In the subtractive manufacturing process, layers of material are removed from a stock piece to produce a custom part. The process is suitable for a range of materials, including wood, plastic, and metals. Ultimately, the automated nature of CNC machines makes it possible to produce parts very accurately.

However, operating CNC machines in-house requires technical expertise and high upfront cost. That’s where this list of CNC online services comes in!

In picking machining shops, we took the following into consideration:

  • Experience: Choosing a provider who has been in the machining industry longer will save you time and money. A company with more skill and experience will likely satisfy your needs with less hassle, even giving suggestions when they see potential problems.
  • Capability: Regardless of time, capability matters a lot. Do they have the complete set of CNC machines (grinding machine, turning machine, milling machine, etc.) needed for your project? Often you will get better pricing, a quick turnaround time, and high precision parts when you work with a provider with excellent machining capability.
  • Quality Control: Quality control is the litmus test of how good the quality will be. The degree of quality control should be at an acceptable or appropriate level.
  • Prototype Availability: A prototype or sample is an excellent way of knowing the machining capability of the CNC online service.
  • Customer Service: Communicating with the machining company should be very easy. They should stick to deadlines, listen to your needs, be helpful, and you should enjoy working with them.

Of course, not all of the online CNC services listed here perfectly meet all the qualities listed above, but each meets at least one or two conditions, and all have a proven track record.

3D Hubs recently added a CNC machining service because they figured the opportunity for custom, on-demand manufacturing is much bigger than 3D printing alone. The CNC machining model is similar to their 3D printing business model: Independent CNC service providers connect to a community network and receive tasks from customers through the company’s extensive network. 3D Hubs updates prices based on material and location and also specifies turnaround times.

They offer the following finishes: Smoothing, anodizing, powder coating, electropolishing, brushing, black oxide/blackening, hardcoat anodizing, bead-blasting, and many more.

Advantages of Using 3D Hubs:

  • Works with ISO9001-certified manufacturing partners on request.
  • Upon request, tolerances up to .0008” (0.020mm) are available. Tighter tolerances get examined on a case-by-case basis.
  • The quality assurance is top-notch: Batch inspections in concurrence with ISO2859, inspection reports in every order, and a NDA agreement with all the manufacturing partners.
  • Operates at a global scale and provides automated pricing, which is a good representation of the “real-time” market price for manufacturing a part.
  • Customers can get quotes in seconds, and custom parts are delivered in days.

Materials: A wide range of metals, including brass, alloy steel, titanium, mild steel, tool steel, aluminum, and stainless steel; as well as a wide range of plastics, including POM (Delrin), nylon, PTFE (Teflon), PEEK, polyethylene, ABS, polycarbonate, and PVC.

CNC Capabilities:

3D Hubs has a network of manufacturing partners that gives customers easy access to diverse machining capabilities for all manufacturing needs.

  • CNC Milling Service: They have 3-axis, 3+2 axis and full 5-axis milling centers which allow you to produce highly accurate parts to meet your most stringent requirements. Five-axis milling centers, for example, are capable of producing parts with complex geometries and will significantly increase productivity by reducing the number of machine setups.
  • CNC Turning Service: CNC turning processes remove metal or plastic from parts to produce cylindrical features. 3D Hubs has a wide range of CNC lathes and turning centers that will let you create highly accurate parts. CNC turning machines provide low-cost parts for cylindrical geometries, and live tooling is an option for more complex parts. This is assessed on a case by case basis.
