I-Live Tooling vs Milling yesibili kuma-Swiss Lathes

I-Live Tooling vs I-Secondary Milling ku-Swiss Lathes: Ukuthuthukisa I-CNC Precision Turning

PFT, Shenzhen

Abstract: Amalebula ohlobo lwase-Swiss afinyelela izingxenye zejiyometri eziyinkimbinkimbi kusetshenziswa amathuluzi abukhoma (amathuluzi ajikelezayo ahlanganisiwe) noma ukugaya kwesibili (imisebenzi yokugaya ngemva kokujika). Lokhu kuhlaziya kuqhathanisa izikhathi zomjikelezo, ukunemba, nezindleko zokusebenza phakathi kwazo zombili izindlela ezisuselwe ekuhlolweni komshini okulawulwayo. Imiphumela ibonisa ukuthi ukusebenzisa amathuluzi abukhoma kunciphisa isilinganiso sesikhathi somjikelezo ngo-27% futhi kuthuthukisa ukubekezelelana kwezikhundla ngo-15% ezicini ezifana nezimbobo namaflethi, nakuba utshalomali lwamathuluzi okuqala lungaphezulu ngo-40%. Ukugaya okwesibili kubonisa izindleko eziphansi zengxenye ngayinye yevolumu engaphansi kwamayunithi angu-500. Ucwaningo luphetha ngenqubo yokukhetha esekelwe engxenyeni eyinkimbinkimbi, usayizi weqoqo, nezidingo zokubekezelela.

1 Isingeniso

Ama-lathes aseSwitzerland abusa ukunemba okuphezulu, ukukhiqizwa kwezingxenye ezincane. Isinqumo esibalulekile sibandakanya ukukhetha phakathibukhoma ukusebenzisa(ukugaya/ukubhoboza emshinini) kanyeukugaya okwesibili(imisebenzi enikelwe yangemva kwenqubo). Idatha yemboni ikhombisa u-68% wabakhiqizi ukubeka phambili ukwehlisa ukusetha kwezingxenye eziyinkimbinkimbi (Smith,J. Manuf. Isayensi., 2023). Lokhu kuhlaziya kulinganisa ukuhwebelana kokusebenza kusetshenziswa idatha yemishini ye-empirical.

2 Indlela

2.1 Idizayini yokuhlola

• Izinto zokusebenza: 316L izinti zensimbi engagqwali (Ø8mm x 40mm) ezinezimbobo eziphambanayo ezingu-2x Ø2mm + 1x 3mm flat.

• Imishini:

  • I-Live Tooling:I-Tsugami SS327 (Y-axis)

  • Ukugaywa kwesibili:Hardinge Conquest ST + HA5C Indexer

• Amamethrikhi Alandelelwe: Isikhathi somjikelezo (amasekhondi), ukuhwaqazeka kwendawo (Ra µm), ukubekezelela indawo yembobo (±mm).

2.2 Ukuqoqwa kwedatha

Amaqoqo amathathu (n=izingxenye ezingu-150 ngendlela ngayinye) acutshunguliwe. I-Mitutoyo CMM ilinganise izici ezibucayi. Ukuhlaziywa kwezindleko kufaka phakathi ukuguga kwamathuluzi, abasebenzi, nokwehla kwenani lomshini.

3 Imiphumela

3.1 Ukuqhathanisa Ukusebenza

*Umfanekiso 1: Ukusebenzisa amathuluzi abukhoma kunciphisa isikhathi somjikelezo kodwa kwenyusa izindleko zamathuluzi ngengxenye ngayinye.*

3.2 Ukuhlaziya Izindleko-Izinzuzo

• Iphoyinti le-Break-Even: Ukusebenzisa amathuluzi abukhoma kubiza kakhulu kumayunithi angu-550 (Umfanekiso 2).

• Umthelela Wokunemba: Amathuluzi abukhoma asusa amaphutha okulungisa kabusha, kunciphisa ukuhluka kwe-Cpk ngo-22%.

4 Ingxoxo

Ukunciphisa Isikhathi Somjikelezo: Imisebenzi ehlanganisiwe yamathuluzi abukhoma isusa ukubambezeleka kokubamba okuyingxenye. Nokho, ukulinganiselwa kwamandla okuphotha kukhawulela ukugaya okunzima.
Imikhawulo Yezindleko: Izindleko eziphansi zokugaya zesibili zifanelana nezibonelo kodwa ziqongelela umsebenzi wokubamba.
Okushiwo Okusebenzayo: Ezingxenyeni zezokwelapha/ze-aerospace ezinokubekezelelwa okungu-±0.015mm, ukusebenzisa amathuluzi abukhoma kulungile naphezu kokutshalwa kwezimali okuphezulu kokuqala.

5 Isiphetho

Ukusebenza kwamathuluzi okubukhoma kumalebula e-Swiss kuletha isivinini esiphezulu nokunemba kwezingxenye zevolumu ephakathi ukuya kokuphezulu (>amayunithi angama-500). Ukugaya okwesibili kuhlala kusebenza kumajiyometri alula noma amaqoqo aphansi. Ucwaningo lwesikhathi esizayo kufanele luhlole ukuthuthukiswa kwendlela yamathuluzi esetshenziswa bukhoma.
