Thaum cov neeg feem coob hnov 'precision qhov chaw machining', lawv pom ib lub tshuab CNC pristine humming tam sim ntawd, nto qaub ncaug tawm qhov zoo meej. Qhov ntawd yog kev lag luam gloss. Qhov tseeb, qhov tseem ceeb, yog dab tsi tshwm sim hauv cov npoo - qhov kev txiav txim siab ua ntej thawj lub cuab yeej kov cov khoom lag luam, thiab kev daws teeb meem uas tshwm sim thaum, inevitably, ib yam dab tsi tsis mus rau txoj kev npaj. Nws tsis yog hais txog kev tuav lub siab ntev; Nws yog hais txog kev nkag siab tias kev kam rau ua li cas nyob hauv lub ntiaj teb tiag tiag, nyob rau hauv kev ntxhov siab, ntawm qhov kub thiab txias, hauv kev sib dhos. Ntau lub khw tau dai rau ntawm lub tshuab muaj peev xwm ntawm daim ntawv, tsis nco qab tias cov khoom siv, kev kho, cov cuab yeej txoj kev zoo, thiab txawm tias lub coolant, yog cov arbiters tiag tiag.
Lub Foundation: Nws pib nrog Casting
Koj tsis tuaj yeem tshuab precision rau hauv lub hauv paus tsis zoo. Qhov no yog qhov uas ntau qhov project, tshwj xeeb tshaj yog cov complex, mus rau sab thaum ntxov. Peb tau txais ib daim ntawv luam tawm rau lub turbine tivthaiv los yog lub valve lub cev, thiab qhov tam sim ntawd tsom mus rau lub nruj bore tolerances thiab nto finishes. Tab sis yog tias qhov pib casting muaj qhov shrinkage sab hauv, cov phab ntsa tsis sib haum, lossis cov pob tawv tawv, koj tab tom sib ntaus sib tua los ntawm qhov pib. Lub machining dhau los ua haujlwm khaws cia, tsis yog qhov tseeb.
Qhov no yog vim li cas peb mus kom ze ntawm Qingdao Qiangsenyuan Technology Co., Ltd. (QSY) yog me ntsis rov qab rau qee yam. Nrog ntau tshaj 30 xyoo nyob rau hauv casting, peb saib ib feem holistically. Rau lub siab-siab valve lub cev nyob rau hauv duplex stainless hlau, kev sib tham pib nrog cov pwm tsim rau cov peev txheej casting. Yuav ua li cas peb taw qhia ib feem hauv lub plhaub kom ntseeg tau tias muaj kev ruaj ntseg thiab txo qhov porosity hauv qhov tseem ceeb sealing qhov chaw? Qhov kev txiav txim siab ntawd, ua rau lub lis piam ua ntej machining, muaj kev cuam tshuam loj dua rau kev ua tiav cov ntaub ntawv pov thawj, qhov ruaj khov kawg ntawm qhov kawg tshaj li qhov kev hloov kho hauv feeb kawg ntawm CNC.
Kuv nco qab txog ib txoj hauj lwm rau marine twj impeller nyob rau hauv ib tug nickel-raws li alloy. Tus neeg siv khoom tuaj rau peb tom qab lwm lub khw tau tawm tsam nrog cov cuab yeej tawg thiab tsis tuaj yeem tuav qhov sib npaug specs. Qhov teeb meem tsis yog qhov kev pab cuam machining; nws yog cov nplej ntws hauv lub casting. Thawj txheej txheem foundry tsim random, coarse nplej. Peb redesigned lub gating system rau peb lub plhaub pwm txheej txheem los txhawb ib tug ntau uniform, finer grain qauv. Tam sim ntawd, lub machining tau kwv yees, cov cuab yeej siv sijhawm ntev, thiab qhov sib npaug dynamic yog txoj cai hauv spec. Cov precision qhov chaw machining tau ua tiav vim tias qhov casting tau tsim los rau nws.
Cov khoom siv tsis yog ib qho kev xaiv ntawm ib daim ntawv qhia zaub mov
Ua hauj lwm nrog tshwj xeeb alloys xws li cobalt-raws li los yog Inconel series tsis yog hais txog kev hloov mus rau ib tug ntau hnav-resistant insert. Cov khoom siv tus cwj pwm dictates txhua yam. Nws yog kev sib tham nrog hlau. Stainless hlau, piv txwv li, xav ua hauj lwm-harden. Koj mus rau hauv nrog lub teeb txiav, pub qeeb, thiab koj tuaj yeem glaze rau saum npoo, ua rau qhov kev hla dhau mus txawm nyuaj thiab ua rau lub cuab yeej puas. Koj xav tau kev ntseeg siab los txiav txim siab txaus kom tau raws li cov txheej txheem ua haujlwm nyuaj, uas yuav tsum tau ua kom nruj thiab lub tshuab nrog lub zog.
Ces muaj cua sov. Machining cov alloys no ua rau muaj kev kub ntxhov, hauv cheeb tsam. Qhov kub ntawd mus qhov twg? Feem ntau mus rau hauv lub cuab yeej, uas yog vim li cas coolant xaiv thiab daim ntawv thov yog ib qho tseem ceeb. Tab sis nws kuj mus rau hauv ib feem. Rau qhov nyias-walled seem ntawm cobalt alloy aerospace bracket, qhov thermal expansion yog tiag tiag. Koj tuaj yeem tshuab nws kom zoo meej qhov ntev ntawm 25 ° C, tab sis cov cua sov ntawm machining tau nthuav nws. Thaum nws txias rov qab rau hauv chav tshuaj ntsuam xyuas, nws tsis kam lees. Koj yuav tsum tau them nyiaj rau qhov ntawd, los ntawm kev ua kom txias lossis hauv koj qhov CAM programming. Nws yog qhov xav tias koj txhim kho lub sijhawm, saib yuav ua li cas cov chips curl thiab lawv cov xim.
Peb kawm qhov no nyuaj heev thaum ntxov nrog ib pawg ntawm cov rooj zaum Stellite. Peb machined lawv tag nrho mus rau qhov kawg ntawm qhov siab band, piv txwv li ib tug zoo meej, txias txheej txheem. CMM tau pom lawv txhua tus me ntsis qis dua tom qab thermal sib npaug. Yuav tsum khawb qhov ntau. Tam sim no, rau qhov tseem ceeb ntawm cov ntaub ntawv zoo li no, peb tsim hauv thermal offset lossis, zoo dua, siv cov txheej txheem kev soj ntsuam tom qab tswj lub voj voog txias. Nws ntxiv sijhawm, tab sis nws yog qhov txawv ntawm ib feem thiab a precision qhov.
CNC yog tus khub, Tsis yog Khawv koob
Lub allure ntawm 5-axis machining chaw yog muaj zog. Lub tswv yim hais tias koj tuaj yeem kho qhov nyuaj casting ib zaug thiab tshuab txhua qhov tshwj xeeb yog qhov tseeb. Tab sis qhov practicality txawv. Txhua zaus koj qaij lub taub hau los yog tig lub rooj, koj tab tom hloov lub vector ntawm kev txiav quab yuam, kev ua tau zoo ntawm cov dej txias, thiab qhov rigidity ntawm lub teeb. Rau qhov hnyav cam khwb cia hlau vaj tsev, uas tej zaum yuav tsis muaj teeb meem. Rau ib qho slender, tsis tiav casting ntawm 17-4 PH stainless, nws tuaj yeem ua rau chatter lossis deflection.
Qee zaum, txoj kev tsawg dua yog qhov tseeb dua. Tej zaum peb yuav xaiv ua haujlwm thib ob ntawm 3-axis zeb nrog rau kev sib koom ua ke rau cov chaw nres nkoj, vim tias qhov kev sib tw no muab kev ruaj ntseg tsis sib xws rau cov haujlwm tshwj xeeb. Lub hom phiaj yog qhov kawg ntawm kev ncaj ncees, tsis qhia tawm ntawm lub tshuab cov ntaub ntawv muaj peev xwm. Pab neeg txoj kev paub txog kev txiav txim siab qhov no-thaum twg siv 5-axis ib txhij, thaum twg los ntsuas, thaum twg siv qhov teeb tsa thib ob-yog qhov pom tsis tau. Koj tsis tuaj yeem yuav cov software ntawd.
Kuv tab tom tshuaj xyuas cov txheej txheem txheej txheem rau lwm hnub rau ib qho manifold. Cov tub ntxhais hluas engineers tau programmed ib qho zoo nkauj, siv tau ib qho teeb tsa 5-axis toolpath. Nws saib zoo meej ntawm qhov simulation. Tab sis kuv kom nws hloov nws. Ib qho ntawm cov kev ua tiav tiav yuav tau tso cov cuab yeej siv cov khoom siv nyob rau hauv qhov ze-tsav kev taw qhia, uas rau cov qib tshwj xeeb ntawm cov hlau, yuav tau txhawb nqa qhov tsis zoo ntawm lub ntsej muag sealing tseem ceeb. Peb rhuav nws rau hauv ob qho kev teeb tsa. Nws siv sijhawm ntev dua, tab sis qhov ua tiav tiav. Lub tshuab yog ib qho cuab yeej; cov txheej txheem kev paub yog cov khoom siv tes ua.
Kev Tshawb Fawb: Zaj Dab Neeg Cov Ntaub Ntawv Qhia
Dhau qhov kev tshuaj ntsuam thawj zaug yog ib yam. Nkag siab vim li cas koj dhau yog txhua yam. Peb lean hnyav rau ntawm peb CMM thiab cov ntaub ntawv profileometer nto, tab sis tsis yog rau daim ntawv hla / poob. Peb nrhiav cov qauv. Yog hais tias lub bore txoj kab uas hla ntawm ib tug series ntawm cam khwb cia hlau twj tso kua mis lub cev yog tsis tu ncua trending mus rau sab siab ntawm lub siab ntev, tab sis nyob rau hauv spec, uas yog ib tug teeb liab. Puas yog cuab yeej hnav? Ib me ntsis thermal hloov? Los yog nws yog ib tug qauv nyob rau hauv lub casting nws tus kheej-tej zaum ib tug sib xws, tsawg distortion los ntawm cov txheej txheem casting uas peb tam sim no tuaj yeem kwv yees thiab them nyiaj rau hauv CAM?
Cov ntaub ntawv tawm tswv yim voj no yog qhov tseeb qhov sib xws tau tsim. Nws kaw qhov sib txawv ntawm lub khw hauv pem teb thiab lub chaw machining. Peb tau qhia cov ntaub ntawv no nrog peb tus kheej pawg neeg ua haujlwm casting, ua rau tweaks nyob rau hauv lub plhaub pwm ci txheej txheem uas txo cov seem seem thiab ua rau lub machining ruaj khov. Thaum koj tswj hwm ob txheej txheem, koj muaj cov khoom kim heev - tsis muaj, lub luag haujlwm - siv cov ntaub ntawv los ntawm ib qho los txhim kho lwm tus.
Piv txwv li, cov ntaub ntawv los ntawm machining tshwj xeeb alloys feem ntau qhia peb cov khoom siv batches tshuab ntau npaum li cas. Qhov intel rov qab mus rau peb cov khoom siv. Nws yog ib theem ntawm kev koom ua ke uas tsuas yog ua tau thaum machining tsis pom raws li ib qho kev pabcuam standalone, tab sis raws li ib theem ntawm ib feem ntawm lub neej voj voog. Qhov no yog lub tswv yim peb tau tsim ntawm QSY dhau peb xyoo lawm, thiab nws tau nthuav dav hauv peb txoj hauv kev tsi.com. Lub hom phiaj tsis yog tsuas yog ua ib feem los luam tawm hnub no, tab sis kom nkag siab txog cov txheej txheem kom tob uas peb tuaj yeem ua kom nws zoo dua, thiab kwv yees ntau dua, tag kis.
Qhov zoo txaus ntxiab
Qhov kev sib tw loj tshaj plaws hauv precision qhov chaw machining tsis yog ib txwm technical; nws feem ntau yog kev lag luam. Lub siab los txo tus nqi ib feem yog qhov loj heev. Thiab ib txwm muaj qhov taw tes uas qhov zoo txaus - nws dhau QC, nws haum (feem ntau), tus neeg siv khoom yuav tsis pom. Tab sis yog tus ntxiab. Hauv cov ntawv thov zoo li cov uas siv cov cobalt-raws li alloys peb feem ntau ua haujlwm nrog-xav tias cov tshuab siv roj lossis cov khoom siv ua haujlwm siab-zoo txaus tsis ua haujlwm. Nws ua tsis tau qeeb, kim, thiab txaus ntshai.
Kev thawb rov qab rau qhov no yuav tsum muaj lub suab meej. Nws txhais tau hais tias qee zaum qhia rau tus neeg siv khoom tias lawv qhov kev thov ua siab ntev rau qhov tsis tseem ceeb yog qhov tsis tsim nyog them 20% ntau dua, lossis cov khoom siv sib txawv yuav ua rau lawv ua tau zoo dua rau lawv daim ntawv thov tiag tiag. Nws yog hais txog kev ua tus koom tes tsim khoom, tsis yog tus neeg muag khoom xwb. Qhov no yog qhov uas 30 xyoo ntawm cov ntsiab lus tseem ceeb. Peb tau pom yuav ua li cas cov khoom tsis ua haujlwm hauv thaj teb, thiab qhov ntawd qhia tias peb hais kom lawv ua li cas.
Thaum kawg, precision machining yog kev ntseeg siab. Tus neeg siv khoom tso siab rau peb kom nkag siab txog qhov yuav tsum tau hais tsis tau - lub neej qaug zog, lub voj voog thermal, cov khoom sib dhos - uas tsis yog ntawm daim duab tab sis sau rau hauv daim ntawv thov. Peb khwv tau qhov kev ntseeg siab los ntawm kev qhia peb txoj haujlwm, los ntawm kev piav qhia vim li cas tom qab kev xaiv tus txheej txheem, thiab los ntawm kev muaj keeb kwm casting, cov ntaub ntawv pov thawj, thiab tag nrho traceability rov qab. Qhov ntawd yog cov khoom tiag. Lub tshuab ua haujlwm tsuas yog cov pov thawj lub cev xwb.
