Essential Guide to Ordering CNC Machined Parts for Your Projects


CNC (Computer Numerical Control) machining is a crucial process for creating precision parts in various industries. Understanding how to order CNC machined parts efficiently is essential for project success. This guide outlines the key steps to take when ordering these parts.

Step 1: Design and CAD Models

Your journey starts with a detailed design. Use CAD (Computer-Aided Design) software to create precise 3D models of the parts you need. Your design should include all critical dimensions, tolerances, and material specifications.

Step 2: Material Selection

Choosing the right material is vital. Consider factors like the part's intended use, strength requirements, and any necessary certifications. Common materials for CNC machining include aluminum, steel, brass, and plastics.

Step 3: Choosing a CNC Machining Supplier

Selecting the right supplier is crucial. Look for suppliers with the right capabilities, experience, and a portfolio that aligns with your project needs. Consider their machinery, quality control processes, and lead times. ProcureStack can assist in connecting you with qualified suppliers.

Step 4: Requesting a Quote

Provide your CAD models and specifications to potential suppliers for a quote. Be clear about quantities, lead times, and any post-processing (like anodizing or painting) requirements. Compare quotes not just on cost, but also on quality and reliability.

Step 5: Prototyping and Revision

If possible, start with a prototype. This allows you to test the part in its intended application and make any necessary revisions to the design or material selection.

Step 6: Finalizing the Order

Once you are satisfied with the prototype, you can move forward with the final order. Communicate any last-minute changes and confirm the delivery schedule.


Ordering CNC machined parts requires careful planning from design to supplier selection. By following these steps, you can ensure a smooth process and receive high-quality parts that meet your project's specifications.
