The Ultimate Guide to HSS Saw Blades: Precision Cutting for Demanding Application

Kumvetsetsa HSS Technology: Metallurgy Zomwe Zimapanga Kusiyana

Zitsulo za High-Speed ​​Steel (HSS) zimayimira kupita patsogolo kwaukadaulo wodula, kuphatikiza ma aloyi achitsulo ndi njira zowonjezera za tungsten (14-18%), molybdenum (5-8%), chromium (3-4.5%), vanadium (1-3%), ndi cobalt (5-10%). Chinsinsi chazitsulo chotsogolachi chimathandizira kuti masambawo asunge kuuma kwapadera pa kutentha kopitilira 600 ° C - mwayi wofunikira pomwe masamba wamba achitsulo amatha kuwonongeka mwachangu. Mosiyana ndi masamba okhazikika, mitundu ya HSS imasunga Rockwell Hardness (HRC) ya 62-67 ngakhale pansi pa kupsinjika kwambiri kwa kutentha, kumasulira molunjika pakudulira kosalekeza panthawi yayitali 1.

Shanghai Easydrill imagwiritsa ntchito njira zochizira kutentha kwa vacuum kuti ziwongolere mawonekedwe a crystalline a masamba awo a M2, M35, ndi M42 grade HSS. Njira yabwinoyi imatsimikizira kuuma kofananako kudzera mu geometry ya dzino ndikusunga kulimba koyenera m'thupi la tsamba - kukhazikika kofunikira popewa kuwonongeka kwa mano panthawi yodula kwambiri.

Ubwino Waukadaulo Zomwe Zimasintha Ntchito Zodula

1. Kukaniza Kutentha Kosagwirizana & Kuchita Zovala
   Masamba a HSS amaposa masamba okhazikika achitsulo cha kaboni ndi 3-5x muzochitika zodulira kutentha kwambiri. Kafukufuku amasonyeza kuti pamene kudula liwiro kumawonjezeka kuchokera ku 170 mm / min mpaka 220 mm / min, masamba a HSS amawonetsa 19% yokha kuvala koyambirira koyambirira poyerekeza ndi 56% kuvala mathamangitsidwe mu zida wamba - kusonyeza kukhazikika kwapamwamba kwa kutentha 1. Izi zimamasulira mwachindunji nthawi yowonjezereka ya utumiki ndi kuchepetsa nthawi yopuma.
2. Precision Surface Quality
   Kuyesa kolamuliridwa kumawonetsa kuti masamba a HSS amasunga zomaliza zapamwamba (ma Ra values) chifukwa cha kuthekera kwawo kusunga m'mbali zakuthwa. Pamene mitengo ya chakudya ikukwera kuchokera ku 425 mm / min kufika ku 550 mm / min, masamba a HSS amangowonjezera 10-14% roughness kuwonjezeka motsutsana ndi 25% + m'malo ena 1. Izi zimapangitsa kuti zikhale zofunikira kwambiri pa ntchito zomaliza muzamlengalenga ndi kupanga magalimoto.
3. Kusinthasintha Pazinthu Zonse
   Kulimba kwapadera kolimba kumathandizira kukonza bwino kwazinthu zosiyanasiyana:
   • Zitsulo: Aloyi zitsulo (<45 HRC), aluminiyamu, mkuwa, ductile chitsulo
   • Zophatikiza: CFRP, GFRP popanda delamination
   • Pulasitiki: Acrylics, nayiloni, reinforced thermoplastics
   • Wood: Mitengo yolimba, matabwa a laminated okhala ndi zomangira

Metalworking & Machinery
Masamba a HSS a Shanghai Easydrill amatsogola m'malo ochitira zitsulo pokonza zitsulo, mapaipi, ndi mbiri zotuluka. Ma geometries awo osinthika a mano (Triple Chip Grind, Alternate Top Bevel) amalepheretsa kugwedezeka kwamtundu wina akamadula machubu amipanda yopyapyala, pomwe zokutira zapadera ngati TiN zimawonjezera mafuta pakudula zitsulo zosapanga dzimbiri.

Kupanga Magalimoto
Mizere yopangira imagwiritsa ntchito masamba a pulsed-laser welded HSS kwa:

• Makina opangira gawo la injini (nodular iron castings) 1
• Kutsekedwa kwa zida zotumizira
• Kukonzekera kwa chigawo choyimitsa
  Mawonekedwe a kugwedera kwa ma blades amakhala ofunikira pakusunga kulekerera kwa ± 0.1mm mu ma saws apamwamba a RPM.

Zamlengalenga & Chitetezo
Pazitsulo za nickel zovuta (Inconel 718, Ti-6Al-4V), masamba a M42 opangidwa ndi cobalt amathamanga pazigawo zokongoletsedwa:

• Kudula Liwiro: 80-120 SFM
• Mlingo wa chakudya: 0.8-1.2 mm / dzino
• Kuzizira: 8% kupanga emulsion
  Izi zimalepheretsa kugwira ntchito molimbika pamene mukukwaniritsa Ra<1.6μm pamwamba pa mapeto ofunikira pazigawo zowuluka.

Kusankha Mulingo woyenera wa HSS Blade: Zofunikira Zofunikira

Malingaliro a Jiometry a Dzino

• Makona a Hook: +10 ° mpaka +20 ° pazitsulo zofewa; -5 ° kwa zida zowonongeka
• Kuchuluka kwa mano: 60-80 TPI kwa chubu chochepa cha khoma; 8-14 TPI ya katundu wolimba
• Mapangidwe a Gullet: Mbiri zakuya za curvilinear zochotsa bwino chip

Malangizo Okhathamiritsa Kachitidwe
Kutengera kuwunika koyeserera kwa magawo a makina 1:

1. Yang'anirani kuthamanga kwachangu (Vc) kwa moyo wa zida - 20% kuthamanga kwambiri kumayambitsa 56% kuthamangitsa
2. Sinthani kuchuluka kwa chakudya (F) pomaliza - 30% kuwonjezeka kumakweza Ra ndi 14%.
3. Kuzama kwa kudula (Dp) ndi chip load - musapitirire m'lifupi mwake × 1.2

Kulephera Kupewa Njira

• Yang'anirani kugwedezeka kwa ma harmonic kusonyeza kuwonongeka kwa dzino
• Yang'anani za micro-chipping pa 50% ya moyo wa zida
• Gwiritsani ntchito nyali za strobe kuti mutsimikizire kusasinthika kwa chip

Shanghai Easydrill: Engineering Cutting Solutions

Monga wopanga satifiketi ya ISO 9001, Shanghai Easydrill imaphatikiza ukadaulo waku Germany wopera ndi R&D wamaloko kuti apange masamba a HSS omwe amakwaniritsa miyezo ya DIN 1837B. Zofunikira zawo ndi izi:

• Mapangidwe a Mano Ovomerezeka: Ma geometri asymmetric omwe amachepetsa mphamvu zodulira ndi 20%
• Zopaka za Nano-Crystalline: Zigawo za AlCrN zokhala ndi makulidwe a 0.3μm pakuchepetsa kukangana
• Kuyesa Kukhazikika Kwamphamvu: Kuthamanga kotsimikizika kwa laser pansi pa 0.02mm pa 3000 RPM

Zogulitsa zawo zimayambira pa 80mm zonyamula ma bandsaw mpaka 650mm zowona za mafakitale, zonse zokhala ndi matupi owopsa apakompyuta komanso maupangiri a carbide opangidwa mwapadera.

Tsogolo la HSS Technology

Opanga otsogola ngati Shanghai Easydrill akukankhira malire ndi:

• Smart Blades: Ophatikizidwa ndi ma microsensor owunikira kutentha / kupsinjika mu nthawi yeniyeni
• Ma Hybrid Substrates: HSS matrix okhala ndi 12% ceramic particulates podula zida za HRC 50+
• Kupanga Zokhazikika: Kubwezeretsanso kwa tungsten ndi cobalt kotseka

Kutsiliza: Ubwino Wolondola

Masamba a HSS amakhalabe ofunikira pakupanga kwamakono komwe kumagwirizana, kuchita bwino, komanso mawonekedwe apamwamba. Pomvetsetsa zaukadaulo zomwe zimayang'anira momwe amagwirira ntchito - kuchepetsa liwiro, kuchuluka kwa chakudya kumapeto, ndi kavalidwe kavalidwe - opanga amatha kutsegulira zokolola za 30-50%. Shanghai Easydrill ikupitilizabe kupanga zida zam'mphepete mwazitsulo, ndikupereka mayankho odula omwe amasintha zokolola kukhala zopikisana.

Dziwani kusiyana kwa HSS - Lumikizanani ndi Shanghai Easydrill lero kuti mupeze malingaliro atsamba lazakuthupi ndi kukhathamiritsa kwa magawo.
