Ho QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., re se re hlophisitse matlo a lisebelisoa tsa tšepe tse fetang 17,000 bakeng sa likopano tsa pompo ea piston ho tloha 2019. Re bone se hlolehang: likere tse nang le maqhutsu a graphite a kopaneng haufi le motso oa leino; likarolo tse tšoaroang ka mocheso ka potlako le ho phunyeha nakong ea ho sila ea ho qetela; li-castings tse tšetsoeng ka likhahla tse sa tsitsang tsa ho pholile tse sothehileng ka mor'a hore CNC contouring. Phihlelo ea sebele—eseng libukana—e bōpa tsela eo re atamelang odara e ’ngoe le e ’ngoe ka eona.
Matla a rona a qala ka kopanyo e otlolohileng. Barekisi ba bangata ba fana ka lisebelisoa tsa kantle, ho etsa machining kapa ho qeta. Re laola tsena tse tharo setsing se le seng se lumellanang le ISO Qingdao. Seo se bolela hore ha ho na handoffs pakeng tsa barekisi-'me ha ho na likheo tsa traceability. Ha moreki a romella lits'oants'o tsa GD&T bakeng sa mochini o tsamaisang lisebelisoa tse sebelisoang libakeng tsa leoatle le lipompo tsa seretse sa khase, sehlopha sa rona se netefatsa boemo ba thepa (ASTM A48 Class 30 vs. Class 40), se etsisa ho fokotseha ha solidification ka hlobo ea lehlabathe, mananeo a CNC a nang le mekhoa e mengata ea ho ts'oara ± 0.015 mm ka mor'a hore ho be le li-final runouts, 'me li-final runouts.

Tsena ha se likarolo tse kantle ho sethala. Ba batla taolo e nepahetseng ea graphite morphology molemong oa ho akhela tšepe, e lateloe ke ho siloa ha profaele ea involute le libaka tse thata tsa ho jara. Re sebelisa lehlabathe le letala bakeng sa ho tiea ha sebopeho, ebe re sebelisa meno a li-gill-mill mochining oa li-axis tse 5 tse nang le tlhahlobo ea Renishaw - ha e tokisoe ka letsoho. Bareki ba Amerika Leboea le Jeremane ba tiisa: lihlahisoa tsa rona tsa pele likarolong tsena ke karolelano ea 94.7%, eseng tloaelo ea indasteri ea 72-78%.
Ba bang ba ka 'na ba pheha khang ea hore mekhatlo ea malapeng ea U.S. kapa EU e fana ka linako tse potlakileng tsa ho etella pele. Empa ha OEM ea Europe e hloka lihlopha tse 42 tsa li-valve tsa khatello ho QT450-10 ductile iron-e nang le libore tse 12 tse hlokang mamello ea ± 0.01 mm - re ile ra fana ka matsatsi a 28. Joang? Hobane ts'ebetso ea rona e nyalisitsoeng ea ho lahla-machining e felisa ho lokisa bocha. Re etsa libopeho tse haufi le marang-rang ka li-locator tse kopaneng, ebe re kenya likarolo tsohle tse sebetsang ka setaele se le seng. Ha ho ts'ebetso ea bobeli.
