Kev siv cov khoom siv granite hauv cov ntawv luam tawm Circuit Board (PCB) drilling thiab milling tshuab yog qhov tshwm sim vim nws qhov kev co zoo heev damping muaj peev xwm thiab siab rigidity. Txawm li cas los xij, ib qho ntawm cov teeb meem loj uas cov tuam txhab ntsib yog qhov teeb meem ntawm thermal deformation uas tuaj yeem tshwm sim thaum lub sij hawm machining.
Thermal deformation yog tshwm sim los ntawm qhov kub ntawm cov granite ntsiab vim yog kev sib txhuam tsim los ntawm cov cuab yeej txiav thaum lub sij hawm drilling los yog milling txheej txheem. Qhov kub thiab txias ua rau granite nthuav, ua rau muaj kev hloov pauv ntawm nws qhov ntev thiab cov duab. Qhov no tuaj yeem ua rau kev ua haujlwm tsis raug thiab thaum kawg, PCBs tsis raug.
Nov yog qee txoj hauv kev los txo cov thermal deformation ntawm granite ntsiab hauv PCB drilling thiab milling tshuab:
1. Siv coolant - Siv lub coolant thaum lub sij hawm machining txheej txheem yuav pab txo qhov kub ntawm lub granite caij, yog li txwv nws expansion vim thermal deformation. Lub coolant tseem yuav pab txhawb lub neej ntawm cov cuab yeej, ua rau kom zoo dua ntawm machining.
2. Siv high-speed spindles - High-speed spindles tsim muaj kev sib txhuam tsawg dua cov uas tsis muaj qhov ceev, uas txhais tau hais tias muaj cua sov tsawg dua thaum lub sij hawm machining. Qhov no ua rau txo qis thermal deformation ntawm granite caij.
3. Siv ntau qhov kev hla - Tsis txhob sim ua kom tiav cov txheej txheem machining hauv ib qho dhau los, nws raug nquahu kom siv ntau qhov hla. Qhov no yuav tso cai rau cov khoom siv granite kom txias ntawm kev hla, yog li txo nws qhov kub thiab txo cov thermal deformation.
4. Siv cov cuab yeej precision - Siv cov cuab yeej precision, xws li pob zeb diamond-tipped cov cuab yeej txiav, yuav pab txo cov cua sov tsim thaum lub sijhawm ua haujlwm. Qhov no yuav ua rau tsawg dua thermal deformation ntawm granite caij.
5. Siv thermal tswj qhov system - Lub thermal tswj system tuaj yeem ntsia tau los tswj qhov kub ntawm cov khoom granite thaum lub sijhawm machining. Cov txheej txheem no yuav pab tswj qhov kub ntawm cov khoom granite ntawm qib sib xws, yog li txo cov thermal deformation.
Hauv kev xaus, cov ntsiab lus granite yog qhov kev xaiv zoo tshaj plaws rau PCB drilling thiab milling tshuab vim lawv cov kev vibration zoo dua thiab muaj zog rigidity. Txawm li cas los xij, qhov teeb meem ntawm thermal deformation tuaj yeem tshwm sim thaum lub sijhawm machining, ua rau kev ua haujlwm tsis raug thiab tsis raug PCBs. Los ntawm kev ua raws li cov txheej txheem saum toj no, cov tuam txhab lag luam tuaj yeem txo cov thermal deformation ntawm granite ntsiab lus, uas ua rau muaj qhov tseeb thiab zoo PCBs.
