Manufacturing has changed radically in recent years as emerging technologies launched the Fourth Industrial Revolution, widely known as Industry 4.0.

Computer vision, machine learning, IoT, and artificial intelligence enable new levels of precision manufacturing for the benefit of all industries. Computer Numerical Control (CNC) machining leverages these technologies to provide high-precision manufacturing for a wide range of industries that depends on a high-quality end product.

Plenty of CNC machine service companies have emerged in recent years, but choosing a less-than-ideal partner might result in products that lack the precision, quality control management and the durability you need.

How can you find the best precision CNC machining parts factory that meets and exceeds your expectations? Keep reading to learn how to find the right CNC machining partner.

What Makes a Great Custom CNC Machining Service Supplier

Precision CNC machining relies on having the right technologies, experienced team, certifications, and quality control methods in place to fulfill a customer’s orders on time and with the highest quality.

Let’s break down how you can evaluate a potential machining service provider to determine if they have everything you’ll need for reliable and high-quality CNC machining.

Industry Licenses and Certifications

Begin by evaluating the potential supplier's licenses and certifications. You need to partner with CNC machining company that has the proper industry certifications to manufacture your products without risking your compliance.

For example, GN Corporation has several essential manufacturing certifications, including:

• AS9100D
• ISO 9001:2015
• ISO 45001:2018
• ISO 14001:2015
• Controlled Goods Program

You’ll likely need to keep looking if a potential machining service supplier doesn’t have the right certifications. You may risk your compliance or be unsure if their manufacturing processes will produce high-quality results.

Experience and Reputation in the Manufacturing Industry

You need a supplier of high precision CNC machining parts with industry experience and a proven track record in manufacturing. Here is what to keep in mind when looking for a precision machining services supplier:

• How long have they been in the manufacturing industry?
• Do they display past or current customers on their website?
• Ask your existing peers and partners about the company. Have they heard of them or worked with them directly?
• What does the machining shop do to ensure on-time delivery?

It’s well worth performing due diligence before agreeing with a partner, and CNC machining is no exception. Look into their reputation and experiences from past customers before signing any agreements.

CNC Machining Tools and Capabilities

CNC machining involves having the right tools, technologies, and staff to provide customers with dependable results. What equipment and training does the potential precision CNC machining manufacturer have in place?

An ideal partner will either have their machining equipment displayed on their website or be able to provide them upon request. If not, it’s not worth risking moving forward with a partner that doesn’t have the equipment you need.

Product Quality and Turnaround Times

Ultimately, the two most important factors about a potential precision CNC machining parts factory are delivering your order on time and meeting the highest quality standards for the end product. Failing to achieve both goals will leave you lacking, falling behind your schedule or with a low-quality product.

Thoroughly evaluating each of the above items can help determine if a potential partner offers a combination of quality, turnaround time and competitive prices to meet your goals. Additionally, it’s worth doing a trial or limited agreement to see how they handle your order before entering into long-term agreements.

What Do Precision CNC Machining Services Cover?

The potential partner’s CNC machining services should cover the precise requirements of your project. Some standard requirements in various industries include:

• Medical: MRI machines, research equipment, and implants depend on high-precision services and may require the partner to have the proper certifications.
• Automotive: Building prototypes or manufacturing specialized parts for the automotive industry may need specialized equipment.
• Aerospace: Many components involved in aircrafts demand high-precision manufacturing of complex aerospace parts with a durable finished product.

Your future partners should have everything necessary to cover the needs of your industry and specific product. You may also want value-added services to cut down on transportation between different partners. A few standard services to consider are:

• Welding
• Complete Assembly
• Zinc Phosphate Coating
• Liquid Penetrant Inspection
• Magnetic Particle inspection
• Hard Facing
