Machine Shop Sourcing Guidelines
Tips On Finding the Right Service Provider for Your Project
While there are numerous CNC machining companies, not all have the same capabilities nor the same expertise in manufacturing precision components. Like many other manufacturing companies, they have their niche in what they have the most experience in and utilize an array of CNC methods to grow their business and provide superior quality machined parts and components. The culmination of CNC technologies allows manufacturers to focus specifically on industries like medical device, aerospace, defense, oil and gas, food industry, electronics and so on. Many do provide services for multiple industries and applications, while others focus on a diverse clientele producing components and offering quick turn with low volume. The diverse CNC manufacturing industry can be challenging to select a service provider when a customer is seeking support. There are numerous online search engines specifically supporting CNC manufacturing businesses. These are a great resource and will list companies and include links to prospective websites with email and phone information. However, they don’t tell you how to determine what shop is best for your project. The following are key factors to consider in choosing a CNC shop:
- Capabilities and Equipment: Ensure the shop has the machinery and software suited for your project. This includes the type of CNC machines (milling, turning, etc.). Can they handle 2D profiles from sheets of metal alloys like tungsten, aluminum and stainless or do they specialize in plastics or non-metallic materials? Some shops specialize in more complex 4 and 5 axis components.
- Quality Control: Look for a shop with a robust quality control system, including inspection equipment and procedures to meet your requirements. Are they certified under ISO-9001-2015, AS9100 or ITAR registered? Many shops are, but not all. If your project requires quality management, these certifications will be required.
- Services Offered: Some shops provide additional services like project management, design assistance, and finishing. Consider if these are necessary for your project.
- Accuracy and Precision: CNC shops excel at producing high-quality parts. If your project demands tight tolerances, choose a shop with experience in high-precision machining.
- Communication: A good shop should be clear and upfront about pricing, turnaround times, and any potential challenges with your project.
- Customer Service: Look for a service provider who values your business and is responsive to your questions and concerns.
Additional Tips:
- Get Quotes: Obtain quotes from several shops to compare pricing and services.
- Shop Reputation: Research online reviews and ask for recommendations from engineers or other professionals in your field.
- Location: Consider the shop’s location if on-site visits or quick turnaround times are crucial for your project.
Vetting potential service providers through online research will save you time and frustration. If your project is a small precision component and you see online that the CNC shops do large scale manufacturing, you can bet this is not a good fit for you. You might have a project that is in an R&D stage, while many shops can support this, there are those that excel in low volume production manufacturing. Some work and time in the beginning will give you an advantage to learning what CNC machined components provider is going to take your project forward with the cost and lead time agreeable to both parties.
