Milling cutters inoshandiswa zvakanyanya. Iwe unonzwisisa chaizvo chimiro chevanocheka cheka? Ngatizvitsvage kubudikidza nechinyorwa nhasi.
1. Main geometric angles ye indexable milling cutters
Chigayo chine kona inotungamira nemakona maviri ake, imwe inonzi axial rake angle uye imwe inonzi radial rake angle.
The radial rake angle angle γf uye axial rake angle γp. Iyo radial rake angle γf inonyanya kukanganisa simba rekucheka; iyo axial rake angle γp inokanganisa kuumbwa kwemachipisi uye kutungamira kweaxial simba. Kana γp iri yakanaka kukosha, machipi anobhururuka kubva kune machining maitiro. noodle.
Rake angle (rake face contact surface)
Negative rake angle: yesimbi, simbi alloys, Stainless simbi, cast iron.
Positive rake angle: inoshandiswa mune viscous zvinhu uye mamwe epamusoro-tembiricha alloys.
Kona yepakati yepakati: inoshandiswa kugadzira shinda, grooving, profiling uye kugadzira mapanga.
Shandisa negative rake angles pese pazvinogoneka.
2. Milling cutter geometry
1. positive angle -positive angle
Kucheka kwakareruka uye kwakatsetseka, asi iyo yekucheka kumucheto simba haina kunaka. Inokodzera kugadzirisa zvinhu zvakapfava uye simbi isina tsvina, simbi inodzivirira kupisa, simbi yakajairwa uye simbi yakakandwa, etc. Iyi fomu inofanirwa kusarudzwa kana paine maturusi emagetsi mashoma-simba, kusakwana kuomarara kweiyo process system, uye mipendero yakavakirwa.
Advantage:
+ kucheka kwakatsetseka
+ Smooth chip evacuation
+ kunaka kwepamusoro
Zvakaipa:
- Kucheka kumucheto simba
- Haikodzeri kucheka kuonana
- Iyo workpiece inoparadzaniswa kubva patafura yemuchina
2. Kongiro isina kunaka – Negative angle
Iine simba rinopikisa rinopikisa uye rinoshandisa mashizha asina kunaka, akakodzera kugadzirwa kwesimbi yakakandwa, simbi yakakandwa uye yakakwirira-kuoma, yakakwirira-simba resimbi.
Nekudaro, kugaya kunodya rakawanda simba uye kunoda yakanakisa process system rigidity.
Advantage:
+ kucheka kwesimba simba
+ Kubudirira
+ Sunda workpiece kutafura yemuchina
Zvakaipa:
- Simba guru rekucheka
- Chip blocking
Xinfa CNC zvishandiso zvine hunhu hwemhando yakanaka uye mutengo wakaderera. Kuti uwane ruzivo, ndapota shanya:

3. Positive angle - negative angle
Iyo yekucheka ine simba yakasimba yekupikisa uye inopinza. Inokodzera kugadzirisa simbi, simbi yakakandwa uye simbi yakakandwa. Mhedzisiro yacho zvakare iri nani kana uchikuya nemahombekombe makuru.
Advantage:
+ Smooth chip evacuation
+ mauto akanaka ekucheka
+ Yakasiyana-siyana yekushandisa
4. Milling cutter pitch
1) Mazino akaomeswa: chikafu chinomhanya-mhanya, simba guru rekugaya, nzvimbo duku yechip.
2) Mazino akajairwa: akajairwa kukurumidza kwekudya, simba rekugaya uye chip nzvimbo.
3) Mazino akaomarara: kudya kwakaderera-kumhanya, simba diki rekugaya, hombe chip nzvimbo.
Kana chigayo chekucheka chisina kuisirwa chakasarudzika chekupukuta, kushata kwepamusoro kunoenderana nekuti chikafu chega chega chinodarika hupamhi hwendege yekupukuta.
Muenzaniso: Slot Milling & Contour Milling
Nhamba yemeno:
•Mazino mashoma kana akajairwa ekugaya slot (kuchengetedza)
•Mazino akakora ekugadzira contour milling (productivity)
Nguva yekutumira: Nov-01-2023
