, kana akatonhodzwa nemafuta ekuzora, anoburitsa utsi hwakawanda.

Kana iyo milling cutter ikapfuura, inofanirwa kumiswa nenguva kuti itarise kupera kweguyo. Kana kupfeka kuri kudiki, kuchekwa kwekucheka kunogona kushandiswa kukuya kumucheto wobva washandiswa zvakare. Kana kupfeka kwacho kuchirema, kunofanirwa kurodzwa kudzivirira chigayo kuti chisanyanya kuwandisa. Pfeka
