1. Tsib Tus Killers Loj Tshaj Plaws Ua Ntej Pom Hniav Ua Tsis Tau
- Kev txias txias tsis txaus.Ib feem tseem ceeb ntawm cov hniav tsis ua tiav ntxov ntxov yog txuas nrog cov teeb meem cua txias. Yog tias cov cua sov tsim tawm thaum txiav tsis raug tshem tawm tam sim ntawd, nws ua rau kom hnav zoo tshaj - thiab qhov phem tshaj, ua rau cov hniav annealing thiab hardness poob. Lub kaum sab xis txias yog qhov tseem ceeb sib npaug: tsom rau ntawm cov hniav gullet es tsis yog cov hniav hau kom zoo npog tag nrho cov cheeb tsam txiav.
- Pub ceev ceev.Pub ceev heev thiab cov hniav yuav overload thiab nti; pub qeeb dhau thiab kev sib txhuam kub ntau dhau yuav ua rau hnav.
- Mismatched Hniav Geometry.Siv cov hniav geometry tsis ncaj ncees lawm exponentially accelerates hnav. Cov hlau sib txawv xav tau cov hniav sib txawv txawv - txhuas hu rau TCG (triple-chip grind) cov hniav, thaum hlau xav tau cov hniav denser.
- Kev khaws cia tsis raug.Cov hniav sib tsoo ua rau cov hniav puas thiab deforms lub cev hniav; Qhov chaw ntub dej ua rau xeb thiab ua rau cov xeb luv luv -kev tiv thaiv kab mob.
- Neglecting Resharpening.Txuas ntxiv siv lub ntsej muag dull yam tsis muaj sijhawm rov ua kom nrawm nrawm rau cov hniav. Ib lub ntsej muag ib txwm tuaj yeem rov kho dua ntau zaus, txhua zaus txuas nws lub neej kev pabcuam.
2. Tsib -Txoj Kev Pom Hniav Kho Hniav
- Kev tshuaj xyuas qhov system txias.Xyuas kom cov dej txias txaus txaus thiab kho lub kaum sab xis (lub hom phiaj ntawm cov hniav gullet, tsis yog qhov ntxeev - 45℃-60℃pom zoo), nrog rau siab ntawm 5-7bar thiab txaus tus nqi ntawm 8-12L / min.
- Pub Parameter Optimization.Xaiv qhov tsim nyog pub ceev raws li cov khoom siv hardness. Nres tam sim rau kev tshuaj xyuas yog tias koj hnov cov suab nrov txawv txav.
- Resharpening tsis tu ncua.Thaum qhov txiav nto ua ntxhib, burrs nce, lossis txiav suab nrov, rov ua dua nrog lub tshuab kev sib tsoo yog xav tau. Txhua resharpening tshem tawm 0.1-0.2mm ntawm lub taub hau tuab - xyuas kom txaus cov tuab tuab ua ntej ua haujlwm.
- Cia kom raug.Khaws cov hniav vertically ntawm racks, tsis txhob stacking thiab ntub ib puag ncig (humidity pom zoo hauv qab 60% RH).
- Kev tshuaj xyuas lub cev tsis tu ncua.Pom hniav lub cev khaws cov kev ntxhov siab sab hauv thaum siv. Tsis tu ncua xyuas cov hniav lub cev flatness thiab runout. Yog tias pom tias deformation lossis kev ntxhov siab ntau dhau lawm, kev kho kev ntxhov siab yuav tsum tau ua los ntawm cov chaw tsim khoom. Hauv kev siv txhua hnub, zam kev txiav ntau dhau thiab kev cuam tshuam loj yuav pab txo qis kev ntxhov siab.
3. Nakamura's Maintenance Recommendations
Nakamura pom zoo kom cov neeg siv khoom tsim "Saw Blade Maintenance Record" rau txhua daim ntawv, sau cov sij hawm txiav, rov suav dua, thiab hnub hloov. Qhov no tsis yog tsuas yog txuas lub neej ntawm cov hniav nkaus xwb tab sis kuj tseem muab cov ntaub ntawv - tsav kev nkag siab rau kev txiav txim siab yuav khoom.
Rau ntau hom hniav, Nakamura muaj cov khoom tshwj xeeb hauv qab no:
- NakamuraCarbide Circular Saw Hniav- Engineered nrog cov cua kub dissipation qhov, tsis yog - nplaum txheej, thiab cua sov- cov lus qhia tiv thaiv carbide kom tswj tau cov chips kom zoo, txwv kev tsim hluav taws xob, thiab txo qis burrs. Zoo tagnrho rau siab - ntim txiav ntawm stainless hlau, txhuas, thiab ntau yam hlau profiles.
- NakamuraCarbide Tipped Saw Hniav- Molybdenum- tsim kom muaj txiaj ntsig zoo tiv thaiv cov hniav chipping, ua rau lawv tsim nyog rau kev txiav tsis tu ncua thiab kev ua haujlwm tsis ruaj khov. Tshwj xeeb zoo - haum rau carbon steel, alloy steel, thiab raj txiav.
- NakamuraArc Ntug 6 TPI Reciprocating Pom Hniav - Bi-kev tsim hlau sib txuas ua ke ntawm qhov siab ntawm - ceev steel txiav ntug nrog lub zog ntawm lub caij nplooj ntoos hlav steel rov qab, nrog 8% cobalt cov ntsiab lus rau kev pab cuam lub neej ntev. Ua rau hnyav demolition thiab xav tau txiav cov hauj lwm, xa siab tshaj plaws yooj thiab txiav fais fab.
4. Kev saib xyuas yog kev nqis peev, tsis yog tus nqi
Ib qho kev kho kom zoo tuaj yeem ua rau lub neej ntev ntawm 30%. Kev saib xyuas kev tshawb fawb niaj hnub tuaj yeem txo cov hniav txhua xyoo los ntawm ntau dua 40%.Nakamura - Cov hniav zoo tsim nyog tau txais kev saib xyuas zoo. Kev saib xyuas zoo ua rau cov hniav zoo.
