Zvigayomaturusi ane mashandiro akawanda anoshandiswa kuona, kuchera, kudonhedza, kudonhedza uye kwakasiyana siyana kwekugaya.
Tapered end millsdzakagadzirwa nekucheka kumucheto kunotepa kumagumo.Iwo anoshandiswa mune akati wandei kufa uye mold application.
Mhando dzenyere:
Nyere dzine mikoto kana mipata yakachekwa mukati memuviri wechishandiso.Nhamba yepamusoro yenyere inowedzera simba rechishandiso uye inoderedza nzvimbo kana chip kuyerera.Zvigayo zvekupedzisira zvine nyere shoma pamucheto wekucheka zvichava nepamusoro chip nzvimbo, nepo magumo ekupedzisira ane nyere dzakawanda achakwanisa kushandiswa pane zvakaoma kucheka zvinhu.
Nyere Imwemadhizaini anoshandiswa kumhanyisa-kumhanya machining uye yakakwirira-vhoriyamu yekubvisa zvinhu.
Nyere ina/Multiple nyeremadhizaini anobvumira kukurumidza kudya mitengo, asi nekuda kwekuderedzwa kwenyere nzvimbo, kubviswa kwechip kungave dambudziko.Ivo vanogadzira yakanakisa kupedzisa kupfuura maviri nematatu enyere maturusi.Yakanakira peripheral uye kupedza milling.
Nyere mbirimadhizaini ane huwandu hwakawanda hwenzvimbo yenyere.Ivo vanobvumira kuwanda kwekutakura chip uye anoshandiswa zvakanyanya mukutsveta uye kuisa muhomwe zvinhu zvisina ferrous.
Nyere nhatumadhizaini ane nzvimbo imwechete yenyere senyere mbiri, asi zvakare iine yakakura muchinjiko-chikamu chekusimba kukuru.Iwo anoshandiswa kuisa muhomwe uye slotting ferrous uye nonferrous zvinhu.
Cutting Tool Materials:
High Speed Steel (HSS)inopa kumira kwakanaka uye inodhura zvishoma pane cobalt kana carbide end mill.HSS inoshandiswa kugaya-chinangwa kugaya zvese zviri zviviri ferrous uye nonferrous zvinhu.
Vanadium High Speed Steel (HSSE)inogadzirwa nesimbi yekumhanyisa, kabhoni, vanadium carbide uye mamwe maalloys akagadzirirwa kuwedzera abrasive kupfeka kuramba uye kuoma.Inowanzo shandiswa kune zvakajairwa kunyorera pane simbi isina tsvina uye yakakwira silicon aluminum.
Cobalt (M-42: 8% Cobalt):Inopa zvirinani kupfeka kuramba, kuomarara kwepamusoro uye kuoma kupfuura kumhanyisa simbi (HSS).Iko kune kushoma kupfava kana microchipping pasi peyakaomarara mamiriro ekucheka, ichibvumira chishandiso kumhanya 10% nekukurumidza kupfuura HSS, zvichikonzera yakanakisa simbi yekubvisa mitengo uye yakanaka kupera.Icho chinhu chinodhura-chinoshanda chakanakira machining cast iron, simbi uye titanium alloys.
Powdered Metal (PM)yakasimba uye inodhura zvakanyanya kupfuura yakasimba carbide.Iyo yakaoma uye isinganyanyi kuparuka.PM inoita zvakanaka mumidziyo <30RC uye inoshandiswa mukutyisa kukuru uye yakakwirira-stock application senge roughing.
Solid Carbideinopa kusimba kuri nani pane simbi inomhanya-mhanya (HSS).Iyo inodzivirira kupisa zvakanyanya uye inoshandiswa pakumhanyisa kunyorera pasimbi yakakandwa, nonferrous zvinhu, mapurasitiki uye zvimwe zvakaoma-kune-muchina zvinhu.Carbide end mill inopa kusimba kuri nani uye inogona kumhanya 2-3X nekukurumidza kupfuura HSS.Nekudaro, mareti ekudya anorema anonyanya kukodzera HSS uye cobalt zvishandiso.

Polycrystalline Diamond (PCD)idhaimondi rekugadzira rinotyisa uye rinopfeka rinobvumira kucheka nekumhanya kwakanyanya pazvinhu zvisina ferrous, mapurasitiki, uye alloys yakaoma kwazvo kumuchina.
Standard Coatings/Finishes:
Titanium Nitride (TiN)ndeye-general-chinangwa coating inopa lubricity yakakwira uye inowedzera kuyerera kwechip muzvinhu zvakapfava.Kupisa uye kuomarara kuramba kunobvumira chishandiso kuti chimhanye nekumhanya kwepamusoro kwe25% kusvika 30% mukumhanyisa machining vs. zvishandiso zvisina kuvharwa.
Titanium Carbonitride (TiCN)yakaoma uye inoshingirira kupfeka kupfuura Titanium Nitride (TiN).Inowanzoshandiswa pasimbi isina tsvina, simbi yakakandwa uye aluminium alloys.TiCN inogona kupa kugona kumhanyisa maapplication pakakwirira spindle kumhanya.Chenjerera pazvinhu zvisina ferrous nekuda kwekatsika kekuita nduru.Inoda kuwedzera kwe75-100% mukumhanyisa machining vs. zvishandiso zvisina kuvharwa.
Titanium Aluminium Nitride (TiAlN)ine kuoma kwepamusoro uye tembiricha yeoxidation maringe neTitanium Nitride (TiN) uye Titanium Carbonitride (TiCN).Yakanakira simbi isina tsvina, yakakwira alloy kabhoni simbi, nickel-based high-temperature alloys uye titanium alloys.Shandisa kungwarira muzvinhu zvisina ferrous nekuda kwemaitiro ekuita nduru.Inoda kuwedzera kwe75% kusvika 100% mukumhanyisa machining vs. zvishandiso zvisina kuvharwa.
Aluminium Titanium Nitride (AlTiN)ndeimwe yeabrasive-resistant uye yakaoma machira.Inowanzoshandiswa kugadzira ndege uye zvinhu zvemuchadenga, nickel alloy, simbi isina tsvina, titanium, simbi yakakandwa uye kabhoni simbi.
Zirconium Nitride (ZrN)yakafanana neTitanium Nitride (TiN), asi ine tembiricha yakakwira oxidation uye inoramba kunamatira uye inodzivirira kumucheto kuvaka.Inowanzoshandiswa pazvinhu zvisina ferrous zvinosanganisira aluminium, ndarira, mhangura uye titanium.
Zvishandiso zvisina kuvharwausave nerutsigiro rwekurapa pamucheto wekucheka.Iwo anoshandiswa pakumhanya kwakaderedzwa kweakajairika application pane nonferrous simbi.
