Precision Cold Drawn Honed Steel Tubing
Precision txias drawn honed (CDH) steel tubing sawv cev rau qhov kawg ntawm kev ua tau zoo thiab zoo nyob rau hauv thaj tsam ntawm seamless mechanical tubing. Nws yog cov khoom tsim tshwj xeeb tsim los rau cov ntawv thov tshwj xeeb qhov tseeb qhov tseeb, zoo tshaj qhov chaw tiav, thiab cov khoom siv kho tshuab zoo heev, feem ntau yog cov thooj voos kheej kheej hauv hydraulic thiab pneumatic systems.

Precision txias drawn honed (CDH) steel tubing sawv cev rau qhov kawg ntawm kev ua tau zoo thiab zoo nyob rau hauv thaj tsam ntawm seamless mechanical tubing. Nws yog cov khoom tsim tshwj xeeb tsim los rau cov ntawv thov tshwj xeeb qhov tseeb qhov tseeb, zoo tshaj qhov chaw tiav, thiab cov khoom siv kho tshuab zoo heev, feem ntau yog cov thooj voos kheej kheej hauv hydraulic thiab pneumatic systems.
Cov txheej txheem tsim khoom yog ob- theem ua haujlwm uas txhais tau tias nws cov yam ntxwv zoo dua. Nws pib nrog kev kos duab txias, qhov twg lub plhaub seamless steel yog rub los ntawm kev tuag ntawm chav tsev kub. Cov txheej txheem no txias- ua haujlwm cov hlau, ua kom nws lub zog tensile, yield zog, thiab hardness thaum ua tiav nruj sab nraud txoj kab uas hla (OD) thiab phab ntsa thickness kam rau ua.
Qhov thib ob tseem ceeb theem yog honing, abrasive machining txheej txheem. Lub raj xa dej txias lub taub sab hauv (ID) yog qhov tseeb- honed siv cov pob zeb sib hloov. Cov kauj ruam no ua tiav peb lub hom phiaj tseem ceeb: Ua ntej, nws muab qhov tshwj xeeb zoo nkauj thiab zoo ib yam hauv qhov chaw tiav, feem ntau ntsuas hauv micro- ntiv tes (Ra). Daim iav-zoo li qhov ua tiav yog qhov tseem ceeb rau kev txo qis kev sib txhuam thiab hnav ntawm cov ntsaws ruaj ruaj thiab pistons, ua kom muaj kev ua haujlwm zoo thiab ua haujlwm ntev. Qhov thib ob, nws ua tiav ultra-nrawm sab hauv qhov ntev thiab qhov ncaj. Thib peb, cov txheej txheem honing tsim tus ntoo khaub lig zoo tshaj -hatch nto qauv, uas yog qhov zoo rau khaws lubrication thiab ua kom yooj yim rau kev sib tsoo zoo-hauv.
Kev sib xyaw ua ke ntawm cov txheej txheem no ua rau lub raj nrog cov khoom tsis sib xws:
Zoo heev Geometric Control
Tight tolerances ntawm OD, ID, thiab phab ntsa thickness.
Superior Surface tiav
Ib tug du, honed ID nto uas txo cov kev sib txhuam thiab foob hnav.
Txhim kho Mechanical Properties
Siab zog thiab hardness los ntawm kev ua haujlwm txias.
Kev npaj tam sim rau kev siv
Cov raj feem ntau yog muab ntxuav, phosphate-coated, thiab oiled, npaj rau kev sib dhos yam tsis muaj kev siv tshuab ntxiv.
Yog li ntawd, precision CDH tubing yog cov khoom ntawm kev xaiv rau hydraulic thooj voos kheej kheej, pneumatic thooj voos kheej kheej, poob siab absorbers, linear actuators, thiab ntau yam siab - kev siv precision hauv kev lag luam xws li kev tsim kho, kev ua liaj ua teb, kev tsim khoom, thiab aerospace, qhov kev ntseeg siab thiab kev ua tau zoo tsis yog - sib tham. Nws muab lub hauv paus tseem ceeb rau kev ua haujlwm tau zoo thiab siv tau lub zog siv hluav taws xob.
