The Cutting Edge: Kamoo Liseha tsa Sejoale-joale tsa ho Hala Patsi li Fetolisang Ts'ebetso ea Lintho

Basehang ba lehong ke lisebelisoa tse khethehileng tsa ho seha tse etselitsoeng ho bopa, ho betla kapa ho tlosa lintho tse entsoeng ka lehong ho sebelisa motsamao o potolohang. Ba ikamahanya le mechini ea ho sila, li-routers, kapa CNC (Computer Numerical Control) sistimi, ba hohela mecheng e bohale le lijeometri tse ikhethang ho etsa mesebetsi e kang ho etsa profiling, grooving, dadoing le contouring. Ho tloha ho li-cutlets tse bonolo tse otlolohileng ho ea ho litšoantšo tse rarahaneng tsa 3D, li-cutters tsena li na le mekhoa e mengata e lekaneng ea ho sebetsana le mefuta e mengata ea lisebelisoa tsa mapolanka.

Likarolo tsa Bohlokoa tsa Li-Wood Milling Cutters

1. Sebopeho sa Lintho

Thepa ea mochini o silang oa lehong o ama ka kotloloho ho tšoarella ha eona, ho nchocho le ts'ebetso ea eona. Lisebelisoa tse tloaelehileng haholo li kenyelletsa:

• High-Speed ​​Steel (HSS): Li-cutlets tsa HSS li fumaneha ka theko e tlaase ebile li sebetsa ka tsela e fapaneng, li loketse mapolanka a bonolo le tšebeliso ea nako le nako. Li boloka bohale ka lebelo le itekanetseng 'me ho bonolo ho li chorisa

• Carbide-Tipped: Li-cutters tsena li na le 'mele oa tšepe o nang le li-carbide tse kentsoeng (tungsten carbide) makhatheng a ho itšeha. Carbide e thata ebile e mamella mocheso ho feta HSS, e etsa hore e be e loketseng bakeng sa mapolanka a thata, plywood, le tlhahiso ea molumo o phahameng. Li nka nako e telele ka makhetlo a 5-10 ho feta HSS

• Solid Carbide: Bakeng sa mosebetsi o nepahetseng le lisebelisoa tse thata haholo (joalo ka lifate tse thata tse sa tloaelehang), li-carbide cutters li fana ka bohale bo ke keng ba hlōloa le ho hanyetsa ho apara, le hoja li le bobebe ebile li bitsa chelete e ngata.

2. Geometry ea Sekhahla

Sebopeho le moralo oa sehahi li khetholla mosebetsi oa sona:

• Straight Cutters: E sebelisetsoa ho etsa libaka tse bataletseng, li-grooves, kapa li-dados. Li na le moeli o otlolohileng 'me li fumaneha ka bophara bo fapaneng

• Li-router Bits: Kenyelletsa lintlha tse kang roundover, chamfer, le ogee, tse etselitsoeng ho bopa likarolo kapa ho etsa lintlha tse khabisitsoeng.

• Li-End Mills: Likarolo tse sehang qetellong le mahlakoreng, tse loketseng ho betla ka 3D, ho betla le ho etsa profiling mecheng ea CNC.

• Spiral Cutters: Potoloha ka mokhoa o pota-potileng, o fokotsa ho taboha le ho hlahisa lithapo tse boreleli—tse loketseng mapolanka a thata le li-veneers.

3. Shank Size

Shank ke karolo e sa seheng e khomarelang mochine. Mefuta e tloaelehileng e kenyelletsa ¼ inch, ½ inch, le ⅜ inch bakeng sa lirutha, ha mechine ea CNC e atisa ho sebelisa lishanka tse kholoanyane (mohlala, 10mm kapa 12mm) bakeng sa botsitso nakong ea ts'ebetso ea lebelo le phahameng. Ho bapisa boholo ba shank le mochini oa hau ho netefatsa hore o lekana hantle mme o fokotsa ho thothomela

Tlhahisoleseding ea Teknoloji: Kamoo Li-Cutters tsa Wood Milling li Etsang kateng

1. Ho Seha Lebelo le Sekhahla sa Lijo

• Lebelo la ho Seha: E lekanngoa ka maoto ka motsotso (FPM), e bolela hore na moeli oa seha o tsamaea ka potlako hakae lehong. Softwoods (mohlala, phaene) e hloka lebelo le tlase (1,000–3,000 FPM), ha lifate tse thata (mohlala, oak) li hloka lebelo le holimo (3,000–6,000 FPM) ho thibela ho chesa.

• Feed Rate: Lebelo leo patsi e feptjoang ka lona ho seha (li-inch ka motsotso, IPM). Sekhahla sa ho fepa butle bakeng sa lisebelisoa tse thata se tiisa ho khaola ho hloekileng, ha litefiso tse potlakileng li sebetsa bakeng sa lifate tse bonolo. Li-cutters tsa Carbide li ka sebetsana le litefiso tse phahameng tsa phepelo ho feta HSS ka lebaka la ho hanyetsa mocheso

2. Palo ea Flutes

Flutes ke li-grooves tse lumellang li-chips ho baleha. Li-cutters tse nang le liphala tse fokolang (2-3) li tlosa lintho tse bonahalang kapele, li etsa hore li be ntle bakeng sa ho hlaba. Liphala tse eketsehileng (4–6) li hlahisa likhalase tse ntle ka ho fokotsa boholo ba chip—tse loketseng bakeng sa ho qaqisa mosebetsi.

3. Helix Angle

Lehlakore la lekolilo le amanang le axis ea cutter le ama ho tsoa ha chip le matla a ho itšeha. Akkele e tlase ea helix (10-20 °) e fana ka torque e eketsehileng bakeng sa lisebelisoa tse thata, ha sekhutlo se phahameng sa helix (30-45 °) se lumella ho itšeha ka potlako le ho phethoa ha bonolo lifateng tse bonolo.

Melemo ea ho sebelisa li-cutters tsa boleng bo holimo tsa Wood Milling

1. Ho Nepaha le ho Nepaha

Li-cutters tsa boleng bo holimo, haholo-holo li-carbide-tipped kapa CNC-specific models, li fana ka mamello e tiileng (ho fihla ho 0.001 inches), li netefatsa hore liphetho tse tsitsitseng tsa ho kopanya, li-inlay le meralo e rarahaneng. Ho nepahala hona ho bohlokoa bakeng sa merero ea profeshenale moo ho hlokahalang le ho phethela

2. Ho tšoarella le ho phela nako e telele

Li-cutters tsa Carbide li hanela ho koaheloa le mocheso, li-cutlets tsa HSS tse sa feleng ka lilemo tse sebelisoang haholo. Sena se fokotsa tlhoko ea ho nkela sebaka khafetsa, ho boloka nako le chelete ha nako e ntse e ea

3. Ho feto-fetoha ha maemo

Ka mefuta e mengata e fapaneng ea libopeho le boholo, lihahi tsa lehong li ikamahanya le mesebetsi e fapaneng: ho tloha ho etsa li-dado tse bonolo bakeng sa lishelefo ho isa ho ho betla lipalesa tse rarahaneng tsa thepa ea ka tlung. Li-spiral and compression cutters li bile li sebetsa ka thepa e bobebe joalo ka MDF le plywood ntle le ho taboha.

4. Katleho

Liseha tsa sejoale-joale, tse kang meralo ea spiral kapa ea multiflute, li fokotsa nako ea ho itšeha ka ho tlosa thepa kapele le ho fokotsa litšila. Li boetse li hloka ho fokotsoa ha lehlabathe kamora moo, ho nolofatsa ts'ebetso ea ts'ebetso

5. Polokeho

Li-cutters tse hlokometsoeng hantle, tse bohale li fokotsa ho thothomela le li-kickback, li etsa hore li bolokehe ho sebelisoa. Ka lehlakoreng le leng, li-dull cutters li ka etsa hore mochini o tlamehe, 'me li eketsa kotsi ea likotsi

Ho Khetha Sekhabi se Nepahetseng sa ho Milling Wood bakeng sa Morero oa Hau

• Boitsebiso: Sebelisa HSS bakeng sa softwoods le ho sebelisoa ka linako tse ling; carbide-tipped bakeng sa hardwoods, plywood, kapa bophahamo ba modumo e phahameng

• Mosebetsi: Li-cutters tse otlolohileng bakeng sa li-grooves, li-router bits bakeng sa metse, li-mill bakeng sa mosebetsi oa 3D.

• Mochini: Bapisa boholo ba shank le router ea hau kapa mochini oa CNC
