Cov teeb meem dab tsi yuav tshwm sim thaum lub sij hawm xov machining tom qab kev daws teeb meem?
Tso lus
Peb tau mus dhau txoj kev kho kev daws teeb meem thiab xov machining sij hawm rau kub khiav stainless hlau bolts ua ntej. Nov yog cov teeb meem uas yuav tshwm sim thaum lub sij hawm xov machining tom qab kev daws teeb meem:
Uncontrolled Machining Accuracy: Yog hais tias lub machining ua tiav thaum lub workpiece tsis txias txaus, cov khoom nyob rau hauv lub xeev ntawm siab ductility thiab threads yog nquag deformation thiab springback, ua rau ib tug precision theem qis dua 6H thiab tsis ua raws li qhov precision installation yuav tsum tau ntawm cov kub runners.
Residual stress accumulation: Premature machining creates a high quantity of new machining stress. The sluggish release of stress under long-term operation circumstances of the hot runner (>200 degree) ua rau deformation ntawm lub bolts, thiab thaum kawg ua rau lub loosening, stripping thiab tawg ntawm lub installation torque.
Deg zoo tsis xws luag: Lub workpiece yog mos mos tom qab kev kho mob, yog li nws yog ib qho yooj yim mus ua lub cuab tam sticking thaum lub sij hawm machining. Qhov no ua rau burrs thiab khawb ntawm qhov chaw ntawm cov xov. Qhov no txo qhov smoothness ntawm cov xov haum.
Risk of Grain Damage: Yog hais tias cov nplej muaj ntau heev thaum lub sij hawm kev kho mob, cov xov txiav kev ua hauj lwm yuav ua puas lub grain ciam qauv, drastic txo tus creep tsis kam ntawm lub ntsia liaj qhov rooj thiab txo lub neej kev pab cuam ntawm kub kub. Cov teeb meem uas tau hais tseg no tuaj yeem zam tau zoo los ntawm kev tswj hwm lub sijhawm ua haujlwm ntawm lub sijhawm, txhawm rau xyuas kom meej tias qhov kev ua tau zoo kawg ntawm cov kub khiav bolts tuaj yeem phim cov qauv.
