Chii chinonzi End Mill?

Iyo huru yekucheka kwekupedzisira kweguyo ndeye cylindrical surface, uye iyo yekucheka pamucheto wekupedzisira ndiyo yechipiri yekucheka.Chigayo chisina mupendero wepakati hachikwanise kuita kufambisa kwekudya pamwe neaxial kutungamira kwechigayo chekucheka.Zvinoenderana nechiyero chenyika, dhayamita yeguyo yekupedzisira ndeye 2-50 mm, iyo inogona kukamurwa kuva marudzi maviri: mazino akaoma uye mazino akanaka.Iyo dhayamita ye2-20 ndiyo mutsara weshank yakatwasuka, uye dhayamita ye14-50 ndiyo mutsara wetapered shank.
Standard end mills anowanikwa ane mazino akakasharara uye akanaka.Nhamba yemazino e-coarse-tooth end mill ndeye 3 kusvika ku4, uye helix angle β yakakura;nhamba yemazino eguyo rekupedzisira-mazino ndeye 5 kusvika ku8, uye helix angle β iduku.Zvinhu zvechikamu chekucheka isimbi yakakwirira, uye shank ndeye 45 simbi.

Kune akawanda maumbirwo ezvigayo zvekucheka, ayo anoshandiswa kune akajairwa milling muchina uye CNC milling muchina kugadzirisa grooves uye yakatwasuka contours, uye kugadzirisa cavities, cores, uye pamusoro maumbirwo / contours pakugaya uye kufinha machining nzvimbo.
Milling cutters inowanzo kamurwa kuita:
1. Flat end milling cutter, yekugadzira milling kana rough milling, milling grooves, kubvisa huwandu hwakawanda hwema blanks, kugaya kwakanaka kwendege diki dzakachinjika kana contours;

2. Bhora mhino yekugayaye semi-kupedzisa uye kupedzisa kugaya kwenzvimbo dzakakomberedzwa;vateki vadiki vanogona kupedzisa kukuya machamfer madiki pamawere / madziro akatwasuka.

3. The flat end milling cutter inechamfering, iyo inogona kushandiswa kugayo yakakasharara kubvisa huwandu hukuru hwema blanks, uye inogona zvakare kugaya zvinyoro zvidiki panzvimbo dzakati sandarara (zvinei nepamusoro pemawere).

4. Kugadzira milling cutters, zvinosanganisira kucheka kwechamfering, T-shaped milling cutters kana madhiramu ekucheka, mazino anocheka, uye emukati maR ekucheka.

5. Chamfering cutter, maumbirwo emucheki anochekeresa akafanana neanochera, uye anokamurwa kuva vacheki veguyo kuti vatenderedze uye vapenye.

6. T-shaped cutter, chigayo chakaita saT groove;

7. Mucheki wemazino, kugaya zvimiro zvakasiyana-siyana, semagiya.

8. Mucheka weganda wakakasharara, rough milling cutter yakagadzirirwa kucheka aluminium nemhangura alloys, iyo inogona kugadziriswa nokukurumidza.

Pane zvinhu zviviri zvakajairika zvekucheka zvigayo: high-speed simbi uye simende carbide.Kana ichienzaniswa neyekare, iyo yekupedzisira ine kuoma kwakanyanya uye simba rakasimba rekucheka, iro rinogona kuwedzera kukurumidza uye chiyero chekudya, kuvandudza kubereka, kuita kuti mucheki asave pachena, uye kugadzirisa zvakaoma-ku-muchina zvinhu zvakadai sesimbi isina tsvina / titanium alloy, asi. mari yacho yakakwirira, uye simba rekucheka rinoshanduka nokukurumidza.Muchiitiko che nyore kuputsa mucheki.
