ToleranceCustomer's Drawing Request
OEM/ODM industrial iron-component enquiries include GG20, GG25, GJL20 and GJL25 references for gray-iron selections, with ductile iron separately specified. Sand casting and CNC machining can be defined for the actual drawing. Choose the complete governing grade and required supplied condition for the machinery part.
Keep the iron family and grade explicit
Identify the document and material condition required by the component’s duty. The grade labels should be matched to their full specification rather than treated as interchangeable iron families. Show the functional geometry explaining how the part mounts, locates or contacts adjacent machinery components.
Assign CNC work to controlled dimensions
Sizes are customized and tolerances follow the customer drawing. Mark the datums, dimensions and measurement stage for the interfaces requiring final work. Distinguish cast-state acceptance from finished geometry, with the required surface condition included in the part definition.
- Provide quantity and the controlled revision.
- State the complete material requirement.
- Mark working and visible faces.
- Define material and dimensional approval records.
- Explain what a sample is intended to demonstrate.
Set inspection and system scope
The stated 100% inspection under an ISO9001-system reference should address agreed characteristics and acceptance records for the selected component. Request applicable documentation scope alongside the actual checks needed for approval. Retain the same grade, drawing and delivered-state definition for sample and production acceptance so the industrial casting has an explicit order basis.
