What is CNC Machining?
CNC Machining is a subtractive manufacturing method that uses cutting tools to remove material from a block of raw material or a pre-existing part (such as a 3D-printed part when very tight tolerances are needed in specific areas).
Capacity = Speed
Our capacity allows us to create CNC-machined parts with unrivaled speed.
At the same time, our experienced engineers ensure the highest standards with cutting-edge software and equipment.
Capacity = Variety
We operate more than 20 state-of-the-art machining centers with a wide variety of CNC equipment such as single-axis lathes.
Single-axis lathes are ideal for executing round parts such as nozzles, engine components, and thread shafts.
Our CNC machining centers also utilize cutting-edge 5-axis machines, which substantially reduce turnaround time by eliminating intermediate setups and enabling undercuts and off-axis features.
CNC Machining Is Complementary to Technology
We also utilize CNC Machining as a valuable secondary operation for our 3D printed parts that require boring, drilling, face milling, or other precision machining for enhancing features.
We are dedicated to providing the fastest CNC machining in the industry, with projects programmed and starting the same day as ordered.
Precise Finishing for CNC Machined Parts
We offer a variety of expertly applied finishing options to improve the mechanical and aesthetic properties of your CNC machine component, including painting, anodizing, EMI and RFI shielding, and hand polishing.
Plastic Materials for CNC Machining
Low-cost engineering plastic that is easy to machine and fabricates
Engineering plastic with excellent dimensional stability and good strength and stiffness over a wide range of service temperatures.
Polycarbonate 20% GF

Frequently Asked Questions About CNC Machining
How large a part can your CNC machines accommodate?
We offer cutting-edge CNC machining with single-cut envelopes up to 84”, 40”, and 36”. but that’s not a limit on the size of your project.
One advantage of partnering with Jamesli Direct Manufacturing is that we have expertise in breaking up complex designs into multiple components, which we can later assemble.
What are your standard tolerances for CNC machined parts?
Standard tolerances for CNC machined parts are +/- 0.005” or 0.001”/”, whichever is greater. In some circumstances, tighter tolerances can be achieved depending on part design.

Standard Tolerances for CNC Machining in Jamesli
Precision is key in many industries. If you have a product that must fit with or in another part to create a finished part, then machined tight tolerances are imperative. CNC machined product adheres to the measurements needed for processes after order completion. The tolerance that can be held with plastics and metals is all less than a sheet of paper.
CNC Machining Applications
Because CNC machining can cut a high variety of fully dense, durable materials like aluminum 5052 and stainless steel, it is perfect for creating fixtures or molds.
The range of affordable metal alloys (like aluminum 6061) and plastics (like acetal or ABS) combined with the speed of our skilled machinists makes our online CNC machining services a great option for prototyping.
Performance-enhancing finishes, precision tolerances as low as +/- 0.001”, and certifiable material options make CNC machining an excellent technology for end-use parts.
