Ongororo yeKukundikana Modes muTungsten Carbide Kukuya Wheel Shanks

Iyo carbide kugaya vhiri shank chishandiso chakakosha mukugaya chaiko uye nekumhanyisa machining. Kuita kwayo kunotarisisa zvakanangana nekugadzirisa, kunaka kweworkpiece, uye mutengo wekugadzira. Nekudaro, pasi pemamiriro ekushanda akaomarara, shank inonyanya kutyisidzirwa nematatu ekutadza modes: kupfeka, kucheka, uye kuputsika. Kunzwisisa kwakadzama kwezvinokonzeresa kukundikana uku kwakakosha pakuve nechokwadi chekushanda kwenguva refu uye kwakagadzikana.

1. Kupfeka (Abrasive Wear) - Maitiro Ashoma uye Asingadzivisiki

Kupfeka ndiyo nzira yakajairika uye isingadzivisike yekukundikana. Iyo inonyanya kutaridzika seinononoka uye kunyange kuderedzwa kwehukuru hwechikamu che carbide grinding shaft inobata workpiece.

Zvikonzero Zvikuru: Panguva yekukuya-kumhanya, iyo carbide pamusoro peiyo quill inopinda zvakanyanya kupesana neiyo workpiece zvinhu (kunyanya zvinhu zvakaoma sesimbi yakaoma kana yakakwirira-tembiricha alloys). Izvi zvishoma nezvishoma zvinopedza tunhu tudiki twezvinhu. Kusakwana kana kutadza kutonhorera kunogona kuwedzera kukweshana, kugadzira kupisa, uye kupfeka kweabrasive.

Mhedzisiro: Kupfeka kunotungamira mukudzikira kwehunyanzvi hwekugadzira (semuenzaniso, maburi akakura, maumbirwo akamonyaniswa) uye kupera kwakaipisisa. Masimba ekukuya anowedzerawo zvishoma nezvishoma. Kunyangwe kupfeka kuri kufambira mberi, kuongororwa nguva dzose kunodiwa kudzivirira zvimedu zvebatch zvinokonzerwa nekurasikirwa kwechokwadi.

2. Chipping - Localized Brittle Damage

Kupwanya (Chipping) zvinoreva kuputsika kana kukuvadzwa kudiki-diki kumucheto kana makona e carbide shank. Iyi imhando yekukundikana kwenzvimbo.

Zvikonzero Zvikuru: Impact Mutoro: Kamwe-kamwe kukanganisa masimba anoitika panguva yekushandisa chishandiso (kuputsika), kusangana nenzvimbo dzakaoma mune workpiece, kana panguva isina kuenzana kucheka.

 Clamping Issues: Iyo yakaderera-chaiyo collet, isina kuenzana clamping simba, kana tsvina inogona kuita kuti shank idedere kana kuzununguka zvishoma panguva yekutenderera, ichiisa simba risina kuenzana kumicheto.

Yakaderera Material / Kuomarara: Iyo pachayo inogona kunge ine yakaderera mhedzisiro yekupikisa, kana kukoira kwacho kungave kwakanyanyisa kana kuve nekunyanya kushushikana kwemukati, zvichiita kuti ive nyore kune micro-chipping.

Mhedzisiro: Kucheka nekukasira kunosiya mavanga kana makwara panzvimbo yebasa, zvichiita kuti chirahwe. Kunyangwe kuchekerera kudiki kuchakurumidza kusimudzira iyo inotevera yekupfeka maitiro.

3. Kutsemuka - Njodzi Yakakwana Kukundikana

Kutyoka ndiyo yakanyanya kutadza modhi, inowanzo sanganisira yakakura-yakakura kana yakazara kutyora kwe carbide shank.

Zvikonzero Zvikuru:

Kunyanya Kubhenda Stress:Kushandisa overhang iyo yakarebesa, kana kushandisa chiyero chekudya kana kudzika kwekucheka kwakanyanya, kunogadzira nguva yekukotama inodarika simba re shank.

Resonance & Kuneta:Kutyoka kunogona kuitika kana shank's kutenderera kumhanya ichienderana neayo echisikigo frequency (resonance), ichigadzira hombe chinjana kushushikana. Izvo zvinogona zvakare kukonzeresa nekuneta kutadza kutanga padiki-crack nekuda kwekureba kwenguva yakareba cyclic kurodha.

Internal Defects:Micro-voids kana kusvibiswa mukati meiyo shank zvinhu zvinogona kuita senge yekutanga nzvimbo dzekutyoka.

Kukanganisa Kushanda:Kuputsika kwemuchina kwakanyanya chikonzero chakananga chekutsemuka pakarepo.

Kukanganisa: Kutyoka kune njodzi. Izvo hazvingokonzeresa kurasikirwa kweshank inodhura asi inogona kukuvadza muchina spindle uye inoshanda, zvichitungamira mukurasikirwa kukuru kwehupfumi uye njodzi dzekuchengetedza.

Muchidimbu,aya matatu ekukundikana modes akabatana. Micro-chipping inogona kuve iyo yekutanga nzvimbo yekutsemuka, uye kupfeka zvisina kuenzana kunogona kushandura shank's dynamics, inducing vibration. Kuti udzivise kukundikana zvinobudirira, matanho akarongeka anofanira kutorwa:

Sarudzo yeSainzi:Sarudza iyo chaiyo shank zvinhu, coating, dhayamita, uye overhang zvichibva pane workpiece zvinhu, chokwadi zvinodiwa, uye muchina mamiriro.

Right Clamping:Shandisa ma-collets epamusoro-soro (semuenzaniso, hydraulic collets), iva nechokwadi chokuti akachena, uye asimbise kune torque yakatarwa. Gadzirisa Maitiro Paramita: Kunyatso tevera yakakurudzirwa kumhanya, chiyero chekudya, uye kudzika kwekucheka kuti udzivise kukanganisa mitoro. 

Kuchengetedza Kwakakodzera:Ita shuwa kuti chinotonhodza chinoshanda chapihwa zvakakwana. Gara uchiongorora mamiriro e shank uye shandura shanks dzakasakara kana dzakakuvadzwa nekukurumidza.

Nekunzwisisa idzi nzira dzekutadza uye kuita nzira dzekudzivirira dzakanangwa, unogona kuwedzera zvakanyanya hupenyu hwesevhisi yecarbide grinding wheel quills uye kuve nechokwadi yakagadzikana uye inoshanda machining maitiro.
