Milling cutter basics

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 milling cutters.

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, simba rezino rakakwirira, nzvimbo huru yechip, inokodzera rough machining; fine-tooth milling cutter yakakodzera kupedzisa;

Face milling cutter: inoshandiswa kumichina yekugaya yakatwasuka, muchina wekugaya kumeso kana gantry milling machine. 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. Ivo havagone kudyiswa munzira yeaxial 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 pane denderedzwa. Kuti uderedze kona yekukwenya kweanocheka, pane 15'~1 ° yechipiri kuderera kumativi ese. Pamusoro pezvo, kune keyway milling cutters, dovetail milling cutters, T-slot milling cutters uye akasiyana ekugadzira ekucheka.

Ndezvipi zvinodiwa pakugadzirwa kwezvinhu zvekucheka chikamu chekucheka kwekucheka?

Zvishandiso zvakajairika zvekugadzira zvigayo zvinocheka zvinosanganisira high-speed tool steels, hard 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 chakaomarara chakakwana kuti chicheke muworkpiece; 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: Munguva yekucheka, chishandiso chinofanirwa kutakura simba rakakura rekuita, saka chishandiso chinofanirwa kunge chine simba rakawanda, zvikasadaro zvichave nyore kutyora uye kukanganisa. Sezvo chigayo chekucheka chiri pasi pekukatyamadzwa uye kuzunguzika, chigayo chekucheka chinofanirwawo kuve nekusimba 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 pakuumbwa kwechiputi, machipisi anova akaoma uye akafanana-flake, uye ruvara rwechiputi rwepepuru uye utsi nekuda kwekukwira kwekushisa kwezviputi;

3. Kugayo kunoburitsa kudengenyeka kwakanyanya uye ruzha rusina kujairika;

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

5. Pakugaya simbi zvidimbu zvine carbide milling cutters, hombe yemhute yemoto inowanzobhururuka;

6. Masimbi ekugaya ane high-speed steel milling cutters, kana akatonhodzwa nemafuta ekuzora, anoburitsa hutsi 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 mucheki weguyo kuti asanyanya kuwandisa. Pfeka
