The finish option with the quickest turnaround. Parts are left with visible tool marks and potentially sharp edges and burrs, which can be removed upon request. Surface finish is comparable to 125 uin Ra finish.
The part surface is left with a smooth, matte appearance.
Type II creates a corrosion-resistant finish. Parts can be anodized in different colors—clear, black, red, and gold are most common—and is usually associated with aluminum. Type III is thicker and creates a wear-resistant layer in addition to the corrosion resistance seen with Type II.
This is a process where powdered paint is sprayed onto a part which is then baked in an oven. This creates a strong, wear- and corrosion-resistant layer that is more durable than standard painting methods. A wide variety of colors are available to create the desired aesthetic.

The most widely used type of CNC milling machine. The full use of the X, Y, and Z directions makes a 3 Axis CNC mill useful for a wide variety of work.
This type of router allows the machine to rotate on a vertical axis, moving the workpiece to introduce more continuous machining.
These machines have three traditional axes as well as two additional rotary axes. A 5-axis CNC router is, therefore, able to machine 5 sides of a workpiece at in one machine without having to remove the workpiece and reset. The workpiece rotates, and the spindle head is able to also move around the piece. These are larger and more expensive.
Using the latest CNC machines, Xometry produces highly accurate, quick turn parts in as fast as 1 day. We also instantly quote CNC machined parts, cutting days off of your RFQ process.
Offers high-precision tolerances ranging from +/-0.001″ – 0.005″, depending on customer specs. We are the experts in making parts that are truly custom and ready to use.
CNC Machining is perfect for prototyping and production production parts. Xometry's massive scale can help you scale up from testing phase to production runs of 100,000 parts of more.
Choose from over 50 metal and plastic materials. CNC Machining offers a wide variety of certified materials.

The Basics Of CNC Mills
CNC mills are automated cutting machines using a rotating spindle-head to cut away unwanted material. CNC milling machines come in a variety of sizes and different axis configurations. They are mainly utilized to cut harder metals but can work with workpiece materials ranging from plastic and aluminum to stainless steel and titanium.
How CNC Milling Works
CNC mills excel at profile cutting harder materials. Like all CNC machines, a CNC mill is controlled with G-Code created through CAM software. The Gg-Code instructs the machine where to move the tool head, how fast to spin the tool, how deep to cut, how to move the workpiece, and other factors relating to speed, feed rate, and coordination. The G-Code complexity depends on how many axes the milling machine has.
Mills can still be used for profile cutting of softer materials, but are not as cost-effective for that use as CNC routers. The main difference between these machines is that with a CNC router the workpiece remains stationary while the router cutting head is directed around the piece, while a CNC mill may move both tool head and workpiece. CNC mills are mainly used in industrial manufacturing, while CNC routing is more common for lower output manufacturing like woodworking.
Choose from millions of possible combinations of materials, finishes, tolerances, markings, and certifications for your order.
Get your parts delivered right to your door without the hassle of sourcing, project management, logistics, or shipping.
Only the top 6% of shops that apply to become Partners make it through our multi-tiered qualification process, so you can be confident your part will be made right.
CNC milling machines are built for precise manufacturing and repeatability which makes them perfect for rapid prototyping and low-to-high volume production runs. CNC mills can also work with a variety of materials from basic aluminum and plastics to more exotic ones like titanium — making them the ideal machine for almost any job.
