Milling Cutter Basics

Zoyambira za Milling cutter

Kodi chodula mphero ndi chiyani?

Malinga ndi akatswiri, wodula mphero ndi chida chodulira chomwe chimagwiritsidwa ntchito pogaya. Imatha kuzungulira ndikukhala ndi mano amodzi kapena angapo odula. Pa mphero, dzino lililonse amadula workpiece malipiro intermittently. Amagwiritsidwa ntchito kwambiri popanga ndege, masitepe, ma grooves, kupanga malo ndi kudula zida pamakina amphero. Malo opapatiza amapangidwa m'mbali mwake kuti apange ngodya yopumula, ndipo moyo wake umakhala wokwera chifukwa cha kudulidwa koyenera. Kumbuyo kwa chodulira mphero kumakhala ndi mitundu itatu: mzere wowongoka, wopindika ndi mzere wopindika. Misana yamizeremizere nthawi zambiri imagwiritsidwa ntchito ngati odula okhala ndi mano abwino. Ma curves ndi ma creases ali ndi mano abwinoko ndipo amatha kupirira katundu wodula kwambiri, ndipo nthawi zambiri amagwiritsidwa ntchito podula mphero.

Kodi odula mphero wamba ndi chiyani?

Cylindrical milling cutter: amagwiritsidwa ntchito popanga ndege pamakina opingasa. Mano amagawidwa pa circumference ya chodula mphero ndipo amagawidwa m'mano owongoka ndi mano ozungulira molingana ndi mawonekedwe a dzino. Malingana ndi chiwerengero cha mano, pali mitundu iwiri ya mano okhwima ndi mano abwino. Spiral dzino coarse-tooth mphero wodula ali ndi mano ochepa, mphamvu ya mano apamwamba, danga lalikulu la chip, loyenera kukonza movutikira; wodula bwino-dzino ndi woyenera kumaliza;

Wodula kumaso: amagwiritsidwa ntchito pamakina oyimirira mphero, makina amphero amaso kapena makina agantry. Nkhope zomaliza za ndegeyo ndi zozungulira zake zimakhala ndi mano ndi mano obwata komanso mano abwino. Mapangidwewo ali ndi mitundu itatu: mtundu wophatikizika, mtundu woyikapo ndi mtundu wolozera;

Mphero yomaliza: yomwe imagwiritsidwa ntchito popanga makina ndi malo oyambira. Mano ali pa nkhope yozungulira ndi kumapeto. Iwo sangakhoze kudyetsedwa mu malangizo axial pa ntchito. Pamene mphero mapeto ali mapeto dzino kudutsa pakati, akhoza axially kudyetsedwa;

M'mbali zitatu m'mphepete mphero wodula: ntchito makina grooves zosiyanasiyana ndi masitepe nkhope ndi mano mbali zonse ndi circumference;

Mphero yodula ngodya: imagwiritsidwa ntchito popera poyambira pa ngodya, onse ocheka amakona amodzi ndi awiri;

Chocheka mphero: chomwe chimagwiritsidwa ntchito popanga ma grooves akuya ndikudula zida zokhala ndi mano ochulukirapo pozungulira. Pofuna kuchepetsa mikangano ya wodulayo, pali 15'~1 ° kutsika kwachiwiri kumbali zonse ziwiri. Kuphatikiza apo, pali odula ma keyway mphero, odulira mphero, T-slot milling cutter ndi odula osiyanasiyana.

Kodi zofunika pakupanga zida zodulira za chodula mphero ndi ziti?

Zida zomwe zimagwiritsidwa ntchito popanga odulira mphero zimaphatikizapo zitsulo zothamanga kwambiri, ma alloys olimba monga tungsten-cobalt ndi titaniyamu-cobalt-based hard alloys. Zoonadi, pali zida zachitsulo zapadera zomwe zingagwiritsidwenso ntchito popanga odula mphero. Nthawi zambiri, zida zachitsulo izi Zili ndi izi:

1) Kuchita bwino kwa njira: kupanga, kukonza ndi kunola ndikosavuta;

2) Kuuma kwakukulu ndi kukana kuvala: Pa kutentha kwabwino, gawo lodula liyenera kukhala ndi kuuma kokwanira kuti lidulidwe mu workpiece; imakhala ndi kukana kwamphamvu kwambiri, chidacho sichimavala ndikuwonjezera moyo wautumiki;

3) Kutentha kwabwino kwa kutentha: chidacho chidzapanga kutentha kwakukulu panthawi yodula, makamaka pamene kuthamanga kwachangu kuli kwakukulu, kutentha kudzakhala kwakukulu kwambiri. Choncho, chidacho chiyenera kukhala ndi kutentha kwabwino, ngakhale kutentha kwambiri. Ikhoza kukhalabe yolimba kwambiri ndipo imatha kupitiriza kudula. Kuuma kwamtundu woterewu kumatchedwanso thermosetting kapena red hardness.

4) Mphamvu yayikulu komanso kulimba kwabwino: Panthawi yodula, chidacho chimayenera kukhala ndi mphamvu yayikulu, chifukwa chake chidacho chiyenera kukhala ndi mphamvu yayikulu, apo ayi chidzakhala chosavuta kuswa ndi kuwonongeka. Popeza chodulira mphero chikhoza kugwedezeka ndi kugwedezeka, chodulira mphero chiyeneranso kukhala cholimba bwino, kuti chisakhale chophweka kuchipu ndi chip.

Kodi chimachitika ndi chiyani chodulira mphero chikatha?

1. Kuchokera ku mawonekedwe a m'mphepete mwa mpeni, m'mphepete mwa mpeni uli ndi zoyera zowala;

2. Kuchokera ku mawonekedwe a chip, zipsyinjo zimakhala zowonongeka ndi zooneka ngati flake, ndipo mtundu wa chips ndi wofiirira ndi utsi chifukwa cha kutentha kwa tchipisi;

3. Njira yophera imatulutsa kugwedezeka kwakukulu ndi maphokoso achilendo;

4. Ukadaulo wa pamwamba pa workpiece ndi wosauka kwambiri, ndipo pamwamba pa ntchitoyo imakhala ndi mawanga owala okhala ndi zikwakwa kapena ma ripples;

5. Pamene mphero zitsulo ndi odula carbide mphero, kuchuluka kwa moto chifunga nthawi zambiri ntchentche;

6. Zigawo zachitsulo zogaya zokhala ndi zitsulo zothamanga kwambiri, ngati zitaziziritsidwa ndi mafuta odzola, zidzatulutsa utsi wambiri.

Pamene chodulira mphero chadutsa, chiyenera kuyimitsidwa nthawi yake kuti muwone ngati mphero yavala. Ngati kuvala kuli kochepa, nsonga yodulayo ingagwiritsidwe ntchito pogaya nsonga ndikugwiritsanso ntchito. Ngati kuvala kuli kolemetsa, kuyenera kunoledwa kuti chodula mphero chisachuluke. Valani
