Grinder for izinkuni: kanjani ukukhetha idivayisi?

Ukugayela kuyinkqubo eyinkimbinkimbi futhi enesizotha. Ngokuvamile kuyadingeka ukucubungula indawo enkulu, futhi kunzima kakhulu ukubhekana nomsebenzi onjalo ngethuluzi lensimbi. Yingakho umshini wokuhlenga izinkuni wadalwa. Leli thuluzi lingabhebhezela phezulu, lisuse i-burrs, lenze ngisho, lisuse upende kanye ne-varnish, njll. Ngokuvamile, le nto iyinkimbinkimbi futhi ekuphileni kwansuku zonke, akungabazeki, kuyasiza.

Okuthi Wonke Umuntu Kufanele Akwazi

Namuhla, akekho osebenza ebhodini lezinkuni ne-emery. Lena indlela engakapheli yisikhathi, okuyinto, nakuba iphumelelayo, inganiki umphumela omuhle. Kumele kucatshangwe ukuthi ngonyaka ngamunye ukumbozwa kokuqeda kube yilapho kukhishwa kancane, kanti nanoma yikuphi ukukhwabanisa emapulini kuzobonakala ngokucacile. Yiqiniso, umshini wokuhlenga izinkuni ukusetshenziswa ekhaya akuyona eyabiza kakhulu, kodwa sizokhuluma ngalokhu okuncane kancane. Kungenye indaba uma usebenza emkhakheni wokukhiqiza, lapho kufanele uhlaziye amabhetshi ezinkuni nsuku zonke. Lapha okukhethwa kukho kuyabonakala - ithuluzi kufanele libe lochwepheshe. Kodwa ngokuvamile, ungaxoxa ngezindleko ezincane, nakuba kuncike kakhulu kumenzi.

Ake sizame ukuqonda nawe ukuthi yisiphi umshini wesicathulo okufanele ukhethe nokuthi yini ongayibona uma uthenga. Lapha, akuzona zonke izinto ezinzima njengoba kungase kubonakale ekuqaleni.

Abaguni abaqeqeshiwe

Izinyathelo zalolu hlobo zikhiqizwa izinkampani eziningi ezaziwayo ezisebenzayo ekukhiqizeni nasekuthengiseni amathuluzi wokwakhiwa namakhaya. Izici eziyinhloko zemishini enjalo, njengombuso, yizona izindlela zokusebenza. Ngokuvamile ama-grinders asetshenziselwe ukuhlinzwa okungapheli isikhathi eside. Ubukhulu bemishini bukhulu kakhulu kunamamodeli angewona ochwepheshe, okubangelwa amandla okwandisa injini.

Ngokuqondene nekhwalithi yokwakha, iphinde ibe sezingeni eliphezulu. Yiqiniso, noma iyiphi imodeli yasendlini nayo kufanele ibe yithembekile. Inamba enkulu yezinhlelo zokusebenza, ikhono lokulungisa isici sokusebenza (ijubane lokujikeleza kwalo) nokunye okuningi - konke lokhu kusezinhlobonhlobo zobuchwepheshe. Ngokuqondene nentengo, i-grinder yezinkuni zalolu hlobo ibiza kakhulu.

Abagaya izindlu

Ithuluzi elinjalo alenzelwe umsebenzi unomphela. Injini yomshini ngeke imelane nokusebenza okude nokungenazinkinga. Ngokwesilinganiso, imithombo yomsebenzi ngenyanga kufanele ibe ngaphezu kwamahora angu-20-30. Ngesikhathi esifanayo amandla eyunithi ayincane, ngakho-ke, kulula kakhulu ukusebenza ngethuluzi elinjalo, elibangelwa ubukhulu obuncane.

Kunconywa ukunikeza ukuphumula emshinini we-sanding njalo ngemizuzu engu-15 yomsebenzi. Ngakho-ke ungakwazi ukunciphisa kakhulu imiphumela eyingozi yokushisa injini futhi ugweme ukulayisha ngokweqile. Ngokuqondene nezinzuzo zezixazululo ezinjalo, i-compact, ilula futhi ilula ukusebenza. Yiqiniso, lapha awunakwenzeka ukuthola inombolo enkulu yemisebenzi eyengeziwe, kodwa akudingeki ukwenza umsebenzi olula. Awu, manje, ngokuningiliziwe mayelana nokuthi ungakhetha kanjani umshini we-sanding ngenkuni, futhi yikuphi ukuhluka kwaleli thuluzi.

Izinhlobo zezigaya zasendlini

Okwamanje, abakhiqizi bazama ukuza nazo zonke izinhlobo ezintsha zamathuluzi anjalo. Izici zokuklama ngokuvamile zihlanganisa izakhi ezihlukene zethuluzi zokusebenza, izakhi zokuklama, njll.

Okuthandwa kakhulu namuhla yimishini yokugaya amabhande (LSM). Zisetshenziselwa ukucubungula okunamandla kwamapulangwe, amaplastiki nezensimbi. Uma udinga i-softer, ngokuvamile ukwelashwa okwesibili, ngakho-ke kunconywa ukuthi usebenzise ukugaya kwe-vibration (GSOM). Ubuningi bomngcele wokugaya kwenza kube lula ukucubungula izingcezu zezingcweti zomsebenzi bese kunciphisa amandla omsebenzi.

Olunye uhlobo ngumshini we-delta sanding. Isici saso esiyinhloko yisimo se-triangular sodwa. Lokhu kuvumela ukugaya izingxenye ezinzima zokufinyelela emsebenzini (ama-notches, grooves, njll).

Yebo, uhlobo lokugcina luyimoto ehamba phambili. Isetshenziselwa ukugaya kokugcina. Ngokujwayelekile emva kokucubungula lokho okungenalutho kubonakala sengathi kuphucuziwe. Lokhu kutholakala ngokunyakaza okujikelezayo-okuvusa amadlingozi ngesikhathi sokusebenza. Ithuluzi elinjalo alungelanga indawo encane ene-complex configuration.

Umshini wokugaya amabhande kanye nakho konke okukuwo

Ithuluzi lebhande livele kuqala. Yenzelwe ukukhwabanisa, ukucubungula okuyisisekelo. Ngokuvamile lisetshenziswe uma udinga ukususa ungqimba olubalulekile lwezinto, uthi, kusukela ebhodini elihleliwe. Kodwa ngaphezu kwalokho, i-LSM ifaneleka ekufakweni ngokuqondile kwezingxenye kanye nokusika imigqa.

Ingxenye yokusebenza iqukethe ibhande elingenalutho, elibhekiswe kuma rollers ajikelezayo. Kuye ngosayizi wokusanhlamvu we-tape, isendlalelo esithile sezinto sisusiwe. Ngokuvamile, lesi simiso sinjengomsebenzi wezindiza, imizamo kuphela okudingeka isetshenziswe kakhulu, futhi umsebenzi wenziwa ngokushesha.

Uma udinga umshini wokuhlenga ibhande, qaphela ijubane le-tape, ububanzi balo nobude. Ububanzi ngokuqondile ngqo kuthinta indawo yokwelapha. Ngokuvamile, ububanzi bamamodeli womkhaya we-tape abufinyeleli ku-100 mm, futhi bukhawulelwe ku-50-80 mm. Ngezidingo zomkhaya, kuyokwanela ukuba ube namandla we-1, 2 kW. Kule nkinga, ungalindela ijubane le-tape lilingana no-150-500 m / iminithi.

Mayelana ne-tape abrasive nemisebenzi ewusizo

Okumangalisa ukuthi, usadinga ukukwazi futhi ngokukhetha ukhethe i-tape abrasive. Kuthengiswa kukhona izinhlobo ezimbili zazo. Itheyipu eyodwa ine-ungqimba elula ye-aluminium oxide, kanti eyesibili - i-zirconium. Umbono wokuqala ikuvumela ukuba ubambe ngobumnene ubuso, ushiye inombolo encane yokumunyu. I-ribbon ene-alumina abrasive ingcono kakhulu ukucubungula izinkuni zezinkuni. Amateyipu e-Zirconium nawo ahle ngendlela yawo. Ngosizo lwabo ungaba masinyane, kodwa ususe ngokucophelela ungqimba lwezinto ezibonakalayo. Kodwa-ke, kuzodingeka samukele ukuthi leyo mikhwazo izohlala phezulu. Le tape inhle kakhulu ezingxenyeni zensimbi, futhi ibuye ifanele ukuqinisa ithuluzi.

Ngokuqondene nemisebenzi eyengeziwe, kuyadingeka ukuthi kukhona kungenzeka ukulungiswa okushelelekile kwejubane lokujikeleza kwe-tape. Lokhu kuzokuvumela ukuba uvumelane ngokuzenzakalelayo ukuze usebenze ngezinto zokwahlukana okuhlukile.

Kodwa ukuba khona kwemisebenzi eyengeziwe kuthinta izindleko zemishini. Isibonelo, umshini wokugaya "i-Interskol Pshm-115" ngaphandle kwemikhiqizo eyengeziwe izobiza ama-ruble angu-2500 ngamandla enjini ka-0.3 kW. Ithuluzi elifanayo lamandla, kodwa selivele lilungiswa ngokusheleleka kanye neminye imisebenzi, izobiza ama-ruble angu-3000 - 3500.

Umshini wokugaya omsakazo: iseluleko ngokuzikhethela

Abaguni be-orbital banesimiso sokusebenza esifanayo ne-GSM ye-triangular. Kodwa i- trajectory of movements kuleli cala ihlukile futhi ivumela ukugaya okungcono kakhulu. Ukukhiqizwa komshini ongokwakheka kuncane kakhulu kunalokho kwe-GSOM.

Uma unquma ukuthenga ithuluzi elinjalo, kufanele uqonde ukuthi udinga i-disc yemitha eyi-150 mm. Amandla ku-0.2-0.65 kW ukusetshenziswa komndeni kuzoba ngaphezu kokwanele. Kumele kuqashelwe ukuthi i-grinder eccentric inejubane lokudlidliza kuze kube ngu-24,000 ngomzuzu. Yingakho ukulungiswa okubushelelezi kulokhu kuzoba umsebenzi owusizo kakhulu. Uma uhlela ukusebenza endlini, bese ukhetha imishini enezimbobo ezisendlini ukuze ulahle uthuli. Lo msebenzi uzosiza kakhulu.

Mayelana nokukhetha kwe-GSOM

Isimiso sokusebenza sezinsika zesibindi ukukwenza ukunyakaza okungahambisani ne-amplitude engaphezu kuka-5 mm. Ngomunye kukhona iziqeshana ezikhethekile noma i-Velcro evumela ukuthi ulungise ishidi le- sandpaper. Kusukela ku-granularity kwalokhu okugcina, ikhwalithi yokucubungula indawo yokhuni incike. Lapho uthola khona okusanhlamvu, ngokushesha ungathola umphumela oyifunayo. Kodwa kulokhu, umsebenzi uzokwenziwa cishe, ngakho-ke, ukucutshungulwa kwesibili nokusanhlamvu okuncane kuyodingeka.

I-Grinder ye-vibratory "Makita", isibonelo, iyinhloko ephezulu kakhulu futhi ithandwa kakhulu phakathi kokuqeqeshwa nokuzijabulisa. Le nqubo ine-anchoring enokwethenjelwa ye-abrasive kuya yedwa, ebaluleke kakhulu. Uma uzofaka ukugaya okuhle, khona-ke ukuphakama kwe-oscillation kufanele kufinyelele ku-1.5-3 mm, ukucubungula okungama-4-5 mm. Qiniseka ukucabangela lokhu uma uthenga. Cishe noma iyiphi i-grinder "iMakita" ikuvumela ukuba ulungise ukuphakama kwe-vibration ehlukahlukene kusuka ku-1.5 ukuya ku-5 mm.

Ngolunye ulwazi mayelana nokukhetha

Ukuthenga ithuluzi elinjalo kufanele njalo kube ngokucophelela futhi kancane kancane. Isibonelo, lapho uthenga imishini yamaShayina, umuntu akanakulindela impilo yesikhathi eside. Kodwa ngisho nethuluzi elinjalo lingaba yi-qualitative. Noma kunjalo, kungcono ukunikeza okuthandwa kwabakhiqizi baseYurophu. Yingakho, ngaphambi kokuthi ukhethe i-grinder futhi uyithenge, bheka ukuthi iyiphi inkampani engumkhiqizi.

Isibonelo, imikhiqizo yaseJalimane "Bosch" cishe ayinakulinganiswa. Ihlanganisa umhlangano ophezulu wekhwalithi, ukunemba ngesikhathi sokugaya, i-ergonomics enekhono nokuningi. Ngokuvamile, i-grinder ye-Bosch nokho futhi iyabiza kakhulu, kodwa kunalokho iyafaneleka. Njengoba umkhuba ubonisa, kuyisisetshenziswa esivela kulo mkhiqizi onenkinga encane, futhi uma iphakama, ixazululwa ngokushesha.

Ngamafuphi mayelana namazinga

Ngakho-ke saqhubeka nokucaphuna okuthakazelisayo kakhulu. Njengoba kuphawuliwe ekuqaleni kwalesi sihloko, inani lixhomeke kakhulu kumkhiqizi kanye nokusebenza komsebenzi. Amamodeli womndeni ngokuvamile abiza phakathi kuka-2000 no-5000 ruble. Eyokuqala isebenzayo elula futhi engaphansi, isebenzayo ivumela ukusebenza okuyinkimbinkimbi ngokunemba okuphakeme. Kuncike kakhulu ukuthi ubani owakhiqiza umshini we-sanding. Intengo yemishini ye-Bosch iphakeme ngo-15-20% kune-Interskol. Kodwa kufanele ukhokhe izinga, kufanele liqondwe.

Isiphetho

Sazi ukuthi singakhetha kanjani umshini wokuwasha izihlahla. Esigabeni sokuqala, sinquma uhlobo lwayo. Khona-ke kubalulekile ukunikeza okuthandayo kulokhu noma lowo mkhiqizi. Ngendlela, kuyoba usizo ukufunda izibuyekezo kumaforamu amahle, ukuze uthole ulwazi oluthe xaxa oluwusizo. Isibonelo, ukulungiswa kwe-grinder evela kwabanye abakhiqizi kungaba nzima ngenxa yokuntuleka kwezingxenye ezithintekayo, okungekho okuhle kakhulu. Ngemuva kokuthi unqume kumkhiqizi nohlobo lomshini, kanye nezici zalo zobuchwepheshe, khetha okukhethwa kukho okungcono kakhulu ngentengo.
