I-Choice Of Lathe Indexable Blade (CNC Blade)

Ngemuva kokuthola umdwebo we-workpiece, qala ukhethe i-indexable blade enesimo esifanele ngokuvumelana nezidingo zomdwebo. Ngokuvamile, i-lathe isetshenziselwa ukuguqula indilinga yangaphandle kanye nomgodi ongaphakathi, ukusika nokusika umsele, bese uphendulela intambo. Ukukhethwa kwe-blade kunqunywa ngokuvumelana nezimo ezithile zokucubungula ubuchwepheshe. Ngokuvamile, ama-blades anokuhlukahluka okuphezulu kanye nemiphetho yokusika ngaphezulu kwe-blade efanayo kufanele kukhethwe. Khetha usayizi omkhudlwana wokuphenduka okungalungile kanye nosayizi omncane wokuphenduka okuhle nokuncane. Ngokwezidingo zobuchwepheshe, sinquma umumo we-blade odingekayo, ubude bonqenqema lokusika, i-tip arc, ubukhulu be-blade, i-blade back angle kanye nokunemba kwe-blade.

一. Khetha umumo we-blade

1. I-blade yendilinga yangaphandleS-shape: imiphetho emine yokusika, enonqenqema olufushane (bheka ububanzi obufanayo bomjikelezo wokusika wangaphakathi), amandla aphezulu wephuzu lethuluzi, elisetshenziselwa ikakhulukazi ama-75 ° kanye nama-45 ° amathuluzi okujika, futhi asetshenziselwa ukucubungula ngokusebenzisa imbobo kumathuluzi embobo yangaphakathi.

I-T-shape: imiphetho emithathu yokusika, umkhawulo omude wokusika namandla aphansi wethiphu. I-blade ene-axiliary deflection angle ivame ukusetshenziswa ku-lathe evamile ukuze kuthuthukiswe amandla ithiphu. Ikakhulukazi esetshenziswa 90 ° turning amathuluzi. Ithuluzi lokuguqula imbobo yangaphakathi lisetshenziselwa ikakhulukazi ukukhanda izimbobo eziyizimpumputhe nezimbobo zesinyathelo.

Umumo C: kunezinhlobo ezimbili zama-engeli abukhali. Amandla amathiphu amabili we-engeli ecijile engu-100 ° aphakeme, ngokuvamile enziwa ithuluzi elijikayo elingu-75 °, elisetshenziselwa ukuguqula indilinga yangaphandle nobuso bokugcina. Amandla emiphetho emibili ye-engeli ecijile engu-80 ° aphakeme, angasetshenziswa ukucubungula ubuso bokuphela noma indawo eyi-cylindrical ngaphandle kokushintsha ithuluzi. Ithuluzi lokuguqula imbobo yangaphakathi ngokuvamile lisetshenziselwa ukucubungula imbobo yesinyathelo.

Ukuma kwe-R: unqenqema oluyindilinga, olusetshenziselwa ukukhanda indawo ekhethekile ye-arc, izinga eliphezulu lokusebenzisa i-blade, kodwa amandla amakhulu e-radial.

Umumo we-W: imiphetho emithathu yokusika futhi emfushane, i-engeli ebukhali engu-80 °, amandla aphezulu, ikakhulukazi asetshenziselwa ukukhanda indawo eyisilinda kanye nendawo yesinyathelo ku-lathe evamile.

I-D-shape: imiphetho emibili yokusika yinde, i-engeli enqenqemeni yokusika ingu-55 ° futhi amandla onqenqema lokusika aphansi, okusetshenziselwa ikakhulukazi ukucubungula iphrofayili. Lapho wenza ithuluzi lokuguqula i-93 °, i-angle yokusika akufanele ibe mkhulu kuno-27 ° - 30 °; lapho wenza ithuluzi lokuguqula elingu-62.5 °, i-angle yokusika akufanele ibe nkulu kuno-57 ° - 60 °, engasetshenziselwa umgodi wesinyathelo nokuhlanza impande engajulile lapho kucutshungulwa imbobo yangaphakathi.

Umumo we-V: imiphetho emibili yokusika nobude, i-engeli ebukhali engu-35 °, amandla aphansi, asetshenziselwa ukwenza iphrofayela. Lapho wenza ithuluzi lokuguqula i-93 °, i-angle yokusika akufanele ibe mkhulu kuno-50 °; lapho wenza ithuluzi lokuguqula i-72.5 °, i-angle yokusika akufanele ibe mkhulu kuno-70 °; lapho wenza ithuluzi lokuphenduka elingu-107.5 °, i-engeli yokusika akufanele ibe nkulu kuno-35 °.

2. Izindwani zokusika nokugxusha:

1) i-blade yokusika:

Ku-CNC lathe, i-blade yokusika ivamise ukusetshenziselwa ukucindezela i-chip breaking groove shape ngqo. Ingenza ama-chips ashwabene futhi awonakele eceleni, asikwe kalula nangokwethembeka. Ngaphezu kwalokho, ine-engeli enkulu yokuphambuka eseceleni kanye ne-engeli yangemuva, ukushisa okuncane okusika, impilo ende yesevisi kanye nentengo ephezulu.

2) i-grooving blade: ngokuvamile, i-blade yokusika isetshenziselwa ukusika i-groove ejulile, futhi i-blade yokwakha isetshenziselwa ukusika i-groove engajulile, njengokulandelayo: i-grooving blade, i-flat grooving blade, i-strip grooving blade, i-arc yokuhlanza izinyathelo. i-root groove blade. Lawa ma-blade anobude obuphezulu bokunemba kobubanzi be-groove.

3. I-thread blade: I-L-shaped blade ivame ukusetshenziswa, engase ibe kabusha futhi ingabizi, kodwa ayikwazi ukusika phezulu kwezinyo. Intambo enokunemba okuphezulu kokusika idinga ukusebenzisa i-blade enokugaya okuhle kwephrofayili. Ngenxa yokuthi intambo yangaphakathi neyangaphandle inobukhulu obuhlukahlukene bephrofayela, ihlukaniswe ngama-thread blades angaphakathi nangaphandle. I-pitch yabo igxilile futhi ingasikwa ngaphandle komqhele. Njenge-clampingIndlela, ingahlukaniswa ngezinhlobo ezimbili: enye iyinsingo engenamgodi, eboshwe ngokucindezela phezulu. Lapho ucubungula izinto ezine-plasticity ephezulu, le blade nayo idinga ukwengeza ipuleti le-baffle; enye iyinsingo enembobo yokubopha kanye ne-chip breaking groove, eboshwe ngesikulufu seplamu esinembobo yokucindezela.

二. Ubude bokusika

Ubude bonqenqema obunqunyiwe: buzokhethwa ngokusho kohlaka lwangemuva. Ngokuvamile, ubude bonqenqema lokusika lwensingo ye-groove kufanele bube ≥ izikhathi ezingu-1.5 zokusalungiswa okungemuva, futhi ubude bonqenqema lokusika lwensingo evaliwe buzoba ≥ izikhathi ezingu-2 zokusalungiswa kwangemuva.

三. ithiphu arc

I-Tip arc: inqobo nje uma ukuqina kuvunyelwe ukuphenduka okungalungile, i-tip arc radius enkulu ingasetshenziswa ngokusemandleni akho, kuyilapho i-arc radius encane ngokuvamile isetshenziselwa ukuphenduka okuhle. Kodwa-ke, lapho ukuqina kuvunyelwe, kufanele futhi kukhethwe kunani elikhulu, futhi irediyasi yendilinga ecindezelwe evame ukusetshenziswa ingu-0.4; 0.8; 1.2; 2.4, njll.

四. ukujiya kwe-blade

Ukushuba kwe-Blade: isimiso sokukhetha ukwenza i-blade ibe namandla anele okuthwala amandla okusika, okuvame ukukhethwa ngokusho kokuphakelayo kwangemuva kanye nokudla. Isibonelo, amanye ama-ceramic blades adinga ukukhetha ama-blade aminyene.

五. i-back angle ye-blade

I-Blade back angle: evame ukusetshenziswa:

0 ° ikhodi n;

5 ° ikhodi B;

7 ° ikhodi C;

11 ° ikhodi P.

0 ° i-engeli yangemuva ngokuvamile isetshenziselwa ukujika okumaholo nokuqeda, 5 °; 7 °; 11 °, imvamisa isetshenziselwa ukuqeda isigamu, ukuphenduka kokuqeda, ukwenza iphrofayili kanye nokwenza izimbobo zangaphakathi.

六. ukunemba kwe-blade

Ukunemba kwe-blade: kunezinhlobo eziyi-16 zokunemba ezishiwo nguhulumeni zama-blade indexable, phakathi kwazo izinhlobo eziyisi-6 zilungele ukujika amathuluzi, ikhodi ithi h, e, G, m, N, u, h iphezulu kakhulu, u okuphansi kakhulu, u-u usetshenziselwa ukwenza ama-rough kanye ne-semi finish machining ye-lathe evamile, uM usetshenziselwa i-CNC lathe noma u-m usetshenziselwa i-CNC lathe, kanti u-G usetshenziselwa izinga eliphezulu.

Ngemuva kwezinyathelo ezingenhla, sinqume ngokuyisisekelo ukuthi yiluphi uhlobo lwe-blade okufanele lusetshenziswe. Esinyathelweni esilandelayo, sidinga ukuqhubekela phambili sihlola amasampula e-elekthronikhi abakhiqizi be-blade, futhi ekugcineni sinqume uhlobo lwe-blade okufanele lusetshenziswe ngokuya ngezinto kanye nokunemba okufanele kusetshenzwe.
