3 Mistakes to Avoid When Ordering CNC Machined Parts

When you order CNC-machined parts, planning and accuracy are important. It doesn't matter if you are producing aerospace components, custom aluminum castings, or intricate shapes from custom aluminum extrusions suppliers; the quality of the final product depends significantly upon how you approach the ordering process. Small mistakes at the beginning can lead to expensive delays, reworks, or poor performance in the final product. At Offshore Direct Metals, we spare customers these pitfalls by getting all the details right the first time.
Mistake #1 - Submitting Incomplete or Incorrect CAD Files
The beginning of accurate CNC-machined parts is accurate design files. If your CAD files lack complete dimensions, tolerances, or other critical specifications, manufacturers can't create exactly what you intended. Minor errors can result in considerable variation in fit or function, especially for complex products like custom aluminum castings.
To avoid this, review your CAD files twice before sending them to your custom aluminum extrusions suppliers. Make sure that every measurement is legible, tolerances are noted, and the format will be readable by the shop's systems. A simple confirmation with your machining partner can spare you costly rework.
Mistake #2 - Not Paying Attention to Material Specifications
Choosing the wrong material is another common and costly mistake. The right alloy or composite affects durability, weight, and resistance to the environment. For example, certain custom aluminum castings are best for high-strength applications, while other aluminum alloys may be best for corrosion resistance.
Working hand-in-hand with custom aluminum extrusions suppliers with experience ensures you select the best material for your project. This not only optimizes the performance of your CNC-machined parts but also enables you to control costs and lead times.
Mistake #3 - Failing to Consider Lead Times and Production Capabilities
Regardless of impeccable files and accurate materials, production schedules will ruin your project if they are unrealistic. High-precision CNC-machined parts require special tooling, programming, and quality checks, none of which can be rushed without compromising results.
By being aware of your supplier's capacity and lead times, you'll avoid missed deadlines. At Offshore Direct Metals, we work with customers to set realistic expectations so custom aluminum castings and complex designs from custom aluminum extrusions suppliers are delivered on time without a quality compromise.
