Ukuze kwandiswe isikhathi sokuphila kwesikhunta, ubulukhuni bezinto ezizonqunywa nabo buvame ukwanda.Ngakho-ke, izidingo eziphakeme zibekwe phambili empilweni yamathuluzi kanye nokusebenza kahle kokucubungula emishinini enesivinini esikhulu yezinto ezinobulukhuni obuphezulu.Imvamisa, singakhetha izigayo kumaphuzu amathathu:
1. Khetha uhlobo lokugqoka ithuluzi ngokusho kohlobo nobulukhuni be-workpiece okufanele icutshungulwe.Isibonelo, lapho ucubungula i-carbon steel nezinye izinto zokusebenza ngobulukhuni obungaphansi kwe-HRC40, i-MIRACLE40 enamathelayo evela ku-Comprehensive Materials Company ingakhethwa.Lapho ucubungula insimbi ye-alloy S, insimbi yamathuluzi nezinye izinto zokusebenza ezinobunzima obungaba ngu-HRC50, ukunamathela kwe-MIRACLE kungakhethwa.Lapho wenza ama-workpieces ngobulukhuni obuphezulu, ungakhetha ukuma kwethuluzi, i-carbide material, kanye ne-coating, konke okuyi-MIRACLE coating for high-hardness machining of high-hardness materials.
2. Khetha umumo wentamo yokusika isigayo sokuphela ngokuya ngesimo se-workpiece ezocutshungulwa.Ukuma kwentamo yesigayo sokuphela kuhlukaniswe ngohlobo olujwayelekile, uhlobo lwentamo ende kanye nohlobo lwentamo ye-tapered, engakhethwa ngokusho kokucubungula nokuma kwe-workpiece.Uhlobo lwentamo ende kanye nohlobo lwentamo ene-tapered lungasetshenziselwa ukumba okujulile, futhi i-angle yokuphazanyiswa kufanele icatshangelwe lapho ukhetha phakathi kokubili.Ngesikhathi esifanayo, uma kuqhathaniswa nohlobo olude lwentamo, i-tapered neck end mill inokuqina okuphezulu, okungathuthukisa izimo zokusika futhi kufinyelele ukunemba okuhle kwemishini.I-tapered neck end mill kufanele ikhethwe ngangokunokwenzeka.
3. Khetha izigayo zokugcina ngokunemba okuhlukile kwekhanda lebhola ngokusho kokunemba komshini.Ukunemba kwe-arc yezigayo zokugcina kuvame ukuba ngu-±10 μm, kodwa kukhona nezigayo zokugcina ezino-±5 μm, ezingakhethwa ngesikhathi sokucubungula.
