Machined iron castings can be specified with dimensional requirements, material condition and quality-planning scope in one request. This customizable grey-iron and ductile-iron sand-casting enquiry includes CNC lathe and milling-center work for industrial machinery, automotive and electrical applications.

Assign machining limits to the drawing dimensions

The stated machining references are ±0.005 mm and ISO2768-mk. Identify the dimensions governed by an individual limit and those governed by the specified general-tolerance requirement. CNC lathe and milling-center operations should be defined around the component's actual interfaces and their finished acceptance dimensions.

Select the iron and heat-treatment condition

Choose grey iron or ductile iron with the grade required by the design. Annealing, quench-and-temper and ADI are named heat-treatment enquiries to select for the appropriate material and required condition. Define that condition in the component specification rather than treating every option as a treatment for every iron casting.

• Provide the part drawing, grade and required quantity.
• Identify CNC-turned and milled interfaces.
• Allocate individual tolerances and the ISO2768-mk requirement.
• Select heat treatment and the required delivered condition.
• Specify zinc plating, painting or powder coating where required.
• Identify quality-planning deliverables and inspection acceptance.

Plan coating around the finished interfaces

Zinc plating, painting and powder coating are surface-treatment choices. Identify the selected finish and any mating or measurement areas requiring particular instructions. The final drawing requirements should address the component in its supplied condition.

Define the quality-planning deliverables

PFMEA, PPAP, APQP, control plan and MSA are included in the stated quality-control scope. Identify which deliverables the project requires and how they relate to the component's acceptance criteria. This gives the automotive, machinery or electrical enquiry a defined planning and inspection basis.
