H2: Dab tsi yog Roughing End Mill

Lub roughing kawg zeb yog cov cuab yeej txiav tsim los rau kev tshem tawm cov khoom hnyav thaum pib ntawm CNC machining. Raws li lub npe qhia, nws lub luag haujlwm tseem ceeb yog "ntxhiab" tawm cov khoom, sai thiab ua tau zoo txo ​​cov khoom ua haujlwm kom ze rau - cov duab kawg. Cov cuab yeej no yog qhov tseem ceeb rau kev ua haujlwm siab - ntim, qhov ceev thiab lub zog yog qhov tseem ceeb.

Ntsiab nta

Cov Hniav ntxhib thiab Flutes: Roughing kawg mills feem ntau muaj ntau dua flutes thiab cov hniav loj, ua rau lawv tuav cov chips loj dua thiab tiv taus ntau dua. Qhov kev tsim no pab txhawb kev tshem tawm cov khoom tseem ceeb sai, ua rau nws zoo tagnrho rau cov haujlwm uas yuav tsum tau muaj cov khoom tshem tawm siab.

Cov Khoom Siv Muaj Zog: Ua los ntawm carbide lossis siab - steel ceev (HSS), roughing kawg mills yog ruaj txaus los tiv thaiv cov kev ntxhov siab hnyav uas tuaj nrog txiav los ntawm cov hlau tawv xws li hlau lossis titanium.

Kev Txiav Txim Tshwj Xeeb: Tsis zoo li cov mills tiav, roughing kawg mills muaj kev txiav thiab tsis yog - txiav txiav uas hloov pauv thaum txhua qhov hla, txo cov cua sov thiab ua kom lub neej ntev dua.

Qhov zoo ntawm Roughing End Mills

Faster Tshuag Tshem Tawm: Qhov zoo tshaj plaws yog ceev. Roughing kawg mills tuaj yeem tshem tawm cov khoom loj, uas txo cov sijhawm ua haujlwm. Piv txwv li, cov cuab yeej roughing tuaj yeem tshem tawm txog li 5 npaug ntawm cov khoom siv tib lub sijhawm piv rau cov cuab yeej ua tiav!

Kev ua tau zoo: Lawv tso cai rau koj ua haujlwm nrog cov ntaub ntawv nyuaj, ua rau lawv zoo tagnrho rau cov haujlwm hnyav -cov haujlwm hauv kev lag luam xws li aerospace lossis tsheb.

Disadvantages ntawm Roughing End Mills

Rough Surface Finish: Thaum lawv zoo heev ntawm kev tshem tawm cov khoom, lawv tawm hauv qab ntawm qhov chaw ntxhib uas feem ntau xav tau kev ua tiav ntxiv kom ua tiav qhov xav tau smoothness.

Cov cuab yeej siv siab dua: Vim qhov kev txiav txim siab hnyav, cov mills roughing hnav sai dua, tshwj xeeb tshaj yog tias tsis tau khaws cia kom zoo.

Finishing End Mill yog dab tsi?

Ib qho kawg mills yog lub cuab yeej precision tsim los rau cov theem kawg ntawm CNC machining, qhov chaw ua kom pom tseeb ntawm kev ua tiav ib tus du, siab -zoo nto tiav thiab nruj kam rau ua. Tsis zoo li cov mills roughing, uas yog siv rau kev tshem tawm cov khoom siv ntau, qhov kawg mills yog txhua yam hais txog kev ua kom zoo dua qub - coj koj qhov project los ntawm ntxhib mus rau pristine. Txawm hais tias koj tab tom ua haujlwm ntawm cov ntsiab lus tsis sib xws rau cov khoom siv hauv aerospace lossis cov khoom siv hauv tsheb, qhov kawg mills muab rau koj zoo meej polished saib.

Ntsiab nta

Cov hniav zoo nkauj thiab cov hniav sib tsoo: Cov mills tiav muaj tsawg dua, cov hniav zoo dua li cov mills. Qhov no tso cai rau kom meej, du txiav nrog cov cuab yeej me me, ua rau lawv zoo tagnrho rau kev ua tiav zoo -.

Siab dua Helix Angles: Ntau qhov kawg mills muaj ntau dua helix kaum sab xis (txog 45 degrees), uas pab tsim kom muaj kev sib tw thiab txo qis kev co. Qhov no ua rau kev ua kom huv huv thiab txhim kho lub neej ntawm cov cuab yeej.

Cov Txheej Txheem Tshwj Xeeb: Cov mills ua tiav feem ntau yog coated nrog titanium nitride (TiN) lossis lwm cov txheej tawv tawv los txhim kho lawv cov kav ntev, txo hnav, thiab txhim kho cov cua sov.

Qhov zoo ntawm Finishing End Mills

Precision thiab Zoo: Kev ua tiav mills ua tau zoo ntawm kev tsim kom zoo nkauj tiav. Piv txwv li, lawv tuaj yeem ua tiav qhov roughness tsawg li Ra 0.2 microns, zoo tagnrho rau cov khoom uas yuav tsum tau ua kom nruj.

Tight Tolerances: Cov mills no zoo meej rau cov ntawv thov uas qhov ntev thiab qhov zoo ntawm qhov chaw yog qhov tseem ceeb, xws li hauv kev lag luam aerospace lossis thaum siv cov khoom siv kho mob.

Disadvantages ntawm Finishing End Mills

Kev tshem tawm cov khoom qeeb: Thaum ua tiav cov mills ua tau zoo hauv qhov tseeb, lawv tsis tau tsim rau siab - tshem tawm cov khoom ceev. Lawv ua haujlwm qeeb dua li roughing mills thiab feem ntau yog siv tom qab cov khoom siv ntau lawm tau raug tshem tawm.

Vulnerability to Wear: Vim muaj kev txiav cov npoo zoo thiab ua haujlwm tsis zoo, cov mills tiav tuaj yeem hnav sai dua yog tias siv tsis raug, tshwj xeeb tshaj yog nyob rau hauv siab txiav loads.

Qhov sib txawv tseem ceeb ntawm Rough Milling thiab Finish Milling

Cov khoom tshem tawm tus nqi

Rough milling aims kom tshem tawm ntau cov khoom sai sai. Nyob rau hauv sib piv, tiav milling tsom rau precision, tshem tawm tsuas yog me me ntawm cov khoom nyob rau hauv ib lub sij hawm kom ua tau ib tug du nto.

Tool Tsim

Rough milling cov cuab yeej muaj coarser hniav thiab ntau flutes los txhim kho durability; cov cuab yeej milling tiav muaj cov hniav zoo dua thiab tsawg dua flutes kom ua tiav kev txiav kom huv, du.

Spindle Ceev thiab Pub Tus Nqi

Rough milling cov cuab yeej yuav tsum tau siab dua spindle speeds thiab pub tus nqi kom tshem tawm cov khoom sai. Cov cuab yeej milling tiav yuav tsum tau qis dua spindle ceev rau kev txiav meej, kom ntseeg tau siab - zoo nto tiav.

Nto tiav

Rough milling ua rau rougher nto; tag milling aims muab ib tug du nto thiab nruj tolerances.

Hom cuab yeej
