Nzira dzekurapa dzepamusoro dzeCNC dzakagadzirwa zvikamu

Muindasitiri yekugadzira prototyping yekukurumidza, kwakasiyana siyana kurapwa kwepamusoro kunoshandiswa. Kurapa kwepamusoro (Surface treatment) kunoreva kuumbwa kwechitubu chine chinhu chimwe chete kana kupfuura pamusoro pechinhu nenzira dzemuviri kana dzemakemikari. Kurapa kwepamusoro kunogona kuvandudza chitarisiko, kupfeka kuramba, corrosion kuramba, kuoma, simba uye mamwe maitiro echigadzirwa.

1. Default machined pamusoro

Nzvimbo dzakagadzirwa nemuchina dzinowanzo kurapa pamusoro. Iyo yepamusoro yechikamu chakaumbwa mushure meCNC machining yapedzwa ichava nemitsara yakajeka yekugadzirisa, uye iyo yepamusoro roughness kukosha ndeye Ra0.2-Ra3.2. Iko kunowanzove nepamusoro pekurapa senge deburring uye inopinza edge kubviswa. Iyi yepamusoro inokodzera zvinhu zvose.

2. Kuputika kwejecha

Iyo nzira yekuchenesa uye roughening pamusoro peiyo substrate uchishandisa iyo yekumhanyisa-kumhanya kwejecha kuyerera inobvumira pamusoro peiyo workpiece kuwana imwe dhigirii yehutsanana uye kwakasiyana roughness, nekudaro inovandudza ma mechanics epamusoro peiyo workpiece, nekudaro inovandudza kusimba kwekuneta kweiyo workpiece uye kuwedzera iyo Kunamatira pakati payo nekuputira kunowedzera kusimba kweiyo firimu uye kushongedza kunowedzera kusimba kweiyo coating uye kushongedza kunobatsirawo.

2. Kukwenenzvera

Iyo electrochemical process inochenesa zvinhu zvesimbi nekuita iyo simbi inopenya kuderedza ngura uye kunatsiridza chitarisiko. Inobvisa inenge 0.0001"-0.0025" yesimbi. Inoenderana neASTM B912-02.

4. Anodizing akajairika

Kuti ukunde hurema mualuminium alloy pamusoro kuoma uye kupfeka kuramba, kuwedzera chiyero chekushandisa, uye kuwedzera hupenyu hwesevhisi, anodizing tekinoroji ndiyo inonyanya kushandiswa uye yakabudirira. Zvakajeka, dema, tsvuku uye goridhe ndiwo mavara akajairika, anowanzobatanidzwa nealuminium. (Cherechedza: Pachave nemusiyano weruvara pakati peruvara chairo mushure meanodization uye ruvara rwuri pamufananidzo.)

5. Zvakaoma anodized

Ukobvu hweoxidation yakaoma yakakora kupfuura yeyakajairika oxidation. Kazhinji, ukobvu hweakajairwa oxide firimu i8-12UM, uye ukobvu hweiyo hard oxide firimu kazhinji 40-70UM. Kuoma: Zvakajairwa oxidation kazhinji HV250--350

Hard oxidation inowanzova HV350--550. Kuwedzera kuvharidzira, kuwedzera kupfeka kusagadzikana, kuwedzera kwekudzivirira kwemarara, nezvimwewo Asi mutengo uchawedzerawo.

6. Pfaya kupenda

A coating inoshandiswa pamusoro pesimbi workpieces kushongedza uye kudzivirira pamusoro simbi. Iyo inonyanya kukodzera kusimbi-dense zvinhu zvakadai sealuminium, alloys, uye simbi isina tsvina. Inoshandiswa zvakanyanya se electroplating varnish pamiviri yemagetsi emidziyo yemagetsi yakadai semarambi, midziyo yemumba, nzvimbo dzesimbi, uye hunyanzvi hwesimbi. Inogona zvakare kushandiswa seyekudzivirira yekushongedza pendi yemotokari, midhudhudhu accessories, matangi emafuta, nezvimwe.

7.Matte

Shandisa yakanaka abrasive jecha particles kukwiza pamusoro pechigadzirwa kuti ubudise diffuse reflection uye non-linear texture madhara. Mbeu dzakasiyana-siyana dzinoputika dzakanamirwa kuseri kwebepa kana kadhibhodhi, uye hukuru hwezviyo hwakasiyana hunogona kusiyaniswa maererano nekukura kwahwo: hukuru hwezviyo, hukuru hwezviyo zvinoputika, uye zviri nani kushanda kwepamusoro.

8.Pasivation

Nzira yekushandura simbi kuti ive mamiriro asinganyanyi kubatwa neoxidation uye kunonotsa kukora kwesimbi.

9.Galvanized

Galvanized zinc coating pasimbi kana iron kudzivirira ngura. Iyo inonyanya kushandiswa nzira inopisa - dip galvanized, kunyudza zvikamu mukati mekunyunguduka inopisa zinc groove.
