Vickers hardness HV (haholo-holo bakeng sa tekanyo ea boima ba bokaholimo)
Sebelisa indenter ea lisekoere tsa daemane e nang le boima bo ka holimo ho 120 kg le angle e ka holimo ea 136° ho hatella bokaholimo ba thepa le ho lekanya bolelele ba diagonal ba indentation. Mokhoa ona o loketse ho lekola boima ba li-workpieces tse kholoanyane le likarolo tse tebileng tsa bokaholimo.
Leeb hardness HL (portable hardness tester)
Mokhoa oa ho thatafala oa Leeb o sebelisoa ho leka ho thatafala ha thepa. Boleng ba boima ba Leeb bo khethoa ka ho lekanya lebelo la ho khutla la 'mele oa tšusumetso ea sensara sa hardness mabapi le lebelo la tšusumetso bohole ba 1mm ho tloha holim'a sebaka sa mosebetsi nakong ea ts'ebetso, ebe o atisa karolelano ena ka 1000.
Melemo:Leeb hardness tester, e ipapisitseng le thuto ea ho thatafala ha Leeb, e fetotse mekhoa ea khale ea ho hlahloba bothata. Boholo bo nyane ba sensor ea hardness, e ts'oanang le pene, e lumella tlhahlobo ea boima ba letsoho ho li-workpieces ka litsela tse fapaneng sebakeng sa tlhahiso. Bokhoni bona bo thata ho li-desktop hardness testers ho bapisa.
Ho na le lisebelisoa tse fapaneng tsa ho etsa machining, ho latela mofuta oa thepa e sebelisoang. Lisebelisoa tse sebelisoang ka ho fetisisa ke tse tšekaletseng ka ho le letšehali, tse ka ho le letona, le tse bohareng, joalokaha ho bontšitsoe setšoantšong se ka tlase, ho itšetlehile ka mofuta oa mookameli ea ntseng a etsoa. Ho phaella moo, lithulusi tsa tungsten carbide tse nang le liaparo tse nang le mocheso o phahameng li ka sebelisoa ho khaola lisebelisoa tsa tšepe kapa tse sa senyeheng.
2. Tlhahlobo ea lisebelisoa
Hlahloba thipa e khaotsoeng ka hloko pele u e sebelisa. Haeba u sebelisa matla a ho seha a high-speed steel (HSS), leotsa thipa ho netefatsa hore e bohale. Haeba u sebelisa thipa e arohaneng ea carbide, hlahloba hore na lehare le boemong bo botle.
3. Ho eketsa boima ba ho kenya thipa ea ho itšeha
Ho tiea ha sesebelisoa ho matlafatsoa ka ho fokotsa bolelele ba sesebelisoa se hlahelletseng ka ntle ho turret. Li-diameter tse kholoanyane kapa li-workpieces tse matla li hloka ho lokisoa ka makhetlo a 'maloa ha sesebelisoa se khaola thepa nakong ea ho arohana.
Ka lebaka le tšoanang, ho arohana ho lula ho etsoa haufi le chuck ka hohle kamoo ho ka khonehang (hangata ho pota 3mm) e le ho eketsa boima ba karolo nakong ea karohano, joalokaha ho bontšitsoe setšoantšong.
4. Lokisa sesebelisoa
Sesebelisoa se tlameha ho tsamaisana hantle le x-axis holim'a lathe. Mekhoa e 'meli e tloaelehileng ea ho finyella sena ke ho sebelisa "setting block block" kapa "dial gauge" joalokaha ho bontšitsoe setšoantšong.
Ho etsa bonnete ba hore thipa ea ho itšeha e na le perpendicular ka pele ho chuck, u ka sebelisa sekoahelo sa gauge se nang le sebaka se tšoanang. Ntlha ea pele, lokolla turret, ebe u hokahanya moeli oa turret le sekala sa gauge, 'me qetellong, tiisa li-screws. Hlokomela hore gauge e se ke ea oa.
Ho etsa bonnete ba hore sesebelisoa ke perpendicular ho chuck, u ka boela sebelisa dial gauge. Hokela mochine oa ho daela holim'a molamu o kopanyang 'me u o behe holim'a terene (u se ke ua thella haufi le terene; e lokise sebakeng). Supa lebitso ho sesebelisoa 'me u se tsamaise haufi le x-axis ha u ntse u sheba liphetoho ho gauge ea ho daela. Phoso ea +/-0.02mm ea amoheleha.
5. Sheba bolelele ba sesebelisoa
Ha u sebelisa lisebelisoa holim'a li-lathes, ho bohlokoa ho hlahloba le ho lokisa bophahamo ba thipa e arohaneng e le hore e be haufi le setsi sa mokokotlo ka hohle kamoo ho ka khonehang. Haeba sesebelisoa sa karohano se le sieo setsing se otlolohileng, se ke ke sa khaola hantle 'me se ka senyeha nakong ea machining.
Joalo ka lithipa tse ling, lithipa tse arohaneng li tlameha ho sebelisa boemo ba lathe kapa rula e le hore ntlha e be bohareng ba e otlolohileng.
6. Eketsa oli ea ho itšeha
Ha u sebelisa koloi e tloaelehileng, u se ke ua sebelisa ho fepa ka mokhoa o itekanetseng, 'me u be le bonnete ba hore u sebelisa oli e ngata ea ho itšeha, hobane mokhoa oa ho itšeha o hlahisa mocheso o mongata. Kahoo, ho chesa haholo ka mor'a ho khaola. Tšela oli e ngata e sehang ntlheng ea thipa e sehang.
7. Lebelo la bokaholimo
Ha o khaola koloi e akaretsang, motho ea sehang hangata o lokela ho khaoloa ka 60% ea lebelo le fumanoang bukeng.
Mohlala:Mokhoa o nepahetseng oa ho sebetsae nang le seha carbide lekanya lebelo la 25.4mm bophara aluminium le 25.4mm bophara tšepe e bonolo workpiece.
Ntlha ea pele, sheba lebelo le khothalletsoang, High Speed Steel (HSS) Parting Cutter (V-Aluminium ≈ 250 ft / min, V-Steel ≈ 100 ft / min).
E latelang, bala:
N Aluminium [rpm] = 12 × V / (π × D)
=12 ho/maft × 250 ft/min / (π × 1 ho/rpm)
≈ Liphetoho tse 950 ka motsotso
N tšepe [rpm] = 12 × V / (π × D)
=12 ho/maft × 100 ft/min / (π × 1 ho/rpm)
≈ Liphetoho tse 380 ka motsotso
Tlhokomeliso: N aluminium ≈ 570 rpm le N tšepe ≈ 230 rpm ka lebaka la tlatsetso ea buka ea oli ea seha, e fokotsang lebelo ho 60%. Ka kopo hlokomela hore tsena ke li-maximus mme ts'ireletso e tlameha ho nahanoa; Ka hona, lisebelisoa tse nyane, ho sa tsotelehe liphetho tsa lipalo, li ke ke tsa feta 600RPM.
