Kev tsim cov txheej txheem ntawm Auger khoom

Kev tsim cov auger laum cov khoom suav nrog cov kauj ruam tseem ceeb xws li xaiv cov khoom siv, kev siv thev naus laus zis, kev kho cua sov, thiab kev tshuaj xyuas zoo. Cov ntaub ntawv tseem ceeb feem ntau yog siab- steel ceev (HSS, xws li M2 lossis M35 steel, muaj 5-10% tungsten thiab 4-8% molybdenum) lossis cemented carbide (WC-Co, cobalt ntsiab lus 6%-15%). Kev kho ua ntej muaj xws li forging (1100℃-1200 degree) thiab annealing (hardness HRC25-30). Cov txheej txheem machining suav nrog CNC tshuab dhos txoj kev (qhov siab kam rau ua ± 0.02mm), nrog lub kaum sab xis hloov kho raws li daim ntawv thov: 30℃-35℃rau ntoo laum khoom (ntxhiab nti tshem tawm), 35℃-40℃rau hlau laum khoom (txhim kho rigidity), thiab 25℃drills (nruab nrab-30 degree). Kev kho cua sov muaj xws li quenching (1220℃-1280 degree, hardness HRC58-62) thiab tempering (3 zaug ntawm 560 degree). Txheej (xws li TiN lossis TiAlN, thickness 2-5μm) tuaj yeem txhim kho hnav tsis kam los ntawm ntau tshaj 200%. Kev tshuaj xyuas zoo suav nrog kev sib tsoo (apex lub kaum sab xis 118℃± 2 degree, tshem tawm lub kaum sab xis 8℃-12 degree) thiab dynamic ntsuas ntsuas (qhov seem tsis txaus qis dua lossis sib npaug li 0.5g·mm). Cov ntawv thov tshwj xeeb xws li qhov sib sib zog nqus qhov xyaum yuav tsum muaj qhov cua txias sab hauv (txoj kab uas hla 1-1.5mm, lub siab txias txias Ntau dua lossis sib npaug li 3MPa), thiab cov khoom siv sib xyaw ua ke siv ntau yam khoom siv segmented tsim.
