Direct answer: Zhengna Technology supplies custom CNC machined parts for automated assembly machines and robotics, including aluminum, steel, and stainless steel components made from buyer drawings. The sourcing focus should be tolerance stability, surface finish, assembly fit, and repeatable inspection.
| Buyer check | Why it matters |
|---|---|
| Functional surfaces | Identifies datums, bearing faces, threaded holes, and alignment features. |
| Material and heat treatment | Controls strength, wear, weight, corrosion resistance, and machinability. |
| Tolerance stack-up | Prevents assembly drift in robotic and automated equipment. |
| Surface finish | Affects sliding, sealing, coating adhesion, and visual quality. |
| Inspection report | Confirms critical dimensions before shipment and repeat orders. |
Common parts include brackets, blocks, shafts, housings, plates, guides, spacers, fixtures, and robotic end-effector components.
Zhengna Technology supports aluminum, steel, stainless steel, brass, copper alloys, and other materials according to drawing and application requirements.
Buyers should audit datum definition, tolerance stack-up, machining route, inspection method, finish requirements, and packaging protection.
