Chikamu chekutanga

Chishandiso chishandiso chakakosha mukucheka kugadzira, ingave iri yakajairika muchina chishandiso, kana yepamusoro nhamba yekudzora muchina chishandiso (NC), machining Center (MC) uye inoshanduka yekugadzira system (FMC), inofanirwa kuvimba nechishandiso kupedzisa kucheka. process. Kuvandudzwa kwezvishandiso kune mhedzisiro yakananga pakuvandudza kugadzirwa uye kunaka kwekugadzirisa. Material, chimiro uye geometry ndizvo zvinhu zvitatu zvinotaridza kucheka kwechishandiso, umo kuita kwechishandiso kunoita basa rakakosha.

Sechikamu chakakosha chemidziyo yemidziyo, simende carbide inoita basa risingadzokerike mukucheka kwemazuva ano kugadzira. Cemented carbide kuomarara kwakanyanya, refractory simbi carbide (WC, TiC, nezvimwewo) yeiyo micron order yehukuru hupfu, yakasimwa neCo, Mo, Ni uye zvimwe binder poda metallurgy zvigadzirwa, izvo zvinopisa tembiricha yecarbide inodarika yakakwira. -speed simbi, tembiricha inobvumidzwa yekucheka inosvika 800 ~ 1000 ℃, yakajairika tembiricha kuomarara kweHRC89 ~ 93, 760 ℃ kuomarara kweHRC77 ~ 85, kucheka kukurumidza kusvika 100 ~ 300m/min, zvakanyanya kupfuura simbi yekumhanya, Hupenyu hwakati wandei kusvika makumi enguva dzesimbi inomhanya-mhanya, asi kusimba uye kuomarara kunongova 1/30 ~ 1/8 yesimbi inomhanya-mhanya, kusakwanisa kutsungirira kuvhunduka uye kukanganisa. Iye zvino yave imwe yezvishandiso zvikuru zvekushandisa.

IInternational Organisation for Standardization (ISO) inokamura carbide yekucheka maturusi muzvikamu zvitanhatu:

1. Type P

Inoumbwa neWC, Co uye 5% ~ 30% TiC, inozivikanwawo se tungsten titanium cobalt carbide, giredhi YT5, YT14, YT15, YT30, iyo TiC yemukati i5%, 14%, 15%, 30%, inoenderana. Co content ndeye 10%, 8%, 6%, 4%, kuoma HRA91.5 ~ 92.5. Tiye anokotama simba i900 ~ 1400MPa. TiC yemukati yakawedzera, Co zvemukati zvakadzikira, kuoma uye kupfeka kuramba kwakawedzera, asi kuoma kwesimba kwakadzikira zvakanyanya. Rudzi urwu rwealloy rune kuomarara kwakanyanya uye kupfeka kuramba, kunaka kunamatira uye kupararira kuramba uye oxidation kuramba. Asi simba rekukotama, kuita kwekukuya uye kupisa kwekushisa kuderera, kuderera kwekushisa kwekushisa, kuoma kwakashata. Inokodzera high speed cutting steel material. Iyo yakakwira iyo Co yemukati yealloy, zviri nani kukotama simba uye kukanganisa kuoma, kwakakodzera roughing. Iyo Co yemukati yakaderedzwa, iyo kuoma, kupfeka kusagadzikana uye kupisa kupisa kunowedzerwa, uye kwakakodzera kupedzisa. Kubatana pakati peTi element mune alloy uye iyo Ti chinhu muneworkpieceichagadzira yakakomba yekunamira chishandiso chiitiko, icho chinozowedzera kupfeka kwechishandiso kana yakakwira tembiricha yekucheka uye yakakura friction factor, uye haina kukodzera kugadzirisa simbi isina tsvina uye titanium alloy.

2. Type K

Yakaumbwa neWC uye Co, inozivikanwawo se tungsten cobalt tungsten carbide, inowanzoshandiswa mamakisi YG6, YG8, YG3X, YG6X, ine Co ye6%, 8%, 3%, 6%. Kuoma HRA89 ~ 91.5, kukotama simba 1100 ~ 1500GPa. Chimiro chakakamurwa kuita zviyo zvakakora, zviyo zvepakati uye zviyo zvakanaka. Kazhinji (senge YG6, YG8) yechimiro chezviyo zvepakati, yakanaka zviyo carbide (yakadai seYG3X, YG6X) ine huwandu hwakafanana hweCo pane kuoma kwezviyo zvepakati,zvayokupfeka kuramba kwakakwira zvishoma, kukotama simba uyekuomavarikuderera zvishoma. Iri rudzi rwe alloy kuoma, kukuya, kupisa conductivity yakanaka, yakakodzera kugadzirisa brittle zvinhu..

3. Type M

Pahwaro hweWC, TiC uye Co, TaC (kana NbC) inowedzerwa kune kuumbwa, kuwedzera TaC (NbC) kuYT inogona kuvandudza simba rayo rekukotama, simba rekuneta, kusimba kwekuita, kuoma kwekushisa kwakanyanya, simba uye oxidation kuramba, kupfeka. kuramba zvichingodaro. Anowanzo shandiswa mamakisi YW1 uye YW2. Inogona kushandiswa kugadzira simbi yakakandwa, isina-ferrous simbi uye simbi, asi zvakare inogona kugadzira yakakwira-tembiricha alloy, simbi isina tsvina uye zvimwe zvakaoma.-to-process zvinhu.

4. Type H

Inonyanya kushandiswa kucheka zvinhu zvakakwirira zvakaoma, zvakadai sesimbi yakaoma, chilled cast iron nezvimwe zvakadaro. Cubic boron nitride PCBN yakanyorwa muKirasi H.

5.Type S

Inoshandiswa kucheka zvinhu zvinodzivirira kupisa,super-alloys, nezvimwewo.

6.Type H

Inoshandiswa kucheka simbi dzisina ferrous. Polycrystalline diamond PCD inosanganisirwa mukirasi N.

Muchinyorwa chino, ndakataura marudzi matanhatu ecemented carbide nekuisa kupatsanura maturusi ekucheka, chikamu chinotevera, pachave nemamwe marudzi matsva ecemented carbide kupedzisa, ndapota don.’t kukanganwa kutarisa hafu inotevera kana iwe uchida.

ZZBETTER inogadzira zvigadzirwa zveTC/WC zvine makore anopfuura gumi ruzivo, taura nesu kana uine chero chaunoda nezve tungsten carbide zvinhu kana zvigadzirwa zvakaomarara. Mirira kubvunza kwako, isu takavimbika zvechokwadi.
