Why Choose Premium CNC Machining Services?

Why should you even care about your choice of CNC machining services provider in the first place? There are a few reasons:

  • CNC machine shops vary widely in terms of quality, tools and areas of specialty.
  • Poor work during the machining phase can have a negative ripple effect on all remaining phases of production.
  • Your reputation — not just the CNC machinist’s reputation — is on the line with every part and product you release.

That leaves you with one option: You have to find the best CNC machining partner for the job. 

Selecting a CNC Machining Service Partner: 5 Key Steps

How, exactly, do you go about selecting the best CNC machining partner for your device? By following these five steps:

1. Assess Their Capabilities

Think of the CNC machinists you are considering as job applicants. They want your contract and the money that comes with it, and you have to “hire” the best one. What do you do when you’re hiring? You conduct interviews.

So, interview the partners you are considering. Ask them directly about their experience with CNC machining:

  • How many years have they been offering CNC machining services?
  • Have they completed machining jobs on components in your specific industry?
  • Can they point you to any past customers to speak with?

These kinds of questions can yield revealing answers, especially when the machinist would rather not answer the questions in the first place. If you sense that they’re dodging the question or exaggerating their answer (or simply not answering in a way that inspires confidence), it’s likely going to be worth your time to speak with some other providers. 

2. Look at the Tools and Software

There’s more than one way to machine metal parts. In fact, there are all kinds of mills and methods, as well as an enormous number of pieces of software to control CNC machine operations. 

First, you need to ensure that any partner you are considering has the basic types of tools necessary to complete the job. Even if they say they could acquire the right tools, that immediately tells you that they don’t have in-depth experience with the tools in question. And that’s not good.

Meanwhile, the software needs to be cutting-edge. Whether it’s operations software or quality control software, serious CNC machine shops invest in the best platforms to make sure they put out only their best work.

3. Ask About Quality

Don’t just ask what the provider you are considering aims for in terms of quality — ask what they actually achieve. Also, ask them about their quality system and customer ratings. 

If they’re a CNC machining services provider worth working with, they will be excited to answer both of these questions. They should have impressively high quality numbers and low numbers of quality escapes. And they should be able to speak at length about the quality system they have built.

4. Opt for Vertical Integration

CNC machining is a critically important part of the manufacturing process for a wide variety of devices, but it’s just one part. There are various other processes for you to oversee and find providers for, and each can come with its own set of headaches.

What if you could skip a few steps here? If you find a CNC machining provider who has vertically integrated several other manufacturing processes, you certainly can. Modus, for example, has built the proprietary SigShield process to incorporate four unique manufacturing processes under one roof.

5. Ask for Feedback

If you’re looking for a CNC services provider and have a design ready to go, send it to the partners you're considering and wait a couple of days. The best partners will get back to you with feedback on your design quickly.

This feedback shouldn’t be about the overall look or function of the part; it should be about how manufacturable it is. This is information you absolutely need and can benefit from — eliminating unnecessary machining efforts can save you considerable amounts of money on manufacturing. 

Only the best CNC machining partners will actually offer a Design for Manufacturability review that you can use to improve your device.

How to choose a quality CNC Machining Company

Choosing a quality CNC machining company is an important task. Considering there are nearly 20,000 different machine shops to choose from in the U.S. alone, finding the one that best fits your needs can seem daunting. To help you make an educated, strategic choice, we’ve outlined a few factors to keep in mind when looking for a CNC Machining supplier.

Find your ‘niche’

When choosing a CNC machining company, one of the most important things to consider is your product or project requirements. Not only do you want a CNC machine shop that works in your industry, but you also want to find one that aligns with the quantity of parts you need manufactured. A good place to start is to look at the prospect’s website. On their website, you can check their qualifications, their equipment, and their capabilities, as well as find galleries of parts that they’ve made in the past. Those galleries can help you learn more about the variety of components they handle and the materials they work with.

Once you have identified a few different prospects, you can contact each of them directly to learn more about them! Often the best way to learn about a machine shop is to discuss your project with them.

There are a few different types of machine shops to choose from, usually focused around the production volumes they handle, the industries they specialize in, and the materials they work with. You will want to match your industry and product to their capabilities to find the company that best aligns with your project needs. Let’s take a look at some general types of CNC machine shops. Keep in mind that outside these general types, there are a lot of niche shops that could be a better fit, depending on your project needs. 

Industry Approval

Some industries, such as Aerospace and Medical, have many barriers that a CNC machining company must overcome to be qualified to manufacture parts for them, such as industry-specific certifications. As a result, machine shops that manufacture products for these industries tend to specialize in just one or two of these industries.

Other industries, like the Automotive and Automotive Aftermarket industries, don’t have these ‘barriers to entry,’ allowing the shops that cater to them to spread out into smaller industries–such as firearms, hydraulics, and more. Knowing what industry your product fits in is just as important as the production volume of the part.

Certifications are mandatory for particular industries. These indicate that a trusted and experienced third party has verified that the manufacturer’s quality management system is in place and up to standard and that the manufacturer has the equipment and people to maintain the system.

Some major certifications to keep on the lookout for are:

  • AS–This certification is required for Aerospace manufacturers. It also satisfies the guidelines set by NASA and the DOD, so many manufacturers in the Defense sector also have this certification.
  • ISO –This is the Medical industry’s most common and optimal regulatory certification for manufacturers of medical devices. 

There are other essential certifications out there as well, such as ISO , that you should keep in mind as you’re looking for the right CNC machining company for you. 

Customer Approval

Customer approval becomes the next best thing to consider when it comes to manufacturers who don’t work in industries with specific certifications attached to them–like the Automotive market. 

Many manufacturers have customer testimonials on their websites, or if they work for a large market like Automotive, a sampling of their customer base–especially if they’re partnered with one or more large companies. A broad customer base indicates that the CNC machining company is trusted in the industry or the sectors where they supply CNC machining services. And having a good reputation among large, well-established companies is always a good indicator that the manufacturer is trusted in the market. 

Other important factors to consider

The longevity of a CNC machining company is another key factor to keep in mind. A shop that is well established and has been around for several decades indicates that the company not only has a lot of manufacturing experience but also shows its resilience over the years.

Also, consider the value, not just the purchase price set by the CNC machine shop. The price of the part is rarely the whole picture. Choosing the wrong shop can mean production delays and lower-quality products, which can cause the overall amount you pay for the project to increase significantly. On the other hand, choosing a shop that better fits your needs often means that you’ll receive better value for your money and a higher-quality product.
