Each component is quoted separately against its own drawing and specification. Assembly-level operating requirements are used to understand the application, but final design responsibility and validation remain with the customer.\u003c\/p\u003e\n\u003ch3\u003eDrawing and manufacturability review\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Grade, condition and governing standard.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStarting form:\u003c\/strong\u003e Forged, cast, bar or other specified blank.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProcess route:\u003c\/strong\u003e Machining, gear processing and other required operations selected after drawing review.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeat treatment and finish:\u003c\/strong\u003e Included only when specified by the released requirements.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCritical controls:\u003c\/strong\u003e Datums, fits, gear data, geometric tolerances, surface roughness and marked characteristics.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSupply plan:\u003c\/strong\u003e Prototype needs, production quantity, annual demand and delivery schedule.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eManufacturing process coordination\u003c\/h3\u003e\n\u003cp\u003eGearbox and engine parts often require several operations to be coordinated around the same datum structure. Jinhua Machinery reviews how the selected starting form, machining allowance, gear features, heat-treatment condition and final inspection interact before quotation. This review is intended to identify missing inputs and establish a repeatable process route; it does not replace the customer’s product design or assembly validation.\u003c\/p\u003e\n\u003ch3\u003eQuality inspection\u003c\/h3\u003e\n\u003cp\u003eInspection requirements are defined per part.
