Dab tsi yog peb lub xeev ntawm qhov kawg milling cutter rau tig milling
Hauv kev tig milling compound machining, hnav lub ntsej muag tom qab ntawm qhov kawg zeb feem ntau suav nrog kev hnav ntawm lub ntsej muag tseem ceeb thiab hnav ntawm lub ntsej muag lub ntsej muag. Kev hnav ntawm cov cuab yeej tom qab yog tshwm sim los ntawm kev sib txhuam muaj zog hauv qhov chaw ua haujlwm ntawm lub cuab yeej, thiab muaj cov cim pom tseeb ntawm kev sib txhuam ntawm cov khoom siv hauv qhov chaw hnav.
1. Uniform hnav ntawm lub ntsiab thiab rear cutter ntsej muag
Thaum lub sij hawm tig thiab milling, qhov hnav ntawm lub ntsiab thiab cov cuab yeej nram qab yog qhov sib npaug ntawm qhov sib npaug ntawm cov khoom siv thaum pib ntawm kev hnav, thiab txuas ntxiv rau ntawm cov cuab yeej nram qab uas nyob ib sab mus rau tag nrho cov ntug txiav. Daim duab (a) yog daim duab schematic ntawm cov khoom siv sab nraub qaum ntawm qhov hnav. Qhov dav ntawm qhov hnav khaub ncaws no yog hu ua VB, uas yog ib qho kev ntsuas kev ntsuas kev coj ua. Kev hnav ntawm lub ntsej muag tom qab yuav ua rau kom muaj kev sib txhuam ntawm kev tig thiab milling, nce lub zog txiav, nce qhov kub thiab txo qhov ua haujlwm zoo. Daim duab (b) qhia txog qhov hnav tiag tiag ntawm lub ntsej muag tseem ceeb thiab lub ntsej muag ntawm qhov kawg zeb ntawm thawj theem hnav.
2. Hauv zos hnav ntawm lub ntsiab thiab lub ntsej muag cutter
Ntawm qhov kawg milling cutters kuaj, ib feem ntawm cov cutters muaj hnyav hnyav nyob rau hauv lub zos ntau yam ntawm lub ntsiab thiab rear cutter nto, thiab tsim nyob rau hauv no tshwj xeeb qhov chaw. Daim duab (c) qhia txog kev hnav hauv zos ntawm lub ntsiab thiab sab nraub qaum ntawm qhov nruab nrab milling cutter rau tig thiab milling. Cov qauv hnav no yog tshwm sim los ntawm kev sib txhuam ntawm cov ntug peripheral thiab qhov chaw yuav tsum tau machined ntawm lub workpiece nyob rau hauv txoj kev tig milling composite ua, thiab sib sib zog nqus grooves yog grinded. Kev hnav hauv zos ntawm cov cuab yeej nram qab feem ntau tshwm sim hauv nruab nrab thiab tom qab theem ntawm kev xa milling ua.
3. Hnav lub ntsej muag lub ntsej muag lub ntsej muag
Nyob rau hauv lem milling txheej txheem, pab txiav ntug yog lub ntsej muag kawg ntug ntawm lub kawg zeb. Vim hais tias lub workpiece kuj tig thaum lub sij hawm machining txheej txheem, kev sib cuag zaus ntawm lub flank thiab machined nto ua sai, yog li cov flank hnav nyob rau hauv txoj kev milling yog ntau hnyav dua li nyob rau hauv zoo tib yam milling. Daim duab (d) qhia txog kev hnav ntawm lub ntsej muag lub ntsej muag ntawm ob khub hauv kev xa cov milling sib xyaw ua haujlwm.
