1. Dimensional raug
Dimensional raug yog lub hauv paus thiab ib qho ntawm cov kev xav tau tseem ceeb hauv CNC precision machining. Nws yog hais txog qhov sib txawv ntawm qhov loj me ntawm qhov machined thiab qhov tsim loj, feem ntau hais txog kev kam rau siab. CNC machining muaj peev xwm ua tiav qhov siab qhov tseeb qhov tseeb, feem ntau rau kev ua siab ntev ntawm ±0.01mm lossis tsawg dua, thiab hauv qee qhov kev siv siab, txawm tias nyob hauv micron ntau. Qhov kev xav tau siab tshaj plaws no ua kom ntseeg tau tias cov khoom haum zoo sib xws thaum sib dhos thiab siv, txo cov kev ua haujlwm poob thiab kev nyab xeeb vim qhov sib txawv ntawm qhov sib txawv.
Txhawm rau kom ua tiav qhov kev tswj xyuas qhov ntsuas siab, CNC tshuab cov cuab yeej yuav tsum muaj cov cuab yeej tswj tau siab, cov tshuab xa mus, thiab ntsuas tshuab. Nyob rau tib lub sijhawm, tus neeg teb xov tooj yuav tsum tau paub zoo hauv kev ua haujlwm ntawm lub tshuab cuab yeej, suav nrog cov kev pabcuam kho, kev ua yuam kev, thiab lwm yam., kom ntseeg tau tias kev ruaj ntseg thiab raug ntawm cov txheej txheem machining.
2. Nto roughness
Nto roughness yog ib qho tseem ceeb qhia los ntsuas qhov zoo ntawm qhov chaw, uas muaj kev cuam tshuam tseem ceeb ntawm kev sib txhuam kev ua haujlwm, hnav tsis kam, corrosion kuj thiab lwm yam. CNC machining yuav tsum muaj peev xwm tswj tau qhov roughness ntawm qhov chaw kom tau raws li cov kev cai tshwj xeeb. Feem ntau, qhov roughness saum npoo tuaj yeem ncav cuag Ra {{0}}.8 μm lossis tsawg dua, thiab qee zaum txawm qis dua Ra 0.4 μm. Qhov no du nto tsis tsuas yog txhim khu kev zoo nkauj ntawm ib feem, tab sis kuj txhim kho nws cov kev pab cuam lub neej thiab kev ua tau zoo stability.
Yuav kom ua tiav qhov zoo tshaj plaws nto roughness, CNC machining txheej txheem yuav tsum tau xaiv cov cuab yeej zoo, txiav cov ntaub ntawv thiab cov khoom txias. Nyob rau tib lub sijhawm, yam xws li kev tswj kev vibration, spindle ceev thiab pub tus nqi ntawm lub tshuab kuj tuaj yeem cuam tshuam rau ntawm qhov chaw roughness. Yog li, cov xwm txheej no yuav tsum tau txiav txim siab ua tiav hauv cov txheej txheem ua kom tau txais qhov zoo ntawm [cov lus nkag siab].
3. Geometric raug
Geometric raug suav nrog parallelism, perpendicularity, concentricity, symmetry, thiab lwm yam, uas cuam tshuam txog kev sib raug zoo ntawm qhov chaw ntawm qhov chaw. CNC machining yuav tsum tau lav qhov tseeb geometric ntawm cov khoom kom ntseeg tau tias cov khoom tuaj yeem ua haujlwm ruaj khov thaum sib dhos thiab siv. Feem ntau hais lus, qhov sib npaug thiab qhov sib npaug yuav tsum nyob hauv 0.02mm, thiab cov coaxiality thiab symmetry kuj tseem nruj heev.
Txhawm rau kom ua tiav qhov kev tswj hwm geometric siab, cov cuab yeej ua haujlwm siab thiab qhov chaw yuav tsum tau muaj nyob rau hauv CNC machining txheej txheem los xyuas kom meej qhov ruaj khov ntawm workpiece thaum lub sij hawm machining txheej txheem. Nyob rau tib lub sijhawm, programmers yuav tsum tau teeb tsa lub cuab yeej thiab txiav txim siab txog yam xws li cov cuab yeej them nyiaj thiab thermal deformation kom txo tau qhov sib txuam ntawm qhov yuam kev hauv cov txheej txheem machining. Tsis tas li ntawd, tsis tu ncua calibration ntawm lub tshuab tsis, xws li straightness, verticality, thiab lwm yam, kuj yog ib tug tseem ceeb kauj ruam nyob rau hauv kev tswj geometric raug.
Plaub, kev siv cov khoom siv thiab kev ua haujlwm zoo
Hauv CNC precision machining, cov khoom siv thiab kev ua haujlwm zoo yog qhov tseem ceeb sib npaug. Cov txheej txheem machining zoo tuaj yeem tsis tsuas yog txo cov nqi, tab sis kuj txo cov voj voog ntau lawm thiab txhim kho qhov nrawm ntawm cov tuam txhab tuaj yeem teb rau kev lag luam. Txhawm rau ua tiav qhov no, kev ua kom zoo ntawm kev txiav cov ntaub ntawv, kev siv cov cuab yeej tsim nyog npaj, thiab kev siv cov txheej txheem CNC siab heev rau kev teem sijhawm ntse yog qhov tseem ceeb. Tsis tas li ntawd, los ntawm kev taw qhia ntawm ib qho automated loading thiab unloading system thiab
