Wood Hole Saws: Tshawb nrhiav cov yam ntxwv, Cov Lus Qhia Tshwj Xeeb, thiab qhov zoo ntawm qhov tseem ceeb

Lub qhov rooj ntoo yog ib lub cylindrical txiav cov cuab yeej tsim los tho qhov loj, lub voj voog ntawm cov ntoo thiab cov khoom siv ntoo (xws li plywood, MDF, thiab particleboard). Tsis zoo li kev xyaum, uas tshem tawm cov khoom los ntawm chipping tawm ntawm qhov chaw, qhov saws txiav raws ib puag ncig ntawm lub qhov xav tau, tawm hauv ib lub ntsaws ntawm cov khoom hauv cov saw - qhov no ua rau lawv muaj txiaj ntsig zoo rau kev tsim qhov ntawm ¾ nti mus rau 6 ntiv tes (los yog loj dua) inch. Lawv txuas rau kev xyaum los yog xyaum xovxwm ntawm lub mandrel, lub hauv paus pas nrig uas tuav lub saw thiab xa cov quab yuam sib hloov.

Cov yam ntxwv tseem ceeb ntawm Wood Hole Saws

1. Khoom siv

Cov khoom siv ntawm lub qhov ntoo pom ncaj qha cuam tshuam nws cov kav ntev, txiav ceev, thiab tsim nyog rau kev ua haujlwm sib txawv:

• High-Speed ​​Steel (HSS): Cov khoom siv ntau tshaj plaws rau lub hom phiaj dav dav ntoo qhov saws. HSS yog pheej yig, ntse, thiab ua haujlwm zoo rau cov ntoo mos (xws li ntoo thuv thiab cedar) thiab siv qee zaus. Nws tuaj yeem tuav cov cua sov nruab nrab thiab yooj yim kom ntse thaum npub.

• Bi-Hlau: Cov saws no ua ke nrog kev kub ceev hlau txiav ntug nrog lub cev hloov pauv hlau hlau. HSS cov hniav nyob twj ywm ntev dua, thaum cov hlau alloy tiv thaiv kev khoov lossis tawg - zoo tagnrho rau cov ntoo tawv (xws li ntoo qhib thiab maple) thiab siv ntau zaus. Bi-hlau qhov saws kuj sib xws nrog cov ntaub ntawv xws li yas thiab nyias hlau, ntxiv versatility.

• Carbide-Tipped: Rau cov ntaub ntawv hnyav thiab cov ntoo tawv heev (xws li teak lossis rosewood), carbide-tipped qhov saws muab kev hnav zoo dua. Cov hniav carbide khaws cov sharpness txawm nyob rau hauv high kub, ua rau lawv zoo meej rau cov kws tshaj lij, high-volume tej yaam num.

2. Hniav Tsim

Qhov kev npaj thiab cov duab ntawm cov hniav txiav txim siab npaum li cas huv si thiab ua tau zoo ntawm cov saw txiav:

• Raker Teeth: Ib qho qauv nrog cov hniav sib sib zog nqus thiab ntiav, tsim los tshem cov chips sai. Qhov no txo ​​qis clogging thiab tiv thaiv overheating, ua raker hniav zoo tagnrho rau softwoods thiab cov ntaub ntawv tuab.

• Pilot Drill: Feem ntau lub qhov pom muaj xws li kev xyaum me me ntawm qhov chaw. Qhov kev xyaum ua ntej no tsim ib lub qhov qhia, stabilizing lub saw thiab xyuas kom lub qhov nyob twj ywm hauv nruab nrab-tseem ceeb rau qhov raug, tshwj xeeb tshaj yog nyob rau hauv loj-inch txiav.

• Cov Hniav suav: Ntsuas hauv cov hniav ib nti (TPI), TPI siab dua (18–24) ua kom zoo dua, txiav kom zoo dua (zoo rau cov qhov pom hauv rooj tog), thaum TPI qis (10–14) tshem cov khoom sai dua (zoo dua rau qhov ntxhib, zais qhov).

3. Arbor thiab Mandrel

Lub arbor (los yog mandrel) txuas lub qhov pom rau lub laum. Cov yam ntxwv tseem ceeb muaj xws li:

• Shank Loj: Feem ntau cov mandrels muaj ¼-nti lossis ⅜-inch shank kom haum rau cov qauv xyaum, thaum cov saw loj tuaj yeem siv ½-inch shanks rau kev ruaj ntseg ntxiv hauv cov ntawv thov siab.

• Quick-Release Mechanism: Hwm mandrels suav nrog lub khawm tso tawm sai, tso cai rau cov neeg siv hloov lub qhov pom yam tsis muaj cov cuab yeej-txuag lub sijhawm thaum hloov ntawm qhov ntau thiab tsawg.

Cov Ntaub Ntawv Qhia Txog: Yuav Ua Li Cas Wood Hole Saws Ua

1. Txiav ceev

• RPM (Rotations Ib feeb): Ntoo qhov saws ua tau zoo tshaj plaws ntawm qhov nrawm nrawm. Rau softwoods, 1,500-2,500 RPM yog qhov zoo tagnrho; rau cov ntoo tawv, qeeb rau 500-1,500 RPM kom tsis txhob hlawv ntoo lossis dulling cov hniav.

• Feed Pressure: Siv lub zog, lub teeb siab. Kev quab yuam ntau dhau tuaj yeem ua rau cov saw khi, ua rau lub qhov tsis sib xws lossis kev puas tsuaj rau lub cuab yeej. Cia cov hniav ua haujlwm-cia cov saw pub ib txwm ua kom huv si huv

2. Qhov Ncauj Ntau Yam

Ntoo qhov saws muaj nyob rau hauv txoj kab uas hla ntawm ¾ nti (rau lub qhov txuas me me) txog 12 ntiv tes (rau qhov qhib loj xws li hais lus chaw nres nkoj). Cov txheej txheem tshwj xeeb feem ntau suav nrog ntau qhov ntau thiab tsawg, tso cai rau cov neeg siv los daws ntau yam haujlwm nrog ib qho khoom siv.

3. Qhov tob tob

Qhov ntev ntawm lub saw lub tog raj kheej txiav txim siab qhov tob ntawm qhov nws tuaj yeem txiav. Txheem saws tuav 1-2 ntiv tes, thaum cov qauv txiav sib sib zog nqus (txog 6 ntiv tes) yog tsim los rau cov ntaub ntawv tuab xws li cov kab ntoo lossis cov txee.

Qhov zoo ntawm Kev Siv Zoo Wood Qhov Rooj Saws

1. Efficiency

Lub qhov saws tshem tawm tsuas yog ib puag ncig ntawm lub qhov, tawm hauv lub qhov ntsaws ruaj ruaj ntawm cov ntoo - qhov no siv lub zog tsawg dua qhov drilling tawm tag nrho cheeb tsam, txuag lub sijhawm thiab txo qhov qaug zog. Lawv tau nrawm dua li siv cov khoom siv spade lossis jigsaws rau qhov loj

2. Precision

Nrog rau kev xyaum xyaum thiab ruaj khov tsim, ntoo qhov saws tsim puag ncig, nruab nrab qhov nrog tsawg 偏差 (kev sib txawv). Qhov no yog qhov tseem ceeb rau tej yaam num xws li txhim kho lub qhov rooj xauv, qhov twg misaligned qhov tuaj yeem ua rau qhov haum

3. Ntau yam

Thaum tsim los rau ntoo, qhov zoo saws (tshwj xeeb yog ob-hlau thiab carbide-tipped qauv) tuaj yeem txiav los ntawm lwm cov ntaub ntawv xws li yas, phab ntsa ntub dej, thiab cov hlau nyias. Qhov no ua rau lawv muaj ntau lub hom phiaj hauv kev cob qhia thiab chaw ua haujlwm ..

4. Nqi-zoo

Piv nrog rau cov cuab yeej tshwj xeeb qhov txiav, qhov saws yog pheej yig, tshwj xeeb tshaj yog nyob rau hauv poob lawm. Ib lub teeb tuaj yeem npog ntau qhov diameters, tshem tawm qhov xav tau los yuav cov cuab yeej siv rau txhua qhov loj

5. Txiav txiav

Cov hniav ntse thiab cov nti tshem tawm tau zoo txhais tau tias lub qhov saws tawm ntawm cov npoo du, tsis muaj burr. Qhov no txo ​​cov kev xav tau ntawm cov xuab zeb los yog ua tiav, txuag lub sij hawm hauv kev ua haujlwm - qhov tseem ceeb rau cov haujlwm tshaj lij nrog cov sijhawm teem sijhawm.

Xaiv Txoj Cai Ntoo Qhov Pom Zoo rau Koj Qhov Haujlwm

• Khoom siv: HSS rau softwoods thiab DIY siv; bi-hlau rau hardwoods thiab qee zaus hlau txiav; carbide-tipped rau hnyav-lub luag hauj lwm, kev ua hauj lwm ..

• Qhov Loj: Xaiv lub saw uas phim koj qhov project txoj kab uas hla. Cov khoom siv yog qhov zoo rau kev siv ntau yam, thaum qhov ntau thiab tsawg ua haujlwm rau cov haujlwm tshwj xeeb ..

• Hniav Tsim: Raker hniav rau nti clearance; siab TPI rau kev ua tiav; xyuas kom tus tsav laum yog ntse kom raug.

• Drill Compatibility: Sib phim lub mandrel lub shank loj rau koj lub laum chuck (¼-inch lossis ⅜-inch rau feem ntau hauv tsev xyaum).
