Zvinodiwa zveCNC muchina maturusi pane zvishandiso zvekushandisa
High kuoma uye kupfeka kuramba
Kuoma kwechikamu chekucheka chechishandiso kunofanira kunge kwakakwirira kudarika kuoma kwezvinhu zvekushanda. Iyo yakakwirira kuoma kwezvinhu zvekushandisa, zviri nani kupfeka kwayo kuramba. Kuoma kwezvinhu zvekushandisa pakupisa kwekamuri kunofanira kunge kuri pamusoro peHRC62. Kuoma kwacho kunogona kuva kwakakwirira kudarika kwezvakajairwaCNC machining zvikamu.
Simba rakakwana uye kuoma
Chishandiso chinotakura kudzvinyirirwa kukuru mukuita kwekucheka zvakanyanya. Dzimwe nguva, inoshanda pasi pekubata uye vibration mamiriro. Kudzivirira chishandiso kubva pakutyoka nekutyoka, mudziyo unofanirwa kuve nesimba rakakwana uye kuoma. Kazhinji, simba rekukotama rinoshandiswa kumiririra kusimba kwechishandiso, uye kukosha kwemhedzisiro kunoshandiswa kumiririra kuoma kwechishandiso.
yakakwirira kupisa kusagadzikana
Kudzivirira kupisa kunoreva kuita kwemidziyo yekuchengetedza kuoma, kusakara, simba uye kusimba pasi pekupisa kwakanyanya. Icho chiratidzo chikuru chekuyera kucheka kwekuita kwezvinhu zvekushandisa. Kuita uku kunozivikanwa zvakare sekuomarara kwakatsvuka kwemidziyo yekushandisa.
Good thermal conductivity
Iyo yakakura iyo yekupisa conductivity yemidziyo yekushandisa ndeye, iyo yakanyanya kupisa inotamiswa kubva kune chishandiso, iyo inobatsira kudzikisa tembiricha yekucheka yechishandiso uye kugadzirisa kusimba kwechishandiso.
Good processability
Kuti zvive nyore kugadzirisa uye kugadzira maturusi, zvishandiso zvematurusi zvinodiwa kuti zvive zvakanaka zvekugadzirisa zvinhu, senge forging, rolling, welding, kucheka uye grindability, zvivakwa zvekupisa kupisa uye yakakwirira-tembiricha yepurasitiki deformation yezvigadzirwa zvemidziyo. Kune yakasimwa carbide uye ceramic zvishandiso zvekushandisa, yakanaka sintering uye kumanikidza kuumba zvivakwa zvinodiwa zvakare.
Mhando yemidziyo yekushandisa
high speed simbi
Yakakwira yekumhanya simbi ndeye alloy chishandiso simbi inoumbwa neW, Cr, Mo uye zvimwe zvinhu zvealloy. Iine kugadzikana kwekushisa kwepamusoro, kusimba kwepamusoro uye kuoma, uye imwe dhigirii yekuoma uye kupfeka kusagadzikana, saka yakakodzera kugadzirisa simbi dzisina-ferrous uye zvakasiyana-siyana zvesimbi. Pamusoro pezvo, nekuda kwehunyanzvi hwekugadzira tekinoroji, inokodzera kugadzira maturusi ekugadzira maturusi, kunyanya simbi yeupfu inomhanyisa simbi, ine anisotropic mechanical properties uye inoderedza quenching deformation, Yakakodzera kugadzirwa nemazvo uye yakaoma kugadzira maturusi.
Hard alloy
Cemented carbide ine kuomarara kwakanyanya uye kupfeka kuramba. PakuchekaCNC inoshandura zvikamu, kushanda kwayo kuri nani kupfuura kwesimbi yakakwirira-speed. Kusimba kwayo kwakati wandei kusvika kumakumi enguva iyo yesimbi inomhanya kwazvo, asi kusimba kwayo kwakashata. Nekuda kwekuita kwayo kwakanaka kwekucheka, inoshandiswa zvakanyanya semidziyo yekushandisa.
Kupatsanurwa uye kumaka kwemasimende carbides yekucheka maturusi
Coated blade
1) Iyo yekupfekedza zvinhu zveCVD nzira ndeyeTiC, iyo inowedzera kusimba kwesimende maturusi ecarbide ne1-3 nguva. Coating ukobvu; Kucheka kumucheto kwakagomara; Inobatsira kuvandudza hupenyu hwekumhanya.
2) Zvinhu zvekuputira zvePVD zvemuviri mhute deposition nzira ndeyeTiN, TiAlN uye Ti (C, N), iyo inovandudza kusimba kweiyo simende maturusi ecarbide ne2-10 nguva. Thin coating; Mupendero wakapinza; Zvinobatsira kuderedza simba rekucheka.
★ Ukobvu hwepamusoro hwekuputira ≤ 16um
CBN uye PCD
Cubic boron nitride (CBN) Kuomarara uye kupisa kwekuita kwe cubic boron nitride (CBN) ishoma kune dhaimondi, uye ine yakanyanya kugadzikana yekupisa uye kugadzikana kwakanaka kwemakemikari. Naizvozvo, yakakodzera kugadzira simbi yakaoma, simbi yakaoma, superalloy uye simende carbide.
Polycrystalline diamond (PCD) Kana PCD ichishandiswa semudziyo wekucheka, inosiiwa pane simende ye carbide substrate, uye inogona kupedzisa kupfeka-inodzivirira, kuomarara kwakanyanya kusiri-metallic uye nonferrous alloy zvinhu zvakaita secemented carbide, ceramics, yakakwira silicon aluminium alloy.

kucheka kumhanya
Calculation formula yekucheka kumhanya Vc:
Mune formula:
D - inotenderera dhayamita yeworkpiece kana chishandiso tipi, unit: mm
N - kutenderera kumhanya kwechishandiso kana chishandiso, unit: r/min
Iyo Speed yeMachining Thread ine Ordinary Lathe
Spindle speed n yekutenderedza shinda. Pakucheka shinda, kumhanya kwechirukwa chelathe kunokanganiswa nezvinhu zvakawanda, senge saizi yeshinda yeshinda (kana lead) yebasa rekushanda, kusimudza nekudzikisa hunhu hwemotokari yedhiraivha, uye kukurumidza kwekududzirwa kweshinda. Naizvozvo, kune akasiyana CNC masisitimu, pane mimwe misiyano muspindle yekumhanyisa n yekutenderedza shinda. Iyi inotevera ndiyo fomula yekuverenga iyo spindle kumhanya kana uchitenderedza tambo pane general CNC lathes:
Mune formula:
P - shinda yeshinda kana mutobvu weworkpiece shinda, unit: mm.
K - inishuwarenzi coefficient, kazhinji 80.
Kuverengera kudzika kwega kwega kwekudya kwekugadzira shinda
Huwandu hwematurusi ekushandisa nzira
1) Kugadzira kwakashata
Empirical calculation formula ye rough machining feed: f rough=0.5 R
Ipo: R -- chishandiso tip arc radius mm
F —— rough machining tool feed mm
2) Kupedza
Mune fomula: Rt -- kudzika kwecontour µ m
F —— Chiyero chekudya mm/r
r ε —— Radhiyasi yechishandiso tip arc mm
Siyanisa hutsinye uye pedzisa kutendeuka zvinoenderana nehuwandu hwekudya uye chip breaking groove
F ≥ 0.36 rough machining
0.36 ＞ f ≥ 0.17 semi kupedza
F ＜ 0.17 kupedza kugadzira
Haisi iyo zvinhu zveblade asi chip breaking groove inokanganisa kushata uye kupedzisa machining eblade. Kucheka kunopinza kana chamfer iri pasi pe40um.
