The Ultimate Guide to HSS Saw Blades: Precision Cutting for Demaking Applications

Ho utloisisa Theknoloji ea HSS: Metallurgy e Etsang Phapano

Litšepe tsa High-Speed ​​Steel (HSS) li emela tsoelo-pele ea theknoloji ea ho seha, ho kopanya li-alloys tsa tšepe le litlatsetso tsa leano la tungsten (14-18%), molybdenum (5-8%), chromium (3-4.5%), vanadium (1-3%), le cobalt (5-10%). Recipe ena e rarahaneng ea metallurgical e nolofalletsa li-blade ho boloka boima bo ikhethang mochesong o fetang 600 ° C - e leng molemo o moholo moo mahare a tloaelehileng a tšepe a ka senyehang kapele. Ho fapana le li-blade tse tloaelehileng, mefuta ea HSS e boloka Rockwell Hardness (HRC) ea 62-67 leha e le tlas'a khatello e matla ea mocheso, e fetolelang ka kotloloho ts'ebetsong e tsitsitseng ea ho itšeha nakong ea ts'ebetso e telele.

Shanghai Easydrill e sebelisa mekhoa ea ho phekola mocheso oa vacuum ka nepo ho ntlafatsa sebopeho sa kristale sa li-blade tsa HSS tsa M2, M35, le M42 tsa sehlopha sa HSS. Mokhoa ona o hlokolosi o tiisa ho ajoa ha boima bo tšoanang ka geometry ea leino ha o ntse o boloka boima bo hlokahalang 'meleng oa lehare - ho leka-lekana ho bohlokoa ho thibela ho senyeha ha leino nakong ea ts'ebetso e phahameng ea ho itšeha.

Melemo ea Setsebi e Fetolang Ts'ebetso ea ho Seha

1. Ho se Bapisoe ke Mocheso le Ts'ebetso ea Wear
   Li-blade tsa HSS li feta matla a tloaelehileng a tšepe ea carbon ka 3-5x maemong a sehang a mocheso o phahameng. Lipatlisiso li bontša hore ha lebelo la ho itšeha le eketseha ho tloha ho 170 mm / min ho ea ho 220 mm / min, li-blades tsa HSS li bontša feela 19% e phahameng ea ho apara qalong ha e bapisoa le 56% ea ho potlakisa ho apara lisebelisoa tse tloaelehileng - ho bontša botsitso bo phahameng ba mocheso 1. Sena se fetolela ka ho toba linakong tse atolositsoeng tsa tšebeletso le ho fokotsa nako ea ho fokotsa nako.
2. Precision Surface Quality
   Teko e laoloang e senola hore li-blade tsa HSS li boloka li-finals tse holimo (litekanyetso tsa Ra) ka lebaka la bokhoni ba tsona ba ho boloka likarolo tse bohale. Ha litefiso tsa phepo li eketseha ho tloha ho 425 mm/min ho ea ho 550 mm/min, li-blades tsa HSS li bontša feela keketseho e boima ea 10-14% khahlano le 25%+ ka mekhoa e meng ea 1. Sena se etsa hore e be tsa bohlokoa haholo bakeng sa lits'ebetso tsa bohlokoahali tsa tlhahiso ea lifofane le likoloi.
3. Mefuta-futa ea Lintho Tse Ngata
   Ho leka-lekana ho thata-thata ho thusa ho sebetsana ka katleho le lisebelisoa tse fapaneng:
   • Metals: Lisebelisoa tsa tšepe (<45 HRC), aluminium, koporo, tšepe ea ductile
   • Likarolo: CFRP, GFRP ntle le delamination
   • Plastiki: Acrylics, nylon, thermoplastics e matlafalitsoeng
   • Patsi: Lifate tse thata, mapolanka a laminated a nang le li-fasteners tse kentsoeng

Lisebelisoa tsa indasteri Moo HSS Blades Excel

Mosebetsi oa tšepe le Mechini
Li-blade tsa HSS tsa Shanghai Easydrill li atile litsing tsa lits'ebeletso tsa tšepe tse sebetsanang le litšepe tsa sebopeho, lipeipi le li-profiles tse pharalletseng. Li-geometri tsa bona tsa meno (Triple Chip Grind, Alternate Top Bevel) li thibela ho thothomela ha li-harmonic ha li seha li-tubing tse nang le mabota a masesaane, ha liphahlo tse khethehileng joalo ka TiN li matlafatsa lubricity ho seha ka tšepe e sa hloekang.

Ho Etsa Likoloi
Mehala ea tlhahiso e sebelisa mahare a HSS a pulsed-laser bakeng sa:

• Ho sebetsa ka likarolo tsa enjine (li-nodular iron castings) 1
• Ho koaloa ha lisebelisoa tsa phetisetso
• Ho fanyeha karolo ea ho fanyeha
  Litšobotsi tsa "vibration damping" tsa "vibration" li iponahatsa li le bohlokoa bakeng sa ho boloka mamello ea ± 0.1mm ho lisaha tse ikemetseng tsa RPM.

Sefofane le Tšireletso
Bakeng sa li-alloys tsa nickel tse bohlokoa (Inconel 718, Ti-6Al-4V), li-blade tsa M42 tse ntlafalitsoeng ka cobalt li sebetsa ka mekhahlelo e ntlafalitsoeng:

• Ho itšeha Lebelo: 80-120 SFM
• Sekhahla sa ho fepa: 0.8-1.2 mm / leino
• Coolant: 8% emulsion ea maiketsetso
  Sena se thibela ho thatafala ha mosebetsi ha o ntse o fihlella Ra<1.6μm holim'a liphetho tse hlokahalang bakeng sa likarolo tsa sefofane.

Ho khetha Letlapa le nepahetseng la HSS: Lintlha tsa bohlokoa

Lintlha tsa Geometry ea Leino

• Hook Angles: +10 ° ho +20 ° bakeng sa tšepe e bonolo; -5 ° bakeng sa lisebelisoa tse brittle
• Boima ba meno: 60-80 TPI bakeng sa li-tubing tse tšesaane tsa lerako; 8-14 TPI bakeng sa stock e tiileng
• Moralo oa Gullet: Li-profiles tse tebileng tsa curvilinear bakeng sa phallo e sebetsang ea chip

Litaelo tsa Ntlafatso ea Ts'ebetso
E ipapisitse le tlhahlobo ea moralo oa liteko oa likarolo tsa mochini oa 1:

1. Beha taolo ea lebelo la ho itšeha pele (Vc) bakeng sa bophelo ba sesebelisoa - 20% ho feta lebelo ho baka 56% ho potlakisa ho roala
2. Fetola sekhahla sa phepelo (F) bakeng sa pheletso ea bokaholimo - keketseho ea 30% e phahamisa Ra ka 14% boholo
3. Ho leka-lekana botebo ba sehiloeng (Dp) le chip load - le ka mohla u se ke ua feta bophara ba lehare × 1.2

Ho Hlōleha Thibelo Maqheka

• Lekola ho thothomela ha harmonic ho bonts'a tšenyo ea leino
• Lekola li-micro-chipping ho 50% ea bophelo ba lisebelisoa
• Sebelisa mabone a strobe ho netefatsa hore na chip e sebetsa joang
