Kev tsim cov txheej txheem ntawm tungsten carbide sib tsoo Quills: Los ntawm hmoov rau cov cuab yeej Precision

Tungsten carbide sib tsoo quills yog cov cuab yeej tseem ceeb hauv kev sib tsoo high-precision, thiab lawv qhov kev ua tau zoo tshwj xeeb yog los ntawm cov txheej txheem tsim khoom zoo. Txoj kev taug kev los ntawm micron-theem hmoov mus rau cov cuab yeej precision muaj cov txheej txheem ntawm kev tswj xyuas nruj heev.

Raw Material Proportioning thiab Mixing

Kev tsim khoom pib nrog ua tib zoo xaiv tungsten carbide hmoov thiab cobalt hmoov. Cobalt ua raws li theem binder, thiab nws cov ntsiab lus ncaj qha cuam tshuam rau cov khoom kawg qhov hardness thiab toughness. Feem ntau, cov ntsiab lus cobalt yog li ntawm 6% mus rau 12%, ua kom sib luag raws li kev thov tshwj xeeb. Cov hmoov micron-theem no ntub dej-sib xyaw hauv cov pob zeb kom ntseeg tau tias molecular-theem tsis sib xws.

Txheej txheem txheej txheem

Cov slurry sib xyaw yog txau-qhuav rau hauv cov granules dawb ntws. Tom qab ntawd, precision txias isostatic nias tshuab yog ua hauj lwm los compress cov khoom ntawm 200-300 MPa siab. Nyob rau theem no, cov duab geometric yooj yim ntawm carbide sib tsoo ncej yog tsim, tab sis lub zog tseem qis, yuav tsum tau ua ntxiv.

Sintering txheej txheem

Sintering yog cov txheej txheem tseem ceeb ntawm kev tsim khoom. Nyob rau hauv lub tshuab nqus tsev sintering furnaces, qhov kub yog precisely tswj saum toj no lub melting point ntawm cobalt (feem ntau yog 1400-1500 ° C). Thaum lub sij hawm no, lub cobalt theem melts thiab ntub cov tungsten carbide hais, tsim ib tug ntom metallurgical daim ntawv cog lus los ntawm cov kua theem sintering. Precise control of the heating curve and holding time is essential to ensure complete densification and controlled grain growth.

Precision Machining

Lub sintered dawb paug carbide sib tsoo bar nkag mus rau lub precision machining theem, uas yog ib qho tseem ceeb rau kev ua kom lub sib tsoo quill raws li kev siv cov kev cai. Benchmark machining yog thawj zaug siv ultra-precision cylindrical grinders nrog pob zeb diamond sib tsoo lub log los tsim kom muaj qhov tseeb siv axis, nrog qhov ntev ntev tswj nyob rau hauv ± 0.01 hli.

Cov txheej txheem tseem ceeb precision sib tsoo muaj xws li:

1. Cov cuab yeej shank ua: Siv cov cuab yeej ua haujlwm siab nrog cov pob zeb diamond log, suav nrog kev sib tsoo ntxhib, semi-tiav, thiab ua tiav. Kev sib tsoo ntxhib tshem tawm cov khoom siv ntau dhau, kev ua tiav ib nrab ua tiav qhov yuav tsum tau ua, thiab ua tiav kom pom qhov roughness Ra ≤ 0.2 μm. Taper lub tolerances rau HSK, CAPTO, thiab lwm yam interfaces yuav tsum nyob rau hauv ± 30 ".

2. Coolant qhov ua: Siv cov khoom sib sib zog nqus qhov drilling nrog rab phom drilling tshuab. To ensure hole wall quality, feed speed (typically 50-100 mm/min) and coolant pressure (10-15 MPa) must be precisely controlled. Qhov txoj kab uas hla qhov tseeb yuav tsum ncav cuag qib H7, nrog rau qhov tsis ncaj ncees tsis tshaj 0.02/100 mm.

3. Dynamic ntsuas: Siv cov tshuab ntsuas tshwj xeeb los kho cov khoom faib tawm los ntawm cov khoom siv symmetrically tshem tawm. Cov kev xav tau suav nrog kev ua tiav qib G2.5 qhov sib npaug nrog qhov seem tsis sib npaug tsawg dua 1 g·mm / kg ntawm qhov ua haujlwm siab tshaj plaws.

Kev soj ntsuam zoo

Kev soj ntsuam zaum kawg suav nrog kev sib koom tes ntsuas cov tshuab rau qhov ntev geometric, laser interferometers rau daim ntawv thiab txoj hauj lwm kam rau ua, ntsuas cov cav tov rau dynamic tshuav nyiaj li cas, thiab metallurgical microscopes rau cov khoom siv tshuaj ntsuam xyuas. Tsuas yog cov khoom dhau tag nrho cov kev ntsuas nruj tuaj yeem xa tuaj.

Tag nrho cov txheej txheem tsim khoom siv ntau yam thev naus laus zis suav nrog cov hmoov hlau metallurgy, precision machining, thiab kev kho cua sov. Kev tswj xyuas meej ntawm txhua theem sib koom ua ke rau qhov kev ua tau zoo tshwj xeeb ntawm tungsten carbide sib tsoo quills. Tshwj xeeb tshaj yog nyob rau hauv lub precision machining theem, kev thov ntawm ultra-nyuaj cuab yeej technology, precision ntsuas tshuab, thiab automated tswj technology kom meej micron-theem manufacturing raug.
