1. Thetapquality haina kunaka
Main zvinhu, CNC chishandiso dhizaini, kupisa kupisa, machining kurongeka, coating quality, etc. Semuenzaniso, mutsauko wesaizi pakuchinja kwepombi muchinjiko-chikamu wakakurisa kana shanduko fillet haina kugadzirwa kuti ikonzere kunetseka, uye iyo. zviri nyore kutyora pakushushikana kwekushushikana panguva yekushandiswa.Iko kuchinjika-chikamu chekuchinjika panosangana shank uye blade iri padhuze zvakanyanya kune weld, zvichikonzera kukwirisa kwekunetsekana kwekusimbisa welding uye kushushikana kwekushushikana kweiyo cross-section shanduko, zvichikonzera kushushikana kukuru, izvo zvinokonzeresa. tap kuti utyoke panguva yekushandisa.Semuenzaniso, nzira isina kunaka yekurapa kupisa.Kana iyo pombi ichipisa kupisa, kana isina preheated isati yadzima uye kudziyisa, kudzima kunopisa kana kupisa-kupisa, kusingadzivirirwe nenguva uye kucheneswa nekukurumidza, zvinogona kukonzera kutsemuka kwepombi.Kusvika pamwero mukuru, ichi zvakare chikonzero chakakosha nei kuita kwese kwemapombi epamba kusiri kwakanaka sekuya kwematepi anotengeswa kunze kwenyika.
Countermeasures: Sarudza mhando dzemhando yepamusoro uye dzakavimbika dzepombi uye mamwe akakodzera tap akatevedzana.
2. Kusarudzwa kusina kunaka kwetaps
Kuteya zvikamu zvine kuoma kwakawandisa, matepi emhando yepamusoro anofanirwa kushandiswa, senge cobalt-ine.high-speed simbi matepi, carbide taps, coated taps, etc. Mukuwedzera, zvakasiyana-siyana zvigadziridzo zvepombi zvinoshandiswa mumamiriro akasiyana ekushanda.Semuenzaniso, nhamba, saizi, kona, nezvimwe zve chip nyere misoro yepombi ine chekuita pakubvisa chip kuita.
Kune zvakaoma-ku-muchina zvinhu zvakadai sekunaya kwesimbi isina tsvina uye yakakwirira-tembiricha alloys ane kuoma kwepamusoro uye kusimba kwakanaka, pombi inogona kutsemuka nekuda kwekusakwana kwayo kwesimba uye haigone kuramba kucheka kwekucheka kwekutapa kugadzirisa.
Mukuwedzera, dambudziko rekusawirirana pakati pepombi uye zvinhu zvekugadzirisa zvakabhadharwa zvakanyanya uye zvakanyanya kutariswa mumakore achangopfuura.Kare, vagadziri vepamba vaigara vachifunga kuti zvigadzirwa zvekunze zviri nani uye zvinodhura, asi zvaive zvakakodzera.Nekuenderera mberi kwekuwedzera kwezvinhu zvitsva uye kugadzirisa kwakaoma, kuitira kuzadzisa ichi chinodiwa, zvakasiyana-siyana zvekushandisa zvekushandisa zviri kuwedzera zvakare.Izvi zvinoda kusarudza yakakodzera pombi chigadzirwa usati wabaya.
Countermeasures: Shandisai matepi emhando yepamusoro-yakasimba (yakadai sehupfu hwepamusoro-tembiricha simbi, nezvimwewo) kuvandudza kusimba kwepombi pachayo;panguva imwe chete, kunatsiridza kupfeka kwepamusoro kwepombi kuti uvandudze kuoma kwepamusoro kwetambo;muzviitiko zvakanyanyisa, kunyangwe kubata nemaoko kungave nzira inogoneka.
3. Kunyanya kupfeka kwetap
Mushure mekunge pombi yagadziriswa maburi akawanda ane shinda, kuramba kwekucheka kunowedzera nekuda kwekunyanya kupera kwepombi, zvichiita kuti pombi iparadzwe.
Countermeasures: Kushandiswa kwepamusoro-soro kupfava mafuta ekuzora kunogonawo kunonoka kunonoka kupera kwepombi;uyezve, kushandiswa kwetambo gauge (T/Z) kunogona kutonga zviri nyore mamiriro epombi.
4. Kuomerwa mukupwanya kwechip uye kubvisa chip
Pakupomba kwegomba remapofu, pombi yekubvisa spiral groove rear chip inowanzoshandiswa.Kana machipisi esimbi akaputirwa papombi uye asingakwanisi kuburitswa zvakanaka, pombi ichavharwa, uye nhamba huru yezvinhu zvakagadziriswa (sesimbi uye simbi isina tsvina uye yakakwirira-tembiricha alloys, nezvimwewo) inobatwa.Machining kazhinji yakaoma kutyora machipisi.
Countermeasures: tanga wafunga kushandura helix angle yepombi (kazhinji kune akawanda akasiyana ehelix angles kusarudza kubva), edza kuita kuti mafirita esimbi abviswe zvakanaka;panguva imwechete, gadzirisa zvigadziro zvekucheka zvakakodzera, chinangwa ndechekuita kuti mapepa esimbi anogona kubviswa zvakanaka;kana zvichidikanwa Variable helix angle taps inogona kusarudzwa kuti ive nechokwadi chekubuda mushe kwesimbi filings.
