ToleranceCustomer's Drawing Request
Grey-iron impeller and industrial-machinery sand-casting enquiries name GJL20, GJL25, GG20 and GG25, with separately specified ductile iron also in scope. Select the actual iron family and complete designation for the component. The named labels should be tied to their governing standard rather than treated as automatic equivalents.
Describe the impeller through its working geometry
Show the mounting interface, overall form and passages relevant to the component’s function. Identify the locating datums and the dimensions needed to fit the adjoining assembly. Any rotating-service checks should follow the actual design requirement, with the accepted supplied condition clearly stated.
- Provide the controlled drawing and required quantity.
- State the full grade and applicable material standard.
- Mark assembly-critical dimensions and measurement references.
- Identify material, dimensional and surface acceptance records.
Use drawing tolerances for the finished requirement
Dimensions are customized and tolerances follow the customer drawing. Distinguish areas accepted as cast from interfaces where additional work is requested. This gives the enquiry a clear boundary between the cast component and any further operations needed to achieve the final geometry.
Agree the inspection and approval record
Quality control is stated as 100% inspection under an ISO9001-system reference. Specify which checks are required for the selected impeller or other machinery part and identify applicable qualification documents and scope. If a sample is approved, connect that approval to the same drawing revision, grade and supplied condition used in the order.
