Engineering hardware can be specified as a sand-cast iron component with selected CNC-finished interfaces. This custom service covers grey-iron and ductile-iron casting enquiries. Define the hardware geometry, iron grade and finished dimensions so the requested casting and machining work can be reviewed as one component.
Use assembly interfaces to define the machining request
Identify the surfaces that locate the hardware and the dimensions that control its connection to other parts. Show their drawing references and the limits required after machining. This separates the cast form from the interfaces that establish the finished component's acceptance.
Select grey or ductile iron through the design requirement
Name the required iron family, grade and applicable material standard. Describe the hardware's function and relevant operating duty so the material selection has a clear basis. The two iron families are separate choices, with the selected grade carried consistently into the drawing and purchase specification.
- Identify the engineering-hardware component and drawing revision.
- Specify the iron family, grade and requested quantity.
- Mark CNC-machined interfaces and numerical limits.
- Describe the required supplied condition and acceptance checks.
Make the precision requirement measurable
A precision enquiry needs dimensional limits on the actual geometry rather than an assumed general accuracy. State the inspection requirements for the machined interfaces and any casting dimensions critical to the design. Include the required delivered surface condition and clarify any additional work requested in the quotation. These details give purchasing a defined component specification for the custom iron hardware.
