Cov kev tsis sib xws ntawm CNC tig yog cov cim tseem ceeb uas txiav txim siab machining raug, efficiency thiab zoo. Lawv feem ntau suav nrog cov ntsiab lus tseem ceeb xws li spindle ceev, pub tus nqi, qhov tob ntawm kev txiav, qhov chaw raug thiab cov cuab yeej tsis.
Spindle ceev (n, unit: r / min) txiav txim siab txiav ceev thiab xav tau kev sib tw nrog cov khoom thiab cov cuab yeej. Piv txwv li:
Thaum machining 45 steel, spindle ceev ntawm 800 ~ 1200 r / min yog pom zoo rau cov cuab yeej carbide;
Rau aluminium alloys, qhov ceev tuaj yeem nce mus rau 2000 ~ 3000 r / min kom ua tiav siab - ceev txiav;
Rau stainless hlau, vim nws tsis zoo thermal conductivity, qhov ceev yuav tsum tau txo los ntawm 20% ~ 30%, feem ntau tswj ntawm 600 ~ 900 r / min.
Pub tus nqi (f, unit: mm / r) cuam tshuam qhov roughness thiab ntau lawm efficiency:
Roughing: 0.3 ~ 0.8 hli / r, ua haujlwm ua ntej;
Ua tiav: 0.1 ~ 0.3 mm / r, kom ntseeg tau Ra Tsawg dua lossis sib npaug rau 1.6μm;
Rau kev txiav-tawm los yog qhov tob machining, txo rau 0.05 ~ 0.2 mm / r.
Cov ntaub ntawv sib txawv xav tau kev hloov pauv kom haum rau lawv cov yam ntxwv machining:
Carbon steel (piv txwv li, 45 # steel): Linear ceev 80 ~ 120 m / min, nrog emulsion txias;
Stainless hlau (304/316L): Linear ceev txo mus rau 50 ~ 80 m / min, siv TiAlN coated cov cuab yeej los tiv thaiv nti adhesion;
Aluminium alloy (6061): Siab- txiav ceev ntawm 150 ~ 250 m / min tuaj yeem siv kom tsis txhob ua - nce ntug.
