Kuyini i-End Mill?

Unqenqema oluyinhloko lomshini wokugcina luwubuso obuyindilinga, kanti unqenqema lomshini wokugcina luwunqenqema lwesibili lomshini. Umshini wokugcina ongenawo unqenqema oluphakathi awukwazi ukwenza ukunyakaza kokudla eceleni kwesiqondiso se-axial somshini wokugaya. Ngokwezinga likazwelonke, ububanzi bomshini wokugcina bungu-2-50 mm, obungahlukaniswa ngezinhlobo ezimbili: amazinyo aqinile namazinyo amancane. Ububanzi obungu-2-20 buwububanzi bomshini oqondile, kanti ububanzi obungu-14-50 buwububanzi bomshini ocijile.
Izigayo zokugcina ezijwayelekile ziyatholakala ezinamazinyo aqinile nathambile. Inani lamazinyo esigayo sokugcina izinyo eliqinile lingu-3 kuya ku-4, kanti i-helix angle β inkulu; inani lamazinyo esigayo sokugcina izinyo eliqinile lingu-5 kuya ku-8, kanti i-helix angle β incane. Izinto zengxenye yokusika ziyinsimbi esheshayo, kanti i-shank iyinsimbi engu-45.

Kunezinhlobo eziningi zezicucu zokugaya, ezisetshenziselwa imishini yokugaya evamile kanye nemishini yokugaya ye-CNC ukucubungula imifantu kanye nemigqa eqondile, kanye nokucubungula imigodi, ama-core, kanye nokwakheka/imigqa engaphezulu ezindaweni zokugaya kanye nezindawo zokugaya ezibophayo.
Izigayi zokugaya ngokuvamile zihlukaniswe kanje:
1. Umsiki wokugaya ophelele oyisicaba, kokugaya okuncane noma ukugaya okuqinile, imisele yokugaya, ukususa inani elikhulu lezikhala, ukugaya okuncane kwezindiza ezincane ezivundlile noma ama-contour;

2. Umsiki wokugaya ikhala lebholaukuze kuqedwe ngokuphelele futhi kuqedwe ukugaya izindawo ezigobile; abasiki abancane bangaqeda ukugaya ama-chamfer amancane ezindaweni eziphakeme/ezindongeni eziqondile.

3. Umsiki wokugaya oyisicaba uneukuxubana, engasetshenziswa ekugayeni okungahlelekile ukuze kususwe inani elikhulu lezikhala, futhi ingagaya kahle ama-chamfer amancane ezindaweni ezincane ezisicaba (uma kuqhathaniswa nezindawo eziphakeme).

4. Ukwakha izigubhu zokugaya, kufaka phakathi abasiki be-chamfering, abasiki be-milling ababunjwe ngo-T noma abasiki be-drum, abasiki bamazinyo, kanye nabasiki be-R bangaphakathi.

5. Umsiki we-chamfering, ukuma kwesikhiphi se-chamfering kufana nokwesikhiphi, futhi kuhlukaniswe ngezinsimbi zokugaya ukuze kujikelezwe futhi kuncishiswe.

6. Umsiki omise okwe-T, umsele omise okwe-T wethini;

7. Umshini wokusika amazinyo, okhipha izimo ezahlukene zamazinyo, njengegiya.

8. Isikhiphi sesikhumba esiqinile, umshini wokusika ongahluziwe owenzelwe ukusika i-aluminium kanye ne-copper alloys, ongacutshungulwa ngokushesha.

Kunezinhlobo ezimbili zezinto ezivamile zokusika izigayo: insimbi enesivinini esikhulu kanye ne-carbide eqinisiwe. Uma kuqhathaniswa neyokuqala, eyesibili inobulukhuni obukhulu kanye namandla okusika aqinile, okungakhuphula isivinini kanye nesilinganiso sokudla, kuthuthukise umkhiqizo, kwenze umsiki angacaci, futhi kucutshungulwe izinto ezilukhuni ukushintshwa njengomshini wensimbi engagqwali/i-titanium, kodwa izindleko ziphakeme, futhi amandla okusika ashintsha ngokushesha. Uma kulula ukuphula umsiki.
