Zvinokonzera uye Zviyero zveCemented Carbide Tool Chipping

Cemented carbide tool chipping zvinokonzera uye matanho:

Kupfekwa nekuchekereswa kwezvakaiswa carbide chimwe chezvinhu zvinowanzoitika. Kana carbide inoiswa yakapfekwa, inokanganisa kurongeka kwemuchina, kugona kwekugadzira, mhando yebasa, nezvimwe; Iyo machining process inoongororwa zvakanyatsonaka kuti iwane chikonzero chekuisa kupfeka.

1) Kusarudzika kwakashata kwemagiredhi eblade uye zvakatemwa, senge ukobvu hweblade hwakanyanya kutetepa kana mamakisi akaomesesa uye ane brittle anosarudzwa kune rough machining.

Countermeasures: Wedzera kukora kweblade kana kuisa blade yakatwasuka, uye sarudza giredhi rine yakakwirira kubhenda simba uye kuoma.

2) Kusarudzwa kwakashata kwechishandiso geometric parameters (senge yakakurisa pamberi uye kumashure makona, nezvimwewo).

Countermeasures: Gadzirazve chishandiso kubva pane zvinotevera zvinhu. ① Nyatsoderedza makona ekumberi nekumashure; ② Shandisa yakakura yakaipa mupendero inorerekera; ③ Deredza kona huru yekudzikisa; ④ Shandisa yakakura isina kunaka chamfer kana edge arc; ⑤ Geya shanduko yekucheka kumucheto kuti uwedzere chishandiso tipi.

3) Iyo welding process yeblade haina kururama, zvichikonzera kuwandisa welding kushushikana kana welding kuputika.

Countermeasures: ①Dzivisa kushandisa matatu-mativi akavharwa blade groove chimiro; ②Sarudzo chaiyo ye solder; ③Dzivisa kushandisa oxyacetylene murazvo wekudziya welding, uye gara uchidziya mushure mewelding kubvisa kushushikana kwemukati; ④Shandisa mechanical clamping chimiro zvakanyanya sezvinobvira

4) Nzira yekurodza isina kunaka ichaita kuti kugaya kushushikana uye kugaya kutsemuka; kudengenyeka kwemazino mushure mekurodza PCBN milling cutter yakakura kwazvo, kuitira kuti mazino ega ega awedzere, uye banga richarohwawo.

Countermeasures: 1. Shandisa kukuya kwepakati kana kuti diamond grinding vhiri; 2. Shandisa vhiri rekukuya rakapfava uye richeke kakawanda kuti vhiri rekukuya rirambe rakapinza; 3. Chenjerera kumhando yekurodza uye kunyatso kudzora kuzununguka kwemazino ekugaya anocheka.

5) Kusarudzwa kwehuwandu hwekucheka hahuna musoro. Kana iyo yakawanda yakawandisa, chishandiso chemuchina chinenge chichifinha; kana uchicheka zvishoma nezvishoma, kukurumidza kwekucheka kwakanyanyisa, chiyero chekudya chakakura zvikuru, uye mvumo isina chinhu haisi yunifomu, kudzika kwekucheka kwakanyanya kuduku; kucheka yakakwirira manganese simbi Kune zvinhu zvine hutsika hwepamusoro hwekushanda kuomesa, chiyero chekudya chakanyanya kudiki, nezvimwe.

Countermeasure: Sarudza zvakare huwandu hwekucheka.

6) Zvikonzero zvezvimiro senge isina kuenzana yepasi pepamusoro pebanga groove yechishandiso chakasungirirwa kana blade refu refu inobuda.

Countermeasures: ① Cheka pasi pepasi pegirovha yemidziyo; ② Ronga nzvimbo yekucheka muromo wemvura zvine musoro; ③ Wedzera simende carbide gasket pasi peblade kune yakaomeswa arbor.

7) Kunyanya kupfeka chombo.

Countermeasures: Shandura chishandiso munguva kana kutsiva iyo yekucheka mupendero.

8) Kuyerera kwemvura yekucheka hakuna kukwana kana nzira yekuzadza haina kururama, zvichiita kuti blade inopisa uye inoputika.

Countermeasures: ① Wedzera kuyerera kwemvura yekucheka; ② Ronga nzvimbo yekucheka muromo wemvura zvine musoro; ③ Shandisa nzira dzekutonhodza dzinoshanda senge kupfapfaidza kutonhora kuti uvandudze kutonhora; ④ Shandisa * kucheka kuti uderedze maitiro pane blade.

9) Chishandiso hachina kuisirwa nenzira kwayo, sekuti: mudziyo wekucheka wakaiswa zvakanyanya kana kuderera; iyo face milling cutter inotora asymmetric pasi milling, nezvimwe.

Countermeasure: Isazve chishandiso.

10) Kuomarara kweiyo process system yakashata zvakanyanya, zvichikonzera kuwandisa kwekucheka vibration.

Countermeasures: ① Wedzera tsigiro yekubatsira yeworkpiece kuti uvandudze iyo clamping rigidity yeworkpiece; ② Deredza kureba kwechishandiso; ③ Deredzai zvakakodzera kona yemvumo yechishandiso; ④ Shandisa mamwe matanho ekubvisa kudengenyeka.

11) Kushanda kusina hanya, zvakadai se: kana chimbo chikacheka kubva pakati pebasa rekushanda, chiito chacho chakanyanya chisimba;

Countermeasure: Teerera kune nzira yekushanda.
