Aumsiki wegiya le-hobbingiyithuluzi lokusika elikhethekile elisetshenziswa kuisitofu segiya—inqubo yokugaya ekhiqiza amagiya anamandla, aqinile, kanye nama-worm. I-cutter (noma "i-hob") inamazinyo okusika aqinile akhiqiza kancane kancane iphrofayili yegiya ngokunyakaza okujikelezayo okuhambisanayo ne-workpiece.
1. Izinhlobo Zezicucu Zezitofu Zegiya
Ngomklamo
| Uhlobo | Incazelo | Izicelo |
| Isitofu Samazinyo Esiqondile | Amazinyo ahambisana ne-axis; ifomu elilula kakhulu. | Amagiya e-spur angenaphutha kakhulu. |
| Isitofu Samazinyo Esiyi-Helical | Amazinyo aqonde ekhoneni (njengesibungu); kungcono ukususwa kwama-chip. | Amagiya aqinile kanye nanemba kakhulu. |
| I-Chamfered Hob | Kufaka phakathi ama-chamfers kuya emaphethelweni egiya lokususa i-burr ngesikhathi sokusika. | Ukukhiqizwa kwezimoto kanye nobuningi. |
| Ihobhi Elihlanziwe | Ukuqhekeka okujulile phakathi kwamazinyo ukuze kususwe ama-chip kangcono uma kunqunywa kakhulu. | Amagiya amakhulu emodyuli (isb., ukumbiwa kwemigodi). |
Ngokwezinto Ezibalulekile
Ama-HSS (Insimbi Esheshayo) Ama-hob– Kuyonga, kusetshenziselwa izinto ezithambile (i-aluminium, ithusi).
Ama-Carbide Hobs– Kunzima, kuphila isikhathi eside, kusetshenziselwa izinsimbi eziqinile kanye nokukhiqizwa komthamo omkhulu.
Ama-Hobs Amboziwe (i-TiN, i-TiAlN)– Nciphisa ukungqubuzana, wandise isikhathi sokuphila kwamathuluzi ezintweni eziqinile.
2. Amapharamitha Abalulekile E-Gear Hob
Imojuli (M) / Iphimbo Eliyidayamitha (DP)– Kuchaza usayizi wezinyo.
Inani Lokuqala– Ukuqala okukodwa (okuvamile) vs. ukuqala okuningi (ukusika okusheshayo).
I-engela Yokucindezela (α)– Ngokuvamile20°(okuvamile) noma14.5°(izinhlelo ezindala).
Ububanzi Bangaphandle– Kuthinta ukuqina kanye nesivinini sokusika.
I-engela yokuhola– Ihambisana ne-engeli ye-helix yamagiya e-helical.
3. Isebenza Kanjani I-Gear Hobbing?
Ukujikeleza Kwezinto Zokusebenza Nezitofu– Isitofu (isisiki) kanye negiya elingenalutho kuyajikeleza ngokuvumelanisa.
Okuphakelayo kwe-Axial– Isitofu sihamba nge-axial phezu kwegiya elingenalutho ukuze sisike amazinyo kancane kancane.
Ukukhiqiza Ukunyakaza– Amazinyo ajiyile esitovini adala iphrofayili efanele yokungazibandakanyi.
Izinzuzo ze-Hobbing
✔ Amanani aphezulu okukhiqiza (uma kuqhathaniswa nokubumba noma ukugaya).
✔ Kuhle kakhuluamagiya e-spur, i-helical, kanye ne-worm.
✔ Ukuqeda ubuso okungcono kunokugcoba.
4. Ukusetshenziswa kwama-Gear Hobs
| Imboni | Sebenzisa Ikesi |
| Izimoto | Amagiya okudlulisa, umehluko. |
| Izindiza | Amagiya enjini kanye ne-actuator. |
| Izimboni | Amaphampu egiya, izinciphisi, imishini esindayo. |
| Amarobhothi | Amagiya okulawula ukunyakaza okunembile. |
5. Amathiphu Okukhetha Nokunakekela
Khetha uhlobo olufanele lwesitofu(i-HSS yezinto ezithambile, i-carbide yensimbi eqinile).
Lungiselela isivinini sokusika kanye nesilinganiso sokuphakelayo(kuya ngezinto ezibonakalayo kanye nemodyuli).
Sebenzisa isibandisiukwandisa isikhathi sokuphila kwamathuluzi (ikakhulukazi ama-carbide hobs).
Hlola ukuthi awekho yini amagugile(amazinyo aqhephukile, ukuguguleka kwezinhlangothi) ukuze kugwenywe ikhwalithi yegiya engeyinhle.
6. Abakhiqizi Abahamba Phambili Bezitofu Zegiya
I-Gleason(Ama-hob aqondile amagiya e-spiral bevel nama-cylindrical)
Amathuluzi e-LMT(Ama-HSS nama-carbide hobs asebenza kahle kakhulu)
Inkanyezi SU(Ama-hobs enziwe ngokwezifiso ezinhlelo zokusebenza ezikhethekile)
Nachi-Fujikoshi(IJapan, izitofu ezimbozwe ngendwangu zekhwalithi ephezulu)
