Phau Ntawv Qhia Qhov Kawg rau HSS Pom Hniav: Precision Txiav rau Kev Thov Cov Ntawv Thov

Nkag siab HSS Technology: Metallurgy Uas Qhov Sib Txawv

High-Speed ​​Steel (HSS) pom cov hniav sawv cev rau kev nce qib hauv kev siv tshuab txiav, sib txuas cov hlau alloys nrog cov tswv yim ntxiv ntawm tungsten (14-18%), molybdenum (5-8%), chromium (3-4.5%), vanadium (1-3%), thiab cobalt (5-10%). Daim ntawv qhia zoo tshaj plaws ntawm metallurgical daim ntawv qhia no ua rau cov hniav tuaj yeem khaws qhov tshwj xeeb hardness ntawm qhov kub siab tshaj 600 ° C - qhov txiaj ntsig tseem ceeb uas cov pa roj carbon zoo tib yam yuav sai sai degrade. Tsis zoo li cov qauv hniav, HSS variants tuav lub Rockwell Hardness (HRC) ntawm 62-67 txawm tias nyob rau hauv qhov kev ntxhov siab heev, txhais ncaj qha rau kev txiav cov kev ua tau zoo thaum lub sijhawm ua haujlwm ntev 1.

Shanghai Easydrill leverages precisely tswj lub tshuab nqus tsev kho cua sov txheej txheem los optimize lub crystalline qauv ntawm lawv M2, M35, thiab M42 qib HSS hniav. Qhov kev ua kom zoo zoo no ua kom muaj qhov sib txawv ntawm qhov sib txawv ntawm cov hniav geometry thaum tswj qhov tsim nyog toughness nyob rau hauv cov hniav lub cev - qhov sib npaug tseem ceeb rau kev tiv thaiv kev puas tsuaj ntawm cov hniav thaum lub sij hawm ua haujlwm siab.

Technical Advantages uas hloov cov kev txiav txiav

1. Unmatched Thaum tshav kub kub Resistance & Wear Performance
   HSS cov hniav ua tau zoo tshaj cov pa roj carbon steel hniav los ntawm 3-5x nyob rau hauv high-temperature txiav scenarios. Kev tshawb fawb qhia tias thaum txiav ceev nce los ntawm 170 mm / min mus rau 220 mm / min, HSS cov hniav pom tsuas yog 19% siab dua thawj coj piv rau 56% hnav acceleration nyob rau hauv cov cuab yeej zoo tib yam - qhia superior thermal stability 1. Qhov no ncaj qha txhais mus rau ncua kev pab cuam ncua sij hawm thiab txo downtime.
2. Precision Nto Zoo
   Kev tswj xyuas qhia tau hais tias HSS cov hniav muaj qhov ua tiav zoo tshaj plaws (Ra qhov tseem ceeb) vim tias lawv muaj peev xwm khaws cov npoo ntse. Thaum pub tus nqi nce los ntawm 425 mm / min mus rau 550 mm / min, HSS cov hniav qhia tsuas yog 10-14% roughness nce piv rau 25% + nyob rau hauv lwm txoj kev 1. Qhov no ua rau lawv indispensable rau finish-critical applications nyob rau hauv aerospace thiab automotive manufacturing.
3. Versatility hla cov ntaub ntawv
   Qhov tshwj xeeb hardness-toughness tshuav nyiaj li cas ua kom muaj txiaj ntsig zoo ntawm cov khoom sib txawv:
   • Hlau: Hlau alloys (<45 HRC), txhuas, tooj dag, hlau hlau
   • Composites: CFRP, GFRP yam tsis muaj delamination
   • Plastics: Acrylics, nylon, reinforced thermoplastics
   • Ntoo: Hardwoods, laminated boards nrog embedded fasteners

Cov ntawv thov muaj nyob qhov twg HSS Blades Excel

Hlau & Machinery
Shanghai Easydrill's HSS cov hniav yog thawj hauv cov chaw pabcuam hlau ua cov qauv hlau, cov kav dej, thiab extruded profiles. Lawv cov hniav sib txawv (Triple Chip Grind, Alternate Top Bevel) tiv thaiv kev sib raug zoo ntawm kev co thaum txiav nyias-walled tubing, thaum tshwj xeeb coatings zoo li TiN txhawb lubricity hauv stainless hlau txiav.

Automotive Manufacturing
Cov kab ntau lawm siv pulsed-laser welded HSS hniav rau:

• Cav Cheebtsam machining (nodular hlau castings) 1
• Transmission iav blanking
• Suspension Cheebtsam fabrication
  Cov hniav 'kev co damping cov yam ntxwv ua pov thawj tseem ceeb rau kev tswj hwm ± 0.1 hli qhov ntev ntev nyob rau hauv high-RPM automated saws.

Aerospace & Kws muaj txuj ci
Rau qhov tseem ceeb nickel alloys (Inconel 718, Ti-6Al-4V), cobalt-enriched M42 hniav khiav ntawm optimized tsis:

• Txiav ceev: 80-120 SFM
• Pub tus nqi: 0.8-1.2 hli / hniav
• Coolant: 8% hluavtaws emulsion
  Qhov no tiv thaiv kev ua hauj lwm hardening thaum ua tiav Ra<1.6μm nto finishes yuav tsum tau rau ya davhlau Cheebtsam.

Xaiv qhov Optimal HSS Hniav: Cov Ntsiab Cai

Tooth Geometry Kev txiav txim siab
