Koj puas tau saib ntawm carbide ntxig thiab xav paub tias cov ntawv thiab cov lej txhais li cas? Kev nkag siab yuav ua li cas txheeb xyuas qhov ntsuas qhov ntsuas tau yog qhov tseem ceeb rau txhua tus kws kho tshuab thiab CNC tus neeg teb xov tooj.
Txhua qhov ntxig ua raws li tus qauv ISO coding system uas qhia txog nws cov duab, lub kaum sab xis, qhov siab, qib, thiab txheej. Thaum koj nkag siab yuav ua li cas txhais cov qauv no, xaiv qhov tseeb ntxig rau kev tig, milling, lossis drilling ua nrawm thiab meej.
Cov lus qhia no yuav pab koj txiav txim siab ntxig cov cim cov kauj ruam los ntawm kauj ruam, yog li koj tuaj yeem txhim kho qhov tseeb ntawm machining, txuas lub neej ntawm cov cuab yeej, thiab txo cov nqi tsim khoom. Cia peb yooj yim ntxig kev txheeb xyuas thiab ua kom cov cuab yeej xaiv tau yooj yim dua puas tau!
Dab tsi yog Indexable Inserts?
Indexable insertsmuab precision, efficiency, thiab nqi -effectiveness, ua rau lawv ib tug lub hauv paus ntawm kev ua hauj lwm machining niaj hnub. Indexable inserts yog cov lus qhia hloov pauv tau siv hauv CNC tig, milling, thiab drilling cuab yeej. Es tsis txhob rov kho cov cuab yeej zoo, cov tshuab ua haujlwm tsuas tuaj yeem tig lossis hloov qhov ntxig thaum txiav ntug hnav tawm - txuag lub sijhawm thiab nqi.
Cov ntawv ntxig no feem ntau yog tsim los ntawm carbide, ceramic, CBN, lossis PCD, thiab ruaj khov rau cov cuab yeej siv screws lossis clamps. Txhua qhov ntxig nta ntau qhov txiav, tso cai rau rov siv tau zoo thiab ua haujlwm zoo ib yam.
Piv nrog cov khoom kawg mills los yog xyaum, indexable inserts muab tau zoo heev. Lawv tuaj yeem ua tau ntau yam khoom siv - los ntawm cov hlau thiab cam khwb cia hlau mus rau stainless hlau thiab txhuas - tsuas yog los ntawm kev sib hloov cov hom lossis qib.
Nkag siab ISO Insert Identification Codes
Txhua qhov indexable ntxig yog cim nrog cov cim tshwj xeeb uas ua raws li ISO 1832 tus qauv, uas txhais nws cov geometry, qhov loj me, thiab cov yam ntxwv. Thaum xub thawj siab ib muag, cov lej no - zoo li CNMG120408 - yuav zoo li tsis meej pem, tab sis thaum koj nkag siab lawv, lawv dhau los ua cov cuab yeej muaj zog - kev qhia xaiv.
Cia peb rhuav tshem qhov piv txwv CNMG120408:
C – Ntxig puab (C=80℃pob zeb diamond puab)
N – Lub kaum sab xis nyem (N=0℃nyem)
M – chav kawm kam rau ua (M=nruab nrab precision)
G - Hom chipbreaker thiab clamping style
12 - Ntxig qhov loj (txiav ntug ntev hauv mm × 1/10)
04 - Ntxig thickness (hauv mm × 1/10)
08 – Nose radius (hauv mm × 1/100)
Hom ntawv coding no pab cov kws kho tshuab sai sai txheeb xyuas qhov zoo ntxig rau lawv daim ntawv thov - seb nws yog tig, milling, lossis drilling.
Ntxig Shapes thiab lawv daim ntawv thov
Cov duab ntawm ib qho indexable insert yog ib qho tseem ceeb tshaj plaws hauv kev txiav txim siab nws txoj kev txiav. Txhua daim duab muab qhov sib npaug sib txawv ntawm lub zog, kev nkag tau yooj yim, thiab qhov chaw tiav - ua rau nws yog qhov tseem ceeb los xaiv qhov zoo rau koj cov kev xav tau machining.
Nov yog cov duab ntxig ntau tshaj plaws thiab lawv cov ntawv thov raug:
| Cov duab | Code | Lub kaum sab xis | Kev siv yam |
| C | 80℃pob zeb diamond | Muaj zog, ntau yam | General tig thiab tig |
| D | 55℃pob zeb diamond | Ntse, meej | Finishing thiab profile |
| T | 60℃Daim duab peb sab | Peb txiav ntug | Lub teeb rau nruab nrab txiav |
| S | 90℃square | Ntug muaj zog heev | Hnyav roughing thiab cuam tshuam kev txiav |
| R | Hloov | Smooth txiav | Copy tig thiab contouring |
W (80℃trigon) inserts muab lub zog thiab kev nkag tau yooj yim, ua rau lawv muaj lwm txoj hauv kev zoo rau C- hom inserts.
V (35℃pob zeb diamond) inserts muab zoo heev ncav cuag rau nruj profiles tab sis tsis tshua muaj zog nyob rau hauv hnyav load.
Feem ntau, cov duab muaj zog (xws li S lossis C) yog qhov zoo tagnrho rau kev ntxhib los mos, thaum cov duab zoo nkauj (xws li D lossis V) zoo dua rau kev ua tiav. Xaiv qhov zoo ntxig ntxig zoo pab tswj kev ruaj ntseg, txo kev co, thiab txhim kho qhov zoo.
Relief Angles thiab Clearance Designations
Lub kaum sab xis - tseem hu ua lub kaum sab xis tshem tawm - txiav txim siab seb muaj pes tsawg qhov chaw nyob nruab nrab ntawm qhov ntxig lub flank thiab cov khoom ua haujlwm. Nws plays lub luag haujlwm tseem ceeb hauv chip flow, heat dissipation, thiab nto tiav. Xaiv lub kaum sab xis kom raug ua kom zoo dua txiav thiab tiv thaiv kev sib tsoo lossis cov cuab yeej puas.
Nyob rau hauv ISO insert identification system, tsab ntawv thib ob ntawm tus lej sawv cev rau lub kaum sab xis:
| Code | Lub kaum sab xis | Kev piav qhia | Daim ntawv thov |
| N | 0 degree | Tsis muaj clearance; muaj zog ntug | Hnyav roughing, tsis zoo rake cov cuab yeej |
| P | 11 degree | Txheem clearance | General tig thiab milling |
| C | 7 degree | Lub teeb clearance | Kev ua tiav thiab ib nrab-ua tiav |
| A | 3 degree | Me me clearance | Lub teeb tiav, cov cuab yeej me me |
| B | 5 degree | Nruab nrab clearance | Nruab nrab txiav loads |
Cov kaum me me (0℃-7 degree) muab cov ntug zog ntau dua thiab ruaj khov rau cov ntaub ntawv nyuaj lossis cuam tshuam.
Cov ces kaum loj dua (11℃lossis ntau dua) txo qhov txiav quab yuam thiab txhim kho qhov zoo, zoo tagnrho rau cov ntaub ntawv mos xws li txhuas lossis tooj dag.
Kev nkag siab txog cov npe no pab cov kws kho tshuab ua kom zoo tshaj qhov kev txiav thiab xaiv qhov zoo ntxig geometry rau txhua qhov haujlwm.
Ntxig Tolerances, Clamping, thiab Chipbreakers
Kev xaiv kom zoo ntawm cov ntxig rau qhov siab, txoj kev clamping, thiab hom chipbreaker yog qhov tseem ceeb rau kev ua haujlwm zoo thiab ua haujlwm zoo ib yam.
Ntxig Tolerances
ISO txhais cov chav kawm kam rau ua uas qhia qhov tseeb ntawm qhov ntxig qhov ntev thiab cov ces kaum.
Cov chav kawm: M (medium), G (general), H (siab).
Siab siab siab inserts yog siv nyob rau hauv kev ua tiav qhov kev tswj kom nruj yog qhov tseem ceeb.
Txoj Kev Clamping
Inserts yog tuav nyob rau hauv lub toolholder siv screws, clamps, wedges, los yog sab saum toj locks.
Kev kho kom raug clamping kom ruaj khov thiab txo kev co, tiv thaiv kev hnav ntxov ntxov.
Rau siab -ceev lossis hnyav- lub luag haujlwm machining, sab saum toj clamps lossis wedge clamps yog nyiam vim muaj kev ruaj ntseg zoo dua.
Chipbreakers
Chipbreakers tswj chip tsim thiab khiav tawm.
Hom muaj xws li qhov zoo, qhov tsis zoo, thiab cov duab tshwj xeeb rau cov khoom sib txawv thiab kev txiav.
Kev xaiv chipbreaker kom zoo txo cov cua sov, tiv thaiv cov nti entanglement, thiab txhim kho qhov chaw tiav.
Los ntawm kev nkag siab yuav ua li cas kam rau ua, clamping, thiab chipbreaker hom sib cuam tshuam, machinists tuaj yeem ua kom lub neej zoo tshaj plaws, tswj qhov tseeb ntawm machining, thiab ua kom zoo rau kev txiav.
Ntxig Qib thiab Txheej Txheej
Xaiv txoj kev ntxig qib thiab txheej txheej yog qhov tseem ceeb rau kev ua tiav kev ua haujlwm zoo tshaj plaws thiab cov cuab yeej siv lub neej. Cov qib qhia cov khoom muaj pes tsawg leeg ntawm cov ntxig, thaum coatings txhim khu kev hnav tsis kam, kub kam rau siab, thiab txo kev sib txhuam.
Common Insert Materials
