Some industries such as aerospace, electronics, automotive, oil and defense routinely contract out their machining needs to save money. Outsourcing your machining jobs can be a way to achieve a quick turnaround, keep prices competitive and offer your customers excellent service.
Look into a number of machining companies to see which ones best fit your needs. Keep several things in mind when you're checking out machining services.
1. Machining companies use a variety of materials removal machinery, so familiarize yourself with the kind of materials removal machines that work best for your product.
2. A machining service may have particular materials they work with. Find out what the best material is for the part you're having them make, both in terms of cost and quality.
3. Some contractors specialize in prototypes, so hire one of them if your company has just designed a new product.
4. Machining service companies may work primarily with a particular industry. Make sure you find a contractor who is familiar with your type of business.
Action Steps
The best contacts and resources to help you get it done
Compare CNC machining info and conventional machining info for your product
Production machining may involve the use of conventional machine tools or CNC machining centers. If you're looking for simple production, you can probably go with conventional machining. However, if you need a complex part completely made, find a CNC shop because the computerized control allows for accurate, intricate design. More than 80% of manufacturing companies have at least one CNC machine tool.
I recommend: Integrated Engineering Solutions uses CNC vertical milling machines, CNC lathes and EDM machining for customers who need anything from a single piece to quantities requiring close tolerances.

Find machining services for your materials
Precision CNC machinists preferred brass in the past, but new equipment and capabilities have opened up the machining industry to other materials. The environment of the industry and the applications of your product can limit what materials you can use for your product. A good contractor can guide you to the right materials.
