Nyaya: Nei Zvidimbu zveDrill Zvichikundikana | Chinyorwa 14
Mazwi akakosha: drill bit runout, TIR, hole roundness, oversized hole, drill straightness, radial runout, long drill bit deflection, HSS drill bit inspection, chuck runout vs. grinding runout, hole accuracy
Nyaya yekupedzisira munhevedzano iyi yakatarisa zvinodzorwa nekukuya pachikamu chepasi rose — dhayamita yekunze, taper yekumashure, taper yewebhu, uye symmetry yeflute-to-flute. Mutsara mumwe muchinyorwa ichocho wairatidza izvi: kuti dhayamita yekunze nemucheto zvakanaka sei pasi zvinoonekwa zvakananga mu radial runout yechikamu kana changopwanywa. Nyaya ino inotsanangura izvozvo. Runout ndipo panogadziriswa kunyatsocheka kana kusacheka — uye ndicho chinhu chikuru chinoparadzanisa gomba rakatenderera kubva kune rakakura, risingatenderere.
Kupera kwemutambo, mumashoko asina kujeka
Bvisa mazwi acho wobva watanga kubvunza mubvunzo mumwe chete: drill yakatwasuka here? Chidimbu chedrill chine geometric centerline chinomhanya chakarurama ku axis yaro yekutenderera chichatsvaira radius imwechete pese painotenderera. Chidimbu chakakombama zvishoma, kana kuti chakapwanyika pakati pacho, hachidaro - chinozununguka, sezvinoita vhiri risina kuenzana. Kuzununguka ikoko, kwakayerwa nechiratidziro che dial, ndiko kunonzi neindasitiri TIR: total indicated runout.
Zvakakodzera kusiyanisa izvi zvakajeka nekufamba, zvatakakurukura muChinyorwa 8. Kufamba kunoitika panguva iyo chibooreso chinotanga kubata pamusoro - idambudziko rechisel-edge uye lip-symmetry, uye rinomira panguva iyo mipendero inosangana nemadziro egomba. Kuyerera kwakasiyana: kana chikamu chapwanyika uye chatenderera, chinenge chiripo chekucheka kwese, kubva pakubata kwekutanga kusvika pakadzika kwekupedzisira. Kufamba idambudziko rekutanga. Kuyerera kwegomba idambudziko rekucheka kwese, uye ndosaka mhedzisiro yaro ichionekwa zvakasiyana - kwete munzvimbo yegomba, asi muhukuru hwegomba, kutenderera, uye mamiriro emadziro.
Nzvimbo mbiri dzinotanga kurwiswa
Kana mutengi akaona dambudziko rekupera kwemari, chikonzero chacho chingangove chimwe chezvinhu zviviri, uye kusiyanisa zvinhu izvi kunokosha nekuti kugadzirisa kwacho kwakasiyana zvachose.
•Kurutivi rwechidimbu (kugadzira):Kana chidimbu chacho chisina kutwasuka — kubva pakumanikidzwa kwakasara kwakaburitswa mushure mekupisa, kana kubva pakukuyiwa pasina kubatwa pakati pacho chaipo — dhayamita yekunze haina kujeka pakutanga. Hapana kupwanya kwakanyatsogadziriswa kwechikamu chakanga chatove chisina kujeka pachakabva pavhiri rekukuya. Iri idambudziko rekugadzira, uye rinodzorwa padanho rekukuya nekuongorora.
•Rutivi rwekugadzirisa (application):Chirongo chakasakara kana kuti chirongo chakasakara, machipisi kana mafuta zvakavharirwa mushaya, kunamatira zvakanyanya, kana kumhanya kwesimbi muspindle pachayo zvese zvinoita kuti chitenderere kunyangwe pachinhu chakatwasuka zvakakwana. Ichi chimiro chekushandisa, kwete chikanganiso chiri mubooreso.
Nei Zvidimbu Zvirefu Zvichida Kutariswa Kwazvo
Kureba kunowedzera chero kukanganisa kwekutwasuka kuripo. Kutsauka kudiki kwekona kusingayereki pane pfupi kunokonzera kutenderera kukuru pamucheto werefu - chikonzero chimwe chete nei tsvimbo refu ichizununguka zvakanyanya pamucheto wayo kupfuura pfupi kuti ive nekukombama kwakafanana. Ichi ndicho chikonzero nei mabhora marefu achioma kubata akatwasuka pakutanga: pasina rutsigiro rwakakwana panguva yekuita, vanowanzo tora uta hudiki husingazomboonekwi nehupamhi hwakajairwa. Vatengi vanoshanda nemabhora marefu kana kuti mabhora ekureba mundege vane kodzero yekubvunza mutengesi zvakananga kuti runout control yakaita sei pahurefu ihwohwo, pane kufunga kuti inoenderana nechiyero chehurefu hwakajairwa.
Zvinodhura Sei Kurasikirwa Kwemari Mutengi
Nekuti kumhanya kwemvura kunowanikwa kuburikidza nekuchekwa kwese, mhedzisiro yacho inongoitika chete pane kungotsamira pane imwe nhanho:
•Maburi makuru.Dhayamita yedhirowa iri yakakura kupfuura saizi yayo yepakutanga, uye mukaha unowedzera sezvo mvura inoyerera ichiwedzera.
•Maburi asina kutenderera.Chibooreso chisiri kushanda chakarurama hachigone kucheka gomba rakatenderera — iyi haisi mukana, imhedzisiro yakananga yemuchina wekushandisa kunze kwepakati. Kukanganisa kweRoundness kunotevera kumhanya kwechinhu chimwe nechimwe.
•Kusashanda zvakanaka kwemari.Rutivi rwemucheto unotakura mutoro wakawanda runosakara nekukurumidza kupfuura rumwe, uye nekuda kwekuti kusakara kwacho hakuna kuenzana, zviri nyore kupotsa pakutarisa nekukurumidza.
•Madziro emakomba akaomarara.Zviratidzo zvekudzokera shure uye kupera kwakaoma zviratidzo zvinowanzoonekwa, kunyanya kana mvura yakwira.
•Nguva pfupi yekushandisa zvishandiso.Nguva yekushanda kwezvishandiso inoderera zvakanyanya sezvo nguva yekubuda kwezvishandiso ichiwedzera — kuderedzwa kudiki kwekubuda kwezvishandiso kunoita kuti huwandu hwemaburi anogona kucheka huwedzere zvakanyanya usati wada kugayiwazve kana kutsiviwa.
Migumisiro iyi inoenderana zvakananga nechinyorwa chekupedzisira. Kushivirira zvishoma kusvika ku h8 papepa kunogona kupotsa bhendi rekutsungirira mugomba rapera kana kumhanya kusina kudzorwa - izvo zvinonyanya kukosha pakubvumidza kudzokorora, kupindira, uye chero kushanda kwepasi kwakavakirwa pahukuru hwakafanana hwegomba risati rasvika.
Maonero Anoita Vatengi Kuti Dambudziko Racho Rakamira Papi
Chiratidzo che dial chinorwisa chucked bit chinopa TIR zvakananga - mabhora madiki-dhayamita anonyanya kunzwa huwandu hwakatarwa hwekumhanya kupfuura makuru, saka huwandu hunogamuchirwa hunosimba kana dhayamita yadzikira.
Kupfuura kuyerwa, bvunzo yekutsiva inowanzo bvisa chikonzero:
•Chinjana mune imwe drill uye dambudziko rinopera:Dambudziko riripo nechikamu ichocho — kungava kutwasuka kwacho kana kuti chakagayiwa sei.
•Chinjana michina kana kuti chinjanai michina uye dambudziko rinopera:Dambudziko riri pakugadzirisa - mamiriro echuck, spindle runout, kana stickout - kwete drill.
•Hapana kana swap inogadzirisa dambudziko iri:Zvakakodzera kutarisa hurefu hwe stickout, feed parameters, uye workholding rigidity usati wafunga kuti bit kana kuti muchina ndiwo une mhosva.
Izvi zvinoratidza nzira yekuongorora kubva muChinyorwa 8: kuziva kuti chikonzero chiri papi kunoratidza kana danho rinotevera rakakodzera riri rekutaurirana nemutengesi kana kugadzirisa zvinhu muchitoro.
Izvi Zvinorevei Pakuenzanisa Vatengesi
Kushivirirana kwemagetsi nekudzora kumhanya kwemagetsi zvinhu zviviri zvakasiyana, uye zvakakosha kuzvibvunza zvakasiyana. Usati waenzanisa mashoko:
•Kupera kwemvura kunoongororwa here mushure mekukuya, uye chii chakavakirwa pachinhu chekutanga chete, kana kuti kuenderera mberi nekutorwa kwemvura kuburikidza nebatch?
•Pane here mwero wakasiyana wekushandisa mabhora marefu kana kuti marefu, tichifunga kuti kureba kwacho kunowedzera sei kukanganisa kwekutwasuka?
•Mutengesi anogona here kugovana zvinoonekwa neongororo yake — kwete kungoshivirira kunotaurwa papepa reruzivo, asi kuti zvakazosimbiswa papi?
Panyaya yedu, ma "ground bits" anopinda mu "first-piece check" achisimbisa dhayamita yekunze uye "runout" pakutanga kwe "batch" yega yega, zvichiteverwa ne "in-process spot checks" kuburikidza ne "run" - nzira imwechete yakatsanangurwa munyaya yapfuura, inoshandiswa zvakananga pakutwasuka uye "radial runout" kwete dhayamita chete.
Nezvenyaya iyi
Chikonzero nei Drill Bits Isingashande inyaya yehunyanzvi yakanyorwa nechikwata chedu chekugadzira. Chinyorwa chimwe nechimwe chinotarisa pane chimwe chinhu chaicho mukushanda kwedrill bit - kubva pazvinhu zvisina kugadzirwa kusvika pakurongedza. Chinangwa chiri nyore: kubatsira vatengi kunzwisisa zvavari kutenga chaizvo, uye mibvunzo yekubvunza.
